Correct Answer: C

Rationale: The correct answer is C because administering antiemetic medications like metoclopramide and dexamethasone helps control nausea and vomiting post-chemotherapy. Metoclopramide acts on the gut to reduce nausea, while dexamethasone decreases inflammation and suppresses the vomiting reflex. Choice A focuses on dietary interventions but does not address the physiological cause of nausea. Choice B with breathing exercises may help some clients but does not directly address the nausea and vomiting. Choice D is incorrect as withholding fluids can lead to dehydration, which is not recommended after chemotherapy.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which refers to paleness of the skin, is an early sign of anemia due to decreased red blood cell levels. Anemia causes reduced oxygen delivery to tissues, leading to paleness. Palpitations (A) may occur in anemia but are not an early sign. Glossitis (C) and weight loss (D) are not typically early signs of anemia and are more commonly associated with other health conditions.

Correct Answer: D

Rationale: The correct answer is D because exhaling deeply before using the spirometer is incorrect. The purpose of the incentive spirometer is to encourage deep inhalation to improve lung function. Exhaling deeply before using the spirometer goes against this goal and may hinder the effectiveness of the device. Choices A, B, and C are all correct actions when using the spirometer. Taking two normal breaths helps to prepare the lungs, sitting upright optimizes lung expansion, and inhaling deeply to reach the target helps to improve lung ventilation.

Correct Answer: C

Rationale: The correct answer is C: Comparing the patient’s present weight with her last weight. This is the most direct and reliable method to assess volume depletion due to fluid loss. By comparing the patient's current weight with her last weight, you can easily determine if there has been a significant decrease in weight indicating fluid loss and potential hypovolemia. Explanation of why other choices are incorrect: A: Measuring the quantity and specific gravity of her urine output - This method may provide some information about hydration status, but it is not as direct or reliable as comparing weight changes. B: Taking her blood pressure - While blood pressure can indicate hypovolemia, it may not provide immediate insight into volume depletion caused by diarrhea. D: Administering the oral water test - This test is not commonly used to assess volume depletion and may not be as effective or quick as comparing weight changes.

Correct Answer: C

Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This is supported by stable vital signs and nearly healed incision, suggesting physical recovery. Choice A is incorrect as fear of being alone does not necessarily mean the patient can perform dressing changes independently. Choice B is incorrect as resuming medications is not related to the patient's fear of being alone. Choice D is incorrect as there is no evidence to suggest the surgery was unsuccessful based on the information provided.
