Fundamentals of Nursing HESI

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

Correct Answer: A

Rationale: The nurse would most likely suspect fungi as the cause of thickened and separated toenails. Fungal infections can lead to changes in the nail structure, causing them to thicken and separate from the nail bed. Friction, nail polish, and nail polish remover are less likely to cause these specific nail changes. Friction typically leads to calluses or blisters, while nail polish and nail polish remover do not commonly result in thickened and separated toenails.

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: 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.

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.
