Gastric analysis

Stool culture

Answer and Explanation

The Correct Answer is C

A) Incorrect. Gastric analysis is not commonly used to confirm the presence of blood in the stomach or identify the source of bleeding.

B) Incorrect. Anticoagulant therapy is not associated with elevated blood pressure readings.

C) Incorrect. Hyperactivity and restlessness are not typical adverse effects of anticoagulant therapy.

D) Incorrect. Anticoagulant therapy does not increase blood viscosity (thickness); instead, it reduces the blood's ability to form clots.
