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.

Connective tissue fibers include:
- A. Purkinje, elastic and reticular fibers
- B. Purkinje, elastic and collagen fibers
- C. Reticular, elastic and collagen fibers
- D. Purkinje, reticular and collagen fibers
Correct Answer: C
Rationale: The correct answer is C: Reticular, elastic, and collagen fibers. Reticular fibers provide structural support, elastic fibers allow flexibility, and collagen fibers offer strength to connective tissues. Purkinje fibers are specialized cardiac muscle fibers, not connective tissue fibers. Choice A is incorrect because it includes Purkinje fibers, which are not part of connective tissue. Choice B is incorrect as it includes Purkinje fibers instead of reticular fibers. Choice D is incorrect because it lacks elastic fibers, which are essential for tissue flexibility. Therefore, choice C is the correct answer as it includes all three types of essential connective tissue fibers.
