A nurse expects to find which manifestations in the male patient who has both Chlamydia and gonorrhea?

  • A. Painful urination and purulent urethral discharge
  • B. A single, firm painless open sore on the shaft of the penis
  • C. Red superficial vesicles on the shaft of the penis
  • D. A single or a cluster of wartlike growth in the anal-rectal area
Correct Answer: A

Rationale: The correct answer is A because painful urination and purulent urethral discharge are classic manifestations of both Chlamydia and gonorrhea in male patients. Painful urination, known as dysuria, is a common symptom of these sexually transmitted infections due to inflammation of the urethra. Purulent urethral discharge is also typical and results from the infection of the urethral mucosa.

Option B is incorrect as a single, firm, painless open sore on the shaft of the penis is a classic presentation of syphilis, not Chlamydia or gonorrhea. Option C is incorrect as red superficial vesicles on the shaft of the penis are characteristic of genital herpes. Option D is incorrect as a single or a cluster of wartlike growth in the anal-rectal area is typical of genital warts caused by human papillomavirus (HPV).

Which structure is the site of sperm production?

  • A. Vas deferens
  • B. Seminiferous tubules
  • C. Albuginea
  • D. Epididymis
Correct Answer: B

Rationale: The correct answer is B: Seminiferous tubules. These tubules are located within the testes and are the specific structures where sperm production occurs through a process called spermatogenesis. Sperm cells are produced within the seminiferous tubules and then mature as they move through the epididymis (choice D) and vas deferens (choice A). The albuginea (choice C) is the tough outer covering of the testes and does not play a direct role in sperm production. Therefore, the seminiferous tubules are the primary site for sperm production in the male reproductive system.

Sella turcica is a __________ in the sphenoid bone in which

  • B. Groove
  • C. Projection
  • D. Depression
Correct Answer: D

Rationale: The correct answer is D: Depression. Sella turcica is a saddle-shaped depression in the sphenoid bone that houses the pituitary gland. It is not a groove (B) as it is a deeper concavity. It is not a projection (C) as it is a recessed area rather than a raised structure. It is not a foramen (A) as it is a hollowed-out area rather than a small opening. Therefore, the most accurate description of sella turcica is a depression in the sphenoid bone.

A client with the herpes simplex virus type 2 (HSV-2) undergoes a viral shedding. Which of the following statements is true when caring for a client with HSV-2?

  • A. An outbreak of the HSV-2 infection is often self-limiting and hence a treatment may be unnecessary.
  • B. Clients don't seek treatment because of embarrassment.
  • C. Healthcare providers and laboratories are not required by law to report.
  • D. Reporting is up to the client, not the provider.
Correct Answer: A

Rationale: HSV-2 outbreaks are often self-limiting, though antiviral medications can help manage symptoms.

The deferent duct joins with the ........ and forms.........:

  • A. the seminal vesicle duct;
  • B. the urethra;
  • C. the ejaculatory duct;
  • D. the epididymal duct;
Correct Answer: C

Rationale: The correct answer is C: the ejaculatory duct. The deferent duct, also known as the vas deferens, joins with the seminal vesicle duct to form the ejaculatory duct. This is where sperm from the testes and fluid from the seminal vesicles combine before entering the urethra during ejaculation. The other choices are incorrect because the seminal vesicle duct does not directly join with the deferent duct, the urethra is not formed by the deferent duct, and the epididymal duct is not involved in the formation of the ejaculatory duct.

Regarding respiratory system of fetus

  • A. Respiratory bud starts to appear at the ventral wall of foregut at approximately week 10 of gestation
  • B. There are 4 stages of development of respiratory system
  • C. Development of respiratory tract is not complete until the last week of fetal development.
  • D. Epithelial respiratory is derived from endodermal
Correct Answer: A

Rationale: The correct answer is A because the respiratory bud does indeed start to appear at the ventral wall of the foregut around week 10 of gestation. This marks the beginning of respiratory system development. Choice B is incorrect as there are actually 5 stages of respiratory system development. Choice C is also incorrect as the development of the respiratory tract is not fully complete until after birth, not just in the last week of fetal development. Choice D is incorrect because the epithelial respiratory lining is derived from endoderm, not endodermal.
