Final answer:
The nurse should anticipate the prescription of Tranexamic acid [Cyklokapron] as an adjunct to factor VIII for a patient with hemophilia A undergoing tooth extraction because it helps in stabilizing the clot formation.
Step-by-step explanation:
For a patient with hemophilia A undergoing a tooth extraction, the nurse should anticipate an order for an adjunct to factor VIII treatment. Among the options provided, the best choice would likely be tranexamic acid [Cyklokapron], a medication known to help stabilize clots that do form and is often used in situations where bleeding risk is increased. Option (a) Tranexamic acid is commonly used in conjunction with factor VIII to help manage bleeding in patients with hemophilia. Acetaminophen is a pain reliever and would not be primarily used to control bleeding.
Desmopressin can help release stored factor VIII in some patients with mild hemophilia A but would not typically be used during tooth extraction for someone already receiving factor VIII. Lastly vitamin K is involved in the synthesis of certain clotting factors and would not be the medication of choice for someone with hemophilia A which is due to a deficiency of factor VIII specifically.
