HESI RN

Reproductive Health Exam

1. At 16 weeks of pregnancy, the breast changes include:

A. Montgomery's tubercles are prominent.
B. Darkening of the nipple.
C. Prickling, tingling sensation.
D. Colostrum can be expressed.

Correct answer: C

Rationale: At 16 weeks of pregnancy, the sensation of prickling and tingling in the breasts is common due to hormonal changes. Montgomery's tubercles becoming prominent is more characteristic of early pregnancy, typically around the first trimester. Darkening of the nipple, known as areola darkening, can occur but is more commonly observed later in pregnancy. The expression of colostrum, the first milk produced by the mammary glands, usually happens closer to the end of pregnancy or after childbirth, not typically at 16 weeks.

2. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
B. Blood volume and plasma volume decrease, and red blood cells decrease.
C. No changes occur in the haematological system during pregnancy.
D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.

3. In 1989, the national population policy was formally launched targeting:

A. Reducing population growth
B. Making family planning services available
C. Making services accessible and affordable to all eligible users
D. All of the above

Correct answer: D

Rationale: The correct answer is D because the national population policy launched in 1989 aimed at reducing population growth by making family planning services available, accessible, and affordable to all eligible users. Choice A is incorrect as it does not encompass the full scope of the policy objectives. Choice B is also incomplete as it focuses solely on availability without considering accessibility and affordability. Choice C is partially correct but lacks the comprehensive approach of the national population policy.

4. Which one is not a barrier method for birth control?

A. Diaphragms
B. Cervical caps
C. Vaults
D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.

5. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:

A. Ovulation
B. Regenerative
C. Secretory
D. Menstruation

Correct answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.
