Answer to Question 1

ANS: A
Turner syndrome is caused by an absence of one of the X chromosomes. Most girls who have this disorder have one X chromosome missing from all cells. No Y chromosome is present in individuals with Turner syndrome. This young woman has 45 rather than 46 chromosomes.

Answer to Question 2

ANS: D
First-line therapy for adolescents with dysmenorrhea is NSAIDs. This group of drugs blocks the formation of prostaglandins. NSAIDs, not aspirin, are the drugs of choice in dysmenorrhea. NSAIDs are potent anti-inflammatory agents that inhibit prostaglandin. Although NSAIDs have analgesic effects, the mechanism of action in dysmenorrhea is most likely the antiprostaglandin effect.
