Correct Answer: C

Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.

Correct Answer: A

Rationale: Corrected Rationale: In clients with cirrhosis, elevated ammonia levels can lead to hepatic encephalopathy, which is a serious complication. Monitoring ammonia levels is crucial to assess for changes in mental status and initiate treatment if needed. White blood cell count (choice B) is not the most important parameter to monitor in this scenario as it does not directly relate to the complications of cirrhosis. Albumin level (choice C) and hemoglobin level (choice D) are also important in cirrhosis, but in this case, monitoring ammonia level takes precedence due to its direct association with hepatic encephalopathy.

Correct Answer: C

Rationale: In sepsis with multi-organ failure, monitoring intake and output is critical to assess renal function and fluid balance, as organ failure can cause fluid shifts and decreased kidney function. Antibiotics are essential to treat the infection, but monitoring intake and output provides real-time insight into the client's status, helping to detect early signs of worsening organ function. Early ambulation and blood glucose monitoring are important aspects of care but are not as crucial as maintaining strict intake and output in this situation.

Correct Answer: B

Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.

Correct Answer: C

Rationale: Diuretics must be continued as long as the fluid problem persists to prevent heart failure symptoms.
