What is the safe dose of medication for this child?

500 mg/kg three times daily

5 g/kg once daily

1 g/kg every 8 hours

15 mg/kg twice daily

Answer and Explanation

The Correct Answer is D

The safe dose of ertapenem for children is **15 mg/kg** twice daily, with a maximum dose of **500 mg** per dose. Therefore, the correct answer is **d) 15 mg/kg twice daily**. Ertapenem is a carbapenem antibiotic that is used to treat various infections caused by susceptible bacteria.

Correct Answer is A

Explanation

To calculate the infusion rate, we need to convert the patient's weight from kilograms to milligrams.

Patient's weight: 65 kg

Dose required: 200 mcg/kg/min

First, let's calculate the total dose required for the patient per minute: Dose required = 200 mcg/kg/min * 65 kg

= 13,000 mcg/min

Next, we need to convert the dose from micrograms to milligrams:

13,000 mcg/min = 13 mg/min

Now, let's determine the infusion rate. We have 2,500 mg of esmolol in 250 mL of ﬂuid. Therefore, the concentration of esmolol in the ﬂuid is:

Concentration = 2,500 mg / 250 mL

= 10 mg/mL

To find the infusion rate, we divide the dose required by the concentration: Infusion rate = 13 mg/min / 10 mg/mL

= 1.3 mL/mi

Since the options are in mL/hr, we need to convert the rate from mL/min to mL/hr:

1.3 mL/min * 60 min/hr = 78 mL/hr

Therefore, the correct answer is:

a. 78 mL/hr

A. 45 mL/hr B. 60 mL/hr C. 75 mL/hr D. 90 mL/hr

Correct Answer is C

Explanation

To calculate the rate (in mL/hr) at which the IV pump should be programmed to deliver the dose of esmolol, we can use the following formula:

Rate (mL/hr) = (Dose × Patient weight × 60) / (Concentration × Time)

Given:

Dose = 2.5 grams Patient weight = 110 lb Concentration = 250 mL

Time = 1 hour (since the dose is given per hour)

Converting the patient's weight from pounds to kilograms:

Patient weight = 110 lb ÷ 2.2046 = 49.9 kg

Substituting the values into the formula:

Rate (mL/hr) = (2.5 g × 49.9 kg × 60) / (250 mL × 1)

Simplifying the equation:

Rate (mL/hr) = (2.5 × 49.9 × 60) / 250

Rate (mL/hr) = 74.85

Rounding to the nearest whole number, the nurse should program the IV pump to deliver 75 mL/hr.

Therefore, the correct answer is c. 75 mL/hr.
