Correct Answer: B

Rationale: Using a regular blood pressure cuff on a morbidly obese client will lead to a falsely high blood pressure reading. This occurs because the cuff is not appropriately sized for the client's arm circumference, resulting in increased pressure on the artery and an inaccurate high reading. Choice A is incorrect because the reading will be falsely high, not low. Choice C is incorrect as the reading will not be accurate with an incorrectly sized cuff. Choice D is incorrect because the reading will be affected by using the wrong cuff size.

Correct Answer: A

Rationale: When a client with an indwelling catheter reports a need to urinate, the nurse's initial action should be to check the catheter for patency. This is crucial to ensure that the catheter is not blocked, twisted, or kinked, which could lead to urinary retention. Reassuring the client without assessing the catheter could delay necessary interventions. Re-catheterizing the bladder with a larger-gauge catheter should not be the first step unless catheter patency is confirmed as an issue. Collecting a urine specimen for analysis is important but not the immediate priority when the client reports a need to urinate.

Correct Answer: A

Rationale: The correct response is A: 'When the GI tract is working again, in about three to five days, the tube can be removed.' After a partial colectomy, the GI tract needs time to recover and start functioning properly. The NG tube is typically removed when peristalsis returns, indicating GI function restoration, which usually occurs within 3-5 days post-op. Choice B is incorrect because the removal of the NG tube is not solely based on nausea improvement. Choice C is incorrect as it provides a longer duration for tube removal than is usually necessary. Choice D is incorrect as the cessation of drainage alone does not dictate NG tube removal; the return of GI function is the primary indicator.

Correct Answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: A

Rationale: Discharge planning for a patient admitted to the neurological unit with a stroke diagnosis should begin at the time of admission. Initiating discharge planning early allows for a comprehensive assessment of the patient's needs, enables better coordination of care, and ensures a smooth transition from the hospital to the next level of care. Option B is incorrect because waiting until the day before discharge does not provide enough time for adequate planning. Option C is incorrect because waiting until outpatient therapy is no longer needed delays the planning process. Option D is incorrect because waiting until the discharge destination is known may result in rushed planning and inadequate preparation for the patient's needs.
