Correct Answer: B

Rationale: Assessing the reasons for refusal is crucial as it allows the healthcare professional to understand the patient's concerns, which can range from fear of side effects to cost issues. By identifying the underlying reasons, the healthcare professional can tailor their approach to address these specific concerns, potentially improving medication adherence. Giving the medication immediately (Choice A) without understanding the patient's reasons for refusal can lead to further non-compliance. While documenting refusal (Choice C) is important for legal and tracking purposes, it does not directly address the patient's concerns. Exploring alternative treatment options (Choice D) may be considered after understanding the reasons for refusal, but it is not the initial step in managing medication refusal.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for anaphylactic shock as it helps reverse the severe allergic reaction by constricting blood vessels, increasing heart rate, and opening airways for improved breathing. Oxygen (Choice B) can be administered after epinephrine to support oxygenation. Corticosteroids (Choice C) may be used to prevent a biphasic reaction but are not the initial intervention. Antihistamines (Choice D) can help with itching and hives but do not address the life-threatening symptoms of anaphylaxis.

Correct Answer: B

Rationale: The correct answer is to inject the medication into the lateral abdominal wall when administering enoxaparin. This is the recommended technique to ensure proper absorption and prevent tissue damage. Choice A is incorrect because enoxaparin should be administered subcutaneously, not intramuscularly. Choice C is incorrect as massaging the injection site after administration is not recommended, as it can cause bruising and discomfort. Choice D is incorrect because the prefilled syringe should not be discarded after expelling the air bubble; it should be used for the injection.

Correct Answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

Correct Answer: C

Rationale: The correct answer is C. Doxazosin can cause orthostatic hypotension, leading to dizziness and falls if the client rises quickly from a seated position. Instructing the client to rise slowly when sitting up from bed helps prevent these adverse effects. Choices A, B, and D are incorrect because doxazosin does not directly relate to caloric intake, dietary fiber, or a specific time of day for administration.
