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.)
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 ["5"]
Explanation
Here's how to calculate the volume of medication the nurse should administer on the first day:
1. Convert child's weight to kilograms (kg):
We know 1 kg = 2.205 pounds.
Child weight (kg) = 44 pounds / 2.205 pounds/kg = 20 kg (round to nearest whole number for this calculation).
2. Calculate the total azithromycin medication for the first day (mg):
Prescribed dosage (mg/kg): 10 mg/kg
Child weight (kg): 20 kg (rounded value from step 1)
Total medication on day 1 (mg) = Dosage (mg/kg) x Client weight (kg)
Total medication on day 1 (mg) = 10 mg/kg x 20 kg = 200 mg
3. Determine the volume (mL) needed based on the medication concentration:
Medication concentration (mg/mL): 200 mg/5 mL (given)
Total medication on day 1 (mg): 200 mg (calculated in step 2)
Volume to administer (mL) = Total medication (mg) / Concentration (mg/mL)
Volume to administer (mL) = 200 mg / 200 mg/5 mL
Volume to administer (mL) = 5 mL
Therefore, the nurse should administer 5 mL of the azithromycin solution on the first day.
Correct Answer is ["0.5"]
Explanation
Here's how to calculate the volume of heparin the nurse should administer:
1. Heparin dose: 5,000 units (given)
2. Heparin concentration: 10,000 units/mL (given on the vial label)
We need to find the volume (mL) containing the prescribed dose (5,000 units) of heparin.
Calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 5,000 units / 10,000 units/mL
Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.5 mL of heparin.
