Question

1. aspirin.
2. vitamin B12 supplementation.
3. warfarin.
4. penicillin.

Answer 1

Correct Answer: 3
Rationale 1: A client taking aspirin and levothyroxine concurrently would not require careful monitoring.
Rationale 2: A client taking vitamin B12 supplementation and levothyroxine concurrently would not require careful monitoring.
Rationale 3: A client taking warfarin and levothyroxine concurrently might need a decrease in dosage to prevent bleeding.
Rationale 4: A client taking penicillin and levothyroxine concurrently would not require careful monitoring.
Global Rationale: A client taking warfarin and levothyroxine concurrently might need a decrease in dosage to prevent bleeding. There is no reason for special monitoring for concurrent use of aspirin, vitamin B12, or penicillin.
