A nurse is reviewing laboratory results for four clients who are scheduled for surgery. Which of the following laboratory values should the nurse report to the surgeon?

Platelets 95,000/mm

MCT 42%

WBC count 8,000/mm

INR of 1.6

Answer and Explanation

The Correct Answer is A

A platelet count of 95,000/mm is below the normal range of 150,000 to 400,000/mm and indicates thrombocytopenia, which increases the risk of bleeding during surgery. The nurse should report this value to the surgeon and anticipate interventions such as transfusion of platelets or postponement of surgery. The other values are within normal limits and do not require immediate attention.

A high calcium level (hypercalcemia) can indicate complications of TPN, such as bone demineralization, renal calculi, or metabolic alkalosis. The nurse should notify the provider of this finding and expect to adjust the TPN formula or administer fluids and diuretics to lower the calcium level. The other options are within normal or expected ranges for a client receiving TPN.
