Correct Answer: A

Rationale: A glomerular filtration rate of 14 mL/minute indicates severe kidney dysfunction, necessitating hemodialysis. The other options, BUN of 16 mg/dL, serum magnesium of 1.8 mg/dL, and serum phosphorus of 4.0 mg/dL, are within normal ranges and do not serve as indications for hemodialysis.

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 D: Weight. Weight monitoring is essential to assess the effectiveness of desmopressin therapy, as fluid retention is a common side effect. Monitoring fasting blood glucose (choice A) is not directly related to desmopressin therapy for diabetes insipidus. Monitoring carbohydrate intake (choice B) may be important in diabetes management but is not specific to desmopressin therapy. Hematocrit (choice C) monitoring is not a primary concern when managing diabetes insipidus with desmopressin.

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.

Correct Answer: D

Rationale: The correct intervention for a client with a stage 3 pressure injury is to apply a moisture barrier ointment. This helps protect the skin, maintain moisture balance, and promote healing. Choice A is incorrect because povidone-iodine solution can be too harsh for wound care. Choice B is incorrect as hydrogen peroxide can be cytotoxic to healing tissue. Choice C is important for preventing pressure injuries but is not a direct intervention for a stage 3 wound.
