Correct Answer: A

Rationale: Performing range-of-motion exercises is beneficial in reducing contractures around joints, maintaining joint mobility, and preventing stiffness in immobile clients. This intervention helps preserve muscle strength and joint function. Options B, C, and D are incorrect because: Option B suggesting decreasing fluid intake to prevent diarrhea is not relevant to preventing complications of immobility and could lead to dehydration; Option C, massaging the client's legs to reduce embolism occurrence, is not a recommended practice as massage can dislodge blood clots and increase the risk of embolism; Option D, turning the client from side to back every shift, is not sufficient as it does not address the need for maintaining joint mobility and preventing contractures in immobile clients.

Correct Answer: B

Rationale: To ensure optimal benefits from a metered-dose inhaler, the client should be instructed to compress the inhaler while slowly breathing in through the mouth. This technique facilitates the medication to reach deep into the lungs, allowing for an optimal bronchodilation effect. Option B is correct as it promotes the proper coordination of inhaler compression and inhalation, ensuring effective drug delivery. Options A, C, and D are incorrect as they do not support deep lung penetration of the medication, which is essential for its effectiveness in treating respiratory conditions.

Correct Answer: C

Rationale: The correct document the nurse should use to develop the unit's nursing guidelines for the mental health services department is ANA's Scope and Standards of Nursing Practice. This document specifically outlines the philosophy and standards of nursing practice, including psychiatric nursing. Option A, the Americans with Disabilities Act of 1990, and option D, the Patient's Bill of Rights of 1990, focus on client rights and legal protections rather than nursing practice guidelines. Option B, the ANA Code of Ethics with Interpretive Statements, provides ethical guidelines for nursing practice but does not specifically address the development of nursing guidelines for a mental health services department.

Correct Answer: D

Rationale: The best method for the nurse to evaluate the client's ability to perform a dressing change at home is by observing the client change the dressing unassisted. Direct observation allows the nurse to assess if the client has mastered the skill and provides an opportunity to confirm the proficiency. Options A, B, and C do not offer the same level of assessment as direct observation. Option A incorrectly focuses on the client's feelings rather than their actual performance ability. Option B, asking the client to demonstrate the procedure, may not accurately reflect their practical skills. Option C, seeking a family member's opinion, introduces potential bias and may not provide an accurate assessment of the client's ability to perform the dressing change independently.

Correct Answer: B

Rationale: When a nurse assesses a slowed IV rate by gravity with a healthy venous access site in a 2-year-old admitted for dehydration, the next step would be to check for kinks in the tubing and raise the IV pole. This action ensures that the IV fluid can flow freely and reach the patient at the correct rate. Applying a warm compress proximal to the site (Choice A) is not indicated in this situation as it does not address the underlying issue of a slowed IV rate due to mechanical factors. Adjusting the tape that stabilizes the needle (Choice C) or changing the IV solution bag (Choice D) are not the priority actions in this case. These choices do not address the issue of a slowed IV rate caused by kinks in the tubing or the height of the IV pole, which are more likely reasons for the problem observed.
