Answer to Question 1

Correct Answer: 1,2
Rationale 1: The serum T4 level is used to determine primary hypothyroidism.
Rationale 2: The TSH level is used to determine primary hypothyroidism.
Rationale 3: The serum calcium level is not used to determine primary hypothyroidism.
Rationale 4: The serum potassium level is not used to determine primary hypothyroidism.
Rationale 5: The serum iodine level is not used to determine primary hypothyroidism.
Global Rationale: Primary hypothyroidism is characterized by a low serum T4 level and an elevated TSH level. Serum levels of calcium, potassium, and iodine are not significant to the diagnosis.

Answer to Question 2

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.
