Question 4 of 5
Following long-term administration of warfarin sodium to a client with deep vein thrombosis, the nurse should expect which outcome?
Correct Answer: A
Rationale: After long-term warfarin for deep vein thrombosis, the nurse should expect the prothrombin time (PT) to be 1.5 to 2 times the normal value (or INR 2-3), indicating therapeutic anticoagulation. Warfarin inhibits vitamin K-dependent clotting factors, prolonging PT to prevent clot extension. PTT is more relevant for heparin, not warfarin, and hematocrit/hemoglobin levels aren't directly affected by anticoagulation unless bleeding occurs. PT prolongation is the standard measure of warfarin's efficacy in this context.
Question 5 of 5
After several days of coughing and taking acetaminophen to treat temperatures of 101°F, a client with diabetes mellitus is admitted to the hospital with an upper respiratory infection. Several hours after admission, the client reports having a severe headache and feeling dizzy. Which intervention should the nurse implement?
Correct Answer: D
Rationale: For a diabetic client with a respiratory infection reporting severe headache and dizziness, the nurse should obtain a fingerstick glucose. These symptoms could indicate hypo- or hyperglycemia, common in diabetes during illness due to stress or altered intake, potentially worsened by acetaminophen masking fever. Antipyretics address fever, vital signs give general status, and sputum culture targets infection, but glucose checks directly address a life-threatening metabolic cause in this context, making it the priority.
