Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A: Oxygen saturation above 90%. This is a discharge criterion because adequate oxygen saturation indicates the patient is breathing well and there is no immediate respiratory compromise. Oxygen saturation below 90% (choice C) would indicate hypoxemia and would not be safe for discharge. IV narcotics given less than 15 minutes ago (choice B) can still be in effect and may impair the patient's ability to function post-surgery. IV narcotics given less than 30 minutes ago (choice D) is a longer timeframe but still not ideal for discharge as the effects of the narcotics may not have fully worn off.

Correct Answer: D

Rationale: The correct answer is D because airborne pollens and molds are common triggers for allergic rhinitis. Understanding these triggers helps in avoiding exposure and managing symptoms. Choices A, B, and C are incorrect as they do not specifically relate to allergic rhinitis triggers, focusing instead on other forms of medication or topical applications. By understanding airborne triggers, the patient can take appropriate preventive measures.

Correct Answer: C

Rationale: The correct answer is C. Wearing protective gear such as gown, mask, gloves, and goggles when entering the room is crucial to prevent infection in patients with AIDS. This intervention helps to minimize the risk of transmitting pathogens to the patient and vice versa. The protective gear acts as a barrier to prevent the spread of infectious agents. It also protects healthcare workers from exposure to potentially harmful pathogens. Prohibiting visitors who are severely immunodeficient (choice A) may be isolating for the patient and does not directly address preventing infection transmission. Prohibiting visitors with a cough (choice B) is important but does not cover all potential sources of infection. Ensuring protective barrier isolation precautions are in place (choice D) is a general statement and does not specify the practical steps needed to prevent infection transmission effectively.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Statement C indicates a misunderstanding that medication can be stopped when feeling better, which is incorrect. 2. Hypertension is a chronic condition that often requires lifelong medication. 3. This demonstrates a lack of understanding regarding the necessity of long-term management. 4. Statements A, B, and D show knowledge about hypertension's effects, dietary management, and awareness, respectively. Summary: Statement C is incorrect as it suggests stopping medication, while statements A, B, and D show accurate understanding of hypertension.

Correct Answer: B

Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.
