Question 2

A nurse is explaining to a nursing student how clomiphene Clomid works to improve fertility. Which statement by the student indicates a need for further teaching?
 
  a. Clomiphene blocks estrogen receptors to cause increased secretion of gonadotro-pins.
  b. Clomiphene directly stimulates the ovary, causing follicular maturation and ovulation.
  c. If follicular maturation is the only result of clomiphene therapy, human chorionic gonadotropin may be given.
  d. If the pituitary gland cannot produce LH and FSH, clomiphene will not be effec-tive.

Answer to Question 1

D
All women of child-bearing age need 400 to 800 mg of synthetic folate in addition to dietary sources to help prevent neural tube defects in the fetus. The bioavailability of synthetic folate is increased in the presence of food. Dietary folate is not sufficient to prevent neural tube defects, even when these foods are consumed in increased amounts. Taking folate on an empty stomach reduces the amount absorbed.

Answer to Question 2

B
Clomiphene blocks receptors for estrogen; it does not directly stimulate the ovary. When estrogen receptors are blocked, the pituitary increases production of the gonadotropins LH and FSH. Clomiphene may produce follicular maturation without ovulation, and hCG will be given to produce ovulation. Without a pituitary capable of producing LH and FSH, clomiphene will not be effective.
