Question

Effective heparin therapy elevates the Partial Thromboplastin Time (PTT) to approximately _______ times normal.

a) 1.5 to 2
b) 2 to 2.5
c) 2.5 to 3
d) 3 to 4

Answer 1

Effective heparin therapy elevates the PTT to approximately 2 to 2.5 times normal.

Step-by-step explanation:

Effective heparin therapy elevates the Partial Thromboplastin Time (PTT) to approximately 2 to 2.5 times normal. The PTT is a laboratory test used to measure the time it takes for blood to clot. Heparin is an anticoagulant medication that extends the clotting time, thus increasing the PTT. This measurement is important in monitoring the effectiveness of heparin therapy and ensuring the patient is receiving an appropriate dosage.
