The nurse is reviewing laboratory values for a client receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor?
AST and ALT
Prothrombin time (PT)
Activated partial thromboplastin time (aPTT)
International normalized ratio (INR)
The Correct Answer is C
A. AST and ALT are liver enzymes, primarily used to assess liver function, not directly related to monitoring heparin therapy.
B. Prothrombin time (PT) is used to monitor warfarin therapy, not heparin. Heparin therapy is typically monitored with aPTT, whereas warfarin is monitored with PT/INR.
C. Heparin is an anticoagulant that works by inhibiting clotting factors, and the aPTT is used to monitor its effectiveness. The aPTT measures the time it takes for blood to clot and helps ensure the heparin dose is therapeutic without causing excessive bleeding. The typical therapeutic range for aPTT on heparin therapy is 1.5 to 2.5 times the normal value.
D. INR is used to monitor warfarin therapy, not heparin. Heparin does not affect INR levels.

Correct Answer is ["8"]
Explanation
Calculate the total infusion time:
Total volume (mL) / Infusion rate (mL/hr) = Infusion time (hours)
1000 mL / 125 mL/hr = 8 hours
Therefore, the IV pump should infuse the 1-liter bag of 0.9% sodium chloride over 8 hours.
