Correct Answer: A

Rationale: The correct answer is A. Lower anchors and tethers, known as the LATCH child safety seat system, should be used to secure an infant's car seat in the vehicle. This system provides a safer and more secure way of installing the car seat compared to using the seat belt alone. Using the lower anchors and tethers ensures proper installation and reduces the risk of car seat movement during travel, providing optimal protection for the infant.

Correct Answer: C

Rationale: The nurse should inform the parent that the child will need pulmonary function tests every 12 to 24 months to assess lung function and response to treatment. These tests help evaluate the presence of lung disease, monitor disease progression, and assess the effectiveness of the current therapeutic regimen in managing asthma.

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: 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: B

Rationale: When a patient is already receiving glucocorticoids for rheumatoid arthritis and complains of a headache, it is essential to consider the potential interactions and side effects of additional medications. Aspirin and NSAIDs like ibuprofen and naproxen sodium can increase the risk of gastrointestinal irritation and ulceration when used concurrently with glucocorticoids. Acetaminophen is a safer choice in this scenario for managing the patient's headache without exacerbating the gastrointestinal issues associated with the use of glucocorticoids.
