1. Which food items should be consumed with nonheme iron to increase its absorption, according to a nurse's education plan for clients?
- A. Kiwi
- B. Strawberries
- C. Coffee
- D. Kiwi and Strawberries
Correct answer: D
Rationale: The correct answer is D: Kiwi and Strawberries. Both of these fruits are high in vitamin C, a nutrient known to enhance the absorption of nonheme iron. Vitamin C facilitates the conversion of nonheme iron into a form that is more readily absorbed by the body, thereby enhancing iron intake. In contrast, coffee (Choice C) contains certain compounds that can actually inhibit the absorption of iron, making it a less desirable choice when the goal is to increase iron absorption. Consequently, Choices A (Kiwi), B (Strawberries), and C (Coffee) were specifically picked to highlight the varying effects of different food items on nonheme iron absorption.
2. Why are blood glucose levels high in type 1 diabetes?
- A. The urinary excretion of glucose is impaired
- B. The lean body mass is metabolized to produce glucose via gluconeogenesis
- C. The absorption of glucose from the gastrointestinal tract is more efficient
- D. There is insufficient insulin to facilitate the transport of glucose into the cells
Correct answer: D
Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.
3. Risk factors that have been shown to contribute to age-related macular degeneration include _____.
- A. oxidative stress from sunlight
- B. iron-deficiency anemia
- C. decreased intake of phytochemicals
- D. vitamin B6 malabsorption
Correct answer: A
Rationale: 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.
4. A patient with an ileostomy is suffering from frequent diarrhea. The clinician should advise the patient to increase his intake of what food to thicken stool output?
- A. celery
- B. salad greens
- C. potatoes
- D. dried beans and peas
Correct answer: C
Rationale: Potatoes are starchy and can help thicken stool output, making them beneficial for patients with an ileostomy experiencing diarrhea.
5. Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?
- A. margarine
- B. milk
- C. cereal
- D. yogurt
Correct answer: A
Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.
