About the external male genital organ, we can state the following:
- A. it is part of the urinary ducts, being a urination organ;
- B. it is represented by the urethra;
- C. it is a pair organ;
- D. it is located above the scrotum, anterior to the pubian symphisis;
Correct Answer: B
Rationale: Step-by-step rationale for why answer B is correct:
1. The external male genital organ is represented by the urethra, which is the duct that carries urine from the bladder out of the body.
2. The urethra is responsible for both urination and ejaculation.
3. The other choices are incorrect because the external male genital organ is not part of the urinary ducts, not a pair organ, and not located above the scrotum.

Which one of the following is not a component of semen?
- A. Sperm
- B. Seminal fluid
- C. Prostatic fluid
- D. Bulbourethral fluid
Correct Answer: D
Rationale: The correct answer is D: Bulbourethral fluid. Semen is composed of sperm, seminal fluid, and prostatic fluid. Bulbourethral fluid is not a component of semen but contributes to pre-ejaculatory fluid. This fluid is released from the Cowper's glands and serves to lubricate the urethra prior to ejaculation. The other choices (A, B, C) are all essential components of semen that play crucial roles in sperm transport, nourishment, and protection.
The nurse monitors a client who has gone through an endoscopic examination. Following a culdoscopy, what does a nurse need to observe for in this client?

- C. The nurse observes the client for changes in skin color and for any rise in body temperature.

Which blood vessel in the fetus has the highest Po2?
- A. Ductus arteriosus
- B. Ductus venosus
- C. Ascending aorta
- D. Left atrium
Correct Answer: B
Rationale: The correct answer is B: Ductus venosus. The ductus venosus carries oxygenated blood from the umbilical vein to the inferior vena cava, bypassing the liver. This blood has the highest Po2 among the choices because it is coming directly from the placenta, where oxygen exchange occurs. The other choices (A, C, D) carry deoxygenated blood or blood with lower oxygen content in the fetal circulation. The ductus arteriosus shunts blood from the pulmonary artery to the aorta, so it carries deoxygenated blood. The ascending aorta and left atrium receive mixed oxygenated and deoxygenated blood, not the highest Po2.
Which diagnostic study is recommended for high-risk clients in addition to mammography?

Which of the followings is the inferior portion of the uterus. It consists of two parts (supravaginal, vaginal), two openings (internal os, external os) and a cervical canal.
- A. clitoris
- B. Ovary
- C. Cervix
- D. implatation
Correct Answer: C
Rationale: The correct answer is C: Cervix. The cervix is the inferior portion of the uterus that consists of two parts (supravaginal, vaginal), two openings (internal os, external os), and a cervical canal. The clitoris (A) is a small sensitive organ located at the top of the vulva. The ovary (B) is a female reproductive organ that produces eggs and hormones. Implantation (D) refers to the attachment of a fertilized egg to the uterine lining, not a specific anatomical structure within the uterus. The cervix clearly fits the description provided, making it the correct answer.
