HESI RN

Reproductive Health Exam

1. Discuss the anatomical/physiological changes in pregnancy under the following: Kidney/renal system

A. Kidneys increase in size, pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases.
B. Kidneys decrease in size, and glomerular filtration rate decreases.
C. There is no change in kidney size or ureter function, but the glomerular filtration rate decreases.
D. Kidneys shrink, and ureters remain the same.

Correct answer: A

Rationale: During pregnancy, the kidneys increase in size, the pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases. This is due to the increased metabolic demands and hormonal changes during pregnancy. Choice B is incorrect as the kidneys do not decrease in size, and the glomerular filtration rate actually increases. Choice C is incorrect as there are changes in kidney size and ureter function during pregnancy. Choice D is incorrect as the kidneys do not shrink during pregnancy.

2. At what point is a fetus considered viable?

A. 26 weeks
B. 28 weeks
C. 37 weeks
D. 12 weeks

Correct answer: C

Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.

3. At 6-8 weeks of pregnancy, the breast changes include:

A. Colostrum can be expressed.
B. Breasts become tender.
C. Montgomery's tubercles are prominent.
D. Nipples become prominent and mobile.

Correct answer: C

Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.

4. During fertilization, the portion of the decidua covering the blastocyst is called:

A. Decidua basalis
B. Decidua Vera
C. Decidua parietalis
D. Decidua capsularis

Correct answer: D

Rationale: During fertilization, the decidua capsularis is the specific portion of the decidua that covers the blastocyst, providing protection and support. Decidua basalis refers to the part of the decidua located at the site of implantation on the maternal side. Decidua vera is the remainder of the decidua lining the uterus. Decidua parietalis is the portion of the decidua that lines the rest of the uterine cavity, except for the site of implantation. Therefore, in the context of fertilization, the decidua capsularis is the correct answer.
