Nokea
Which cells secrete testosterone?
- A. Sertoli cells
- B. Spermatogenic cells
- C. Leydig cells
- D. Oogonia
Correct Answer: C
Rationale: Step-by-step rationale:
1. Leydig cells are located in the testes and are responsible for secreting testosterone.
2. Testosterone is a male sex hormone crucial for regulating various functions in the body.
3. Sertoli cells provide support for sperm development, not testosterone secretion.
4. Spermatogenic cells are involved in sperm production, not testosterone secretion.
5. Oogonia are female germ cells, not involved in testosterone secretion.
Summary:
Choice C (Leydig cells) is correct because they are the specific cells in the testes responsible for secreting testosterone. Choices A, B, and D are incorrect as they are associated with other functions related to reproduction and are not involved in testosterone secretion.

During the initial inspection of the female genitalia, the nurse recognizes which finding as normal?
- A. The labia minora are hair-covered and lying within the labia majora.
- B. The cervical os in the multiparous woman has the shape of a small circle.
- C. The vaginal vestibule lies between the labia minora and contains the urinary meatus.
- D. The openings of Skene and Bartholin glands are visible posteriorly.
Correct Answer: C
Rationale: The correct answer is C because the vaginal vestibule lies between the labia minora and contains the urinary meatus, which is a normal anatomical finding. The labia minora being hair-covered and lying within the labia majora (A) is not normal. The cervical os in a multiparous woman should have a shape of a transverse slit, not a small circle (B). The openings of Skene and Bartholin glands are not typically visible during the initial inspection of the female genitalia (D).
Which of the following reasons would make a client who was treated successfully for a chlamydia infection at a greater risk for acquiring AIDS?
- A. The tissue irritation may be permanent, despite successful eradication of the bacteria.
- B. The immune system is already compromised.
- C. The bacterium Chlamydia trachomatis causes AIDS.
- D. The bacterium Chlamydia trachomatis continues to live inside the cells it has infected.
Correct Answer: B
Rationale: Having had an STI indicates existing vulnerabilities in the immune system, increasing susceptibility to HIV/AIDS.
Which hormone causes the uterus to increase glycogen?
- A. progesterone
- B. FSH
- C. LH
- D. estrogen
Correct Answer: A
Rationale: Progesterone is the correct answer because it is responsible for preparing the uterus for potential implantation by increasing glycogen levels. Progesterone promotes the growth of blood vessels and glands in the uterus, leading to increased glycogen production. FSH and LH are involved in the menstrual cycle and ovulation but do not directly impact glycogen levels in the uterus. Estrogen plays a role in the growth and thickening of the endometrial lining but does not specifically stimulate glycogen production.
The primary germ layer that gives rise
- A. areolar glands to the mucosae and associated glands
- B. lacrimal glands is the ________.
- C. sweat glands
- D. ectoderm
Correct Answer: D
Rationale: The correct answer is D: ectoderm. The primary germ layer that gives rise to structures like the lacrimal glands is the ectoderm, which is one of the three primary germ layers during embryonic development. The ectoderm gives rise to tissues such as the epidermis of the skin, nervous system, and various glands including lacrimal glands. Choice A, areolar glands to the mucosae and associated glands, is incorrect as they are derived from the mesoderm. Choice C, sweat glands, is also incorrect as they are derived from the ectoderm but are not the primary germ layer responsible for lacrimal glands. Choice B, lacrimal glands is the _______, is incorrect as it does not provide a complete statement and is not a primary germ layer.
Which of the following instructions would a nurse give a client undergoing treatment for an HSV-2 infection?
- A. Have an annual Papanicolaou smear to detect cervical cancer.
- B. Have an annual mammogram to detect breast cancer.
- C. Increase the frequency of breast self-examination for early detection of any breast disorders.
- D. Undergo an HIV detection test every six months.
Correct Answer: A
Rationale: Regular Pap smears are important for detecting cervical changes related to HSV-2.
