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.

A nurse identifies a client with an abnormal lab test that screens for prostate cancer. What is the test that the client will receive to screen for prostate cancer?
- A. PAS
- B. APS
- C. PSA
- D. PCA
Correct Answer: C
Rationale: PSA (Prostate-Specific Antigen) is the standard screening test for prostate cancer.
A 67-year-old male client had some serum tests performed during his annual examination. The nurse reviews his results, as follows: testosterone: 680 ng/dL; prostate-specific antigen: 10 ng/mL; prolactin: 5 ng/mL. What action by the nurse is best?
- A. Assess for possible galactorrhea with breast discharge.
- B. Note the possibility of a testicular tumor.
- C. Communicate to the provider that results were normal
- D. Prepare the client for further diagnostic testing
Correct Answer: D
Rationale: The correct answer is D: Prepare the client for further diagnostic testing. A testosterone level of 680 ng/dL is high for a 67-year-old male, which could indicate an underlying medical condition. A prostate-specific antigen level of 10 ng/mL is elevated and could suggest prostate issues. Prolactin level of 5 ng/mL is within normal range but still needs further evaluation due to the other abnormal results. Therefore, preparing the client for further diagnostic testing is crucial to investigate the potential underlying health concerns.
Incorrect options:
A: Assess for possible galactorrhea with breast discharge - Irrelevant as galactorrhea is not indicated by the given results.
B: Note the possibility of a testicular tumor - Testosterone level elevation is more indicative of non-testicular issues.
C: Communicate to the provider that results were normal - Results are not normal, warranting further evaluation.
Within which structure in the human body does specialization of parts of the developing baby take place?
- A. ovary
- B. uterus
- C. testis
- D. pancreas
Correct Answer: B
Rationale: The correct answer is B: uterus. Specialization of parts of the developing baby takes place in the uterus during pregnancy. The uterus is where the fertilized egg implants and the embryo develops into a specialized structure known as a fetus. The other choices (A: ovary, C: testis, D: pancreas) do not play a direct role in the development of the baby during pregnancy. The ovary is involved in producing eggs, the testis produces sperm, and the pancreas is responsible for producing digestive enzymes and hormones, but they are not directly involved in the specialization of parts of the developing baby.
PID is:
- A. Prostate inflammatory disease
- B. Pelvic infiltrative disorder
- C. Pelvic inflammatory disease
- D. Prostate inhibitory disorder
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct:
1. PID stands for Pelvic Inflammatory Disease.
2. PID is an infection of the female reproductive organs, including the uterus, fallopian tubes, and ovaries.
3. Symptoms include pelvic pain, abnormal vaginal discharge, fever, and painful urination.
4. Choice A is incorrect because PID does not specifically refer to the prostate.
5. Choice B is incorrect as PID does not involve infiltration but rather inflammation.
6. Choice D is incorrect as PID is not a disorder that inhibits the prostate.
Fertilization usually occurs in the nuclear division only. ______.
- A. Meiosis produces two
- B. ovary
- C. vesicular (Graafian) follicle
- D. Meiosis occurs in all cells of
Correct Answer: D
Rationale: The correct answer is D because meiosis occurs in all cells of the body. Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes. Fertilization, the fusion of sperm and egg, typically occurs after meiosis in the reproductive organs. Choices A, B, and C are incorrect because they do not directly relate to the process of fertilization or meiosis occurring in all cells. Choice A talks about the outcome of meiosis, choice B refers to a specific organ, and choice C mentions a stage in the development of an egg cell.
