A healthcare provider is teaching a client about nutritional requirements necessary to promote wound healing. Which of the following nutrients should the provider include in the teaching?
Select the best answer.
Explanation:
Protein is crucial for wound healing as it plays a vital role in tissue repair and synthesis. Calcium is important for bone health but not directly related to wound healing. Vitamin B1 is essential for energy production but not specifically significant for wound healing. Vitamin D is essential for bone health and immune function but is not a primary nutrient emphasized for wound healing.
What would you do to increase the amount of iron absorbed from a meal?
Select the best answer.
Explanation:
The correct answer is D: 'Consume orange juice as a beverage with a meal'. This is because Vitamin C significantly enhances the absorption of non-heme iron, a form of iron found in plant-based foods. Therefore, consuming orange juice, which is rich in vitamin C, with a meal can effectively increase iron absorption. On the contrary, choices A, B, and C are incorrect. Coffee (Choice A) contains polyphenols that can inhibit iron absorption. Avoiding vitamin C-rich foods (Choice B) would decrease iron absorption, not increase it. While calcium (Choice C) is essential for many bodily processes, it can actually inhibit iron absorption when consumed together.

Select the best answer.
Explanation:
Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
How many grams of protein per day are recommended for a person weighing 150 lbs?
Select the best answer.
Explanation:
The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.
Risk factors that have been shown to contribute to age-related macular degeneration include _____.
Select the best answer.
Explanation:
The correct answer is A: oxidative stress from sunlight. Oxidative stress caused by exposure to sunlight is a significant risk factor for age-related macular degeneration. This condition can result in vision loss among older individuals. Choices B, C, and D are incorrect. Iron-deficiency anemia, decreased intake of phytochemicals, and vitamin B6 malabsorption are not established risk factors for age-related macular degeneration.
How many amino acids are essential?
Select the best answer.
Explanation:
The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

Select the best answer.
Explanation:
Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
Who most often prescribes a patient's diet order?
Select the best answer.
Explanation:
A patient's dietary order is most frequently prescribed by a physician. This is because the physician has a comprehensive understanding of the patient's medical condition and can thus determine the most suitable dietary plan. Registered dietitians often collaborate with physicians in this process, but the final prescription is made by the physician. Although registered nurses, dietetic technicians, and occupational therapists play significant roles in patient care, they typically do not prescribe diet orders.
What is the process of formal negotiations of working conditions between a group of registered nurses and employer?
Select the best answer.
Explanation:
The correct answer is 'collective bargaining.' Collective bargaining involves negotiations between a group of employees, in this case, registered nurses, and their employer to determine working conditions, wages, benefits, and other aspects of employment. Grievance refers to a formal complaint about a workplace issue, arbitration involves a neutral third party making a decision in a dispute, and a strike is a work stoppage by employees to protest against their employer.
Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.
Select the best answer.
Explanation:
The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.
In consideration of the steps in applying the bag technique, which side of the paper lining of the CHN bag is considered clean to make a non-contaminated work area?

Explanation:
Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
What is the most important concern immediately after a myocardial infarction?
Select the best answer.
Explanation:
Immediately after a myocardial infarction, the primary concern is to allow the heart to rest and heal to prevent further damage. This is why choice B is the correct answer. While choices A, C, and D might be a part of the long-term management plan following a myocardial infarction, they are not the immediate priority. Reducing cholesterol and saturated fat intake, as well as adjusting eating habits can help prevent future heart issues, but do not directly contribute to the immediate recovery post-myocardial infarction.
Fires are approached using the mnemonic RACE, in which, R stands for:
Select the best answer.
Explanation:
Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
When assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on the following EXCEPT:
Select the best answer.
Explanation:
The correct answer is B because when assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on various aspects such as the amount of food and fluid taken before treatment to prevent complications during the procedure, teaching the client's relatives to perform the procedure correctly, and following the doctor's orders regarding position restrictions and the client's tolerance for lying flat. Respiratory rate, breath sounds, and location of congestion would be assessed during the procedure itself, not as part of the pre-assessment.
What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?
