Seminiferous tubules are lined with:
- A. Oocytes
- B. red blood cells
- C. Leydig cells
- D. Sertoli cells
Correct Answer: D
Rationale: The correct answer is D: Sertoli cells. Seminiferous tubules are lined with Sertoli cells, which provide structural support and nourishment to developing sperm cells. These cells also help in the process of spermatogenesis.
A: Oocytes are female germ cells found in the ovaries, not in the seminiferous tubules.
B: Red blood cells are not found in the seminiferous tubules. They are responsible for carrying oxygen in the bloodstream.
C: Leydig cells are found in the interstitial tissue of the testes and are responsible for producing testosterone, not lining the seminiferous tubules.
Therefore, the correct choice is D as Sertoli cells play a crucial role in sperm production within the seminiferous tubules.

Soft spots that refers to unossified areas in an infants skull is termed as
- A. Sulcus
- B. Sinus
- C. Fontanelle
- D. Suture
Correct Answer: C
Rationale: The correct answer is C: Fontanelle. Fontanelles are soft spots in an infant's skull where the bones have not yet fully fused. They allow for the baby's brain to grow and accommodate the rapid brain development during the early months of life. Sulcus refers to a groove or furrow, sinus is a cavity within a bone, and suture is the line where two bones meet. These terms do not specifically refer to the unossified areas in an infant's skull, making them incorrect choices.
The ovary is located in the:
- A. abdominal cavity;
- B. pelvic cavity;
- C. inguinal region;
- D. lumbar region;
Correct Answer: B
Rationale: The correct answer is B: pelvic cavity. The ovary is located in the pelvic cavity because it is part of the female reproductive system and is situated within the pelvis. It is specifically housed in the adnexal region of the pelvis, attached to the uterus via ligaments. The abdominal cavity (choice A) is too high up in the body to house the ovary. The inguinal region (choice C) is located in the lower abdomen near the groin and does not contain the ovary. The lumbar region (choice D) is located in the lower back and is not where the ovary is located.
The 16 feet long tube that is coiled and located above the
- A. epididymis
- B. Vas deferens
- C. Urethra
- D. Ureter
Correct Answer: A
Rationale: The correct answer is A: epididymis. The epididymis is a coiled tube located on the back of each testicle, approximately 16 feet long when unraveled. It plays a crucial role in sperm maturation and storage. The other choices, B: Vas deferens, C: Urethra, and D: Ureter, are incorrect as they are not coiled tubes located above the testicles and do not have the same function as the epididymis in sperm development and storage.
A 19-yr-old patient calls the school clinic and tells the nurse, “My menstrual period is very heavy this time. I have to change my tampon every 4 hours.” Which action should the nurse take next?
- A. Tell the patient that her flow is not unusually heavy.
- B. Schedule the patient for an appointment later that day.
- C. Ask the patient how heavy her usual menstrual flow is.
- D. Have the patient call again if the heavy flow continues.
Correct Answer: C
Rationale: The correct answer is C: Ask the patient how heavy her usual menstrual flow is. This is the best course of action as it allows the nurse to gather more information about the patient's menstrual history and determine if the current heavy flow is a deviation from her normal pattern. By obtaining information on the patient's usual menstrual flow, the nurse can assess if the current situation warrants further evaluation or if it falls within the range of normal variability.
Choice A is incorrect because dismissing the patient's concern without further assessment may lead to missing a potential issue. Choice B is not the best immediate action as it does not prioritize gathering more information first. Choice D is also not the optimal choice as it does not address the need for more information to assess the situation accurately.
