1. 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.

2. A nurse is providing MyPlate education to a client newly diagnosed with diabetes mellitus. Which plate chosen by the client indicates the teaching was effective, according to the MyPlate guidelines?

A. 1/2 of the plate is filled with carbohydrate foods, 1/4 filled with protein foods, and 1/4 filled with fruits and vegetables
B. 1/2 of the plate is filled with protein foods, 1/4 filled with carbohydrates, and 1/4 filled with non-starchy vegetables
C. 1/2 of the plate is filled with carbohydrates, 1/4 filled with protein foods, and 1/4 filled with non-starchy vegetables
D. 1/2 of the plate is filled with non-starchy vegetables, 1/4 filled with protein foods, and 1/4 filled with carbohydrate foods

Correct answer: D

Rationale: The correct answer is D. This option reflects the MyPlate guidelines for managing diabetes effectively. In diabetes management, it is essential to focus on non-starchy vegetables, appropriate protein portions, and controlled carbohydrate intake. Option A places too much emphasis on carbohydrates, which may not be suitable for diabetes. Option B swaps the proportions of protein and carbohydrates, which is not in line with the recommended distribution. Option C places too much emphasis on carbohydrates and lacks the emphasis on non-starchy vegetables, making it less suitable for diabetes management.

3. A nurse in a long-term care facility is developing strategies to promote increased food intake for an older adult client. Which of the following interventions should the nurse implement?

A. Offer sugar substitutes to increase the client’s appetite.
B. Provide opportunities to eat three large meals per day.
C. Provide entertainment while the client is eating.
D. Offer finger foods at mealtime.

Correct answer: D

Rationale: The correct intervention for promoting increased food intake for an older adult client is to offer finger foods at mealtime. Finger foods are easier for older adults to manage, making eating less cumbersome and more enjoyable, which can help increase overall food intake. Providing sugar substitutes (Choice A) may not necessarily increase appetite and could have negative health effects. Eating three large meals per day (Choice B) may be overwhelming and not suitable for older adults who may prefer smaller, more frequent meals. While providing entertainment (Choice C) during meals can be beneficial in some cases, it may not directly contribute to increased food intake as effectively as offering finger foods.

4. What is considered fast breathing in a 13-month-old child if the respiratory rate (RR) exceeds which value?

A. 40 breaths per minute
B. 50 breaths per minute
C. 60 breaths per minute
D. 30 breaths per minute

Correct answer: C

Rationale: In the context of pediatric care, a respiratory rate of more than 60 breaths per minute in a child aged 13 months is considered fast breathing, hence option 'C' is correct. Options 'A', 'B', and 'D' are incorrect as they do not meet the specified criteria for fast breathing in a 13-month-old. Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, including monitoring respiratory rates, to ensure that interventions are appropriately targeted and outcomes are optimized.

5. What is the digestive action of lipase?

A. It breaks down carbohydrates
B. It breaks down proteins
C. It breaks down lipids
D. It aids in fat digestion

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.
