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","C","E"]
Explanation
A. I'll expect the plastic ring to fall off by itself within a week. This is correct; the Plastibell ring typically falls off within 5-8 days.
B. I'll apply petroleum jelly to his penis with diaper changes. Incorrect for Plastibell, because the plastic ring itself protects the site, and petroleum jelly can interfere with healing.
C. I'll make sure his diaper is loose in the front. This helps avoid pressure and irritation on the circumcised area.
D. I'll wash his penis with warm water and mild soap each day. Incorrect; the area should be kept clean but only water should be used to avoid irritation.
E. I'll call the doctor if I see any bleeding. Any significant bleeding should be reported to the healthcare provider immediately.
Correct Answer is B
Explanation
A. The newborn with a heart rate of 154 beats/minute. This is within the normal range for a newborn, which is between 120-160 beats per minute.
B. The newborn with a respiratory rate of 72 breaths/minute. This is abnormal; the normal respiratory rate for a newborn is between 30-60 breaths per minute. A rate of 72 could indicate respiratory distress and requires prompt evaluation.
C. The newborn with a red raised capillary hemangioma on the left forearm. Capillary hemangiomas are common, benign vascular tumors that typically do not require immediate intervention.
D. The newborn with whitish, hardened nodules on the gums of the mouth. These are likely Epstein pearls, which are harmless cysts often seen in newborns and typically resolve on their own.
