Extract:
Question 1 of 5
The nurse is caring for a client who is being evaluated for possible deep vein thrombosis of the right extremity. Which laboratory result is of most concern to the nurse?
Correct Answer: B
Rationale: A D-dimer level of 500 ng/mL is elevated, which can indicate the presence of a clot, such as in DVT.
Question 2 of 5
A client is receiving heparin sodium 1000 units per hour via an infusion and warfarin sodium 2.5 mg PO for thrombophlebitis in the left leg. The nurse educates the client that heparin and warfarin are prescribed together because:
Correct Answer: C
Rationale: Heparin acts quickly to prevent further clotting, while warfarin takes several days to become effective. Thus, heparin is used to provide immediate anticoagulation until warfarin becomes effective.
Question 3 of 5
The nurse is providing care for a client diagnosed with post-thrombotic syndrome who has a venous stasis ulcer. Which instructions should be given prior to discharge? (Select all that apply)
Correct Answer: A,B,E
Rationale: Proteins, vitamin C, and zinc are essential for wound healing. Care should be taken when walking to avoid bumping the limb, as trauma could worsen the condition. Compression stockings reduce swelling and improve blood flow, promoting ulcer healing.
Question 4 of 5
A patient diagnosed with deep vein thrombosis asks the nurse, "How does this blood thinner heparin work?" Which response is most accurate?
Correct Answer: C
Rationale: Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
Question 5 of 5
The nurse is explaining to a patient why oral antihyperglycemic agents are not effective in Type 1 diabetes. What is the reason?
Correct Answer: A
Rationale: People with Type 1 diabetes have little or no insulin that can be released due to the destruction of pancreatic β-cells, making oral antihyperglycemic agents ineffective.
