Nokea
The vagina is inserted on the:
- A. uterine corpus;
- B. uterine cervix;
- C. Fallopian tube;
- D. cervix
Correct Answer: D
Rationale: The correct answer is D: cervix. The vagina is inserted on the cervix, which is the lower part of the uterus that connects the uterus to the vagina. The cervix serves as a passageway for sperm to enter the uterus and for menstrual blood to exit. The other choices (A: uterine corpus, B: uterine cervix, C: Fallopian tube) are incorrect because they do not accurately describe the anatomical structure where the vagina is inserted. It is essential to understand the specific anatomical relationships to identify the correct answer.

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.
Which of the following findings would confirm that a female client has mastitis? Choose all that apply.
- A. A crack in the nipple or the areola
- B. Multiple lumps within the breast tissue
- C. Flat and soft breasts
- D. Support the arm and the shoulder with pillows.
Correct Answer: A
Rationale: A crack in the nipple or areola is a common sign of mastitis.
Which of the following is true about placenta?
- A. It produces the hormone hCG.
- B. It stimulates development of the follicle
- C. Implantation site for developing embryo.
- D. It stimulates development of corpus luteum
Correct Answer: A
Rationale: The correct answer is A: It produces the hormone hCG. The placenta is responsible for producing the hormone human chorionic gonadotropin (hCG), which is essential for maintaining pregnancy by supporting the corpus luteum to produce progesterone. This hormone is also detected in pregnancy tests.
Choice B is incorrect because the placenta does not stimulate development of the follicle; rather, it supports the corpus luteum. Choice C is incorrect as the implantation site for the developing embryo is the endometrium of the uterus, not the placenta itself. Choice D is incorrect because the placenta does not stimulate the development of the corpus luteum; instead, it supports its function through hCG production.
What normally inhibits testosterone production?
- A. increasing FSH
- B. increasing ICSH
- C. decreasing ICSH
- D. decreasing FSH
Correct Answer: B
Rationale: The correct answer is B because increasing ICSH (Luteinizing Hormone) inhibits testosterone production by exerting negative feedback on the testes. ICSH stimulates Leydig cells in the testes to produce testosterone. When testosterone levels rise, it signals the pituitary gland to decrease ICSH secretion, thus inhibiting further testosterone production.
A: Increasing FSH (Follicle-Stimulating Hormone) does not inhibit testosterone production.
C: Decreasing ICSH would lead to reduced stimulation of Leydig cells and lower testosterone production.
D: Decreasing FSH would not directly inhibit testosterone production as FSH primarily stimulates sperm production in the testes.
While working on the surgical unit, you are assigned to care for a client who has just returned to the surgical unit after a TURP. You assess the client and obtain these data. Which finding will require the most immediate action?
- A. Client's blood pressure reading is 153/88.
- B. Client's catheter is draining bright red blood.
- C. Client is not wearing anti-embolism hose.
- D. Client is complaining of abdominal cramping.
Correct Answer: B
Rationale: Bright red blood in the catheter may indicate hemorrhage, requiring immediate attention.
