Which structure will actually become the fetus?
- A. morula
- B. blastocyst
- C. inner cell mass
- D. zygote
Correct Answer: C
Rationale: The correct answer is C: inner cell mass. After fertilization, the zygote undergoes several cell divisions to form a hollow ball of cells called a blastocyst. Within the blastocyst, the inner cell mass contains cells that will develop into the fetus. The morula is an earlier stage consisting of a solid ball of cells. The zygote is the initial cell formed from the fusion of egg and sperm, but it does not directly become the fetus. Therefore, the inner cell mass is the structure that will actually develop into the fetus, making it the correct answer.

The evolutionary stages of the ovarian follicles are:
- A. secondary;
- B. tertiary (de Graaf);
- C. primordial;
- D. evolutionary;
Correct Answer: C
Rationale: The correct answer is C: primordial. Ovarian follicles go through several stages of development. Primordial follicles are the earliest stage, containing primary oocytes surrounded by a single layer of squamous cells. This stage represents the resting pool of follicles. Secondary follicles come next, with primary oocytes surrounded by multiple layers of granulosa cells. Tertiary (de Graaf) follicles are the most advanced stage, containing a fluid-filled antrum and a mature oocyte. Evolutionary is not a recognized stage in ovarian follicle development. Secondary is incorrect as it comes after primordial, and tertiary is incorrect as it is not the earliest stage.
Arterial supply of breast include
- A. Internal thoracic artery
- B. Thoracoaromial artery
- C. Superior epigastric artery
- D. Common carotid artery
Correct Answer: A
Rationale: The correct answer is A: Internal thoracic artery. The internal thoracic artery is a major branch of the subclavian artery and supplies the breast tissue. It gives rise to the perforating branches that supply the breast. The other choices, B, C, and D, are incorrect because the thoracoaromial artery primarily supplies the upper limb, the superior epigastric artery supplies the anterior abdominal wall, and the common carotid artery supplies the head and neck, but not the breast tissue. Therefore, based on the anatomical knowledge of arterial supply, the internal thoracic artery is the correct choice for the arterial supply of the breast.
In what specific part of the male reproductive system do maturing sperm gain increased motility and their ability to swim?
- A. Seminiferous tubules
- B. Epididymis
- C. Ductus deferens
- D. Ejaculatory duct
Correct Answer: B
Rationale: The correct answer is B: Epididymis. The epididymis is where maturing sperm gain increased motility and their ability to swim due to the presence of specific proteins and enzymes that facilitate this process. Sperm leave the seminiferous tubules in an immature state and undergo maturation in the epididymis through interactions with these proteins. The ductus deferens and ejaculatory duct are not involved in the maturation process of sperm and do not contribute to their motility. The seminiferous tubules are responsible for sperm production but not for the maturation of sperm motility.
PID is an infection of the pelvic organs, excepting the uterus. The nurse's role in caring for a client hospitalized with PID includes which of the following?
- A. The nurse inquires if the client has douched within the last 48 hours
- B. The nurse advises a douche every hour prior to being examined
- C. The nurse avoids administering analgesics
- D. The nurse avoids washing the perineal area
Correct Answer: A
Rationale: Inquiring about recent douching helps understand potential contributing factors to the infection.
