Correct Answer: B

Rationale: The correct answer is B: Fever. Fever in a postoperative client can indicate an infection, which is a serious complication and should be reported immediately to the provider for further evaluation and management. Clear lung sounds (Choice A) are a positive finding indicating normal respiratory function. Pain in the operative leg (Choice C) is expected postoperatively and should be managed with appropriate pain relief measures. Capillary refill of 2 seconds (Choice D) is within the normal range (less than 3 seconds) and is not a concerning finding postoperatively.

Correct Answer: C

Rationale: The correct answer is C: 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a beneficial technique for clients with COPD as it helps improve airflow by keeping the airways open longer. Choice A is incorrect as abdominal breathing may not be as effective in COPD as pursed-lip breathing. Choice B, inhaling quickly and deeply through the nose, is not recommended as it can lead to hyperventilation. Choice D, breathing quickly and deeply during exercise, is also not suitable for clients with COPD as it can cause increased shortness of breath.

Correct Answer: B

Rationale: The correct answer is B: 'What high school did you graduate from?' Remote memory involves recalling past events, such as educational history, making option B the most appropriate question to assess this aspect of memory in an older adult with mild dementia. Option A pertains to recent memory. Option C focuses on short-term memory. Option D addresses recent memory as well.

Correct Answer: D

Rationale: The correct answer is 'D: All of the above.' Edema, hypertension, and shortness of breath are key signs of fluid overload, particularly common in patients with heart failure. Edema refers to the swelling caused by excess fluid trapped in the body's tissues, hypertension can be a result of fluid volume overload, and shortness of breath can occur due to fluid accumulation in the lungs. Therefore, all these signs collectively indicate fluid overload in a patient. Choices A, B, and C are incorrect individually as each alone may not necessarily indicate fluid overload, but when seen together, they strongly suggest fluid volume excess in the body.

Correct Answer: A

Rationale: The most appropriate intervention for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures stability and helps distribute weight evenly between the legs, reducing the risk of falls. Using the cane on the weak side of the body (Choice B) may not provide adequate support. Advancing the cane and the strong leg simultaneously (Choice C) can lead to imbalance and increases the risk of falls. Advancing the cane too far with each step (Choice D) can also compromise balance and stability.
