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. According to the Medical Termination of Pregnancy (MTP) Act, 1971, how many weeks of pregnancy is Medical Termination of Pregnancy considered safe up to?

A. 8 Weeks
B. 12 Weeks
C. 18 Weeks
D. 6 Weeks

Correct answer: B

Rationale: According to the Medical Termination of Pregnancy (MTP) Act, 1971, Medical Termination of Pregnancy is considered safe up to 12 weeks of pregnancy. This timeframe is crucial to ensure the safety and well-being of the individual undergoing the procedure. Choices A, C, and D are incorrect because they do not align with the legal provisions outlined in the MTP Act, 1971.

3. What causes the changes in appearance seen in boys at the time of puberty?

A. Prolactin
B. Adrenaline
C. Estrogen
D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. Which of the following is a function of the placenta?

A. The placenta secretes insulin.
B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
C. The placenta provides immunological protection to the fetus.
D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

5. Which one of the following is not associated with poor maternal outcome?

A. APH
B. PPH
C. Cord prolapse
D. Pre-eclampsia

Correct answer: C

Rationale: Cord prolapse is not typically associated with poor maternal outcomes. Acute placental hemorrhage (APH - choice A) and postpartum hemorrhage (PPH - choice B) can lead to maternal morbidity and mortality due to excessive blood loss. Pre-eclampsia (choice D) is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, which can result in severe maternal complications if not managed promptly. Cord prolapse, though concerning for fetal well-being, does not inherently pose direct risks to maternal health if managed appropriately, making it the correct answer in this context.
