The testicle vascularization:
- A. the arterial one is provided by the gonadal artery, a branch off the abdominal aorta;
- B. the venous one is tributary to the internal iliac vein;
- C. the arterial one is provided by the testicular artery, a branch off the internal iliac artery;
- D. the venous one is tributary to the inferior vena cava;
Correct Answer: A
Rationale: The correct answer is A because the arterial vascularization of the testicle is indeed provided by the gonadal artery, which is a branch off the abdominal aorta. This is anatomically accurate as the gonadal artery supplies blood to the testicles.
Choice B is incorrect because the venous drainage of the testicle is to the testicular vein, which drains into the inferior vena cava, not the internal iliac vein as stated in option B.
Choice C is incorrect because the testicular artery, not the internal iliac artery, is responsible for the arterial supply to the testicle.
Choice D is incorrect because the venous drainage of the testicle is not tributary to the inferior vena cava; instead, it drains into the left renal vein.

The ________________ is a muscular organ that is situated between the bladder and the rectum
- A. Vagina
- B. Uterus
- C. Vulva
- D. Ovary
Correct Answer: B
Rationale: The correct answer is B: Uterus. The uterus is a muscular organ located between the bladder and rectum. It plays a crucial role in pregnancy by nurturing and supporting the developing fetus. The other choices (A: Vagina, C: Vulva, D: Ovary) are incorrect because the vagina is a canal leading to the uterus, the vulva is the external genitalia, and the ovary is responsible for producing eggs and hormones. Therefore, the correct answer is the uterus based on its anatomical location and function in the reproductive system.
Spermatogenesis:
- A. occurs in several stages;
- B. includes stages of meiosis I;
- C. includes stages of meiosis II;
- D. it is stimulated by the FSH;
Correct Answer: A
Rationale: Correct Answer: A
Rationale: Spermatogenesis is a complex process involving several stages such as mitosis, meiosis, and maturation. It starts with the division of spermatogonia through mitosis, followed by meiosis I and II to form haploid spermatids. These spermatids then undergo maturation to become spermatozoa. Therefore, spermatogenesis occurs in several stages, making choice A the correct answer.
Summary of Incorrect Choices:
B: While spermatogenesis does involve meiosis, it includes both meiosis I and II, not just meiosis I.
C: Spermatogenesis includes both meiosis I and II, not just meiosis II.
D: Spermatogenesis is primarily regulated by hormones such as testosterone and LH, not FSH.
Which portion of the sperm houses the nucleus and its DNA?
- A. Midpiece
- B. Flagellum
- C. Head
- D. Tail
Correct Answer: C
Rationale: The correct answer is C: Head. The head of the sperm contains the nucleus, which houses the DNA. The nucleus carries the genetic information required for fertilization. The midpiece contains mitochondria for energy production, the flagellum provides motility, and the tail is a part of the flagellum. Therefore, the head is the only part of the sperm that houses the nucleus and DNA, making it the correct answer.
The nurse is reviewing discharge plans with a client who is recovering from a cervical biopsy. Which statements indicate good understanding by the client? (Select all that apply.)
- A. “I can return to work this afternoon.”
- B. “I cannot carry my toddler for 2 weeks.”
- C. “I cannot douche until the biopsy site is healed
- D. “I need to wait for about 2 weeks to have intercourse
Correct Answer: B
Rationale: Correct Answer: B
Rationale: The client understanding that they cannot carry their toddler for 2 weeks after a cervical biopsy is crucial to avoid strain and potential complications. Lifting heavy objects can place stress on the biopsy site, leading to bleeding or infection. This restriction promotes proper healing and reduces the risk of complications.
Summary:
A: Returning to work immediately may not allow sufficient time for recovery and could lead to complications.
C: Douching can introduce bacteria to the biopsy site, increasing the risk of infection.
D: Waiting for about 2 weeks before having intercourse is important to prevent trauma to the biopsy site.
Inflammation of joints
- A. Arthritis
- B. Osteomyelitis
- C. Chondritis
- D. Chondritis
Correct Answer: A
Rationale: The correct answer is A: Arthritis. Arthritis specifically refers to inflammation of joints, making it the most appropriate choice. Osteomyelitis (B) is an infection of the bone, not joints. Chondritis (C) is inflammation of cartilage, not joints. The duplicate choice of Chondritis (D) is incorrect.
