1. According to a survey by Adhikari and Liu in the year 2013, at birth, women have:
- A. close to 100,000 ova.
- B. around 300,000 to 400,000 ova.
- C. around 100 to 200 ova.
- D. only 500 ova.
Correct answer: B
Rationale: Women are born with approximately 300,000 to 400,000 ova, which gradually decrease in number as they age. Choice A ('close to 100,000 ova.') is incorrect as the actual number is much higher. Choice C ('around 100 to 200 ova.') is incorrect as it underestimates the quantity significantly. Choice D ('only 500 ova.') is incorrect as it greatly underestimates the number of ova present at birth.
2. A nurse on a labor and delivery unit is providing teaching to a client who plans to use hypnosis to control labor pain. Which of the following information should the nurse include?
- A. Focusing on controlling body functions
- B. Synchronized breathing is often helpful during hypnosis
- C. Hypnosis can be beneficial if practiced during the prenatal period
- D. Hypnosis is ineffective for controlling pain associated with labor
Correct answer: C
Rationale: Hypnosis can be an effective method of pain control during labor, especially if practiced during the prenatal period. Choice A is not specific to hypnosis and may not be directly related. Choice B is not essential for hypnosis and may not always be required. Choice D is incorrect as hypnosis has been shown to be beneficial for managing labor pain when done correctly, making it an inappropriate option to include in the teaching.
3. How many chromosomes are typically found in human cells, organized into pairs?
- A. 50
- B. 46
- C. 48
- D. 44
Correct answer: B
Rationale: Human cells typically contain 46 chromosomes organized into 23 pairs. This is the correct number for a normal human cell. Choices A, C, and D are incorrect because they do not represent the typical chromosome count in human cells.
4. Is a low sperm count or lack of sperm the most common infertility problem in men?
- A. TRUE
- B. FALSE
- C. Rarely
- D. Never
Correct answer: A
Rationale: A low sperm count or lack of sperm is indeed one of the most common causes of infertility in men. Factors such as hormonal imbalances, genetic issues, reproductive anatomy problems, and lifestyle factors can also contribute to male infertility. Choice B is incorrect because a low sperm count is a prevalent issue among men facing infertility, making it a common problem. Choices C and D are incorrect as they do not accurately reflect the prevalence of low sperm count as a cause of infertility in men.
5. _________ is self-propulsion.
- A. Mitosis
- B. Meiosis
- C. Motility

Correct answer: C
Rationale: The correct answer is 'Motility.' Motility refers to the ability of cells or organisms to move by themselves, often through the use of specialized structures like flagella or cilia. Mitosis (Choice A) and Meiosis (Choice B) are processes related to cell division and genetic recombination, respectively, not self-propulsion. Mutation (Choice D) refers to changes in the DNA sequence and is not related to self-propulsion.
