The nurse discovers a patient receiving warfarin is bleeding.
What drug would the nurse prepare to counteract this drug?
Vitamin E.
Protamine Sulfate.
Calcium Gluconate.
Vitamin K.
The Correct Answer is D
Choice A rationale
Vitamin E is an antioxidant and is not indicated to counteract the effects of warfarin. It does not have a role in reversing anticoagulation or managing bleeding. High doses of Vitamin E can actually interfere with clotting and potentially exacerbate bleeding.
Choice B rationale
Protamine Sulfate is an antidote for heparin, not warfarin. It works by neutralizing the effects of heparin, which is an anticoagulant that acts quickly to prevent clot formation. Warfarin works differently and requires a different antidote for its anticoagulant effect.
Choice C rationale
Calcium Gluconate is not an antidote for warfarin. It is typically used in cases of hypocalcemia and can stabilize cardiac membranes in hyperkalemia but has no effect on reversing warfarin-induced anticoagulation or bleeding.
Choice D rationale
Vitamin K is the correct antidote for warfarin. It counteracts the anticoagulant effects by promoting the synthesis of clotting factors that warfarin inhibits. Administering Vitamin K is standard practice in reversing the effects of warfarin and managing bleeding complications.

Explanation
Choice A rationale
Barrier contraceptives are recommended for women taking HMG-CoA reductase inhibitors due to the potential teratogenic effects of these drugs. This precaution is crucial as these medications can cause fetal harm if used during pregnancy.
Choice B rationale
While ophthalmic examinations may be important for other medications, they are not a primary concern for HMG-CoA reductase inhibitors. These drugs mainly affect cholesterol synthesis and have less direct impact on vision.
Choice C rationale
Although a cholesterol-lowering diet is beneficial, it is not the primary teaching point when discussing HMG-CoA reductase inhibitors. The emphasis should be on medication adherence and managing potential adverse effects.
Choice D rationale
Reporting respiratory symptoms is important for many medications but is not the primary focus for HMG-CoA reductase inhibitors. The priority is to inform patients about the importance of contraception and potential side effects related to the medication.
