The uterine artery vascularizes:
- A. the vagina;
- B. the Fallopian tubes;
- C. the uterus;
- D. the vulva;
Correct Answer: C
Rationale: The correct answer is C: the uterus. The uterine artery vascularizes the uterus, providing the main blood supply to this reproductive organ. This artery plays a crucial role in supplying oxygen and nutrients to the uterus, supporting the growth and development of the endometrium and the fetus during pregnancy.
Choice A, the vagina, is incorrect because the vaginal artery, not the uterine artery, supplies blood to the vagina. Choice B, the Fallopian tubes, is incorrect as they are primarily vascularized by the tubal branches of the ovarian arteries. Choice D, the vulva, is also incorrect as the blood supply to the vulva comes from multiple sources including the internal pudendal artery and the external pudendal artery, not the uterine artery.

While you are orienting a new RN to the medical-surgical unit, you observe the orientee accomplishing all of the following actions while caring for a client with severe pelvic inflammatory disease (PID), who has been admitted to the hospital for administration of IV antibiotics. Which one will require that you intervene most quickly?
- A. The new RN tells the client she should avoid using tampons in the future.
- B. The new RN offers the client an ice pack to decrease her abdominal pain.
- C. The new RN positions the client flat in bed while helping her take a bath.
- D. The new RN teaches the client she should not have intercourse for 2 months.
Correct Answer: C
Rationale: Positioning the client flat in bed can exacerbate discomfort and is inappropriate for PID.
Outermost layer of the uterus is
- A. Peritoneum
- B. Pericardium
- C. Perimetrium
- D. Pericyte
Correct Answer: C
Rationale: The correct answer is C: Perimetrium. The perimetrium is the outermost layer of the uterus and consists of a thin serous layer of connective tissue. This layer provides support and protection to the uterus.
Rationale:
1. Peritoneum (A) is the serous membrane that lines the abdominal cavity, not the outermost layer of the uterus.
2. Pericardium (B) is the membranous sac that surrounds the heart, not related to the uterus.
3. Pericyte (D) is a type of cell found in blood vessels and involved in vascular function, not a layer of the uterus.
In summary, the perimetrium is the correct answer as it is the specific layer that forms the outer covering of the uterus, providing structural support and protection.
Which question should the nurse ask when assessing a 60-yr-old patient who has a history of benign prostatic hyperplasia (BPH)?
- A. “Have you noticed any unusual discharge from your penis?”
- B. “Has there been any change in your sex life in the past year?”
- C. “Has there been a decrease in the force of your urinary stream?”
- D. “Have you been experiencing any difficulty in achieving an erection?”
Correct Answer: C
Rationale: The correct question to ask when assessing a 60-yr-old patient with a history of BPH is C: “Has there been a decrease in the force of your urinary stream?” This question is relevant as BPH commonly causes urinary symptoms like weak urinary stream. Asking about unusual discharge (A) is more relevant for assessing sexually transmitted infections. Inquiring about changes in sex life (B) and difficulty achieving an erection (D) are more related to erectile dysfunction, which may not be directly linked to BPH in this context.
A cell called the ______ is a fertilized cell with 46 chromosomes.
- A. spermatozoon
- B. polar body
- C. ovum
- D. zygote
Correct Answer: D
Rationale: The correct answer is D: zygote. A zygote is formed when a sperm cell fertilizes an egg cell, resulting in a single cell with a full set of 46 chromosomes. This process is called fertilization and marks the beginning of a new individual. The other choices (A: spermatozoon, B: polar body, C: ovum) are not correct because a spermatozoon is a mature sperm cell with 23 chromosomes, a polar body is a byproduct of meiosis in the female reproductive system and has only 23 chromosomes, and an ovum is an unfertilized egg cell also containing 23 chromosomes.
With respect to Sertoli cells which of the following statements is incorrect
- A. Nourish developing sperm
- B. receive stimulation by testosterone
- C. phagocytose defective sperm
- D. secrete the hormone inhibin which inhibits luteinizing hormone secretion
Correct Answer: D
Rationale: The correct answer is D because Sertoli cells do secrete inhibin, but it does not inhibit luteinizing hormone secretion. Inhibin actually inhibits follicle-stimulating hormone (FSH) secretion. Sertoli cells support spermatogenesis by nourishing developing sperm (A), they are stimulated by testosterone (B), and they also phagocytose defective sperm (C). Therefore, option D is incorrect as it misrepresents the role of inhibin in the endocrine regulation of the male reproductive system.
