Correct Answer: A

Rationale: After identifying a problem in a client, the next step for the LPN/LVN is to determine the etiology or cause of the problem. Understanding the root cause of the issue is essential as it guides the development of appropriate interventions. Option B, prioritizing nursing care interventions, is premature without knowing the cause of the problem. Option C, planning appropriate interventions, also relies on knowing the etiology first to ensure the interventions directly address the underlying issue. Collaborating with the client to set goals, as mentioned in option D, is important but typically comes after understanding the cause of the problem to ensure the goals are relevant and effective.

Correct Answer: B

Rationale: The correct instruction for using a metered-dose inhaler is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to be absorbed more effectively in the lungs. Inhaling quickly and deeply while pressing down on the inhaler (Choice A) may cause the medication to deposit in the mouth and throat rather than reaching the lungs. Exhaling immediately after inhaling the medication (Choice C) may also lead to medication wastage. Shaking the inhaler before each use (Choice D) is not necessary for all types of inhalers and can sometimes cause improper drug delivery.

Correct Answer: B

Rationale: The correct response is 'It is very upsetting to see an adult client regress.' In this situation, the nurse should acknowledge the emotional impact of caregiving on the assistive personnel and address it professionally. Choice A is incorrect because reporting to the supervisor may not directly address the emotional concerns raised. Choice C is incorrect because immediately resorting to diapers without further assessment or intervention is not the most appropriate solution. Choice D is incorrect as the client's well-being and care are a shared responsibility among healthcare team members.

Correct Answer: A

Rationale: To prevent complications associated with prolonged bed rest, encouraging the client to perform antiembolic exercises every 2 hours is essential. These exercises help promote circulation and prevent blood clots. Instructing the client to cough and deep breathe every 4 hours is beneficial for respiratory function, but it is not as critical as antiembolic exercises. Repositioning the client every 4 hours helps prevent pressure ulcers and maintain skin integrity. Restricting fluid intake is not recommended, as hydration is important for overall health and well-being, especially for clients on bed rest.
