The nurse is to administer heparin to a client who weighs 90 pounds. Heparin is ordered as 10,000 units/100mL. The nurse needs to administer a bolus of 40units/kg. How many units would the nurse administer? (Round to the nearest tenth)
The Correct Answer is ["1636.4"]
- Convert pounds to kilograms:
- Weight in kilograms = 90 pounds / 2.2 pounds/kg = 40.9090... kg. For practical purposes, we can round to 40.91kg.
- Calculate the heparin dose:
- The ordered bolus dose is 40 units/kg.
- Heparin dose = 40.91 kg 40 units/kg = 1636.4 units.
- Round to the nearest tenth:
- The heparin dose is 1636.4 units.
= 1636.4 units
