1. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?
- A. cantaloupe
- B. eggs
- C. carrots
- D. all of the above
Correct answer: D
Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.
2. A nurse is reviewing the laboratory results for a client who has a history of atherosclerosis and notes elevated cholesterol levels. Which of the following statements by the client indicates the nurse should plan follow-up teaching on a low-cholesterol diet?
- A. "I flavor my meat with lemon juice."?
- B. "I eat two eggs for breakfast each morning."?
- C. "I cook my food with canola oil."?
- D. "I take an omega-3 supplement daily."?
Correct answer: B
Rationale: The correct answer is B. Eggs are high in cholesterol, so someone with elevated cholesterol levels, especially with a history of atherosclerosis, should be cautious about egg consumption. Choices A, C, and D are not as concerning for cholesterol levels. Lemon juice, canola oil, and omega-3 supplements do not significantly impact cholesterol levels compared to consuming eggs regularly.
3. Which cells in the islet of the pancreas are responsible for synthesizing insulin?
- A. Alpha cells
- B. Beta cells
- C. Gamma cells
- D. Delta cells
Correct answer: B
Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.
4. Which gluten-free food choice would be most appropriate for a patient with celiac disease?
- A. Scalloped potatoes
- B. Oatmeal
- C. Eggs
- D. Tortillas
Correct answer: C
Rationale: Eggs are a safe food choice for individuals with celiac disease as they are naturally gluten-free. Scalloped potatoes often contain flour in the sauce, which might contain gluten. Oatmeal can be a subject of debate due to possible cross-contamination during processing, so it might not be safe unless labeled gluten-free. Tortillas are typically made from wheat flour containing gluten, but gluten-free versions are available. However, eggs are universally gluten-free, making them the best choice for individuals with celiac disease.
5. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?
- A. glucagon
- B. ghrelin
- C. leptin
- D. insulin
Correct answer: C
Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
