Before implantation, the blastocyst obtains its nutrition from the uterine endometrial secretions. How does the blastocyst obtain nutrition during the first week after implantation?

  • A. It continues to derive nutrition from endometrial secretions
  • B. The cells of the blastocyst contain stored nutrients that are metabolized for nutritional support
  • C. The placenta provides nutrition derived from maternal blood
  • D. The trophoblast cells digest the nutrient-rich endometrial cells and then absorb their contents for use by the blastocyst
Correct Answer: D

Rationale: Step 1: The trophoblast cells of the blastocyst invade the endometrial lining during implantation.
Step 2: The trophoblast cells secrete enzymes to digest the nutrient-rich endometrial cells.
Step 3: The digested nutrients are absorbed by the trophoblast cells.
Step 4: These nutrients are then utilized by the blastocyst for its growth and development.
Step 5: This process ensures that the blastocyst receives the necessary nutrition for the first week after implantation.
Summary:
A: Incorrect. Endometrial secretions are no longer the source of nutrition after implantation.
B: Incorrect. While the blastocyst may contain some stored nutrients, they are not sufficient for the first week post-implantation.
C: Incorrect. The placenta is not fully functional until later in pregnancy, so it does not provide nutrition in the first week.

A drug is given that affects the initial phases of spermatogenesis to aid in a patient’s infertility complaints. How much time would it take for the effects of this drug to be seen?

  • A. 4.6 days
  • B. 16 days
  • C. 22 days
  • D. 86 days
Correct Answer: D

Rationale: The correct answer is D (86 days) because spermatogenesis is a process that takes around 74 days from the initial division of spermatogonia to the release of mature spermatozoa. The drug affecting the initial phases of spermatogenesis would take at least one full cycle of spermatogenesis to show its effects, which is around 74 days. Therefore, it would take approximately 86 days for the effects of the drug to be seen.

Choice A (4.6 days) is too short for spermatogenesis to complete, so the effects of the drug would not be observable in this time frame. Choice B (16 days) and Choice C (22 days) are also insufficient for a full cycle of spermatogenesis to occur, hence the effects of the drug would not be evident within these durations.

The veins of the ovary can open into:

  • A. inferior vena cava;
  • B. uterine vein;
  • C. renal vein;
  • D. internal iliac vein;
Correct Answer: D

Rationale: The correct answer is D: internal iliac vein. The veins of the ovary drain into the ovarian veins, which then connect to the pampiniform plexus, ultimately draining into the internal iliac vein. This pathway allows for the blood from the ovary to be carried back to the heart. The other choices (A, B, C) are incorrect as the ovarian veins do not typically open into the inferior vena cava, uterine vein, or renal vein.

Which of the following is NOT a part of

  • A. labor a male's testis?
  • B. menarche
  • C. seminiferous tubule
  • D. menstruation
Correct Answer: B

Rationale: The correct answer is B: menarche. Menarche refers to the onset of a female's first menstrual period, not related to male reproductive anatomy. Choice A, labor a male's testis, involves the process of childbirth and is not related to male reproductive anatomy. Choice C, seminiferous tubule, is a part of the male reproductive system where sperm is produced. Choice D, menstruation, is the monthly shedding of the uterine lining in females, not related to male reproductive anatomy. Therefore, menarche is the only choice that does not pertain to male reproductive anatomy.

Estrogen replacement therapy is given to relieve the symptoms of:

  • A. Cervicitis
  • B. Pregnancy
  • C. Endometriosis
  • D. Menopause
Correct Answer: D

Rationale: Estrogen replacement therapy is given to relieve the symptoms of menopause because it helps alleviate hot flashes, night sweats, vaginal dryness, and other menopausal symptoms by replacing the declining estrogen levels in the body. Cervicitis is inflammation of the cervix and is not treated with estrogen therapy. Pregnancy naturally increases estrogen levels and does not require estrogen replacement therapy. Endometriosis is a condition where endometrial tissue grows outside the uterus and is not specifically treated with estrogen replacement therapy. In summary, estrogen replacement therapy is indicated for menopausal symptoms due to declining estrogen levels.

Mrs. Smith balks at the idea of looking at her incision. It would be most appropriate to

  • A. insist that she look at the incision
  • B. document her refusal in the chart
  • C. respect her feelings
  • D. arrange for a psychiatric consultation
Correct Answer: C

Rationale: Respecting her feelings acknowledges her emotional state and promotes trust.
