Correct Answer: D

Rationale: The correct answer is D, the serum ammonia level of 180 mcg/dL. An elevated serum ammonia level indicates hepatic dysfunction and can lead to hepatic encephalopathy, which is a medical emergency requiring immediate intervention. Options A, B, and C are within normal ranges or slightly abnormal values for clients with cirrhosis and do not pose an immediate threat. Serum albumin levels may indicate malnutrition, prothrombin time may reflect liver synthetic function, and hemoglobin levels can be affected by various factors but do not require immediate intervention in this scenario.

Correct Answer: D

Rationale: In this scenario, the correct action is to apply a water-soluble lubricant to the lips, oral mucosa, and nares. This helps in keeping the mucous membranes moist, which is essential for a client with a dry mouth due to the nasogastric tube and oxygen therapy. Choice A, applying a petroleum-based lubricant to the lips, is not suitable as it may not be safe for internal use. Choice B, giving sips of water, is contraindicated as the client has a nasogastric tube in place for suction. Choice C, providing ice chips, is also not recommended as the client needs proper lubrication to address dryness, not cold stimulation.

Correct Answer: D

Rationale: Malnourished individuals are at higher risk of severe complications from cold exposure due to their weakened immune system and decreased ability to regulate body temperature. This places them at a greater risk of hypothermia and other cold-related conditions, making them the most vulnerable group in need of shelter. Choice A is not the most critical as the injury is from 3 weeks ago and should have received appropriate medical care by now. Choice B, a young person with diabetes mellitus, while vulnerable, can manage their condition with proper medication and care. Choice C, a middle-aged person with hypertension, may need monitoring but is less susceptible to immediate harm from cold exposure compared to a malnourished individual.

Correct Answer: C

Rationale: The correct action for the nurse to take first after an elderly client with disabilities slips and falls is to check the client for lacerations or fractures. This is crucial to assess the extent of injuries and provide appropriate medical attention promptly. Option A, providing orange juice, is not a priority in this situation and does not address the potential injuries. While calling 911 (Option B) may be necessary, assessing for immediate injuries takes precedence. Assessing the client's blood sugar level (Option D) is not the immediate priority after a fall unless there is a specific indication or suspicion of hypoglycemia.

Correct Answer: D

Rationale: A productive cough with pink, frothy sputum is a classic sign of pulmonary edema, indicating fluid in the lungs. This finding requires immediate intervention to prevent respiratory compromise and worsening of the condition. Peripheral edema (Choice A) is a manifestation of heart failure but is not as urgent as addressing pulmonary edema. Oxygen saturation of 88% (Choice B) is low and requires attention, but the pink, frothy sputum signifies acute respiratory distress. Jugular vein distention (Choice C) can be seen in heart failure, but the immediate concern in this scenario is addressing the pulmonary edema to ensure adequate gas exchange and oxygenation.
