A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb.
The amount available is acetaminophen 120 mg/5 mL.
How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Step 1 is to convert the child's weight from pounds to kilograms: 28 lb ÷ 2.2 lb/kg = 12.727 kg.
Step 2 is to calculate the dose: 10 mg/kg × 12.727 kg = 127.27 mg.
Step 3 is to determine how many mL is needed: 127.27 mg ÷ (120 mg/5 mL) = 5.3029 mL.
Step 4 is to round to the nearest tenth: 5.3 mL. Final answer: 5.3 mL

Correct Answer is C
Explanation
Choice A rationale
Playing might cause irregular breathing patterns due to excitement or activity, making it hard to get an accurate respiratory rate.
Choice B rationale
Crying can alter the normal breathing rate and pattern, resulting in an inaccurate assessment of respirations.
Choice C rationale
Sleeping provides the most accurate assessment of respirations, as the infant’s breathing will be at its natural, resting rate.
Choice D rationale
Laughing, similar to crying, causes irregular breathing patterns due to physical exertion and emotions, affecting accuracy.
