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.)

Answer and Explanation

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 A

Explanation

A. The father who had gastritis 2 weeks ago B. A neighbor's child who has chickenpox C. A sibling who had a sore throat 3 weeks ago D. A classmate who has fifth disease

Correct Answer is C

Explanation

A. Gastritis in the father is unrelated to rheumatic fever, which is linked to streptococcal infections, not gastrointestinal issues.

B. Chickenpox, caused by the varicella-zoster virus, is not related to rheumatic fever.

C. A sibling who had a sore throat 3 weeks ago is significant because rheumatic fever often follows an untreated or inadequately treated streptococcal throat infection. Recognizing a recent history of streptococcal infection is key to understanding the source of the child's rheumatic fever.

D. Fifth disease, caused by parvovirus B19, is also unrelated to rheumatic fever.
