A heparin infusion is prescribed for a client who weighs 220 pounds. After administering a bolus dose of 80 units/kg, the nurse calculates the infusion rate for the heparin solution at 18 units/kg/hour. The available solution is "Heparin Sodium 25,000 Units in 5% Dextrose Injection 250 mL". The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["18"]
Calculation:
- Convert the client's weight from pounds (lb) to kilograms (kg).
The client's weight is 220 lb.
Client weight (kg) = 220 lb/2.2 lb/kg
= 100 kg.
- Calculate the total heparin dose to be administered per hour (units/hr).
The ordered rate is 18 units/kg/hour.
Total dose rate (units/hr) = 18 units/kg/hour×100 kg
= 1800 units/hr.
- Determine the concentration of the available solution (units/mL).
Available solution is 25,000 units in 250 mL.
Concentration (units/mL) = 25,000 units/250 mL
= 100 units/mL.
- Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total dose rate (units/hr)/Concentration (units/mL)
= 1800 units/hr/100 units/mL
= 18 mL/hr.

Correct Answer is A
Explanation
A. Bring a sterile chest drainage unit from central supply to the unit: This task is appropriate for delegation to a UAP because it involves transporting equipment and does not require clinical judgment or assessment.
B. Evaluate a client's urinary catheter for proper drainage: This requires assessment skills to determine whether the catheter is functioning correctly or if complications such as obstruction or infection are present.
C. Call the pharmacy to obtain a client's next antibiotic dose: Communicating directly with the pharmacy about medications is part of the nurse’s responsibilities. It involves ensuring accuracy, safety, and proper coordination of care, which cannot be delegated to unlicensed staff.
D. Observe a client's gait to determine the need for assistance: While a UAP can walk with a client or provide basic support, determining the level of assistance needed requires assessment skills. Evaluating gait involves clinical judgment and must be performed by a licensed nurse or physical therapist.

Explanation
To measure blood pressure from the left thigh, the diaphragm of the stethoscope should be placed over the popliteal artery, which is located behind the knee. This placement allows you to auscultate the Korotkoff sounds accurately when measuring thigh blood pressure.
