A client is receiving heparin IV at a rate of 1,800 units/hour. The IV solution is labeled, "Heparin sodium 20,000 units in 5% dextrose Injection 500 mL." After receiving the partial thromboplastin time (PTT) result, the healthcare provider prescribes an increase of 5 ml/hour in the IV rate. The nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric value only.)
Answer and Explanation

The Correct Answer is ["50"]

First, we need to find out how many mL/hr the infusion pump is currently delivering.

Given:

The client is receiving 1,800 units/hour of heparin.

The available medication is 20,000 units/500 mL.

 

We can set up the proportion as follows:

1,800 units/ x mL  ​= 20,000 units​/500 mL

Solving for x gives us the volume in mL that the infusion pump is currently delivering per hour.

Cross-multiplying and solving for x:

X  = 1,800 units×500 mL​/20,000 units

After performing the calculation, we find that x equals 45 mL/hr.

Given that the healthcare provider prescribes an increase of 5 mL/hr in the IV rate, the nurse should set the infusion pump to deliver:

New rate (mL/hr) = Current rate (mL/hr) + Increase (mL/hr) = 45 mL/hr+5 mL/hr

After performing the calculation, we find that the new rate equals 50 mL/hr.

So, the nurse should set the infusion pump to deliver 50 mL/hr.

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 ["0.25"]

Explanation

Here's how to calculate the volume (mL) the nurse should administer for somatropin:

1. We know the following:

Prescribed dose: 1.25 mg somatropin (given)

Concentration after reconstitution: 5 mg/mL (given)

2. We need to find the volume (mL) to administer for the prescribed dose (1.25 mg) considering the concentration (5 mg/mL) of the reconstituted solution.

Volume to administer (mL): Dose (mg) / Concentration (mg/mL)

Volume to administer (mL): 1.25 mg / 5 mg/mL

Volume to administer (mL) = 0.25 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.25 mL of the reconstituted somatropin solution subcutaneously.
