Correct Answer is B

Explanation

A. Prothrombin time (PT) is used to monitor warfarin therapy, not heparin therapy.

B. Activated partial thromboplastin time (aPTT) is the primary laboratory test used to assess the effectiveness of heparin therapy, measuring the time it takes for blood to clot and ensuring therapeutic levels.

C. The International normalized ratio (INR) is also related to warfarin therapy rather than heparin.

D. Serum potassium level is not relevant for assessing heparin therapy but may be monitored for other reasons.

Correct Answer is ["0.6"]

Explanation

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case:

Desired dose = 6000 units
Concentration = 10000 units/mL

Plugging the values into the formula:

Volume = 6000 units / 10000 units/mL = 0.6 mL
