A nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. Available is heparin 25.000 units in dextrose 5% in water (DSW) 500 mL The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["32"]

1. Determine the concentration of heparin in the solution:

   - There are 25,000 units of heparin in 500 mL of D5W.

   - Concentration = 25,000 units / 500 mL = 50 units/mL.

 

2. Calculate the required mL/hr for the desired infusion rate:

   - The order is for 1600 units/hr.

   - To find the mL/hr:

 ML/HR=desired units/hr divided by unts/ml

=1600/50

=32ml/hr

Explanation

A. Mild erythema (redness) at the pin sites can be a normal finding due to the body's response to the presence of foreign objects. It may not necessarily indicate infection.

B. Serosanguineous drainage (a mixture of clear and bloody fluid) can also be a normal finding initially after the insertion of pins. It may not necessarily indicate infection.

C. Fever is a systemic response to infection. In a client with skeletal traction, fever can be an indication of an infection at the pin sites or a more systemic infection related to the traction device.

D. Warmth around the pin sites can be a normal finding due to the inflammatory response that occurs after pin insertion. It may not necessarily indicate infection.
