Answer to Question 1

2,5,4,1,3

Global Rationale: When blood level of thyroid hormone is low, the hypothalamus secretes thyroid-releasing hormone, which stimulates secretion of thyroid-stimulating hormone. This stimulates production and secretion of T3 and T4. As the levels of thyroid hormones rise, the secretion of TSH and TRH are suppressed.

Answer to Question 2

3

Rationale 1:Citalopram (Celexa) is incorrect because this medication is an SSRI.
Rationale 2:Fluoxetine (Prozac) is incorrect because it is an SSRI.
Rationale 3: Tranylcypromine (Parnate) is an MAOI.
Rationale 4:Amitriptyline (Elavil) is incorrect because this medication is a tricyclic antidepressant.

Global Rationale: Tranylcypromine (Parnate) is an MAOI. Citalopram (Celexa) is incorrect because this medication is an SSRI. Fluoxetine (Prozac) is incorrect because it is an SSRI. Amitriptyline (Elavil) is incorrect because this medication is a tricyclic antidepressant.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
