A child with a heart defect is placed on a maintenance dose of Lanoxin elixir. The ordered dose is 0.07mg/kg/day in 2 divided doses. The child weighs 19 pounds. What is the maximum amount of medication that will be given per dose by the nurse?
The Correct Answer is ["0.3"]
Convert weight from pounds to kilograms:
19pounds÷2.2=8.64kg
Calculate the total daily dose:
0.07mg/kg/day×8.64kg=0.6048mg/day
Divide the daily dose into two doses:
0.6048mg/day÷2=0.3024mg/dose
Round off the dose to two decimal places:
0.3024mg≈0.30mg
The maximum amount of medication per dose is 0.3 mg.

Correct Answer is A
Explanation
A. Administer parenteral antibiotics. The primary concern with premature rupture of membranes (PROM) is the risk of infection, so administering antibiotics is crucial to prevent infection in both the mother and fetus.
B. Prepare for delivery. Without signs of labor, the focus is on preventing infection and monitoring, not immediate delivery.
C. Provide emotional support. While important, the priority intervention is preventing infection.
D. Assess cervical dilation every 6 hours. Routine cervical checks are not typically necessary unless there are signs of labor or other indications.
Correct Answer is ["D","E","F"]
Explanation
