Correct Answer: D

Rationale: The correct answer is D because rotating injection sites prevents tissue damage and ensures better absorption of insulin. Option A is incorrect as injecting insulin into the thigh before exercise can lead to hypoglycemia. Option B is incorrect as skipping meals can cause blood sugar levels to drop dangerously low. Option C is incorrect as insulin should not be stored in the freezer as it can alter its effectiveness.

Correct Answer: D

Rationale: The correct answer is D, Varicella. Varicella (chickenpox) is a disease that requires airborne precautions to prevent its spread. Airborne precautions are necessary to prevent transmission of pathogens that remain infectious over long distances when suspended in the air. Rubella, pertussis, and influenza do not require airborne precautions. Rubella and pertussis require droplet precautions, while influenza requires droplet and contact precautions. Therefore, Varicella is the only disease in the list that necessitates airborne precautions.

Correct Answer: A

Rationale: The correct answer is A: Pregnancy status. Raloxifene is a pregnancy category X drug, which means it can cause serious birth defects. Therefore, it is crucial for the nurse to assess the client's pregnancy status before initiating therapy. Choice B, bone density, while important in osteoporosis management, is not a specific concern related to initiating raloxifene therapy. Choice C, calcium levels, and choice D, blood pressure, are not directly related to the initiation of raloxifene therapy in a female client with osteoporosis.

Correct Answer: B

Rationale: The correct answer is to stop the transfusion (Choice B). The symptoms described - chills, headache, and low back pain - are indicative of a transfusion reaction. The priority action is to immediately stop the transfusion to prevent further complications such as more severe reactions like hemolytic reactions or anaphylaxis. Administering acetaminophen (Choice A) may help with symptoms but does not address the underlying cause. Slowing the transfusion rate (Choice C) may not be sufficient if a serious transfusion reaction is occurring. Administering antihistamines (Choice D) is not the priority in this situation; stopping the transfusion takes precedence to ensure patient safety.

Correct Answer: D

Rationale: A peer-reviewed nursing research article is the best resource for obtaining evidence-based information because it provides the most current and reliable data on nursing interventions. Choice A, the advice of an expert nephrology nurse, may be helpful but could be based on individual experience rather than the latest research. Retrospective chart reviews (Choice B) focus on past cases and may not reflect current best practices. Facility critical pathways (Choice C) offer standardized care plans but may not always incorporate the most up-to-date evidence-based practices.
