Order: Aminophyllin 25 mg PO q8h
Recommended: 3-6 mg/kg/day in divided doses q 8h
Child's Weight: 35 pounds
Available: Aminophyllin 125 mg/5ml
What is the recommended range for this child for a single dose?
15.9 mg to 31.8 mg PO
47.7 mg to 95.4 mg PO
1.6 mg to 3.2 mg PO
5.3 mg to 2.7 mg PO
The Correct Answer is A
Convert the child's weight from pounds (lb) to kilograms (kg).
Client weight: 35 lbs
Conversion factor: 1 kg = 2.2 lbs
Weight (kg) = 35 lbs / 2.2 lbs/kg
= 15.909 kg.
Determine the minimum safe single dose in milligrams (mg/dose).
Minimum recommended rate: 3 mg/kg/day
Dosing frequency: q8h (3 doses per day)
Minimum single dose (mg) = (3 mg/kg/day x Weight kg) / 3 doses/day
= 15.909 kg x 3 mg/kg/day / 3 doses/day
= 15.909 mg/dose
= 15.9 mg.
Determine the maximum safe single dose in milligrams (mg/dose).
Maximum recommended rate: 6 mg/kg/day
Dosing frequency: q8h (3 doses per day)
Maximum single dose (mg) = (6 mg/kg/day x Weight kg) / 3 doses/day
= 15.90909... kg x 6 mg/kg/day / 3 doses/day
= 31.81818... mg/dose
= 31.8 mg.

Correct Answer is A
Explanation
A. increased risk for speed shock: IV push medications enter the bloodstream rapidly, creating a high risk for speed shock, which is a toxic reaction caused by sudden drug administration. Symptoms may include dizziness, hypotension, irregular pulse, and cardiovascular collapse if not controlled.
B. increased risk for infiltration: Infiltration occurs when IV fluid or medication leaks into surrounding tissue. While possible with any IV therapy, it is not uniquely associated with IV push administration, since the risk is higher with prolonged infusions.
C. increased risk for infection: Infection risk is present with all IV routes due to potential contamination, but IV push does not specifically increase this risk compared to other IV methods when proper aseptic technique is followed.
D. a slow drug response: IV push produces one of the fastest drug responses because the medication is delivered directly into circulation. This makes it the opposite of a slow response, which is more characteristic of oral routes.
