Correct Answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

Correct Answer: C

Rationale: The correct intervention for a client with Alzheimer's disease who demonstrates confusion and wandering behavior is to ensure that the client wears an identification bracelet at all times. This helps prevent wandering and ensures the client's safety. Placing the client in a well-lit area may be beneficial for orientation but does not directly address wandering behavior. Using physical restraints is not recommended as it can lead to agitation and other complications. Keeping the client's bed in the lowest position is important for fall prevention but does not specifically address the issue of wandering behavior.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid lying down after meals.' This instruction is important for clients with GERD to prevent acid reflux. Lying down after meals can worsen GERD symptoms by allowing stomach acid to flow back into the esophagus. Choices A, C, and D are incorrect. Choice A is incorrect because lying flat after meals can increase the risk of acid reflux. Choice C is incorrect because hot liquids may aggravate GERD symptoms. Choice D is incorrect because consuming a high-carbohydrate snack at bedtime can also trigger acid reflux in individuals with GERD.

Correct Answer: C

Rationale: The correct answer is C because bending at the hips can dislocate the hip joint in clients who have had a total hip arthroplasty. This movement should be avoided to prevent complications post-surgery. Choices A, B, and D are all correct statements for a client who has had a total hip arthroplasty. Avoiding prolonged sitting, crossing legs, and using a raised toilet seat are all appropriate measures to ensure proper healing and prevent complications.

Correct Answer: C

Rationale: The correct intervention for a client with dementia who is frequently agitated is to use a calm and reassuring approach when speaking to them. This approach helps reduce agitation and create a more therapeutic environment. Offering several choices may overwhelm the client and increase agitation, making choice A incorrect. Confronting the client can escalate the situation and worsen agitation, making choice B inappropriate. While encouraging stimulating activities is beneficial, it may not be the most effective intervention for immediate agitation management, making choice D less priority compared to using a calm and reassuring approach.
