Correct Answer: D

Rationale: The nurse should instruct parents to limit their child’s TV watching to 1 to 2 hours per day to prevent childhood obesity.

Correct Answer: B

Rationale: In the case of Marge, who exhibits selective eating habits and struggles with weight gain, providing high-calorie snacks and meals at the table throughout the day can be an effective intervention. This strategy can help increase her food intake in a structured environment, promoting healthier eating habits and potentially addressing her below-average weight status. By offering calorie-dense foods at designated meal times, Marge may be more likely to consume the necessary nutrients to support her growth and development, ultimately improving her overall health.

Correct Answer: D

Rationale: In hyperkalemia, cardiac arrhythmias are the most critical and life-threatening manifestation that requires immediate intervention. Hyperkalemia can lead to dangerous heart rhythm disturbances, potentially resulting in cardiac arrest. Prompt treatment is essential to stabilize the heart rhythm and prevent life-threatening complications.

Correct Answer: B

Rationale: If diuresis has not occurred with corticosteroids in nephrotic syndrome, a diuretic like Furosemide (Lasix) is the appropriate choice to promote diuresis. Furosemide works by increasing urine production and reducing fluid retention. While Ibuprofen is an anti-inflammatory agent, it does not directly induce diuresis. Ciprofloxacin is an antibiotic and is not indicated for promoting diuresis in this scenario. Cyclophosphamide is an immunosuppressant, not an antisuppressant, and is not typically used to induce diuresis in nephrotic syndrome.

Correct Answer: D

Rationale: Rheumatic fever can lead to cardiac complications, such as dysrhythmias. Therefore, it is essential for the nurse to monitor the child's heart rate closely for any signs of dysrhythmias. This will help in early identification and prompt management of potential cardiac issues associated with rheumatic fever.
