Chapter 04_LO 01_Q01

The nurse is explaining the difference between meiosis and mitosis. Which statement would be best? Select all that apply.

1. Meiosis is the division of a cell into two exact copies of the original cell.
2. Mitosis is splitting one cell into two, each with half the chromosomes of the original cell.
3. Meiosis is the process by which gametes, or the sperm and ova, reproduce.
4. Mitosis occurs in most of the cells of the body.
5. Meiotic division leads to cells that halve the original genetic material.

Correct Answers: 3,

Rationale:

1. Meiosis creates two cells that have half of the chromosomes of the original cell.
2. Mitosis creates two cells that are exact copies of the original cell.
3. Both sperm and ova are created through meiosis.
4. Mitosis is how the majority of cells reproduce, so that the new cells have the same structure and function as the original. Meiosis only occurs in gametes.
5. Meiosis creates two cells that have half of the chromosomes of the original cell.

Chapter 04_LO2 _Q02

The nurse has completed a presentation on reproduction. Which statement indicates that the teaching has been successful?

1. “A male is born with all the sperm he will ever produce.”
2. “Females create new ova throughout their reproductive life.”
3. “Ova separate into two unequally sized cells.”
4. “Each primary spermatocyte divides into four haploid cells.”

Correct Answer:  3

Rationale:

1. Males begin spermatogenesis at puberty, and continue throughout their life. Each sperm divides into four haploid cells.
2. Females are born with all the ova they will ever produce. The ova begin to be formed in early fetal life. One ovum is released each month during the reproductive life of a female, from menarche to menopause.
3. Each ovum undergoes meiotic division just prior to being released from the graafian follicle. Each cell created by this meiosis has the same number of chromosomes, but the cytoplasm does not split equally. This causes a polar body to be produced along with a secondary oocyte.
4. Primary spermatocytes contain 46 chromosomes (46XY). Each primary spermatocyte undergoes meiotic division into two haploid secondary spermatocytes (22X or 22Y). Haploid cells each contain half of the genetic material of the original cell. Then each secondary spermatocyte undergoes a second meiotic division into two haploid spermatids (remaining either 22X or 22Y.) Spermatids mature into spermatozoa. Thus a primary spermatocyte eventually becomes four haploid spermatozoa.

Chapter 04_LO2 _Q03

The nurse is presenting information on pregnancy and fetal development. In order to evaluate learning, the nurse asks the following question: “When a female reaches adolescence, the ova continue to divide by the process of meiosis. How many chromosomes do the resulting cells then have?” What is the correct answer?

1. 46 double-structured chromosomes
2. 46 single chromosomes
3. 23 double-structured chromosomes
4. 23 single chromosomes

Answer: 3

Rationale:

1. Meiosis is the process of cells splitting their genetic material during replication. The first meiotic division of ova results in half the original number of chromosomes. The second meiotic division occurs after adolescence, and creates 23 double-structured chromosomes.
2. Meiosis is the process of cells splitting their genetic material during replication. The first meiotic division of ova results in half the original number of chromosomes. The second meiotic division occurs after adolescence, and creates 23 double-structured chromosomes.
3. Meiosis is the process of cells splitting their genetic material during replication. The first meiotic division of ova results in half the original number of chromosomes. The second meiotic division occurs after adolescence, and creates 23 double-structured chromosomes.
4. Meiosis is the process of cells splitting their genetic material during replication. The first meiotic division of ova results in half the original number of chromosomes. The second meiotic division occurs after adolescence, and creates 23 double-structured chromosomes.

Chapter 04_LO03 _Q04

The nurse is creating a handout on reproduction for teen clients. Which piece of information should the nurse include in this handout?

1. The fertilized ovum is called a gamete.
2. Prior to fertilization, the sperm are zygotes.
3. Ova survive 12–24 hours in the fallopian tube if not fertilized.
4. Sperm survive in the female reproductive tract up to a week.

Correct Answer: 3

Rationale:

1. Ova and sperm are gametes; a fertilized ovum is a zygote.
2. Sperm are gametes (as are ova); a zygote is a fertilized ovum.
3. Ova are fertile for about 12–24 hours after being released from the graafian follicle.
4. Sperm survive 48–72 hours in the female reproductive tract, but are most fertile in the first 24 hours.
