Select the correct statements regarding the ovary:
- A. it is covered on the surface by a simple epithelium;
- B. it displays the glandular parenchyma on the inside;
- C. it contains follicles at various stages of development;
- D. it connects by ligaments to the Fallopian tube;
Correct Answer: B
Rationale: The correct statement is B: it displays the glandular parenchyma on the inside. The ovary contains specialized tissue called parenchyma, which consists of follicles that house the ova (eggs). This glandular tissue is responsible for producing hormones like estrogen and progesterone.
Rationale:
- A is incorrect because the ovary is actually covered by a specialized epithelial layer called the germinal epithelium, not a simple epithelium.
- C is incorrect because while the ovary does contain follicles at various stages of development, this alone does not encompass the entire function or structure of the ovary.
- D is incorrect because the ovary is connected to the Fallopian tube via the infundibulopelvic ligament, not directly by ligaments.

A nurse is called to the playground near her house in relation to an adolescent who experienced intense pain in his testicle after riding his bike. The nurse suspects which of the following problems has occurred?
- A. Torsion of the spermatic cord
- B. Cryptorchidism
- C. Phimosis

Correct Answer: A
Rationale: Testicular torsion presents with sudden, severe pain and requires immediate medical attention.
Infertility could develop when the sperm cells display _____.
- A. a count of 120 million per ml semen
- B. increased acrosomal activity
- C. normal morphology
- D. a count of less than 20 million per ml semen
Correct Answer: D
Rationale: The correct answer is D because a low sperm count (less than 20 million per ml semen) can lead to infertility as it decreases the chances of successful fertilization. A high sperm count (choice A) is actually beneficial for fertility. Increased acrosomal activity (choice B) can enhance fertilization potential. Normal morphology (choice C) refers to the shape and size of sperm, which is important for fertility but not the primary factor in infertility due to low sperm count. Overall, a low sperm count is the most significant factor in infertility.
Which question should the nurse ask when assessing a 60-yr-old patient who has a history of benign prostatic hyperplasia (BPH)?
- A. “Have you noticed any unusual discharge from your penis?”
- B. “Has there been any change in your sex life in the past year?”
- C. “Has there been a decrease in the force of your urinary stream?”
- D. “Have you been experiencing any difficulty in achieving an erection?”
Correct Answer: C
Rationale: The correct question to ask when assessing a 60-yr-old patient with a history of BPH is C: “Has there been a decrease in the force of your urinary stream?” This question is relevant as BPH commonly causes urinary symptoms like weak urinary stream. Asking about unusual discharge (A) is more relevant for assessing sexually transmitted infections. Inquiring about changes in sex life (B) and difficulty achieving an erection (D) are more related to erectile dysfunction, which may not be directly linked to BPH in this context.
A patient comes in having had repeated colds and infections. Problems in his ear are shown to be due to accumulation of fluid in the middle ear. This is due to a blockage of the:
- A. Saccule
- B. Utricle
- C. External ear
- D. Eustachian tube
Correct Answer: D
Rationale: The correct answer is D: Eustachian tube. The Eustachian tube connects the middle ear to the back of the nose and throat, helping to equalize air pressure and drain fluid from the middle ear. Blockage of the Eustachian tube can lead to fluid accumulation in the middle ear, causing ear problems. The other choices, A: Saccule and B: Utricle, are structures in the inner ear related to balance and hearing, not fluid drainage. Choice C: External ear, refers to the outer ear structures and is not involved in middle ear fluid accumulation.
A man suffers from a disease that destroyed only the motor neurons of the spinal cord below the thoracic region. Which aspect of sexual function would not be possible?
- A. Arousal
- B. Erection
- C. Lubrication
- D. Ejaculation
Correct Answer: D
Rationale: The correct answer is D: Ejaculation. Motor neurons control muscle movements, including those involved in ejaculation. Since the motor neurons below the thoracic region are damaged, the man would not be able to ejaculate. Arousal (A), erection (B), and lubrication (C) are controlled by different mechanisms and do not solely rely on motor neurons in the spinal cord.
