Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding.

Correct Answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting.

Correct Answer: A

Rationale: Warfarin is classified as an anticoagulant, which means its primary function is to prevent the formation of blood clots. By inhibiting the synthesis of certain clotting factors in the liver, warfarin reduces the blood's ability to clot, making it an important medication in preventing conditions like strokes and deep vein thrombosis.

Correct Answer: B

Rationale: The correct instruction for a client using nitroglycerin transdermal patches is to remove the patch every night before bedtime. This is essential to prevent tolerance to the medication's effects. Continuous exposure to nitroglycerin can lead to the body becoming less responsive to its therapeutic effects over time, making it less effective in managing the condition it is prescribed for.

Correct Answer: B
