The nurse explains to a patient being prepared for colposcopy with a cervical biopsy that the procedure

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.

Correct Answer: C

Rationale: The correct answer is C: Seminiferous tubules. Spermatogenesis is the process of sperm production, which occurs in the seminiferous tubules of the testes. These tubules contain specialized cells called Sertoli cells and spermatogonia that undergo multiple stages of cell division and maturation to form spermatozoa. Interstitial cells (A) produce testosterone, seminal vesicles (B) secrete seminal fluid, and vas deferens (D) is the duct that carries sperm from the testes to the urethra but is not the site of spermatogenesis.

Correct Answer: A

Rationale: Correct Answer: A - Sister chromatids may no longer be identical to each other. Rationale: 1. In metaphase II, sister chromatids align at the metaphase plate. 2. During meiosis II, sister chromatids separate and move to opposite poles. 3. Due to potential crossing over in meiosis I, sister chromatids may not be identical in meiosis II. 4. This variability contributes to genetic diversity in the resulting gametes. Summary: B: Homologous chromosomes do not line up in metaphase II; they already separated in meiosis I. C: Crossing over occurs in meiosis I, not in meiosis II. D: Homologous chromosomes start to separate in anaphase I, not metaphase II.

Correct Answer: A

Rationale: The correct answer is A because milk production is indeed controlled by prolactin, a hormone secreted by the anterior pituitary gland. Prolactin stimulates the alveoli in the breast to produce milk. Option B is incorrect because estrogen and prolactin actually work synergistically to promote lactation. Option C is incorrect as the nipple is lubricated by Montgomery glands, not sebaceous glands. Option D is incorrect because myoepithelial cell contraction helps in milk ejection, not in milk production.

Correct Answer: B

Rationale: The correct answer is B, slight chills and fever. This finding may indicate an infection, which can be a serious complication post-endometrial biopsy. Fever and chills can be signs of systemic infection, requiring immediate medical attention to prevent further complications. Mild cramping (A) is a common post-procedure symptom. Spotting of blood (C) is also normal after an endometrial biopsy. Fatigue (D) after anesthesia is expected and not an immediate concern unless severe or persistent.
