Nclex Questions Management of Care

1. What is the term for the tendency of a drug to combine with its receptor?

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

2. The LPN is caring for a client with an NG tube, and the RN administers evening medications through the NG tube. The client asks if he can lie down when the nurse leaves the room. What is the most appropriate response?

Correct answer: A

Rationale: After administering medication through an NG tube, the client should remain upright for 30 minutes to ensure proper absorption of the medications. Therefore, the most appropriate response is to advise the client to lie down in 1 hour. Choice B is incorrect because waiting only 30 minutes may not provide sufficient time for the medications to be fully absorbed, as the recommended time is 30 minutes. Choice C is misleading as it incorrectly suggests that lying down in about 30 minutes is acceptable, which could compromise medication effectiveness. Choice D is incorrect as it does not provide accurate information regarding the appropriate timing for lying down after NG tube medication administration, potentially leading to decreased medication absorption.

3. Which of the following is true of advanced directives?

Correct answer: A

Rationale: The correct answer is that advanced directives should be appropriately documented in the client's chart. Advanced directives are legal requests regarding a client's healthcare that come into effect under specific circumstances, regardless of the severity of their illness or level of consciousness. Choice B is incorrect because advanced directives can cover various healthcare decisions, not just terminal illnesses. Choice C is incorrect as advanced directives can be established and documented while the client is conscious, not only if they are unconscious. Choice D is incorrect because advanced directives are indeed legal requests, not non-legal requests.

4. A case manager is reviewing notations made in clients' records. Which note indicates an unexpected outcome and the need for immediate follow-up?

Correct answer: A

Rationale: A case manager is responsible for coordinating a client's care and monitoring for unexpected outcomes. The situation that indicates an unexpected outcome and the need for immediate follow-up is when a client exhibits signs of increased intracranial pressure after a craniotomy. This indicates a deteriorating condition that requires urgent intervention. Choices B, C, and D describe expected outcomes or normal findings related to specific conditions, which do not demand immediate follow-up.

5. While assisting a healthcare provider in assessing a hospitalized client, the healthcare provider is paged to report to the recovery room. The healthcare provider instructs the nurse verbally to change the solution and rate of the intravenous (IV) fluid being administered. What is the most appropriate nursing action in this situation?

Correct answer: B

Rationale: Verbal prescriptions should be avoided due to the risk of errors. If a verbal prescription is necessary, it should be promptly written and signed by the healthcare provider, typically within 24 hours. Following agency policies and procedures regarding verbal prescriptions is crucial. In this scenario, the most appropriate nursing action is to request the healthcare provider to document the prescription in the client's record before leaving the unit. Calling the nursing supervisor to accept the verbal prescription without documentation, telling the healthcare provider to delay treatment until documented, and directly changing the IV fluid based on verbal orders all pose risks and do not align with best practices in medication administration.
