We can state the following about the uterus:
- A. it is made up of corpus and cervix;
- B. the vagina is inserted on the cervix;
- C. the uterine cavity displays a mucous membrane that undergoes cyclical modifications;
- D. it has striated musculature, with longitudinal, radial and circular fibers;
Correct Answer: C
Rationale: Step 1: The uterine cavity displays a mucous membrane that undergoes cyclical modifications due to hormonal changes during the menstrual cycle.
Step 2: This mucous membrane is essential for embryo implantation and plays a crucial role in pregnancy.
Step 3: The cyclical modifications of the mucous membrane are necessary for the shedding of the endometrium during menstruation.
Summary: Choice C is correct because it accurately describes a key function of the uterus related to the menstrual cycle. Choices A, B, and D are incorrect as they do not address the specific function of the uterine cavity and its mucous membrane modifications.

Which of the following is suitable for the fertilization of an egg?
- A. Sperm
- B. Spermatid
- C. Primary spermatocyte
- D. Spermatogonium
Correct Answer: A
Rationale: The correct answer is A: Sperm. Sperm is the mature male reproductive cell capable of fertilizing an egg. It carries genetic material and is designed for the process of fertilization. Spermatid (B) is an immature sperm cell not yet capable of fertilizing an egg. Primary spermatocyte (C) is a cell undergoing meiosis to produce spermatids. Spermatogonium (D) is a stem cell that gives rise to spermatocytes but is not directly involved in fertilization. Therefore, only sperm (A) is suitable for fertilizing an egg.
If a woman has a tumor secreting large amounts of estrogen from the adrenal gland, which of the following will occur?
- A. Progesterone levels in the blood will be very low
- B. Her luteinizing hormone secretion rate will be totally suppressed
- C. She will not have normal menstrual cycles
- D. Her bones will be normally calcified
Correct Answer: B
Rationale: Correct Answer: B - Her luteinizing hormone secretion rate will be totally suppressed
Rationale:
1. The tumor secretes large amounts of estrogen, which can lead to negative feedback on the hypothalamus and pituitary gland.
2. Luteinizing hormone (LH) is crucial for ovulation and normal menstrual cycles.
3. High estrogen levels can suppress LH secretion, disrupting ovulation and menstrual cycles.
Summary of other choices:
A: Progesterone levels may actually be elevated due to the tumor-induced high estrogen levels.
C: The disruption of LH secretion can lead to abnormal menstrual cycles.
D: High estrogen levels can lead to bone loss due to inhibition of bone formation and increased bone resorption.
What is the source and function of HCG?
- A. uterus; cause labor
- B. ovary; stimulates FSH
- C. placenta; inhibits LH
- D. placenta; mimics LH
Correct Answer: D
Rationale: The correct answer is D: placenta; mimics LH.
Rationale:
1. HCG (Human Chorionic Gonadotropin) is produced by the placenta during pregnancy.
2. HCG mimics the action of LH (Luteinizing Hormone) to support the corpus luteum in producing progesterone.
3. This helps maintain the uterine lining and supports the pregnancy.
Summary:
A: Incorrect - Uterus does not produce HCG, and it does not cause labor.
B: Incorrect - Ovary does not produce HCG, and it does not stimulate FSH.
C: Incorrect - Placenta produces HCG, but it does not inhibit LH; instead, it mimics LH's actions.
Choose the CORRECT match. Animals Fertilization Embryonic development
- A. Dog Internal Oviparity
- B. Duck External Viviparity
- C. Frog External Oviparity
- D. Cat Internal Ovoviviparity
Correct Answer: C
Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because:
A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs.
B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally.
D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
You obtain all of these assessment data about your client with continuous bladder irrigation (CBI) after a transurethral resection of the prostate (TURP). Which information indicates the most immediate need for nursing intervention?
- A. The client states he feels a continuous urge to void.
- B. The catheter drainage is light pink with occasional clots.
- C. The catheter is pulled taut and taped to the client's thigh.
- D. The client complains of painful bladder spasms.
Correct Answer: D
Rationale: Painful bladder spasms can indicate complications such as clot formation or obstruction, requiring immediate attention.
