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).
What factor will inhibit LH secretion?
- A. FSH
- B. progesterone
- C. estrogen
- D. LH
Correct Answer: B
Rationale: The correct answer is B: progesterone. Progesterone inhibits LH secretion by exerting negative feedback on the hypothalamus and pituitary gland. This hormone signals that the body has enough progesterone and does not need additional LH for ovulation. FSH (choice A) stimulates LH secretion, estrogen (choice C) typically increases LH secretion during the menstrual cycle, and LH (choice D) does not inhibit its own secretion.
Each menstrual cycle is considered as a period of ________
- A. 28 days
- B. 30 days
- C. 42 days
- D. 14 days
Correct Answer: A
Rationale: The correct answer is A: 28 days because the average menstrual cycle length is typically around 28 days, although it can vary. The menstrual cycle consists of different phases such as menstruation, follicular phase, ovulation, and luteal phase, which collectively last around 28 days on average. Choice B (30 days), C (42 days), and D (14 days) are incorrect because they do not represent the typical duration of a menstrual cycle. It's important to note that individual variations in cycle length are common, but 28 days is considered a standard reference point.
