Correct Answer: A

Rationale: An elevated BUN level indicates possible nephrotoxicity, which is a side effect of gentamicin and should be reported. Elevated serum creatinine and WBC count are not specifically related to gentamicin therapy. Normal serum glucose levels are also within the expected range.

Correct Answer: C

Rationale: The correct answer is C: 'Use a Z-track technique to administer the injection.' When administering IM injections, using a Z-track technique helps prevent medication from leaking into subcutaneous tissues. This technique involves pulling the skin laterally, injecting the medication deeply into the muscle, and then releasing the skin. Choice A is incorrect because massaging the injection site after administering the medication can lead to increased blood flow and potential leakage of the medication. Choice B is incorrect as the needle should typically be inserted at a 90° angle for IM injections to ensure proper delivery into the muscle. Choice D is incorrect as aspirating for blood before injecting the medication is not routinely recommended for IM injections.

Correct Answer: A

Rationale: The correct answer is A. Sucralfate is most effective when taken 1 hour before meals to protect the stomach lining. Option B is incorrect because sucralfate should not be taken after meals. Option C is incorrect because sucralfate is typically taken on a regular schedule, not just when symptoms occur. Option D is incorrect because sucralfate should not be taken with milk, as it can interfere with its effectiveness.

Correct Answer: D

Rationale: Administering a rectal suppository 30 minutes before scheduled defecation times is essential in a bowel-training program following a spinal cord injury. The suppository helps stimulate bowel movements and aids in establishing a regular bowel routine. Encouraging a maximum fluid intake of 1,500 ml per day (Choice A) might be beneficial for bowel function, but it is not specific to the bowel-training program. Increasing the intake of refined grains in the diet (Choice B) is not necessary and could potentially lead to constipation rather than improving bowel movements. Providing a cold drink prior to defecation (Choice C) may not directly contribute to the effectiveness of the bowel-training program compared to the use of a rectal suppository.

Correct Answer: D

Rationale: Facial weakness is a common finding in clients with Guillain-Barr© syndrome due to muscle weakness. While increased urine output is not typically associated with Guillain-Barr© syndrome, hyperactive reflexes are more indicative of conditions like hyperthyroidism or spinal cord injury. Hypoactive bowel sounds are not a classic finding in Guillain-Barr© syndrome, making it an incorrect choice.
