basal body temperature rise of is seen in the luteal phase due to thermogenic effects of a metabolite of progesterone in a normal cycle

HESI RN

Reproductive Health Exam

1. Basal body temperature rise of _____ is seen in the luteal phase due to the thermogenic effects of a metabolite of progesterone in a normal cycle:

A. 0.1-0.5
B. 0.2-0.5
C. 1.0-2.0
D. 1.5-2.0

Correct answer: B

Rationale: A basal body temperature rise of 0.2-0.5 degrees Celsius is typically seen in the luteal phase of the menstrual cycle due to the thermogenic effects of a metabolite of progesterone. This temperature rise helps to indicate ovulation has occurred. Choices A, C, and D are incorrect as they do not reflect the usual range of temperature increase observed during the luteal phase. A rise of 0.1-0.5 degrees Celsius is too narrow (eliminating choice A), while ranges of 1.0-2.0 and 1.5-2.0 degrees Celsius are too high and not consistent with the expected basal body temperature changes during the menstrual cycle.

2. A woman is considered to be in menopause if she has experienced the cessation of her menses for a period of:

A. 6 months
B. 12 months
C. 18 months
D. 24 months

Correct answer: B

Rationale: Menopause is defined as the cessation of menses for 12 months. This period is significant because it indicates the end of a woman's reproductive years. Choices A, C, and D are incorrect as they do not align with the established criteria for defining menopause.

3. Which of the following is NOT a phase of the menstrual cycle?

A. Follicular phase
B. Ovulatory phase
C. Luteal phase
D. Secretory phase

Correct answer: D

Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.

4. How can menopause affect health?

A. Causing conjunctivitis
B. Leading to colitis or bowel upsets
C. Increasing the risk of cancer
D. Triggering urinary infections

Correct answer: D

Rationale: Menopause can lead to changes in the urinary tract, such as decreased estrogen levels, which can increase the likelihood of urinary tract infections. While menopause can impact various aspects of health, including bone density and heart health, it is not directly linked to conjunctivitis, colitis, or an increased risk of cancer. Therefore, the correct answer is D.

5. _______ is a lytic enzyme released by the sperm.

A. Hyaluronidase
B. Trypsin
C. Helicase
D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.
