A “birth control” compound for men has been sought for several decades. Which of the following would provide effective sterility?

  • A. Substance that mimics the actions of luteinizing hormone
  • B. Substance that blocks the actions of inhibin
  • C. Substance that blocks the actions of follicle-stimulating hormone
  • D. Substance that mimics the actions of gonadotropin-releasing hormone
Correct Answer: C

Rationale: The correct answer is C: Substance that blocks the actions of follicle-stimulating hormone. By blocking the actions of FSH, sperm production in the testes would be inhibited, leading to effective sterility. FSH plays a crucial role in stimulating sperm production, so blocking its actions would prevent the development of mature sperm.

Explanation for why the other choices are incorrect:
A: Substance that mimics the actions of luteinizing hormone - Mimicking LH would not necessarily lead to effective sterility in men.
B: Substance that blocks the actions of inhibin - Inhibin regulates FSH secretion but blocking it would not directly lead to effective sterility.
D: Substance that mimics the actions of gonadotropin-releasing hormone - Mimicking GnRH would not directly impact sperm production and sterility.

The radius, ulna and humerus forms the ___________ joint.

  • A. Knee
  • B. Elbow
  • C. Ankle
  • D. Shoulder
Correct Answer: B

Rationale: The correct answer is B: Elbow. The radius, ulna, and humerus form the elbow joint. The ulna and humerus articulate at the trochlear notch, forming the hinge joint, while the radius articulates with the humerus at the capitulum, allowing for rotation. This combination of movements allows for flexion and extension of the forearm. The other choices, knee (A), ankle (C), and shoulder (D), involve different bones and joints in the body that do not include the radius, ulna, and humerus.

A patient with testicular torsion is experiencing which abnormality?

  • A. Abnormal dilation and tortuosity of the veins along the spermatic cord
  • B. Twisting of the testicle and spermatic cord
  • C. A cystic mass filled with sperm and seminal fluid in the epididymis
  • D. An accumulation of fluid in the scrotum
Correct Answer: B

Rationale: The correct answer is B: Twisting of the testicle and spermatic cord. Testicular torsion is the twisting of the spermatic cord, leading to decreased blood flow to the testicle. This causes severe pain and swelling. Choices A, C, and D do not accurately describe the specific abnormality seen in testicular torsion. Choice A describes varicocele, choice C describes a spermatocele, and choice D describes hydrocele, which are different conditions altogether.

If bone is splintered or crushed in several places it is termed as

  • A. Complex fracture
  • B. Greenstick fracture
  • C. Impacted fracture
  • D. Comminuted fracture
Correct Answer: D

Rationale: The correct answer is D: Comminuted fracture. This type of fracture occurs when the bone is splintered or crushed in several places, leading to multiple bone fragments. This term accurately describes the situation where the bone is broken into multiple pieces.

A: Complex fracture refers to a fracture that involves multiple breaks in a bone, but not necessarily into multiple small fragments.
B: Greenstick fracture is an incomplete fracture where the bone is bent but not completely broken.
C: Impacted fracture occurs when the broken ends of the bone are driven into each other, typically seen in a fall with a lot of force, but it does not involve multiple bone fragments like in a comminuted fracture.

The ovarian follicles are located in the following structures, EXCEPT:

  • A. the Fallopian tubes;
  • B. the uterus;
  • C. the medullar area of the ovary;
  • D. the cortical area of the ovary;
Correct Answer: B

Rationale: The correct answer is B, the uterus. Ovarian follicles are structures within the ovaries where oocytes (eggs) develop. The Fallopian tubes, medullar area, and cortical area of the ovary all contain ovarian follicles. The uterus, on the other hand, is not where ovarian follicles are located; it is the organ where a fertilized egg implants and a pregnancy develops. Therefore, the correct answer is B because the uterus is not a structure where ovarian follicles are present.

The nurse is providing teaching by telephone to a patient who is scheduled for a pelvic examination and Pap test next week. The nurse instructs the patient that she should

  • A. not have sexual intercourse the day before the Pap test.
  • B. shower, but not take a tub bath, before the examination.
  • C. avoid douching for at least 24 hours before the examination.
  • D. schedule to have the Pap test just after her menstrual period
Correct Answer: C

Rationale: The correct answer is C. Douching can alter the vaginal pH and flora, affecting the accuracy of Pap test results. By avoiding douching for at least 24 hours before the exam, the patient ensures more accurate results.

A: Not having sexual intercourse the day before the Pap test is not necessary for test accuracy.
B: Showering is recommended for hygiene but taking a tub bath does not impact the test.
D: Scheduling the test just after the menstrual period may be more comfortable for the patient, but it does not affect the accuracy of the test.
