A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?
aPTT
PT
INR
WBC count
The Correct Answer is A
A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.
B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.
C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.
D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"D"}
Explanation
The client is at highest risk for developing hypocalcemia as evidenced by the total calcium level of 8.0 mg/dL (normal range 9.0 to 10.5 mg/dL).
Explanation:
After a total thyroidectomy, there is a risk of hypocalcemia due to potential damage or removal of the parathyroid glands, which regulate calcium levels in the body. The laboratory result indicating a total calcium level of 8.0 mg/dL, which is below the normal range, supports this risk. Hypocalcemia can lead to symptoms such as tingling, muscle cramps, or more severe complications like cardiac arrhythmias if not addressed promptly.
