A client is to receive furosemide 60 mg IV every 12 hours. The medication is available in a concentration of 10 mg/mL, and based on the manufacturer's recommendations, the nurse plans to administer the dosage over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
Answer and Explanation

The Correct Answer is ["18"]

Here's how to calculate the infusion rate (mL/hour) for the nurse to administer furosemide 60 mg IV every 12 hours:

1. Furosemide dose per administration:

Dose = 60 mg (given)

2. Dosage frequency (conversion from hours to minutes):

Frequency (minutes) = 12 hours/dose * 60 minutes/hour

Frequency (minutes) = 720 minutes/dose

3. Medication concentration:

Concentration = 10 mg/mL (given)

4. Infusion duration:

Duration = 20 minutes (given)

5. We need to find the total volume (mL) of the medication to be delivered and then convert that volume to a rate per hour (mL/hour).

Steps:

a. Calculate the volume to be infused (mL):

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Volume (mL) = 60 mg / 10 mg/mL

Volume (mL) = 6 mL

b. Convert infusion duration from minutes to hours:

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

Infusion time (hours) = 20 minutes / 60 minutes/hour

Infusion time (hours) = 1/3 hour

c. Calculate the infusion rate (mL/hour):

Infusion rate (mL/hour) = Volume (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 6 mL / (1/3 hour)

Infusion rate (mL/hour) = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver approximately 18 mL/hour.

Correct Answer is ["3600"]

Explanation

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 ["59.147"]

Explanation

Here's how to calculate the number of mL the nurse should document:

Client dosage: 2 ounces (given)

Conversion factor: 1 ounce (oz) = 29.5735 mL (conversion factor)

Magnesium hydroxide concentration: 400 mg per 5 mL (from bottle label)

We need to find the equivalent volume in mL of the 2 ounces dosage the client reported.

Steps:

a. Convert ounces to mL:

Client dosage (mL) = Client dosage (oz) x Conversion factor (mL/oz)

Client dosage (mL) = 2 oz * 29.5735 mL/oz

Client dosage (mL) = 59.147 mL (round to nearest hundredth)
