Answer to Question 1

ANS: B
Liothyronine has a short half-life and rapid onset of action and is not recommended for maintenance therapy but is used as initial therapy for severe myxedema. Levothyroxine is the drug of choice for replacement therapy. Liotrix is a second-line drug. Thyroid desiccated is used for hypothyroidism to reduce goiter size.

Answer to Question 2

ANS: C
Thyroid preparations increase the effect of oral anticoagulants, so the warfarin dose may need to be decreased. Levothyroxine can decrease the effectiveness of digoxin, so this dose may need to be increased.
