The female reproductive system includes the following structures:
- A. ovary;
- B. Fallopian tubes;
- C. vagina;
- D. vulva;
Correct Answer: A
Rationale: The correct answer is A: ovary. The female reproductive system includes the ovaries, which are responsible for producing eggs and hormones like estrogen and progesterone. The Fallopian tubes are passageways for eggs to travel from the ovaries to the uterus, not a part of the system itself. The vagina is the birth canal and where sperm enters during intercourse, but it is not a reproductive organ. The vulva includes external genitalia like the labia and clitoris, but it is not a reproductive structure. Therefore, the ovary is the only structure directly involved in the reproductive process.

Which of the following components of the fetoplacental (endocrine) unit is similar to thyroid stimulating hormone (TSH) and stimulates T4 secretion by the maternal thyroid?
- A. Human chorionic gonadotropin (hCG)
- B. Human chorionic somatomammotropin (hCS, hPL)
- C. IGF I and IGF II
- D. Endothelial growth factor (EGF)
Correct Answer: A
Rationale: Rationale:
1. Human chorionic gonadotropin (hCG) acts like TSH, stimulating T4 secretion by the maternal thyroid.
2. hCG is produced by the placenta and has a similar structure and function to TSH.
3. hCG binds to the TSH receptor on the thyroid gland, triggering T4 release.
4. Other options do not specifically target the thyroid gland for T4 secretion.
Summary:
A: hCG mimics TSH and directly stimulates T4 release.
B: hCS, hPL - involved in placental growth and lactation, not thyroid stimulation.
C: IGF I and II - growth factors, not directly related to thyroid function.
D: EGF - promotes cell growth and differentiation, not linked to thyroid hormone secretion.
A 22 year old male presents in your clinic, c/o pain in his testicle and penis. The pain began last night and has steadily become worse. He hurts when he urinates. He has not attempted intercourse since the pain began. He has tried Tylenol and Ibuprofen without improvement. Denies fever or night sweats. He has had 4 previous sexual partners and has had a new partner for the last month. She is using oral contraceptives and they do not use a condom. On exam, you see a young man lying on his side, mildly ill. His temp is 100.2. There are no visible lesions on the penis, or discharge from the meatus. The scrotum appears normal. Palpation of the testes reveals severe tenderness at the superior pole of the normal-sized left testicle. He also has tenderness when you palpate the structures superior to the testicle through the scrotal wall. The right testicle is unremarkable. An examining finger is placed through each inguinal ring without bulges noted with bearing down. Urine analysis shows WBCs and bacteria. What diagnosis of the male genitalia is most likely?
- A. Acute orchitis
- B. Acute epididymitis
- C. Torsion of the spermatic cord
- D. Prostatitis
Correct Answer: B
Rationale: The correct answer is B: Acute epididymitis. The patient's symptoms of pain in the testicle and penis, worsened pain with urination, and presence of WBCs and bacteria in the urine analysis are indicative of an infection. The severe tenderness at the superior pole of the left testicle and tenderness on palpation of structures superior to the testicle through the scrotal wall suggest involvement of the epididymis. The risk factors of multiple sexual partners and recent unprotected intercourse also support the diagnosis of epididymitis, which is commonly caused by sexually transmitted infections. Acute orchitis (choice A) typically presents with swelling and tenderness of the entire testicle, not just the epididymis. Torsion of the spermatic cord (choice C) presents with sudden onset severe testicular pain and may have a high-riding testicle. Prostatitis (choice D) presents with symptoms related to the prostate gland, such as pelvic
Which structure provides a temporary
- A. seminal gland storage site for immature sperm?
- B. tunica albuginea
- C. ductus deferens
- D. ductus deferens
Correct Answer: A
Rationale: The correct answer is A, seminal gland, which provides a temporary storage site for immature sperm. Seminal glands are responsible for producing seminal fluid which nourishes and protects the sperm. The immature sperm are stored in the seminal gland until they mature. The other choices, B tunica albuginea, is a tough layer surrounding the testes, not involved in sperm storage. C ductus deferens is a tube that transports mature sperm from the epididymis to the urethra, not for storage of immature sperm. D is a duplicate of C, so it is incorrect.
You obtain all of these assessment data about your client with continuous bladder irrigation (CBI) after a transurethral resection of the prostate (TURP). Which information indicates the most immediate need for nursing intervention?
- A. The client states he feels a continuous urge to void.
- B. The catheter drainage is light pink with occasional clots.
- C. The catheter is pulled taut and taped to the client's thigh.
- D. The client complains of painful bladder spasms.
Correct Answer: D
Rationale: Painful bladder spasms can indicate complications such as clot formation or obstruction, requiring immediate attention.
Ovulation is initiated by
- A. rising levels of follicle stimulating hormone
- B. rising levels of progesterone
- C. a drop in oestrogen levels
- D. rising levels of luteinizing hormone
Correct Answer: D
Rationale: The correct answer is D: rising levels of luteinizing hormone. Luteinizing hormone surge triggers ovulation by stimulating the release of the mature egg from the ovary. This surge is a crucial event in the menstrual cycle. A: Follicle stimulating hormone is involved in follicular development, not ovulation. B: Progesterone levels rise after ovulation, not before. C: Oestrogen levels actually rise before ovulation to trigger the LH surge, so a drop in oestrogen levels would not initiate ovulation.
