Of the two functional areas of the years of age is known as ________. It blastocyst, the three primary germ is during this time that the reproductive layers form from the ________. organs grow to their adult size and
- A. amnion become functional under the influence
- B. morula of hormones.
- C. inner cell mass
- D. adulthood
Correct Answer: D
Rationale: The correct answer is D: adulthood. The question is referring to the two functional areas of life - childhood and adulthood. During adulthood, organs grow to their adult size and mature, reproductive organs become functional under the influence of hormones.
A: amnion become functional under the influence - Incorrect. Amnion is a membrane surrounding the embryo, not related to the functional areas of age.
B: morula of hormones - Incorrect. Morula is an early stage of embryonic development, not related to the functional areas of age.
C: inner cell mass - Incorrect. Inner cell mass is a part of the blastocyst, not related to the functional areas of age.

About the vascularization of the uterus we can state the following:
- A. the arteries branch off the common iliac artery;
- B. the arteries are branches off the abdominal aorta;
- C. the veins open in the inferior vena cava;
- D. the arteries are branches off the internal iliac artery;
Correct Answer: B
Rationale: The correct answer is B because the arteries supplying the uterus arise from the abdominal aorta. The uterine arteries branch off the anterior division of the internal iliac artery, which itself arises from the posterior division of the internal iliac artery. This vascular supply ensures that the uterus receives oxygenated blood rich in nutrients necessary for its proper function.
Choice A is incorrect because the common iliac artery does not directly supply blood to the uterus. Choice C is incorrect because the veins draining the uterus ultimately empty into the internal iliac veins, which then drain into the common iliac veins and not directly into the inferior vena cava. Choice D is incorrect because while the uterine arteries are indeed branches off the internal iliac artery, the internal iliac artery itself arises from the common iliac artery and not directly from the abdominal aorta.
Where does fertilization normally take place?
- A. Uterus
- B. Cervix
- C. Ovary
- D. Ampulla of the fallopian tubes
Correct Answer: D
Rationale: The correct answer is D: Ampulla of the fallopian tubes. Fertilization typically occurs in the ampulla of the fallopian tubes, where the sperm meets the egg. The ampulla is the widest part of the fallopian tube, providing the necessary space for fertilization to occur. Sperm must travel through the cervix and uterus to reach the fallopian tubes where fertilization takes place. The ovary is where the egg is released during ovulation but fertilization occurs in the fallopian tubes.
When assessing a client with cervical cancer who had a total abdominal hysterectomy yesterday, you obtain the following data. Which information has the most immediate implications for planning the client's care?
- A. Fine crackles are audible at the lung bases.
- B. Client's right calf is swollen and tender.
- C. Client is using the PCA every 15 minutes.
- D. Urine in the collection bag is amber and clear.

A 49-yr-old man who has type 2 diabetes, high blood pressure, hyperlipidemia, and gastroesophageal reflux tells the nurse that he has had recent difficulty in achieving an erection. Which of the following drugs from his current medications list may cause erectile dysfunction (ED)?
- A. Ranitidine (Zantac)
- B. Atorvastatin (Lipitor)
- C. Propranolol (Inderal)
- D. Metformin (Glucophage)
Correct Answer: C
Rationale: The correct answer is C: Propranolol (Inderal). Propranolol is a beta-blocker commonly used to treat high blood pressure, which can lead to erectile dysfunction (ED) as a side effect by affecting blood flow. The other choices, A: Ranitidine (Zantac) is an H2 blocker used for GERD; B: Atorvastatin (Lipitor) is a statin used to lower cholesterol; and D: Metformin (Glucophage) is an oral antidiabetic agent. These medications are not typically associated with causing ED.
The scrotum:
- A. is located above the external male genital organ;
- B. shelters the male gonad;
- C. is made up of concentric tunics, a continuation of the ones from the anterior abdominal wall;
- D. is part of the external genital organs;
Correct Answer: B
Rationale: The correct answer is B: shelters the male gonad. The scrotum houses and protects the testes, the male gonads responsible for sperm production. This is crucial for maintaining optimal temperature for spermatogenesis. Choices A, C, and D are incorrect as the scrotum is located below the external male genital organ, has separate tunics from the abdominal wall, and is considered part of the external genital organs.
