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 preparing to administer a gavage feeding via a nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?

A. Stabilize the tube with tape to the newborn’s cheek.
B. Remove supplemental oxygen during the feeding.
C. Measure the stomach aspirate prior to the feeding.
D. Place the newborn on their left side for 30 minutes after the feeding.

Correct answer: C

Rationale: Measuring the stomach aspirate prior to the feeding is crucial to ensure the correct placement and function of the nasogastric tube. This step helps prevent complications such as aspiration or improper feeding. Choice A is incorrect as stabilizing the tube with tape to the newborn’s cheek can cause discomfort and skin irritation. Choice B is incorrect because removing supplemental oxygen during the feeding may compromise the newborn's respiratory status. Choice D is incorrect because placing the newborn on their left side for 30 minutes after the feeding is not a standard practice and is unnecessary for administering gavage feeding.

3. When administering Tapazole, The nurse should monitor the client for which of the following adverse effect?

A. Hyperthyroidism
B. Hypothyroidism
C. Drowsiness
D. Seizure

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. A nurse is developing a plan of care for a client who has anorexia nervosa. Which of the following actions should the nurse include in the plan?

A. Encourage the client to participate in developing a system of rewards.
B. Arrange for someone to remain with the client for 30 minutes after meals.
C. Offer the client a selection of beverages at each meal.
D. Inform the client that a weight gain of 2.3 kg per week is expected.

Correct answer: A

Rationale: Encouraging the client to participate in developing a system of rewards is an essential part of the plan of care for a client with anorexia nervosa. This action can help motivate and engage the client in their treatment plan, promoting a sense of achievement and progress. Choice B, arranging for someone to remain with the client for 30 minutes after meals, may not address the underlying issues related to anorexia nervosa and could potentially disrupt the client's independence. Choice C, offering a selection of beverages at each meal, is not directly related to addressing the client's condition of anorexia nervosa. Choice D, informing the client about an expected weight gain, could increase anxiety and may not be appropriate without considering the client's individual progress and readiness.

5. Each statement is true of water-soluble vitamins, except one. Which is it?

A. Act as coenzymes
B. Deficiencies develop rapidly
C. Daily intake is necessary
D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
