Failure of the testes to descend into mitotic cell divisions occur as the the scrotum is a condition known as zygote travels down the uterine ________.
- A. phimosis
- B. the acrosomal reaction
- C. cryptorchidism
- D. cleavage
Correct Answer: C
Rationale: The correct answer is C: cryptorchidism. Cryptorchidism is the condition where one or both testes fail to descend into the scrotum. This leads to impaired spermatogenesis as the temperature in the abdominal cavity is too high for proper sperm production. Phimosis (A) is the narrowing of the opening of the foreskin, unrelated to testicular descent. The acrosomal reaction (B) is a process during fertilization, not related to testicular descent. Cleavage (D) refers to the rapid mitotic cell divisions of the zygote, not associated with testicular descent.

What effect does luteinizing hormone uterine (fallopian) tubes is called the (LH) have on a female?
- A. LH promotes enlargement of
- B. body the female's breasts.
- C. fundus
- D. LH has no effect on a femal
Correct Answer: D
Rationale: Rationale:
1. LH is a hormone released by the pituitary gland.
2. Its main role in females is to trigger ovulation.
3. LH does not directly affect the uterine tubes or breast enlargement.
4. Therefore, the correct answer is D: "LH has no effect on a female."
Summary:
A, B, and C are incorrect because LH does not promote breast enlargement or affect the uterine tubes. The correct answer, D, is supported by the physiological functions of LH in the female reproductive system.
The superior portion of the uterus is the _____.
- A. body
- B. cervix
- C. fundus
- D. infundibulum
Correct Answer: C
Rationale: The correct answer is C: fundus. The fundus is the superior portion of the uterus, located above the entry point of the fallopian tubes. It is the part of the uterus where the fertilized egg implants and grows during pregnancy. The body of the uterus (choice A) is the main central portion, the cervix (choice B) is the lower narrow part that connects to the vagina, and the infundibulum (choice D) is a part of the fallopian tube, not the uterus. Thus, the fundus is the correct choice as it specifically refers to the superior portion of the uterus.
A male client is having trouble with erections and comes to the clinic to be seen by the doctor. The doctor diagnoses the client with erectile dysfunction. The nurse provides education regarding the disorder and teaches the client that erectile dysfunction can be caused by which of the following?
- A. Obsessive compulsive disorder
- B. Complications of STIs
- C. Side effects of drug therapy
- D. Spinal stenosis
Correct Answer: C
Rationale: Drug side effects are a common cause of erectile dysfunction.
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.
Foetal portion of placenta includes
- A. Decidua parietalis
- B. Chorion frondosum
- C. Decidua basalis
- D. Anchoring villi
Correct Answer: B
Rationale: The correct answer is B: Chorion frondosum. The foetal portion of the placenta is formed by the chorion frondosum, which consists of the chorionic villi that develop from the trophoblast. These villi are involved in the exchange of nutrients and waste products between the mother and the foetus.
A: Decidua parietalis is the maternal portion of the placenta, not the foetal portion.
C: Decidua basalis is also part of the maternal portion, not the foetal portion.
D: Anchoring villi are structures that help anchor the placenta to the uterine wall, but they are not specific to the foetal portion.
In summary, the correct answer is B because the chorion frondosum is specifically responsible for the foetal part of the placenta, while the other choices refer to maternal components or structures not directly related to the foetal portion.
