Within which structure in the human body does specialization of parts of the developing baby take place?
- A. ovary
- B. uterus
- C. testis
- D. pancreas
Correct Answer: B
Rationale: The correct answer is B: uterus. Specialization of parts of the developing baby takes place in the uterus during pregnancy. The uterus is where the fertilized egg implants and the embryo develops into a specialized structure known as a fetus. The other choices (A: ovary, C: testis, D: pancreas) do not play a direct role in the development of the baby during pregnancy. The ovary is involved in producing eggs, the testis produces sperm, and the pancreas is responsible for producing digestive enzymes and hormones, but they are not directly involved in the specialization of parts of the developing baby.

During the 12-hr period preceding ovulation, which of the following is true?
- A. The plasma concentration of estrogen is rising
- B. A surge of luteinizing hormone is secreted from the pituitary
- C. The surge occurs immediately after the formation of the corpus luteum
- D. The surge followed immediately by a fall in the plasma concentration of progesterone
Correct Answer: B
Rationale: The correct answer is B because a surge of luteinizing hormone (LH) is necessary for ovulation to occur, typically happening 24-36 hours before ovulation. This surge triggers the release of the mature egg from the ovarian follicle. Choices A, C, and D are incorrect as estrogen levels peak just before ovulation, the corpus luteum forms after ovulation, and progesterone levels rise after ovulation, not fall immediately after the LH surge.
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.
Correct Answer: D
Rationale: Endometrial biopsies are typically minimally invasive and often do not require anesthesia.
Which structure lies posterior to the bladder and anterior to the rectum and secretes an alkaline, fructose filled fluid?
- A. Prostate
- B. bulbourethral gland
- C. Seminal vesicles
- D. Spongy urethra
Correct Answer: C
Rationale: The correct answer is C: Seminal vesicles. These glands are located posterior to the bladder and anterior to the rectum. They secrete an alkaline fluid rich in fructose, which nourishes and supports sperm viability. The other choices are incorrect because: A) The prostate is located below the bladder and surrounds the urethra, secreting a milky fluid; B) The bulbourethral gland is located below the prostate and secretes a clear, viscous fluid; D) The spongy urethra is a part of the male urethra that runs through the penis, responsible for transporting urine and semen.
PID is an infection of the pelvic organs, excepting the uterus. The nurse's role in caring for a client hospitalized with PID includes which of the following?
- A. The nurse inquires if the client has douched within the last 48 hours
- B. The nurse advises a douche every hour prior to being examined
- C. The nurse avoids administering analgesics
- D. The nurse avoids washing the perineal area
Correct Answer: A
Rationale: Inquiring about recent douching helps understand potential contributing factors to the infection.
The target of FSH is the _____.
- A. prostate
- B. seminiferous tubule
- C. pituitary
- D. penis
Correct Answer: B
Rationale: The correct answer is B: seminiferous tubule. FSH (follicle-stimulating hormone) targets the seminiferous tubules in the testes to stimulate the production of sperm. FSH plays a crucial role in male reproductive function by promoting spermatogenesis. The other choices are incorrect because:
A: Prostate - FSH does not directly target the prostate.
C: Pituitary - FSH is secreted by the pituitary gland, it does not target the pituitary itself.
D: Penis - FSH does not have a direct role in the structure or function of the penis.
