Nursing Elites

1. Which of the following is a poor food source of iron?

• A. Dried fruits
• B. Cheese
• C. Clams
• D. Legumes

Correct answer: B

Rationale: Iron is an essential nutrient for the body, and while it can be found in many different types of foods, the amounts can vary significantly. Cheese, while a good source of other nutrients like calcium and protein, is not a particularly rich source of iron. On the other hand, clams, legumes, and dried fruits are known to contain higher levels of iron. Therefore, among the provided choices, cheese is considered a poor source of iron. It's important to note that a balanced diet should include a variety of foods to ensure the intake of all necessary nutrients.

2. A condition that often progresses to become type 2 diabetes mellitus is:

• A. type 1 diabetes mellitus
• B. high blood pressure
• C. chronic pancreatitis
• D. impaired glucose tolerance

Correct answer: D

Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.

3. A nurse is assessing a client who has malnutrition. Which of the following findings should the nurse expect?

• A. Increased vital capacity
• B. Dry skin
• C. Heat intolerance
• D. Decreased mental status

Correct answer: D

Rationale: Malnutrition can lead to a variety of physical and mental symptoms. One common manifestation of malnutrition is a decreased mental status, which includes confusion, lethargy, and cognitive impairment. Dry skin is a typical finding in malnutrition due to the lack of essential nutrients needed for skin health. Heat intolerance is not a direct consequence of malnutrition. While malnutrition can affect respiratory function, it typically leads to decreased vital capacity rather than increased. Therefore, the correct answer is decreased mental status.

4. Why is bleeding in the leg of a pregnant woman considered as an emergency?

• A. Blood volume is greater in pregnant woman; therefore, blood loss is increased
• B. There is an increase blood pressure during pregnancy increasing the likelihood of hemorrhage
• C. Pregnant woman are anemic, all forms of blood loss should be considered as an emergency especially if it is in the
• D. The pressure of the gravid uterus will exert additional force thus, increasing the blood loss in the lower extremities

5. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.
