Correct Answer is ["50"]
Explanation
First, let’s calculate the current infusion rate in mL/hour.
The IV solution contains 20,000 units of heparin in 500 mL, so the concentration is:
Concentration = Totalunits/ Totalvolume = 20,000units /500mL = 40units/mL
The client is currently receiving 1,800 units/hour. At a concentration of 40 units/mL, this dosage is equivalent to:
Currentrate = Dose/ Concentration = 1,800units/hour / 40units/mL = 45mL/hour
The healthcare provider prescribed an increase of 5 mL/hour in the IV rate. Therefore, the new rate should be:
Newrate = Currentrate + Increase = 45mL/hour + 5mL/hour = 50mL/hour
So, the nurse should set the infusion pump to deliver 50 mL/hour. If rounding is required, this is already rounded to the nearest whole number.
Correct Answer is ["168"]
Explanation
Here's how to calculate the total zidovudine dosage (mg) the nurse should prepare to administer:
1. Convert client weight from pounds to kilograms:
Client weight (kg) = Client weight (lb) / 2.2
Client weight (kg) = 185 lb / 2.2
Client weight (kg) = 84.1 kg (approximately)
2. Calculate the total zidovudine dose based on weight and prescribed dosage:
Dose (mg) = Dose (mg/kg) x Client weight (kg)
Dose (mg) = 2 mg/kg x 84.1 kg
Dose (mg) = 168.2 mg (round to nearest whole number as requested)
Therefore, the nurse should prepare to administer 168 mg of zidovudine.
