Sexual feelings are normal and necessary

  • A. for reproduction to occur
  • B. for the heart and lungs to function properly
  • C. for an ovum to be released from a female’s ovary each month
  • D. for teens to become adults
Correct Answer: A

Rationale: The correct answer is A because sexual feelings are indeed necessary for reproduction to occur. Sexual arousal and desire play a vital role in initiating the process of conception and ensuring the continuation of the human species. Without sexual feelings, procreation would not be possible.

Explanation for why the other choices are incorrect:
B: Sexual feelings are not necessary for the heart and lungs to function properly. These bodily functions are regulated by the autonomic nervous system, not by sexual arousal.
C: While sexual feelings can influence the release of an ovum during ovulation, they are not the sole factor. Ovulation can occur without sexual arousal.
D: Sexual feelings are not a requirement for teenagers to become adults. Puberty and the physical and emotional changes that come with it mark the transition from adolescence to adulthood, not sexual feelings.

For fertilization to be accomplished, of the secondary sex characteristics sperm release enzymes to break seen in young women? down the corona radiata from their

  • A. enlargement of the accessory ________.
  • B. mitochondria
  • C. breast development
  • D. acrosomes
Correct Answer: D

Rationale: The correct answer is D: acrosomes. Acrosomes are specialized vesicles in the head of the sperm that contain enzymes to help the sperm penetrate the outer layer of the egg during fertilization. Enlargement of the accessory organs (choice A), mitochondria (choice B), and breast development (choice C) are not directly related to the process of fertilization and do not involve the release of enzymes to break down the corona radiata. Acrosomes play a crucial role in the fertilization process by facilitating the penetration of the egg's protective layers, making choice D the correct answer.

The tiny female sex cell that unites with male sperm to form a zygote or fertilized egg.

  • A. Ovary
  • B. Ovum
  • C. Gonad
  • D. Gamets
Correct Answer: B

Rationale: The correct answer is B: Ovum. The ovum is the mature female sex cell that unites with a male sperm during fertilization to form a zygote. Ovary (A) is the organ that produces eggs but is not the actual female sex cell. Gonad (C) is a general term for reproductive organs, not the specific female sex cell. Gametes (D) refer to both male and female sex cells, so it is a broad term and not the specific female sex cell. The ovum is the only choice that accurately represents the tiny female sex cell involved in fertilization.

Advanced breast cancer often metastasizes to the bone. If this occurs, a prudent nursing measure would be to

  • A. encourage a diet high in calcium
  • B. caution the patient against falling, reaching, twisting, or lifting heavy objects
  • C. encourage the patient to abstain from sexual intercourse
  • D. caution the patient about using any pain medication
Correct Answer: B

Rationale: Preventing falls and injuries is crucial in patients with bone metastasis due to increased fracture risk.

Regarding histology of male reproductive system

  • A. Leydig cells are found in the seminiferous tubule
  • B. Sertoli cells are involved in maturation of spermatids.
  • C. The luminal epithelium of efferent ductules is irregular.
  • D. Contraction of smooth muscle in vas deferens is stimulated via sympathetic
Correct Answer: C

Rationale: The correct answer is C because the luminal epithelium of efferent ductules is indeed irregular, which helps in absorption and modification of fluid. A, Leydig cells are located outside the seminiferous tubule. B, Sertoli cells provide nourishment and support to developing sperm cells but do not mature spermatids. D, Contraction of smooth muscle in vas deferens is stimulated by the parasympathetic nervous system, not the sympathetic.

After arriving for your shift in the emergency department (ED), you receive change-of-shift report about all of these clients. Which one do you need to assess first?

  • D. A 77-year-old client with abdominal pain and acute bladder distention.
Correct Answer: A

Rationale: Severe scrotal pain unrelieved by elevation suggests testicular torsion, a urologic emergency.
