b. It is important to have someone else change the litter pan during pregnancy and also avoid consuming raw vegetables.
c. Have you had any flu-like symptoms since you got your cat? If so, you may have already had toxoplasmosis and there is nothing to worry about.

Answer to Question 1

ANS: a
Feedback
a. Spermatogenesis occurs in the testes. High temperatures harm the development of the sperm.
b. When the vas deferens is ligated, a man has had a vasectomy and is sterile. The sterility is not due to impaired spermatogenesis, but rather to the inability of the sperm to migrate to the woman's reproductive track.
c. The enlarged prostrate has no effect on spermatogenesis.
d. The flagella are the tails of the sperm. They are normally divided into the middle segment and an end segment.

Answer to Question 2

ANS: d
Feedback
a. The nurse should also explain that the patient should not eat uncooked meat as it is a potential source for toxoplasmosis.
b. Raw vegetables are not a source for toxoplasmosis.
c. This is not an accurate way to diagnose if the woman has had toxoplasmosis.
d. Women need to be aware that Toxoplasma gondii, a single-celled parasite, is responsible for the infection toxoplasmosis. The majority of individuals who become infected with toxoplasmosis are asymptomatic, although when present, symptoms are described as flu like and include glandular pain and enlargement and myalgia. Severe toxoplasmosis infection may cause damage to the fetal brain, eyes, or other organs. Toxoplasmosis is usually acquired by consuming raw or poorly cooked meat that has been contaminated with T. gondii. Toxoplasmosis may also be acquired through close contact with feces from an infected animal (usually cats) or soil that has been contaminated with T. gondii.
