The testicle secrets the following hormones:
- A. androgenic;
- B. progesterone;
- C. testosterone;
- D. progesterone
Correct Answer: C
Rationale: Step 1: The testicles are primarily responsible for producing male sex hormones.
Step 2: Testosterone is the main male sex hormone secreted by the testes.
Step 3: Testosterone is an androgenic hormone responsible for male characteristics.
Step 4: Progesterone is a female sex hormone, not primarily secreted by the testicles.
Step 5: Therefore, the correct answer is C (testosterone).

The child's sex is determined by:
- A. the type of the spermatozoon that fecundates the ovule;
- B. the type of the fecundated ovule;
- C. the sex chromosome of the ovule;
- D. the sex chromosome of the spermatozoon
Correct Answer: D
Rationale: The correct answer is D because the sex of the child is determined by the sex chromosome carried by the spermatozoon that fertilizes the ovule. Sperm carries either an X or a Y chromosome, determining if the child will be male (XY) or female (XX). Choices A and B are incorrect because the type of spermatozoon or ovule does not solely determine the child's sex. Choice C is incorrect as well because the sex chromosome of the ovule alone does not determine the child's sex.
The ovule forms in:
- A. the medullar area of the ovary;
- B. the mature ovarian follicle;
- C. the Fallopian tube;
- D. the uterus;
Correct Answer: B
Rationale: The correct answer is B: the mature ovarian follicle.
1. Ovule formation occurs within the ovary, specifically within a structure called the ovarian follicle.
2. The mature ovarian follicle contains the ovum (oocyte) which develops into the ovule.
3. The ovule is released during ovulation from the mature ovarian follicle.
In contrast, the other choices are incorrect:
A: The medullar area of the ovary does not play a direct role in ovule formation.
C: The Fallopian tube is where fertilization typically occurs, not ovule formation.
D: The uterus is not involved in ovule formation; it is the site of embryo implantation during pregnancy.
Vaginal candidacies are suspected in a young woman who complains of severe vaginal itching. Which of the following nursing actions should be performed first when assisting in the collection of a vaginal smear for microscopic examination?
- A. Inspect the external genitalia
- B. Don gloves
- C. Wash hands
- D. Label the specimen
Correct Answer: B
Rationale: Donning gloves is the first step to ensure hygiene and prevent contamination during specimen collection.
This is an inflammation of the fallopian tubes and the pelvic organs secondary to infections with gonococcus or chlamydia
- A. Ovarian cyst
- B. Endometriosi
- C. PID
- D. Cervicitis
Correct Answer: C
Rationale: Step 1: Pelvic inflammatory disease (PID) is an infection of the fallopian tubes and pelvic organs.
Step 2: PID is commonly caused by gonococcus or chlamydia infections.
Step 3: Ovarian cyst (A) is a fluid-filled sac on the ovary, not related to infections.
Step 4: Endometriosis (B) is the growth of endometrial tissue outside the uterus, not typically associated with infections.
Step 5: Cervicitis (D) is an inflammation of the cervix, not involving the fallopian tubes and pelvic organs.
What results from spermiogenesis? ________.
- A. four spermatogonia
- B. emission
- C. four spermatids
- D. menses
Correct Answer: C
Rationale: Spermiogenesis is the process of spermatid maturation into spermatozoa. During this process, each spermatid transforms into a single sperm cell. Therefore, the correct answer is C: four spermatids, as spermiogenesis results in the formation of four mature sperm cells from each spermatid.
A: Four spermatogonia are the cells that undergo mitosis to produce spermatocytes, not the result of spermiogenesis.
B: Emission refers to the release of semen during ejaculation, not the result of spermiogenesis.
D: Menses is the shedding of the uterine lining during the menstrual cycle in females, not related to spermiogenesis.