Select the best answer.
Explanation:
The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.
A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend as the best source of vitamin A?
Select the best answer.
Explanation:
The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.
An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.
Select the best answer.
Explanation:
The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.
Select all that apply. To lower LDL levels, you should:
Select the best answer.
Explanation:
To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.
Which enzyme is most essential for hydrolyzing large protein molecules?
Select the best answer.
Explanation:
Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?
Select the best answer.
Explanation:
The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.
When a nurse signs a consent form, which ethical principle is being observed regarding the patient?
Select the best answer.
Explanation:
The correct answer is 'Autonomy'. Autonomy refers to the patient's right to make their own decisions, which is being honored when a nurse signs a consent form. While beneficence (Choice D) is an important ethical principle that involves acting in the patient's best interest, it is not what is being primarily observed in this instance. Justice (Choice B) refers to fairness and equal treatment and is not specifically relevant to this scenario. Accountability (Choice C) pertains to being answerable for one's actions and decisions, but again, it is not the principle directly observed in this situation. Therefore, when a nurse signs a consent form, it is the principle of autonomy that is being observed.
Which of the following statements about Z-Track technique is false?
Select the best answer.
Explanation:
The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.
Mr. CKK is unconscious and was brought to the E.R. Who among the following can give consent for CKK's operation?
Select the best answer.
Explanation:
In the scenario described, when a patient is unconscious and unable to provide consent, the responsibility usually falls on the physician to make decisions regarding the patient's treatment, including obtaining consent for an operation. While nurses play a crucial role in patient care, they typically do not have the authority to provide consent for a major procedure. The next of kin may be consulted for input, but the ultimate decision-making authority lies with the physician. The patient, being unconscious, is unable to provide consent in this situation.
In the US, low iron intake is often associated with?
Select the best answer.
Explanation:
Diets high in sugar and fat often lack essential nutrients like iron, leading to a risk of iron deficiency anemia, especially when iron-rich foods are not consumed adequately.
Which condition is an example of a potential cause of gastritis?
Select the best answer.
Explanation:
Bile reflux is a potential cause of gastritis as it can irritate the stomach lining when bile backs up into the stomach. Choices B, C, and D do not directly cause gastritis. Low salt intake is not a common cause of gastritis. Hypophosphatasia is a rare genetic disorder affecting bone development, not the stomach. Gallstones, while related to the gallbladder, are not a direct cause of gastritis.
A patient is on a low-sodium diet. Which food item should the patient avoid?
Select the best answer.
Explanation:
The correct answer is B: Canned soup. Canned soup is commonly high in sodium content, which is not suitable for a patient on a low-sodium diet. Fresh fruit, whole grain bread, and grilled chicken typically have lower sodium levels and can be included in a low-sodium diet. Therefore, the patient should avoid canned soup to adhere to the requirements of a low-sodium diet.
A nurse is instructing a group of clients regarding calcium-rich foods. Which of the following foods should the nurse include in the teaching as the best source of calcium?
Select the best answer.
Explanation:
Cottage cheese is the best source of calcium among the options provided. It is rich in calcium and provides a significant amount per serving. 1 cup of cottage cheese contains more calcium compared to 1⁄2 cup of ice cream, 1 ounce of Swiss cheese, or 1 cup of milk. Ice cream is not a significant source of calcium and is often high in sugar and fat. Swiss cheese and milk contain calcium, but cottage cheese has a higher calcium content per serving, making it the best choice for meeting calcium needs.
The nurse is planning education about appropriate protein food choices for a client who has recently been prescribed a renal diet. Which protein food items should the nurse include in the education?
Select the best answer.
Explanation:
The correct answer is D: Poultry, eggs, and fish. These protein sources are high-quality proteins suitable for a renal diet as they provide essential amino acids without excessive amounts of potassium or phosphorus. Choice A, yogurt, seeds, and lentils, may be high in potassium and phosphorus, which could be restricted in a renal diet. Choice B, beef, bacon, and nuts, are also high in phosphorus and may not be ideal for a renal diet. Choice C, peanut butter, beans, and peas, are high in potassium and phosphorus, making them less suitable for a renal diet.
