Correct Answer: A

Rationale: Corrected Rationale: Applying heat to inflamed joints can help relieve pain in clients with osteoarthritis. Heat therapy can help improve blood circulation, relax muscles, and reduce stiffness. Choice B, providing passive range-of-motion exercises, may be beneficial for joint mobility but is not the first-line intervention for pain relief in osteoarthritis. Choice C, encouraging prolonged use of NSAIDs, should be done cautiously due to potential side effects and should be guided by a healthcare provider. Choice D, applying cold packs to the joints, is not recommended for osteoarthritis as cold therapy can worsen stiffness and discomfort in this condition.

Correct Answer: B

Rationale: Maintaining the chest tube drainage system below the client's chest level is crucial to ensure proper drainage and prevent complications. Clamping the chest tube can lead to a tension pneumothorax, stripping the chest tube is an outdated practice that can cause damage to the tissues, and keeping the collection device at the level of the client's chest can impede proper drainage and lead to fluid accumulation.

Correct Answer: A

Rationale: The correct answer is to confirm the client's perception of the event. In crisis intervention, understanding the client's perspective is crucial as it helps the nurse assess the situation accurately and provide tailored support. This step can also help build rapport and trust with the client. Option B, notifying the client's support system, may be important but should come after assessing the client's perception. Option C, helping the client identify personal strengths, and option D, teaching relaxation techniques, are valuable interventions but should follow the initial step of confirming the client's perception.

Correct Answer: C

Rationale: The correct answer is C. A fundus that is deviated to the right may indicate a full bladder, which should be addressed postpartum. Choice A is incorrect because red lochia with small clots is expected during the early postpartum period. Choice B is incorrect as the fundus should be firm and midline, not at the umbilicus. Choice D is incorrect as perineal pain and swelling are common postpartum findings that do not require immediate reporting to the provider.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration in clients receiving enteral feedings is to elevate the head of the bed during feedings. This position helps prevent regurgitation and aspiration of the feeding. Positioning the client supine (Choice A) increases the risk of aspiration as it promotes reflux. Administering feedings over 10 minutes (Choice B) does not directly reduce the risk of aspiration. Placing the client in a lateral position after feedings (Choice D) does not address the risk of aspiration during the feeding process.
