The chromosomal disorder CORRECTLY matched with its karyotype is:
- A. Turner’s syndrome – 45X0
- B. Klinefelter’s syndrome – XYY
- C. Patau’s syndrome – Trisomy 21
- D. Edward’s syndrome – Trisomy 13
Correct Answer: A
Rationale: Step-by-step rationale:
1. Turner's syndrome is characterized by a missing X chromosome, resulting in a karyotype of 45X0.
2. Klinefelter's syndrome involves an extra X chromosome, leading to a karyotype of 47XXY.
3. Patau's syndrome is Trisomy 13, not Trisomy 21.
4. Edward's syndrome is Trisomy 18, not Trisomy 13.
Therefore, the correct answer is A because Turner's syndrome is correctly matched with a karyotype of 45X0.

A newly pregnant patient asks the nurse, What is a false pelvis? Which statement by the nurse will best explain this anatomy to the patient?
- A. It is the total anterior portion of the pelvis.
- B. It is considered to be the lower portion of the pelvis.
- C. It provides support for the internal organs and the upper part of the body.
- D. It is the narrowest part of the pelvis through which a fetus will pass during birth.
Correct Answer: C
Rationale: The correct answer is C because the false pelvis, also known as the greater pelvis, is the upper portion of the pelvis that supports the abdominal organs and the weight of the upper body. It is not involved in childbirth.
A: Incorrect. The false pelvis is not the total anterior portion of the pelvis.
B: Incorrect. The false pelvis is not considered the lower portion of the pelvis.
D: Incorrect. The narrowest part of the pelvis through which a fetus passes is the true pelvis, not the false pelvis.

The endometrial thickness is greatest during the:
- A. Secretory phase
- B. Menstrual phase
- C. Proliferative phase
- D. Late follicular phase
Correct Answer: A
Rationale: The correct answer is A: Secretory phase. During the secretory phase of the menstrual cycle, the endometrial thickness is greatest due to increased progesterone levels, leading to thickening of the endometrium in preparation for potential implantation of a fertilized egg. This phase occurs after ovulation and is characterized by glandular secretions and increased vascularity to support a potential pregnancy.
Summary:
- Menstrual phase (B) is incorrect as it is characterized by shedding of the endometrial lining.
- Proliferative phase (C) is incorrect as it involves endometrial thickening but not to the extent seen in the secretory phase.
- Late follicular phase (D) is incorrect as it precedes ovulation and is primarily characterized by follicular development rather than significant endometrial thickening.
