Answer to Question 1

ANS: A
Myxedema patients are sensitive to small doses of sedative hypnotics, anesthetics, and narcotics. Increasing the analgesic would only make the patient feel more lethargic in the morning. The patient should not change the dose of his thyroid medication without consulting his primary health care provider. Any pain medication is likely to have this effect because of the patient's thyroid condition.

Answer to Question 2

ANS: D
Propylthiouracil and methimazole are antithyroid agents that act by blocking the synthesis of T3 and T4 in the thyroid gland. They do not destroy any T3 or T4 already produced, so there is usually a latent period of a few days to 3 weeks before symptoms improve once therapy is started. Antithyroid medications do not block reuptake of hormones, destroy hormones, or increase synthesis of hormone.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
