1. Which of the following amino acids are considered indispensable?
- A. Lysine
- B. Methionine
- C. Tryptophan
- D. Valine
Correct answer: A
Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
2. Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?
- A. vegetable oil
- B. palm oil
- C. coconut oil
- D. canola oil
Correct answer: A
Rationale: Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.
3. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
4. What is the initial major sign of acute renal failure?
- A. Oliguria
- B. Hematuria
- C. Proteinuria
- D. Glycosuria
Correct answer: A
Rationale: Oliguria, or reduced urine output, is often the initial major sign of acute renal failure. This reduction in urine output indicates that the kidneys are not functioning properly. Hematuria (blood in urine), proteinuria (presence of protein in urine), and glycosuria (presence of glucose in urine) are not typically the initial major signs of acute renal failure. While they may be present in certain conditions, oliguria is the most common and critical indicator of acute renal failure.
5. The nurse is caring for a client taking warfarin. Which meal brought in by the client's family is a priority to remove before the client eats it?
- A. Oriental cabbage salad with chicken
- B. Beef enchilada, rice, and beans
- C. Ham and cheese sandwich
- D. Macaroni salad and grapefruit slices
Correct answer: C
Rationale: The correct answer is C. Ham is high in vitamin K, which can interfere with warfarin. Vitamin K can decrease the effectiveness of warfarin, an anticoagulant medication. Choices A, B, and D do not contain high levels of vitamin K and are less likely to interfere with the client's warfarin therapy.
