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.)
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

Correct Answer is A
Explanation
A. "Your pain will gradually become less severe." This statement is accurate and provides realistic expectations for the client. After an amputation, there will be initial post operative pain, but it should gradually decrease over time.
B. "The pain will disappear soon." This statement is not accurate. While the pain will eventually decrease, it may not completely disappear immediately after the procedure.
C. "It's likely that you will have only a tingling sensation." This statement is not accurate. While some clients may experience tingling sensations, it is not the only sensation they may feel, and this statement does not cover the full range of possible experiences.
D. "Phantom pain is mostly psychological." This statement is not accurate. Phantom pain is a real sensation that some individuals experience after an amputation. It is believed to be related to nerve endings that continue to send signals to the brain even though the limb is no longer present. It is not purely psychological.
