Extract:
Question 1 of 5
The nurse is caring for the child who has a virulent infection. The HCP prescribes cefazolin sodium IV 50 mg every 6 hours. The Pediatric Dosage Handbook states the safe range of cefazolin is 6.25 to 25 mg per kg per day. The child weighs 18 lb. What is the most appropriate action by the nurse?
Correct Answer: C
Rationale: Convert 18 lb to kg: 18 ÷ 2.2 = 8.18 kg. Safe range: 6.25–25 mg/kg/day = 51.13–204.5 mg/day. Prescribed dose: 50 mg × 4 = 200 mg/day, which is within the safe range.
Question 2 of 5
The nurse is caring for the 5-year-old with rubeola. Which intervention by the nurse best ensures the child's comfort?
Correct Answer: A
Rationale: Rubeola (measles) causes photophobia; dimming lights reduces discomfort. Baby oil baths, warm mist tents, and decongestants do not address primary symptoms.
Question 3 of 5
Lithium carbonate is ordered for a client with overactive behavior. The nurse should observe the client for which of these side effects?
