A primary healthcare provider has prescribed ertapenem to a 6-year-old child with a urinary tract infection (UTI). What is the safe dose of medication for this child?
1g/kg every 8 hours
500 mg/kg three times daily
5 g/kg once daily
15 mg/kg twice daily
The Correct Answer is D
1g/kg every 8 hours is incorrect because it exceeds the recommended dose.
According to the package insert for Ertapenem, the dose for patients 3 months to 12 years of age is 15 mg/kg twice daily (not to exceed 1 g/day) .
A. 1g/kg every 8 hours is incorrect because it exceeds the recommended dose.

Correct Answer is A
Explanation
To calculate the rate of infusion required for the continuous intravenous (IV) infusion of 1.5 L of normal saline (NS) over 24 hours, we need to divide the total volume (1500 ml) by the total time (24 hours).
1500 ml / 24 hours = 62.5 ml/hr
Therefore, the rate of infusion that should be set in the infusion pump is a. 62.5 mL/hr.
B. 41.7 mL/hr: This rate is too low and would result in the infusion taking longer than the prescribed 24 hours.
C. 20.8 mL/hr: This rate is even lower and would result in an even longer infusion time, which is not consistent with the prescribed 24 hours.
D. 83.3 mL/hr: This rate is too high and would result in the infusion being delivered faster than the prescribed 24 hours.
Therefore, the correct rate of infusion to be set in the infusion pump for the continuous IV infusion of 1.5 L of normal saline over 24 hours is a. 62.5 mL/hr, as it ensures the prescribed volume is infused within the specified time frame.
Correct Answer is D
Explanation
The patient received heparin at a rate of 12 mL/hr for 2 hours (from 9:00 am to 11:00 am) and then at a rate of 10 mL/hr for 3 hours (from 11:00 am to 2:00 pm). The total volume of heparin solution infused is (12 mL/hr x 2 hr) + (10 mL/hr x 3 hr) = 54 mL. Since there are 25,000 units of heparin in 250 mL of solution, the concentration of heparin is 25,000 units / 250 mL = 100 units/mL. Therefore, the total amount of heparin received by the patient is 54 mL x 100 units/mL = **8900 units**.
A. 5400 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
B. 6800 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
C. 7200 units is not the correct answer because it does not account for the change in infusion rate at 11:00 am.
