Correct Answer: B

Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.

Correct Answer: D

Rationale: Obtaining serum acetaminophen levels is critical in determining the level of toxicity and guiding treatment. It helps to assess the risk of hepatotoxicity and determine the need for antidotal therapy with N-acetylcysteine. Assessing the child's level of consciousness (Choice A) is important but obtaining serum acetaminophen levels takes precedence as it directly guides the specific treatment required. Activated charcoal (Choice B) is not routinely used in acetaminophen poisoning. While notifying the poison control center (Choice C) is important, obtaining serum acetaminophen levels should be the immediate action to assess the child's condition and guide treatment.

Correct Answer: D

Rationale: The correct next step for the nurse is to measure the area of crepitus. Crepitus indicates subcutaneous emphysema, which is a serious condition requiring monitoring. Applying a pressure dressing (Choice A) could worsen the condition by trapping air under the skin. Administering an oral antihistamine (Choice B) is not indicated for crepitus. Assessing for allergies to cleaning agents (Choice C) is not the priority when dealing with crepitus and subcutaneous emphysema.

Correct Answer: B

Rationale: Joining a group that focuses on self-esteem is the most important intervention for the nurse to include in the client's discharge plan. This can help the client address underlying emotional issues related to her anorexia nervosa and improve her mental health. Choice A is incorrect because a high-protein, low-carbohydrate diet may not address the psychological factors contributing to anorexia nervosa. Choice C is incorrect as scheduling an outpatient psychosocial assessment is important but not the most crucial intervention for discharge planning in this case. Choice D is also not the priority as teaching relaxation techniques, although beneficial, may not directly address the self-esteem and emotional issues that need to be tackled in this situation.

Correct Answer: C

Rationale: Obtaining a detailed report from the previous nurse ensures continuity of care and that all relevant information is passed on. This is critical in palliative care, where comfort measures and symptom management are key components of care. Choice A is not the most important action in this scenario, as the question focuses on continuity of care within the healthcare team. Beginning comfort measures immediately, as in choice B, is essential but obtaining a detailed report takes precedence to ensure a smooth transition of care. Confirming that the client understands the treatment plan, as in choice D, is important but does not directly address the need for continuity of care through a detailed report.
