A nurse is preparing to administer digoxin 12 mcg/kg/day PO to divide equally every 12 hr to a school-age child who weighs 66 lb. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3.6"]
To calculate the dosage of digoxin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 66 pounds, which is approximately 30 kilograms (66 ÷ 2.2). The prescribed dose is 12 micrograms per kilogram per day, which equals 360 micrograms per day (12 mcg × 30 kg). Since the dose is divided every 12 hours, the child should receive 180 micrograms every 12 hours. The digoxin elixir is available at a concentration of 0.05 mg/mL, which is the same as 50 micrograms per milliliter. To find out how many milliliters to administer per dose, divide the dose in micrograms by the concentration: 180 mcg ÷ 50 mcg/mL equals 3.6 mL.

Correct Answer is B
Explanation
A. Telling the child that temper tantrums are unacceptable may not be effective, as toddlers may not fully understand this concept.
B. Ignoring temper tantrums is often recommended because giving attention to the tantrum can reinforce the behavior. Consistently ignoring the tantrum can help decrease their frequency over time.
C. While distraction can sometimes be effective, it may not work in the middle of a tantrum when the child is already upset.
D. Physically restraining the child is not recommended as it can escalate the situation and lead to further distress.
Correct Answer is ["4"]
Explanation
To calculate the flow rate in gtt/min, the nurse should use the formula: (Volume in mL * Drop factor) / Time in minutes. In this case, the prescribed volume is 150 mL/hr. Since there are 60 minutes in an hour, the time for the infusion is 12 hours * 60 minutes/hour = 720 minutes. The drop factor is 20 gtt/mL. Plugging these values into the formula gives: (150 mL * 20 gtt/mL) / 720 minutes = 3000 gtt / 720 minutes = 4.1666 gtt/min. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 4 gtt/min.
