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.

- B. Elevate the client's arm on two pillows to promote lymphatic drainage.

The uterus displays the following components:
- A. the cervix;
- B. the corpus;
- C. the head;
- D. the mid piece;
Correct Answer: A
Rationale: The correct answer is A: the cervix. The cervix is a component of the uterus that connects the uterus to the vagina. It plays a crucial role in pregnancy, as it dilates during childbirth to allow the baby to pass through. The other choices, B: the corpus, C: the head, and D: the mid piece, are incorrect as they do not refer to components of the uterus. The corpus typically refers to the main body of an organ, while the head and mid piece are terms commonly associated with structures in cells or organisms, not the uterus.
The fructose in semen is secreted by
- A. the epididymis.
- B. the seminiferous tubules.
- C. the seminal vesicles.
- D. the prostate glands.
Correct Answer: C
Rationale: The correct answer is C, the seminal vesicles. Seminal vesicles secrete fructose in semen to provide energy for sperm motility. This process occurs after sperm leave the epididymis and seminiferous tubules, ruling out choices A and B. The prostate glands contribute to the alkaline fluid in semen, not fructose, eliminating choice D. Therefore, choice C is correct due to its role in providing energy for sperm function.
A client is having a hysterosalpingogram. What action by the nurse is most important?
- A. Assist the client in sitting up after the procedure
- B. Provide the client with a pad to avoid dye stains on the clothes.
- C. Teach her to take all antibiotics prescribed until finished
- D. Inform the client that the procedure may cause shoulder pain.
Correct Answer: A
Rationale: The correct answer is A: Assist the client in sitting up after the procedure. This is important to prevent complications like vasovagal response or fainting due to sudden positional changes. Sitting up slowly helps stabilize blood pressure and prevent dizziness.
B: Providing a pad for dye stains is not the most important action as it is a minor concern compared to client safety post-procedure.
C: Taking antibiotics has no direct relevance to the hysterosalpingogram procedure, so it is not the most important action.
D: Informing the client about potential shoulder pain is helpful, but ensuring immediate safety by assisting the client in sitting up takes precedence.
