A nurse is caring for a client who is experiencing warfarin toxicity. Which of the following medications should the nurse administer?

Protamine sulfate

Vitamin K

Calcium gluconate

Acetylcysteine

Answer and Explanation

The Correct Answer is B

A. Protamine sulfate: Protamine sulfate is used to reverse the effects of heparin, not warfarin. Administering it in warfarin toxicity would not effectively counteract the anticoagulant effect and could delay appropriate treatment.

B. Vitamin K: Vitamin K is the antidote for warfarin toxicity. It promotes synthesis of clotting factors II, VII, IX, and X, which are inhibited by warfarin, helping to restore normal coagulation and reduce the risk of bleeding.

C. Calcium gluconate: Calcium gluconate is primarily used to treat hypocalcemia or cardiac effects of hyperkalemia. It does not reverse warfarin-induced anticoagulation and would not address the underlying risk of bleeding.

D. Acetylcysteine: Acetylcysteine is an antidote for acetaminophen toxicity and works by replenishing glutathione. It has no effect on warfarin metabolism or clotting factor synthesis, making it inappropriate for this scenario.

Free Nursing Study Resources

Correct Answer is C

Explanation

A. The website URL is listed as com: A ".com" domain indicates a commercial site and does not guarantee the accuracy or credibility of health information. Commercial sites may have marketing motives that can bias the content.

C. The author cites references to statements made: Providing references to scientific studies or reputable sources demonstrates that the information is evidence-based and allows verification. Cited references indicate that the content is grounded in credible medical research, enhancing trustworthiness.

D. The website was last updated 3 years ago: Health information can become outdated quickly. A last update from several years ago may not reflect current guidelines or best practices, reducing the reliability of the resource.

A. Social worker B. Primary care provider C. Physical therapist D. Occupational therapist

Correct Answer is A

Explanation

A. Social worker: Social workers can assist clients who have difficulty with transportation by coordinating community resources, arranging rides, or providing access to transportation services. This ensures the client can safely attend follow-up appointments without compromising independence or safety.

B. Primary care provider: The primary care provider manages overall health and follow-up care but does not typically coordinate transportation services for clients.

C. Physical therapist: Physical therapists focus on improving mobility, strength, and balance, which may indirectly support functional independence, but they do not coordinate transportation.

D. Occupational therapist: Occupational therapists help clients maintain or regain functional skills for daily activities, including driving skills, but arranging transportation to appointments falls under social work support rather than therapy interventions.
