The nurse is speaking with a couple trying to conceive a child. What will the nurse remind the couple is a factor that can decrease sperm production?
The testes being too warm
The penis and testes being small
Infrequent sexual intercourse
The man not being circumcised
The Correct Answer is A
A. Sperm production is temperature-sensitive, and the testes require a slightly cooler environment than the rest of the body. Increased warmth, such as from tight clothing, prolonged sitting, or heat exposure, can impair spermatogenesis.
B. The size of the penis and testes is not directly correlated with sperm production. The functionality of the testes, not their size, determines sperm output.
C. Infrequent sexual intercourse can affect fertility by decreasing opportunities for conception but does not directly decrease sperm production.
D. Circumcision status does not affect sperm production, as it primarily pertains to hygiene and the prevention of certain infections.

Correct Answer is C
Explanation
A. Prior to giving birth: Live vaccines, such as MMR, are contraindicated during pregnancy due to the risk of harm to the fetus.
B. Two weeks before attempting pregnancy again: After receiving the MMR vaccine, a woman should wait at least 1 month (not 2 weeks) before attempting conception to prevent fetal exposure to the live virus.
C. When she does not desire future pregnancies: This would unnecessarily delay protection against rubella, which could pose a risk in future exposures or pregnancies.
D. Prior to discharge from the hospital after giving birth: This is the correct time to administer the MMR vaccine. It ensures the woman receives immunity before leaving the hospital and protects future pregnancies from congenital rubella syndrome.
Correct Answer is B
Explanation
A. Possible signs of pregnancy are not a recognized classification in obstetrics; signs are categorized as presumptive, probable, or positive.
B. Feeling fetal movement, or quickening, is a presumptive sign of pregnancy because it is subjective and can be influenced by other factors, such as gastrointestinal activity or perception errors.
C. Probable signs are objective findings observed by a healthcare provider, such as a positive pregnancy test or uterine enlargement, not based on the woman's report.
D. Positive signs of pregnancy are definitive and include visualizing the fetus on ultrasound or hearing the fetal heartbeat through Doppler, neither of which relies on subjective feelings.
