Correct Answer: C

Rationale: In a postoperative client, a urine output of 30 mL/hr is a concerning finding as it indicates oliguria, which may suggest dehydration or kidney impairment. Adequate urine output is essential for monitoring renal function and overall fluid status. A heart rate of 78/min is within the normal range for an adult. An oxygen saturation of 95% is acceptable and indicates adequate oxygenation. Serosanguineous wound drainage is expected in the early postoperative period and is not a cause for immediate concern unless it becomes excessive or changes character.

Correct Answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

Correct Answer: A

Rationale: The correct answer is to 'Check daily weight.' Monitoring daily weight is the most accurate method to assess for fluid overload in patients with heart failure. Weight gain can indicate fluid retention, a common issue in heart failure patients. Checking blood pressure (Choice B) can provide information about hemodynamic status but may not be as specific for fluid overload as monitoring weight. Monitoring heart sounds (Choice C) can provide information about cardiac function but may not directly assess fluid overload. Assessing for jugular vein distention (Choice D) can be a sign of increased central venous pressure but may not always correlate with fluid overload as accurately as daily weight checks.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with COPD is to encourage the client to increase physical activity. Increased physical activity helps manage COPD symptoms by improving lung function and preventing deconditioning. Placing the client in the Trendelenburg position is not recommended for COPD as it can worsen breathing difficulties. Limiting fluid intake to prevent fluid overload is not typically necessary in COPD unless the client has comorbid conditions that require fluid restriction. Administering high-flow oxygen via mask may be necessary for COPD clients with severe hypoxemia, but it is not the initial action for planning care.
