Nursing Elites

1. What is the most common site for an ectopic pregnancy?

• A. Isthmus
• B. Ampulla
• C. Interstitial
• D. Infundibulum

Correct answer: C

Rationale: The correct answer is C, Interstitial. An ectopic pregnancy most commonly occurs in the interstitial portion of the fallopian tube. This is because the interstitial part is narrow and not suitable for the growing embryo, leading to implantation outside the uterus. Choices A, B, and D are incorrect because although ectopic pregnancies can occur in various locations, the interstitial portion of the fallopian tube is the most frequent site for such pregnancies.

2. During an ectopic pregnancy, what is the likelihood of a rupture in the ampullary portion of the tube?

• A. Frequent
• B. Uncommon
• C. Occasional
• D. Never

Correct answer: A

Rationale: During an ectopic pregnancy, a rupture in the ampullary portion of the tube is frequent. This is due to the increased pressure within the fallopian tube as the embryo grows, leading to the rupture of the tube. Choices B, C, and D are incorrect as they do not accurately describe the common occurrence of rupture in this specific part of the tube during an ectopic pregnancy.

3. 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.

4. What is the triangular space lying between the vaginal and rectal canals?

• A. Pelvic floor
• B. Perineum
• C. Vestibule
• D. Perineal body

Correct answer: B

Rationale: The correct answer is B: Perineum. The perineum is the triangular space located between the vaginal and rectal canals. It is a region containing various muscles, nerves, and blood vessels that support the pelvic floor. Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.

5. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

Correct answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.
