Sperm maturation occurs in the
- A. seminiferous tubules
- B. epididymis
- C. vas deferens
- D. urethra
Correct Answer: B
Rationale: The correct answer is B: epididymis. Sperm maturation occurs in the epididymis, a coiled tube located on the posterior surface of the testes. Here, sperm undergo the process of capacitation, gaining the ability to fertilize an egg. The seminiferous tubules (choice A) are responsible for sperm production, not maturation. The vas deferens (choice C) is a duct that carries mature sperm from the epididymis to the urethra, and the urethra (choice D) is a passage for both urine and sperm but not the site of sperm maturation.

Benign tumors originating in the myometrium are
- A. Fibroids
- B. Rhabdomyoma
- C. Leiomyoma
- D. Both a & c
Correct Answer: D
Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
The nurse explains to a patient being prepared for colposcopy with a cervical biopsy that the procedure
- A. involves dilation of the cervix and biopsy of the tissue lining the uterus.
- B. will take place in a same-day surgery center so that local anesthesia can be used.
- C. requires that the patient have nothing to eat or drink for 6 hours before the procedure.
- D. Is similar to a speculum examination of the cervix and should result in little
Correct Answer: A
Rationale: Step 1: Colposcopy with a cervical biopsy involves visualization of the cervix using a colposcope.
Step 2: The procedure may involve taking a biopsy of abnormal tissue for further evaluation.
Step 3: Dilation of the cervix may be needed to access and obtain a biopsy sample.
Step 4: Biopsy is taken from the tissue lining the cervix, not the uterus.
Step 5: Therefore, option A is correct as it accurately describes the procedure.
Summary: Choice B is incorrect as colposcopy can be performed in an outpatient setting without the need for local anesthesia. Choice C is incorrect as fasting is not typically required for this procedure. Choice D is incorrect as colposcopy is more invasive than a speculum examination.
The testosterone secretion is controlled by:
- A. the FSH;
- B. the LH;
- C. the corticoadrenal;
- D. the negative feedback of posterior pituitary;
Correct Answer: B
Rationale: Step 1: LH (luteinizing hormone) is produced by the pituitary gland and plays a key role in stimulating the Leydig cells in the testes to produce testosterone.
Step 2: Testosterone secretion is directly controlled by the LH through this stimulation.
Step 3: FSH (follicle-stimulating hormone) is involved in sperm production, not testosterone secretion.
Step 4: Corticoadrenal hormones are related to stress response, not testosterone regulation.
Step 5: Negative feedback from the posterior pituitary does not directly control testosterone secretion.
Therefore, the correct answer is B (the LH) as it directly influences testosterone production.
Bones that are fused across the joint space by surgery is termed as
- A. Ankylosis
- B. Arthrodesis
- C. Arthroplasty
- D. Arthroscopy
Correct Answer: B
Rationale: The correct answer is B: Arthrodesis. Arthrodesis refers to the surgical fusion of bones across a joint space. This procedure aims to stabilize a joint by creating a bony union. Ankylosis (A) is the natural fusion of bones due to disease or injury. Arthroplasty (C) involves replacing a damaged joint with an artificial prosthesis. Arthroscopy (D) is a minimally invasive procedure to visualize and treat joint problems without open surgery. In this context, only arthrodesis specifically involves fusing bones across a joint space.
The mother of an 18-year-old girl asks the nurse which screening her daughter should receive now based on evidence-based recommendations. Which suggestion by the nurse is best?
- A. Papanicolaou test
- B. Human papilloma virus (HPV) test
- C. Mammogram
- D. No screenings at this time
Correct Answer: D
Rationale: The correct answer is D because evidence-based recommendations do not support routine screening for cervical cancer (Papanicolaou test) or breast cancer (mammogram) in asymptomatic individuals under 21. HPV test is not recommended as a standalone screening for young women. No screenings at this time aligns with current guidelines to avoid unnecessary testing and potential harm in low-risk populations. It's important to focus on preventive measures such as vaccinations and healthy lifestyle choices rather than invasive screenings for this age group.
