A child who weighs 40 kg receives a prescription for acetaminophen 15 mg/kg/dose PO every 4 to 6 hours PRN for fever. What is the maximum daily dose the nurse should administer? (Enter the numerical value only.)

Answer and Explanation

The Correct Answer is ["3600"]

Here's how to calculate the maximum daily dose of acetaminophen for the child:

Calculate the maximum dose per administration:

Maximum dose per kg per administration = 15 mg/kg (given)

Child's weight = 40 kg (given)

Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage.

Maximum dose per administration = 15 mg/kg/dose * 40 kg

Maximum dose per administration = 600 mg (round to nearest whole number)

Calculate the number of administrations in a 24-hour period (maximum):

Frequency: Every 4 to 6 hours PRN (given)

Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose.

Number of administrations (maximum) = 24 hours / Frequency (hours/administration)

Number of administrations (maximum) = 24 hours / 4 hours/administration

Number of administrations (maximum) = 6 administrations

Calculate the maximum daily dose:

Maximum daily dose = Maximum dose per administration x Number of administrations (maximum)

Maximum daily dose = 600 mg/administration * 6 administrations

Maximum daily dose = 3600 mg

Therefore, the maximum daily dose the nurse should administer is 3600 mg.

Correct Answer is ["0.5"]

Explanation

Here's how to calculate the volume the nurse should administer after reconstituting the medication:

1. Reconstitution and Concentration:

The medication label states adding 2.5 mL of normal saline will make a solution with a concentration of 1 gram per mL. This means after reconstituting, each 1 mL of the solution will contain 1 gram of medication.

2. Dose conversion:

The client's prescription is for 500 mg. We need to convert it to grams since the concentration is in grams per mL.

Conversion: 1 gram (g) = 1000 milligrams (mg)

Prescribed dose (g) = 500 mg / 1000 mg/g

Prescribed dose (g) = 0.5 g (round to nearest tenth)

3. Calculate the volume to administer:

We know the concentration after reconstitution (1 gram/mL) and the desired dose in grams (0.5 g).

Volume to administer (mL) = Dose (g) / Concentration (g/mL)

Volume to administer (mL) = 0.5 g / 1 g/mL

Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)

Therefore, the nurse should administer approximately 0.5 mL of the reconstituted medication to the client.

Correct Answer is ["21"]

Explanation

Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:

1. We know:

Total volume of D5W solution: 2 L (liters)

Infusion time: 24 hours

IV administration set gtt/mL: 15 gtt/mL

2. We need to find the infusion rate in gtt/min.

Steps:

a. Convert liters to milliliters (mL) for better calculation:

1 liter = 1000 mL

Total volume (mL) = 2 L * 1000 mL/L

Total volume (mL) = 2000 mL

b. Convert infusion time from hours to minutes:

Infusion time (minutes) = Infusion time (hours) x Minutes per hour

Infusion time (minutes) = 24 hours * 60 minutes/hour

Infusion time (minutes) = 1440 minutes

c. Calculate the total volume of solution to be infused per minute:

Volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)

Volume rate (mL/min) = 2000 mL / 1440 minutes

Volume rate (mL/min) = 1.389 mL/min (round to nearest hundredth)

d. Finally, calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL

Infusion rate (gtt/min) = 1.389 mL/min * 15 gtt/mL

Infusion rate (gtt/min) = 20.835 gtt/min (round to nearest whole number as requested)

Therefore, the nurse should regulate the infusion at approximately 21 gtt/min
