Question 4

After reading the paragraph below, answer the question(s) that follow(s).
Sarah is a 40-year-old woman. She understands that the quality of her eggs has declined markedly since she was about 35. However, she also is aware that the ability of the rest of the female reproductive system to carry out a successful pregnancy resulting in the birth of a normal healthy child is not nearly so sensitive to age.
-Of the following options, which is the only one that would not be available to Sarah if she wishes to increase the likelihood of having a child?

Accepted Answer

A)  use her own eggs that she had harvested and frozen when she was 25 
B)  use a donor egg from a 25-year-old woman 
C)  have many of her own eggs harvested and fertilized and then choose the best ones for implantation 
D)  use sperm from a very young male to fertilize her eggs, so that the average age of her eggs and the sperm would be lower

Question 5

After reading the paragraph below, answer the question(s) that follow(s).
Billy is 8 years old and occasionally experiences nocturnal enuresis, more commonly known as 'bedwetting.' He likes to sleep over at his friend's house, but is embarrassed to 'have an accident.' To address this concern, he has been prescribed a nasal spray medication that reduces the rate of urine formation. If he takes this medication it reduces the likelihood of bedwetting. The active ingredient of the medication is a hormone.
-What hormone would likely be in Billy's medication?

Accepted Answer

A)  prolactin 
B)  thyroxine 
C)  ADH 
D)  thyroid stimulating hormone (TSH) 
A)  prolactin 
B)  thyroxine 
C)  ADH 
D)  thyroid stimulating hormone (TSH)

Question 6

The active ingredient of the medication is a hormone.
-How would the hormone work?

Accepted Answer

A)  It would stimulate water loss through perspiration rather than urination. 
B)  It would stimulate water retention in the body. 
C)  It would reduce water formation in the body. 
D)  It would reduce overall kidney activity.

B)  reduced ribosomal activity and therefore protein synthesis 
C)  changes in membrane composition 
D)  altered mitochondrial function leading to compromised cellular energetics
