A patient develops a postoperative deep vein thrombosis and is started on IV heparin. Which of the ff. laboratory tests is monitored during the heparin therapy?
- A. Plasma fibrinogen c.Partial thromboplastin time (PTT)
- B. Prothrombin time (PT)
- C. International normalized ratio (INR)
Correct Answer: C
Rationale: During heparin therapy, the laboratory test that is monitored is the partial thromboplastin time (PTT). Heparin acts by potentiating the activity of antithrombin III, leading to the inhibition of both thrombin and factor Xa. The PTT measures the intrinsic pathway of coagulation and is prolonged with heparin due to its anticoagulant effect. Monitoring the PTT helps to ensure that the patient is within the therapeutic range of anticoagulation to prevent clot formation without increasing the risk of bleeding complications. Plasma fibrinogen, prothrombin time (PT), and international normalized ratio (INR) are not routinely monitored during heparin therapy.

A clinical feature that distinguishes a hypoglycemic reaction from a ketoacidosis reaction is:
- A. blurred vision.
- B. diaphoresis.
- C. nausea.
- D. weakness. 117
Correct Answer: B
Rationale: Diaphoresis, which refers to excessive sweating, is a common clinical feature seen in a hypoglycemic reaction. Hypoglycemia occurs when the blood sugar level drops too low, leading to symptoms like sweating, shakiness, confusion, and rapid heartbeat. On the other hand, ketoacidosis is a serious complication of diabetes that occurs when there is a lack of insulin, causing high blood sugar levels and the body to break down fat for energy. Symptoms of ketoacidosis include nausea, vomiting, abdominal pain, and fruity-smelling breath, but diaphoresis is not typically a prominent feature. Therefore, diaphoresis can help clinicians differentiate between hypoglycemic and ketoacidosis reactions.
