A patient with a history of atrial fibrillation has contacted the clinic saying that she has accidentally overdosed on her prescribed warfarin (Coumadin). The nurse should recognize the possible need for what antidote?
Factor VIII
Vitamin K
IVIG
Factor X
The Correct Answer is B
A. Factor VIII: Factor VIII is a component of the clotting cascade, but it is not the antidote for warfarin. Factor VIII is used in the treatment of hemophilia A.
B. Vitamin K: This is the correct answer. Vitamin K is the antidote for warfarin overdose. It helps in the synthesis of clotting factors.
C. IVIG (Intravenous Immunoglobulin): IVIG is not an antidote for warfarin. It is used for various immune-related conditions.
D. Factor X: Factor X is also a clotting factor, but it is not the antidote for warfarin. Factor Xa inhibitors are used as anticoagulants.

Correct Answer is ["A","B","C","D"]
Explanation
Withhold food and oral fluids before the procedure
Withholding food and oral fluids before the procedure is essential to prevent complications during the cardiac catheterization. The client is typically NPO (nothing by mouth) for a specified period before the procedure.
B. Review medications the client has taken in the last 24 hours
Reviewing the client's medications is crucial to ensure that any medications affecting coagulation or blood vessels are appropriately managed before the cardiac catheterization.
C. Verify that written consent has been obtained
Verifying the presence of written consent is a critical step to confirm that the client has been adequately informed about the procedure, its risks, and benefits, and has given consent for the cardiac catheterization.
D. Check for iodine sensitivity
Checking for iodine sensitivity is important because iodinated contrast dye is commonly used during cardiac catheterization. Allergies or sensitivities to iodine contrast must be identified to prevent adverse reactions.
E. Administer all ordered oral medications
Administration of oral medications before the procedure depends on the specific medications and the healthcare provider's instructions. Some medications may be held, while others may be continued as prescribed.
Correct Answer is ["125"]
Explanation
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.
