Correct Answer: D

Rationale: The left lateral position is the correct choice to promote optimal cardiac output in a pregnant client at 32 weeks gestation with cardiac disease. This position improves venous return and decreases pressure on the vena cava, helping optimize cardiac output. Standing (choice B) would not be recommended as it may decrease venous return. The supine position (choice C) should be avoided in pregnant clients with cardiac disease as it can compress the vena cava, reducing cardiac output and potentially causing hypotension. The chest (choice A) is not a valid position recommendation for optimizing cardiac output in this scenario.

Correct Answer: A

Rationale: A GFR of 14 mL/min indicates significant kidney damage and a severe decrease in kidney function. This level of GFR typically indicates the need for hemodialysis to help the kidneys perform their function adequately. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and managing chronic kidney disease but do not specifically indicate the need for hemodialysis. Therefore, choices B, C, and D are incorrect.

Correct Answer: C

Rationale: The correct answer is C. Low back pain during a blood transfusion is a classic sign of a transfusion reaction, specifically a transfusion-associated circulatory overload (TACO) or hemolytic reaction, both of which require immediate attention to prevent serious complications. Assessing this client first is crucial to ensure prompt intervention. Choices A, B, and D do not indicate immediate life-threatening complications and can be addressed after the client experiencing low back pain during a blood transfusion is stabilized.

Correct Answer: A

Rationale: The correct answer is to wear an N95 respirator mask when caring for the client with TB. This is crucial to prevent the nurse from inhaling the airborne particles that spread the infection. Choice B is incorrect because placing the client in a semi-private room does not address the protection of the nurse. Choice C is incorrect as having the client wear a surgical mask during meals is not sufficient to protect the nurse during all interactions. Choice D is incorrect as using a negative pressure air filtration system is more applicable to airborne infection isolation rooms in healthcare settings and not a standard intervention for nurses caring for a single client with TB.

Correct Answer: B

Rationale: The correct answer is to take the medication with a full glass of water. Alendronate should be taken with a full glass of water to prevent esophageal irritation. Additionally, the client should remain upright for 30 minutes after taking it to prevent potential adverse effects. Choice A is incorrect because alendronate should not be taken at bedtime, but rather in the morning on an empty stomach. Choice C is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because the client should remain upright, not lie down, for 30 minutes after taking the medication.
