A nurse is preparing to administer acetaminophen 15 mg/kg PO to a preschool child for fever. The child weighs 30 lb. Available is acetaminophen liquid 160 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.)
The Correct Answer is ["6.4"]
Convert the child's weight from pounds to kilograms:
Weight in pounds: 30 lb
Conversion: 1 lb ≈ 0.454 kg
Weight in kg: 30 lb× 0.454 kg/lb =13.62 kg
30lb×0.454kg/lb=13.62kg
Calculate the dose in mg:
Dose: 15 mg/kg
15 mg/kg ×13.62kg=204.3 mg
Determine the volume to administer:
Available concentration: 160 mg/5 mL
Volume in mL:
204.3 mg ÷160 mg/5 mL
= 204.3mg×5ml ÷160mg
=6.4mL
The nurse should administer 6.4 mL of acetaminophen.

Correct Answer is B
Explanation
A. "This will not be painful, just a little uncomfortable." While this statement might provide some reassurance, it does not actively engage the child or make the task of taking deep breaths more enjoyable.
B. "Let's play a game of blowing cotton balls across your table." This is the best choice as it makes deep breathing fun and engaging for the child, encouraging them to participate without feeling like it’s a chore.
C. "Do you want to take deep breaths for me now?" This approach is too passive and doesn't engage the child actively or make the activity interesting.
D. "You can't go to the playroom until you finish doing your deep breathing." This approach can create negative reinforcement and might make the child associate deep breathing with punishment or coercion, which is not desirable.
Correct Answer is A
Explanation
A. Assist with administering a blood transfusion. Blood transfusions are often necessary in sickle cell crisis to manage severe anemia and improve oxygen delivery to tissues. This action helps alleviate the symptoms of the crisis and prevent complications.
B. Withhold opioids to avoid dependence. Opioids are essential for managing the severe pain associated with sickle cell crises. Concerns about dependence should not prevent adequate pain management in an acute setting.
C. Encourage exercise. During a sickle cell crisis, rest is crucial to reduce oxygen demand and prevent further sickling of red blood cells. Exercise is contraindicated during a crisis.
D. Initiate a 2 L/day fluid restriction. Adequate hydration is critical in managing sickle cell crisis, as it helps prevent further sickling of cells. Fluid restriction is inappropriate and could worsen the condition.
