What are possible characteristics of a patient who is at a higher risk for developing uterine cancer?
- A. 35-year-old patient with 2 vaginal births
- B. 16-year-old patient with 28-day menstrual cycle
- C. 67-year old patient taking only estrogen for HRT
- D. 25-year-old patient taking oral contraceptive pills
Correct Answer: C
Rationale: Step-by-step rationale:
1. Uterine cancer risk increases with age, so a 67-year-old patient is at higher risk.
2. Estrogen-only HRT without progesterone increases uterine cancer risk.
3. Other choices are less likely: A has lower age and childbirth may reduce risk, B's age and menstrual cycle are not typical risk factors, and D's oral contraceptives may decrease uterine cancer risk.
What are the factors that explain why a woman is fertile only a few days out of each monthly cycle?
- A. (1) Sperm usually cannot survive in the female reproductive tract for more than a few days, (2) an ovum must unite with a sperm during the first 24 hours after ovulation, before it reaches the uterus, so it will be ready for implantation, and (3) the cyclical mechanisms of female reproductive function limit the release of ova.
- B. (1) Sperm usually cannot survive in the female reproductive tract for more than 24 hours, (2) an ovum must unite with a sperm within the first 12 hours after ovulation, before it reaches the uterus, so it will be ready for implantation, and (3) the cyclical mechanisms of female reproductive function limit the release of ova.

- D. (1) Sperm usually cannot survive in the female reproductive tract for more than 12 hours, (2) an ovum must unite with a sperm immediately after ovulation, before it reaches the uterus, so it will be ready for implantation, and (3) the cyclical mechanisms of female reproductive function limit the release of ova.
