Nokea
Which of the following statements is incorrect.
- A. a female has approximately 2-4 million oocytes at birth
- B. a female has approximately 6 million oogonia during fetal development
- C. a female ovulates about 2,000 to 4,000 oocytes during her life
- D. only approximately 1-5 oocytes are fertilized
Correct Answer: C
Rationale: The correct answer is C because a female actually ovulates only about 400-500 oocytes during her lifetime, not 2,000 to 4,000. This is due to the process of follicular atresia where many oocytes are lost before ovulation. Choice A is correct as females have a finite number of oocytes at birth. Choice B is correct as oogonia differentiate into primary oocytes during fetal development. Choice D is incorrect as typically only one oocyte is fertilized during each menstrual cycle.

The nurse will plan to teach a 51-yr-old man who is scheduled for an annual physical examination about a(n)
- A. increased risk for testicular cancer.
- B. possible changes in erectile function.
- C. normal decreases in testosterone level.
- D. prostate specific antigen (PSA) testing.
Correct Answer: C
Rationale: The correct answer is C: normal decreases in testosterone level. At the age of 51, it is important to educate the man about the normal age-related decline in testosterone levels, which can affect various aspects of health. This information will help manage expectations and address potential symptoms. Option A is incorrect as testicular cancer risk typically decreases with age. Option B may be a concern but is not the primary focus of education for a routine physical exam. Option D (PSA testing) is more relevant for prostate health, which is not the main focus of education for a 51-year-old man's annual physical exam.
Which of the following is responsible for secondary sex characteristics in females?
- A. Estrogens
- B. Progesterone
- C. Follicl
- D. stimulating hormone (FSH)
Correct Answer: A
Rationale: Estrogens are responsible for secondary sex characteristics in females as they promote breast development, regulate the menstrual cycle, and contribute to the distribution of body fat. Progesterone mainly prepares the uterus for pregnancy. Follicle-stimulating hormone (FSH) plays a role in the development of ovarian follicles and the maturation of eggs but does not directly influence female secondary sex characteristics.
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.
At what point in life does a female begin her monthly ovarian cycle?
- A. At birth
- B. At puberty
- C. At middle age
- D. At menopause
Correct Answer: B
Rationale: The correct answer is B: At puberty. The monthly ovarian cycle, also known as the menstrual cycle, begins at puberty when a female's body matures and starts ovulating. This is typically around the age of 11-14. At birth (A), females already have all their eggs but do not start ovulating until puberty. Middle age (C) refers to the period around 40-65, which is not when the cycle begins. Menopause (D) is the cessation of the menstrual cycle, marking the end of reproductive years, typically around the age of 45-55.

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