Seven days after ovulation, pituitary secretion of luteinizing hormone (LH) decreases rapidly. What is the cause of this decrease in secretion?
- A. The anterior pituitary gland becomes unresponsive to the stimulatory effect of gonadotropin-releasing hormone (GnRH)
- B. Estrogen from the developing follicles exerts a feedback inhibition on the hypothalamus
- C. The rise in body temperature inhibits hypothalamic release of GnRH
- D. Secretion of estrogen and progesterone by the corpus luteum suppresses hypothalamic secretion of GnRH and pituitary secretion of LH
Correct Answer: D
Rationale: Step 1: After ovulation, the follicle transforms into the corpus luteum.
Step 2: The corpus luteum secretes estrogen and progesterone.
Step 3: Estrogen and progesterone exert negative feedback on the hypothalamus.
Step 4: This inhibits the secretion of GnRH from the hypothalamus.
Step 5: Decreased GnRH leads to reduced LH secretion from the pituitary.
Therefore, the correct answer is D because the secretion of estrogen and progesterone by the corpus luteum suppresses the hypothalamic secretion of GnRH, resulting in decreased pituitary LH secretion.
Summary:
A: Incorrect. The anterior pituitary gland's responsiveness to GnRH is not the cause of the decrease in LH secretion.
B: Incorrect. Estrogen exerts negative feedback on the hypothalamus, not the pituitary.
C: Incorrect. Rise in body temperature does not directly inhibit GnRH secretion
The day after having a radical prostatectomy, your client has many blood clots in the urinary catheter and states he has frequent bladder spasms. You notice occasional urine leakage around the catheter at the urinary meatus. The client says that his right calf is sore and complains that he feels short of breath. Which action will you take first?
- A. Irrigate the catheter with 50 mL of sterile saline.
- B. Administer oxybutynin (Ditropan) 5 mg orally.
- C. Dorsiflex the foot to check for Homans' sign.
- D. Obtain an oxygen saturation using pulse oximetry.
Correct Answer: D
Rationale: Shortness of breath and calf soreness suggest a pulmonary embolism; obtaining oxygen saturation is critical.
The __________________ is a thick, muscular organ that can expand to accommodate a developing baby.
- A. Uterus
- B. Ovary
- C. Vulva
- D. Breast
Correct Answer: A
Rationale: The correct answer is A: Uterus. The uterus is a thick, muscular organ located in the lower abdomen where a developing baby grows during pregnancy. It can expand significantly to accommodate the growth of the fetus. The ovaries (B) are responsible for producing eggs, not for accommodating a developing baby. The vulva (C) refers to the external female genitalia, not the organ that supports pregnancy. The breast (D) is responsible for producing milk after childbirth, not for housing a developing baby.
This tiny gland produces a secretion that is similar to a large lysosome and that cleanses the male urethra of assists penetration of the egg is called traces of acidic urine prior to the ________.
- A. flagellum
- B. prostate
- C. midpiece
- D. bulbo-urethral gland
Correct Answer: D
Rationale: The correct answer is D: bulbo-urethral gland. This gland produces a clear secretion that neutralizes traces of acidic urine, lubricates the urethra, and assists in sperm motility. The other choices are incorrect because:
A: Flagellum is a structure on sperm cells for propulsion.
B: Prostate produces seminal fluid but does not cleanse the urethra.
C: Midpiece is a part of the sperm cell that contains mitochondria for energy production, not a gland.
The ovary:
- A. is a gland with mixed role;
- B. has exocrine role, secreting the female sexual hormones;
- C. has endocrine role, generating the ovules;
- D. represents the female gonad;
Correct Answer: D
Rationale: The correct answer is D because the ovary is indeed the female gonad responsible for producing eggs and releasing female sex hormones like estrogen and progesterone. This is its primary function, making it the most accurate choice. Choice A is incorrect as the ovary's main role is reproductive rather than mixed. Choice B is incorrect as the ovary secretes both female sex hormones and eggs, not just hormones. Choice C is incorrect as ovules are part of the female reproductive system but not the main function of the ovary.
