Nokea
The epididymis:
- A. is comm
- B. shaped;
- C. is crossed by the deferent duct (vas deferens);
- D. displays tunica albuginea on the inside;
Correct Answer: C
Rationale: Step 1: The epididymis is a structure where sperm mature and are stored.
Step 2: The deferent duct (vas deferens) carries sperm from the epididymis to the urethra.
Step 3: Since the deferent duct crosses the epididymis, choice C is correct.
Summary: Choices A, B, and D are incorrect because they do not accurately describe the anatomical relationship between the epididymis and the deferent duct.

Which of the following is a steroid?
- A. FSH
- B. LH
- C. estrogen
- D. GnRH
Correct Answer: C
Rationale: The correct answer is C: estrogen. Estrogen is a type of steroid hormone derived from cholesterol. Steroids are a specific group of lipids characterized by a particular molecular structure. Estrogen plays a vital role in the development and regulation of the female reproductive system.
Choice A, FSH, and choice B, LH, are both peptide hormones, not steroids. Peptide hormones are made up of amino acids and are not derived from cholesterol.
Choice D, GnRH, is also a peptide hormone that regulates the release of other hormones in the body, particularly in the reproductive system.
In summary, estrogen is the only steroid hormone among the options provided, making it the correct choice.
The cortical area of the ovary contains:
- A. primordial follicles;
- B. mature follicles;
- C. secondary follicles;
- D. blood vessels;
Correct Answer: A
Rationale: Step 1: The cortical area of the ovary is the outer layer where follicles develop.
Step 2: Primordial follicles are the earliest stage of follicle development, found in the cortex.
Step 3: Mature follicles are developed follicles located deeper in the ovary, not in the cortex.
Step 4: Secondary follicles are also more developed than primordial follicles, located deeper.
Step 5: Blood vessels are important for supplying nutrients but are not specific to the cortical area.
Therefore, the correct answer is A as primordial follicles are located in the cortical area, while other choices are found in different regions of the ovary.
Which statement by Mrs. Carson would indicate to you that she does NOT have a complete understanding of the self breast examination technique?
- A. I do the examination every month a few days after my period.'
- B. I use my fingertips to examine all of the breast tissues.'
- C. I begin the examination by inspecting my breasts with hands at my side.'
- D. I especially check the upper, outer quadrant and under my arms.'
Correct Answer: C
Rationale: Beginning the examination by inspecting the breasts with hands at the side is not the correct technique; hands should be raised above the head.
Each spermatid and each ovum have ________. ________.
- A. glans penis
- B. 23 pairs of chromosomes
- C. shaft of the penis
- D. 23 chromosomes
Correct Answer: D
Rationale: The correct answer is D: 23 chromosomes. Spermatids and ova are haploid cells formed through meiosis, containing only half the number of chromosomes (23) as a normal diploid cell. This is essential for maintaining the proper chromosome number when fertilization occurs. Glans penis and shaft of the penis (choices A and C) are structures related to the male reproductive system but are not present in spermatids or ova. Having 23 pairs of chromosomes (choice B) would result in a total of 46 chromosomes, which is incorrect for these gametes.
The nurse is developing a teaching plan for a client who is scheduled for her first Papanicolaou test. What instruction by the nurse is the most accurate?
- A. “The timing of the Pap smear does not matter.”
- B. “Sexual intercourse will not interfere with the results.”
- C. “Results can be interpreted immediately in the offic
- D. “Results are best if you do not douche 24 hours before the test.”
Correct Answer: D
Rationale: The correct answer is D. Douching can alter the cervical cells and affect the accuracy of the Pap smear results. The rationale is that douching can wash away or change the cervical cells, leading to potential misinterpretation of the test results. Choices A and B are incorrect because the timing of the test and sexual activity can indeed affect the results. Choice C is incorrect as Pap smear results need to be sent to a lab for interpretation by a healthcare provider, not done immediately in the office.
