Shin bone is also known as
- A. Femur
- B. Tibia
- C. Fibula
- D. Patella
Correct Answer: B
Rationale: The correct answer is B: Tibia. The shin bone is commonly referred to as the tibia. This bone is located on the inner side of the leg and is the larger of the two lower leg bones. The femur (A) is the thigh bone, the fibula (C) is the smaller of the two lower leg bones, and the patella (D) is the kneecap. Therefore, the tibia is the correct answer as it specifically refers to the shin bone.

About the Fallopian tubes we can state the following:
- A. are funnel-shaped, with edges flared towards the uterus;
- B. the medial extremity displays flares;
- C. it is linked to the uterus through the uterine ostium;
- D. the lateral extremity opens in the abdominal cavity;
Correct Answer: A
Rationale: The correct answer is A because Fallopian tubes are indeed funnel-shaped, with edges flared towards the uterus. This shape helps capture the released egg from the ovary and guide it towards the uterus for potential fertilization. The other choices are incorrect because the medial extremity does not display flares (B), the Fallopian tube is not directly linked to the uterus through the uterine ostium (C), and the lateral extremity does not open in the abdominal cavity (D). Therefore, choice A is the most accurate description of the Fallopian tubes based on their anatomy and function.
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.
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.
As menstruation ends estrogen levels in the blood rise rapidly. What is the source of the estrogen?
- A. Corpus luteum
- B. Developing follicles
- C. Endometrium
- D. Stromal cells of the ovaries
Correct Answer: B
Rationale: The correct answer is B: Developing follicles. After menstruation, the developing follicles in the ovaries produce estrogen. This estrogen is responsible for thickening the endometrium in preparation for potential implantation of a fertilized egg. The corpus luteum produces progesterone, not estrogen. The endometrium is the inner lining of the uterus and is not a direct source of estrogen. Stromal cells of the ovaries are supportive cells and do not produce estrogen.
Which of the following characterizes the secretory phase of a female's uterine (menstrual) cycle?
- A. Ovulation of a secondary oocyte occurs.
- B. The functional layer of the endometrium is absent.
- C. The corpus luteum increases progesterone levels.
- D. The functional layer of the endometrium is she
Correct Answer: C
Rationale: The secretory phase follows ovulation in the menstrual cycle. During this phase, the corpus luteum, formed from the ruptured follicle, secretes progesterone, maintaining the endometrium for potential implantation of a fertilized egg. Choice A is incorrect as ovulation occurs in the preceding phase (ovulatory phase). Choice B is incorrect as the functional layer of the endometrium thickens during the secretory phase to support a potential pregnancy. Choice D is incorrect as the functional layer of the endometrium is not shed during the secretory phase, but rather maintained for pregnancy support.
