Answer to Question 1

Correct Answer: 1
Primary hypothyroidism emanates from the thyroid gland itself. Laboratory analysis will indicate an elevated TSH, as the pituitary attempts to stimulate the thyroid gland to produce thyroid hormone, and the thyroid hormone levels T3 and T4 will be low. Elevated T3 and T4 levels are not consistent with hypothyroidism. TSH is depressed in hyperthyroidism.

Answer to Question 2

Correct Answer: 1, 2

Myxedema coma usually occurs in older adults and may be precipitated by pneumonia, gastrointestinal bleeding, and the use of central nervous system depressants. Excessive use of thyroid replacement medications, central nervous system stimulants, or exposure to heat and humidity would not precipitate myxedema coma.
