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
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.

Correct Answer is A
Explanation
A. Observe the client during and after meals: Monitoring the client for bingeing or purging behaviors is the priority intervention because it addresses immediate safety and physical health risks, such as electrolyte imbalances. Direct observation prevents harmful behaviors and allows timely intervention.
B. Refer the client to a support group for clients who have eating disorders: Referral is important for long-term psychosocial support, but it does not address immediate risk or safety concerns during meals.
C. Instruct the client about effective coping strategies: Teaching coping strategies is beneficial for long-term management, but ensuring safety during meals takes precedence in the nursing process.
D. Suggest that the client assist with meal planning: Involving the client in meal planning promotes autonomy and engagement in treatment, but it is not the first action when immediate monitoring is required to prevent harmful behaviors.
Correct Answer is D
Explanation
A. Explain medical terminology using basic, one-syllable words: While simplifying language is important, limiting explanations to only one-syllable words may overly restrict clarity and precision. Key terms can be explained in plain language without compromising accuracy.
B. Present information from complex to simple: Effective teaching typically progresses from simple concepts to more complex ones. Presenting information in reverse can confuse readers and reduce comprehension, especially for health education materials.
C. Write the information at an 8th-grade reading level: Health education materials are most effective when written at a 5th- to 6th-grade reading level to ensure accessibility to a broad audience, including those with limited health literacy. Writing at an 8th-grade level may be too advanced for some readers.
D. Use a 12-point font size: Using a 12-point font enhances readability, especially for older adults or individuals with visual impairments. Clear, legible text supports comprehension and encourages engagement with the educational material.
