Nokea
Where does the ovum receive the sperm?
- A. Animal pole
- B. Vegetal pole
- C. Zona pellucida
- D. None of the above
Correct Answer: C
Rationale: The correct answer is C: Zona pellucida. The ovum receives the sperm in the zona pellucida, which is a glycoprotein layer surrounding the oocyte. Sperm must first penetrate this layer to fertilize the egg. Choices A and B (Animal pole and Vegetal pole) refer to different regions of the egg and are not directly involved in sperm-egg interaction. Choice D (None of the above) is incorrect because the zona pellucida is indeed where the sperm interacts with the ovum during fertilization.

A client who is scheduled for an endometrial biopsy expresses concerns about the procedure as she is apprehensive of 'being operated' on. How can the nurse relieve her anxiety?
- A. The nurse should inform her that this test will not require her to be under anesthetic influence for a long period.
- B. The nurse should inform her that this test will be performed under general anesthesia and she will be pain free.
- C. The nurse should inform her that this test will be performed under the care of expert physicians and nurses.
- D. The nurse should inform her that this procedure may be performed without anesthesia in the physician's office.

When palpating the epididymis, the nurse considers which finding to be abnormal?
- A. The epididymis is located on the posterolateral surface of each testis.
- B. The epididymis feels like a tubular, comma-shaped structure.
- C. The epididymis collapses on palpation.
- D. The epididymis has an irregular, nodular surface.
Correct Answer: D
Rationale: The correct answer is D because an epididymis with an irregular, nodular surface is abnormal and may indicate a pathology such as epididymitis or a tumor. Step 1: Normal epididymis should feel smooth and firm, not irregular. Step 2: Nodular surface suggests a growth or inflammation. Step 3: Abnormal findings should prompt further evaluation. Incorrect choices: A is correct anatomical location, B describes the normal shape, and C collapsing is not a typical finding.
Mammary papilla means the;
- A. Areola
- B. Lactiferous duct
- C. Sinuses
- D. Nipple
Correct Answer: D
Rationale: The correct answer is D: Nipple. The mammary papilla refers to the nipple, the protruding part of the breast where milk is released during breastfeeding. It is the anatomical structure that connects the lactiferous ducts to the outside of the body. The other choices are incorrect because:
A: Areola is the darker area surrounding the nipple.
B: Lactiferous duct is the tube that carries milk from the mammary glands to the nipple.
C: Sinuses are not directly related to the mammary papilla.
In teaching a class of adolescents about sexually transmitted diseases, a nurse includes which information about the human papillomavirus (HPV)?
- A. HPV is fragile and not easily transmitted.
- B. Wartlike growths in the genital area are a sign of HPV infection.
- C. There is a specific blood test needed to screen for HPV.
- D. Heavy, purulent vaginal discharge is the primary sign of HPV.
Correct Answer: B
Rationale: The correct answer is B: Wartlike growths in the genital area are a sign of HPV infection. This is because HPV often manifests as genital warts. HPV is a common sexually transmitted infection that can lead to various health issues, including genital warts and certain types of cancers. Choices A, C, and D are incorrect because HPV is not fragile, does not require a specific blood test for screening, and does not typically present with heavy, purulent vaginal discharge.
The _____ is the space between the labia minor.
- A. vulva
- B. vestibule
- C. vaginal orifice
- D. pudendal cleft
Correct Answer: B
Rationale: The correct answer is B: vestibule. The vestibule is the space between the labia minora, housing the openings of the urethra and vagina. It is a specific anatomical term that describes this precise area. The other choices, A: vulva refers to the external female genitalia as a whole, C: vaginal orifice specifically denotes the opening of the vagina, and D: pudendal cleft is a term not commonly used in anatomy to describe this specific space. Therefore, B is the correct answer as it accurately describes the anatomical structure in question.
