Correct Answer: C

Rationale: The correct answer is to dim the lighting in the client's room. Dim lighting can help reduce confusion and agitation in clients with Alzheimer's disease. Placing the client in seclusion (Choice A) is not recommended as it can lead to feelings of isolation and distress. Requesting PRN restraints (Choice B) should be avoided in clients with Alzheimer's as it can increase agitation and pose safety risks. Leaving one side rail up on the client's bed (Choice D) may not directly address the client's confusion and wandering behavior.

Correct Answer: B

Rationale: The correct intervention for a client with pneumonia is to perform chest percussion every 4 hours. Chest percussion helps loosen secretions and improve airway clearance in clients with pneumonia. Placing the client in the supine position can worsen breathing, so it is incorrect. Administering oxygen via nasal cannula is a common intervention for clients with respiratory issues but is not specific to pneumonia. Limiting fluid intake to 1,500 mL/day may not be appropriate as pneumonia can lead to dehydration, so it is not the priority intervention.

Correct Answer: A

Rationale: Administering oxygen is the best initial nursing intervention for a patient with suspected pulmonary embolism because it helps address hypoxia, a common complication of this condition. Oxygen therapy can improve oxygenation and support vital organ function. Administering anticoagulants (Choice B) is a treatment option for confirmed pulmonary embolism but not the initial intervention. Repositioning the patient (Choice C) and checking oxygen saturation (Choice D) are important assessments but do not address the immediate need to improve oxygenation in a patient with suspected pulmonary embolism.

Correct Answer: A

Rationale: The best dietary recommendation for a patient with chronic liver disease is a low protein diet. In liver disease, the liver may have difficulty processing protein, leading to the accumulation of toxins like ammonia in the body. A low protein diet helps reduce the burden on the liver and minimizes the production of these harmful substances. High protein diets can exacerbate the condition by increasing the workload on the liver. A low sodium diet (Choice C) is also important for liver disease patients as excess sodium can contribute to fluid retention and swelling, but reducing protein intake is the primary focus in these cases.

Correct Answer: D

Rationale: The correct answer is to recheck blood sugar levels in 15 minutes. This intervention is crucial to ensure that the hypoglycemia has been effectively corrected after the initial treatment. Administering IV fluids may be necessary in cases of severe dehydration but is not the primary intervention for hypoglycemia. Checking blood sugar levels is important, but the primary intervention should focus on treating the low blood sugar levels first, which is done by providing oral glucose. However, the most critical step after providing initial treatment is to recheck blood sugar levels to confirm that they have improved to safe levels.
