Correct Answer: B

Rationale: The correct answer is B. Eating small, frequent meals is a recommended strategy to manage nausea and vomiting during pregnancy. This approach helps prevent an empty stomach, which can worsen symptoms. Option A is not as effective as eating small, frequent meals. Option C is unrelated to managing nausea and vomiting, and acetaminophen should only be taken as directed by a healthcare provider. Option D may help reduce nausea in some cases, but the most appropriate response related to managing symptoms is to eat small, frequent meals.

Correct Answer: B

Rationale: The correct answer is B: 'You may experience a persistent cough while taking this medication.' Lisinopril is known to cause a persistent cough as a common side effect. It is essential for the nurse to educate the client about this potential side effect, as it should be reported to the healthcare provider. Choice A is incorrect because lisinopril is usually taken once daily, but not necessarily at bedtime. Choice C is incorrect because lisinopril can actually increase potassium levels, so taking it with a potassium supplement may lead to hyperkalemia. Choice D is incorrect because antacids may reduce the effectiveness of lisinopril, so it should not be taken with them.

Correct Answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.

Correct Answer: D

Rationale: Placing a pillow under the client's lower legs is the correct intervention because it helps prevent pressure on the incision site and promotes circulation. Elevating the lower legs also aids in reducing swelling and improving blood flow. Applying heat to the incision site (Choice A) is contraindicated in the early postoperative period as it can increase inflammation and the risk of infection. Keeping the client's knee flexed while in bed (Choice B) may lead to contractures or limited extension of the knee joint. Placing a pillow under the client's knee (Choice C) may cause hyperextension of the knee, which is also not recommended post knee arthroplasty.

Correct Answer: B

Rationale: A weight loss of 0.5 kg (1.1 lb) in 24 hours may indicate dehydration or malnutrition, which are critical concerns for a client receiving total parenteral nutrition (TPN). Therefore, the nurse should report this finding to the provider. Elevated blood glucose levels (Choice A) can be managed by adjusting TPN components, WBC count (Choice C) and a slightly elevated temperature (Choice D) are not directly related to TPN administration and may not require immediate intervention.
