Correct Answer: B

Rationale: The correct teaching for a client prescribed metformin includes monitoring renal function regularly due to the risk of lactic acidosis, especially in clients with impaired kidney function. While taking metformin with meals can reduce gastrointestinal upset, it is not the highest priority teaching point. Avoiding alcohol is generally recommended but not the most critical teaching point in this scenario. Checking blood glucose levels regularly is important for diabetes management but not specifically related to metformin use.

Correct Answer: D

Rationale: The correct answer is D: Level of consciousness. When managing hepatic encephalopathy with lactulose, monitoring the client's level of consciousness is crucial as it is a key indicator of the therapeutic response to lactulose in reducing ammonia levels. Changes in consciousness can reflect the effectiveness of treatment and the progression of hepatic encephalopathy. Option A, percussion of the abdomen, is not directly related to evaluating the response to lactulose. Option B, blood glucose level, is important but not the priority in this context. Option C, serum electrolytes, while significant in liver disease, do not directly assess the impact of lactulose therapy on hepatic encephalopathy.

Correct Answer: C

Rationale: When a pediatric client is taking propranolol, the nurse should instruct the parents to report signs of overdose, including bradycardia. Propranolol is a beta-blocker that can lead to dangerously slow heart rate as a sign of overdose. While increased respiratory rate, seizures, and irritability may occur in some cases, bradycardia is the most critical symptom indicating an overdose of this medication.

Correct Answer: B

Rationale: Engaging in regular physical activity is a crucial lifestyle modification for managing hypertension. Regular exercise helps improve cardiovascular health, lower blood pressure, and contribute to overall well-being. Choices A, C, and D are incorrect. Increasing sodium intake is not recommended for hypertension as it can worsen fluid retention and elevate blood pressure. Increasing caffeine intake is also not advised as it may lead to increased heart rate and blood pressure. Reducing potassium intake is not beneficial as potassium is essential for maintaining healthy blood pressure levels.

Correct Answer: C

Rationale: All of the above findings should be reported to the healthcare provider for prompt evaluation and treatment. Swollen lymph nodes in the groin indicate regional lymphatic involvement, a core body temperature of 100.5°F suggests a mild fever response, and an elevated white blood cell count indicates an ongoing infection process. These findings collectively point towards the spread of infection and require immediate attention to prevent further complications.