A nurse is planning to teach a client about a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid?
Select the best answer.
Explanation:
Orange juice is high in potassium and should be avoided in a low-potassium diet. Butter, poultry, and yogurt are low-potassium food choices and can be included in a low-potassium diet. Poultry is a good source of lean protein, yogurt is a good source of calcium and protein, and butter is low in potassium. Therefore, the nurse should instruct the client to avoid orange juice as it is high in potassium, which is not suitable for a low-potassium diet.
A nurse is providing dietary teaching for a client who has just learned that she has type 2 diabetes mellitus. The nurse should explain that which of the following sweeteners will add calories to the client's carbohydrate count?
Select the best answer.
Explanation:
Sorbitol is a sweetener that will add calories to the client's carbohydrate count. It is a sugar alcohol that provides about 2.6 calories per gram. Sucralose, aspartame, and acesulfame potassium are all non-nutritive sweeteners that do not contribute significant calories to the diet. Sucralose is about 600 times sweeter than sucrose but does not add calories. Aspartame is a low-calorie sweetener that is approximately 200 times sweeter than sucrose, and acesulfame potassium is a calorie-free sweetener.
A nurse is discussing denture care with the partner of a client who is unable to perform oral hygiene. Which of the following should be included in the discussion?
Select the best answer.
Explanation:
Wrapping gloved fingers with gauze provides a safe and effective method for removing dentures, preventing damage.
What characterizes Obsessive Compulsive Disorder?
Select the best answer.
Explanation:
Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.
Which of the following foods should be avoided by patients experiencing xerostomia, except one? Which is the exception?
Select the best answer.
Explanation:
The correct answer is Dill pickles. Unlike the other choices, which can exacerbate xerostomia due to their dry or irritating nature, dill pickles, being tart and sour, can actually help stimulate saliva flow, which is beneficial for patients with xerostomia. Saltines, salsa, and alcohol are all known to contribute to dry mouth and should generally be avoided by individuals experiencing xerostomia.
To ensure client safety before starting blood transfusions, the following are needed before the procedure can be done EXCEPT:
Select the best answer.
Explanation:
To ensure client safety before starting blood transfusions, taking baseline vital signs, warming the blood to room temperature, and having two nurses verify client identification, blood type, unit number, and expiration date of blood are crucial steps. Consent for blood transfusion is required but is typically obtained before the procedure. The focus before the procedure should be on confirming the right client, blood product, and ensuring the blood is prepared correctly to minimize risks of transfusion reactions.
Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?
Select the best answer.
Explanation:
Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.
Each statement is true of fat-soluble vitamins, except one. Which is the exception?
Select the best answer.
Explanation:
Fat-soluble vitamins are not stored in the pancreas; they are stored in the liver and fatty tissues. Choice A is correct as fat-soluble vitamins are fairly stable to heat. Choice B is also correct as fat-soluble vitamins contain carbon. Choice D is correct as fat-soluble vitamins are absorbed in the intestine along with fats and lipids in food.
A nurse is providing teaching to an obese client who has gestational diabetes and is at 25 weeks of gestation. Which of the following statements made by the client indicates a need for further teaching?
Select the best answer.
Explanation:
The belief that gestational diabetes results in lifelong diabetes is incorrect; it often resolves after pregnancy, though it does indicate a higher risk for developing type 2 diabetes in the future.
A client states they are taking greater than the recommended daily allowance of vitamin E to prevent cataracts. Which complication should the nurse educate the client as related to taking excessive amounts of vitamin E?
Select the best answer.
Explanation:
The correct answer is B: Stroke. High doses of vitamin E supplements have been associated with an increased risk of hemorrhagic stroke due to its blood-thinning properties. Option A, lung cancer, is not a known complication of excessive vitamin E intake. Option C, diarrhea, is more commonly associated with excessive intake of other vitamins or minerals. Option D, liver damage, is not a commonly reported complication of vitamin E overdose.
Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?
Select the best answer.
Explanation:
The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.
