2024 PN NCLEX Questions Nursing Practice Question
Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:
Correct Answer: A
Rationale: Levothyroxine (Synthroid) is preferred for thyroid replacement therapy due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration, making it effective and easy for patients to manage.
Option B is incorrect as levothyroxine is available in various strengths, not just a single 25 mg tablet, complicating dosing for some patients. Option C is misleading; while levothyroxine is not a prodrug, this characteristic does not directly contribute to its effectiveness in thyroid replacement. Option D is also incorrect; levothyroxine has a relatively long half-life, which supports its once-daily dosing regimen.
