Parturition occurs the fetus is the ________. approximately how many days after a
- A. amnion woman's last menstrual cycle ______.
- B. placenta
- C. 180 days
- D. chorionic villi
Correct Answer: D
Rationale: The correct answer is D: chorionic villi. Parturition occurs when the fetus releases cortisol, which stimulates the production of prostaglandins leading to uterine contractions. Chorionic villi are the fetal tissue that produces cortisol, making it the key factor triggering labor.
A: Amnion is the innermost membrane around the fetus, not directly involved in labor initiation.
B: Placenta plays a role in nutrient exchange but not in triggering labor.
C: 180 days is a set time frame and does not relate to the process of parturition.

What procedure does a nurse use to assess the inguinal ring of a male patient for a hernia?
- A. Asks the patient to lie supine, lifts the scrotum, asks the patient to take a deep breath, and observes for a bulge
- B. Asks the patient to lean over the examination table, inserts a gloved finger into the lower part of the scrotum into the inguinal canal, asks the patient to cough, and palpates for a bulge
- C. Asks the patient to lie on the side not being assessed, inserts a gloved finger into the lower part of the scrotum into the inguinal canal, asks the patient to exhale completely, and palpates for a bulge
- D. Asks the patient to stand, inserts a gloved finger into the lower part of the scrotum into the inguinal canal, asks the patient to cough, and palpates for a bulge
Correct Answer: D
Rationale: The correct answer is D because the nurse should assess the inguinal ring with the patient standing. This position allows gravity to aid in the detection of a hernia. By asking the patient to cough, intra-abdominal pressure increases, making any bulge more noticeable. Palpating for a bulge while the patient coughs helps to confirm the presence of a hernia.
Choice A is incorrect because assessing the inguinal ring with the patient lying supine does not utilize gravity to assist in detecting a hernia.
Choice B is incorrect because inserting a gloved finger into the lower part of the scrotum is not a proper technique for assessing the inguinal ring for a hernia in a male patient.
Choice C is incorrect because asking the patient to lie on the side not being assessed does not provide the optimal position for assessing the inguinal ring for a hernia.
The spongy tissue of the penis fills
- A. circumcision with blood during sexual excitement
- B. spermatogenesis and causes the penis to enlarge and
- C. ejaculation become rigid during ________.
- D. erection
Correct Answer: D
Rationale: The spongy tissue of the penis fills with blood during an erection to cause the penis to become rigid. This process is essential for maintaining an erection during sexual activity. Spermatogenesis refers to the production of sperm, not the filling of spongy tissue. Circumcision does not involve the filling of spongy tissue with blood. Ejaculation is the release of semen and does not involve the filling of spongy tissue. Therefore, the correct answer is D as it accurately describes the physiological process of penile erection.
Which hormone is necessary for the growth of endometrial glands, which are important for the sustenance of a growing embryo until its implantation?
- A. Luteinizing hormone (LH)
- B. Testosterone
- C. Progesterone
- D. Inhibin
Correct Answer: C
Rationale: The correct answer is C: Progesterone. Progesterone is necessary for the growth of endometrial glands as it prepares the endometrium for implantation of the embryo. LH is responsible for ovulation, not endometrial gland growth. Testosterone is a male sex hormone and not directly involved in endometrial gland growth. Inhibin regulates FSH secretion, not endometrial gland growth.