A nurse is educating the parent of a preschool-age child about nutrition. Which is the best snack choice for the nurse to recommend to the parent?
Select the best answer.
Explanation:
The best snack choice for a preschool-age child recommended by the nurse would be a mini wheat bagel with peanut butter. This option provides a good balance of carbohydrates, protein, and healthy fats, making it a more nutritious choice compared to the other options. Fruit snacks may contain added sugars and lack essential nutrients. White toast with jelly is high in simple carbohydrates and sugars, providing less sustained energy. Sports drinks are often high in sugar and not necessary for a preschool-age child's snack.
A client with gastroesophageal reflux disease is being taught by a nurse about managing the illness. Which of the following recommendations should the nurse include in the teaching?
Select the best answer.
Explanation:
The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.
Each of the following foods has cariostatic properties, with one exception. Which food is the exception?
Select the best answer.
Explanation:
Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.
A patient who reports stomach ulcers should avoid all the following foods, except one. Which is the exception?
Select the best answer.
Explanation:
Patients with stomach ulcers are advised to avoid foods that can increase stomach acid levels, such as caffeine, proteins, and calcium. Wheat, on the other hand, is generally well-tolerated by individuals with ulcers as it does not stimulate gastric secretions. Therefore, the correct answer is D. Choice A (Proteins), B (Caffeine), and C (Calcium) are not recommended for patients with stomach ulcers due to their potential to exacerbate symptoms.
A nurse is teaching an in-service about manifestations of hypoglycemia to a group of newly licensed nurses. Which of the following should the nurse include in the teaching?
Select the best answer.
Explanation:
Blurred vision is a common symptom of hypoglycemia and should be included in the teaching.
The parent of a child newly diagnosed with lactose intolerance is being taught by the nurse. Which food items identified by the parent indicate an understanding of foods to avoid?
Select the best answer.
Explanation:
The correct answer is B. Milk, cheese, ice cream, and puddings contain lactose, which individuals with lactose intolerance should avoid. Choices A, C, and D do not contain lactose and are not typically problematic for individuals with lactose intolerance.
Which of the following converts starch to disaccharides, and this reaction occurs in the _____?
Select the best answer.
Explanation:
The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.
What level of sodium restriction would be included as part of nutrition therapy for heart failure?
Select the best answer.
Explanation:
The correct answer is 1500 mg to 3000 mg per day. This is the level of sodium restriction typically recommended for heart failure patients. It helps manage fluid retention and reduce blood pressure, which are both crucial in treating heart failure. A sodium intake of less than 500 mg per day (Choice A) might be too restrictive and is not typically recommended. Similarly, an intake of 1000 mg to 1500 mg per day (Choice B) falls short of the recommended range. Lastly, an intake of 3000 to 3500 mg per day (Choice D) exceeds the recommended upper limit, potentially exacerbating fluid retention and high blood pressure.
A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
Select the best answer.
Explanation:
Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.
Which vitamin is crucial for collagen synthesis and wound healing?
Select the best answer.
Explanation:
The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.
Which of the following has the greatest effect on an increase in body weight?
Select the best answer.
Explanation:
Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.
Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?
Select the best answer.
Explanation:
Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.
Which of the following nutrients deficiency may lead to a diabetes-like condition?
Select the best answer.
Explanation:
Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.
_____ neutralizes stomach acid in the small intestine:
Select the best answer.
Explanation:
The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?
Select the best answer.
Explanation:
This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.
Which chemical structure is represented by glycerol combined with two fatty acids?
Select the best answer.
Explanation:
The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.
Where does most nutrient digestion and absorption occur?
Select the best answer.
Explanation:
The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
Why is a pulse oximeter attached to Mr. Dizon's finger?
Select the best answer.
Explanation:
A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
What is tocopherol?
Select the best answer.
Explanation:
Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.
Which organ produces and secretes bicarbonate ions and insulin?
Select the best answer.
Explanation:
The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

The Acceptable Macronutrient Distribution Ranges state that half of your calories should come from protein.
Select the best answer.
Explanation:
The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.
Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.
Select the best answer.
Explanation:
Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.
