ATI Pharmacology Exam 2 Questions

Extract:


Question 1 of 5

A nurse is reviewing laboratory results of a client who has atrial fibrillation and is taking warfarin. For which of the following results should the nurse notify the provider?

Correct Answer: C

Rationale: The correct answer is C: PT 45 seconds. This result indicates prolonged prothrombin time, which may suggest that the client's blood is not clotting properly. In a client taking warfarin, which is an anticoagulant, a prolonged PT may indicate a risk of bleeding. The nurse should notify the provider to adjust the warfarin dosage to prevent bleeding complications.
Other choices are within normal ranges for a client taking warfarin. Platelets at 190,000/mm3 are normal, Hct at 44% is within the expected range, and Hgb at 16 g/dL is also normal. These results do not indicate immediate concerns related to the client's condition and medication.
