ATI Nurs 243 Pediatrics Exam Questions

Extract:

An infant weighing 5kg, prescribed digoxin 4mcg/kg/day, safe dose 3.4 to 5.1 mcg/kg/day, label 0.25 mg/5mL.


Question 1 of 5

The nurse is preparing to administer the daily maintenance dose of digoxin to an infant: Infant's Weight: 5kg Order: Administer 4mcg/kg/day Safe Dose: 3.4 to 5.1 mcg/kg/day Label: 0.25 mg/5mL

Correct Answer: 0.4 mL

Rationale:
Step 1: Calculate the infant's daily maintenance dose of digoxin: 5kg x 4mcg/kg/day = 20mcg/day.

Step 2: Check if the calculated dose falls within the safe dose range of 3.4 to 5.1 mcg/kg/day - 20mcg/day is within the range.

Step 3: Convert the ordered dose from 20mcg to mg (1mg = 1000mcg) = 0.02mg.

Step 4: Calculate the volume needed using the label concentration (0.25mg/5mL). 0.02mg / 0.25mg = 0.08 mL.

Step 5: Verify that 0.08 mL is within the safe dose volume range of 0.068 to 0.102 mL.

Step 6: Round the calculated volume to the nearest appropriate measurement, which is 0.4 mL.
