1. After meiosis, each new cell nucleus contains _____ chromosomes.

• A. 46
• B. 35
• C. 23
• D. 12

Correct answer: C

Rationale: After meiosis, each resulting cell contains 23 chromosomes. Meiosis is a process that involves two sequential divisions resulting in four daughter cells, each with half the number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes (diploid), and after meiosis, the resulting cells (sperm or ova) have 23 chromosomes (haploid). Choice A (46 chromosomes) is incorrect because this is the number of chromosomes in a human diploid cell before meiosis. Choices B (35 chromosomes) and D (12 chromosomes) are incorrect as they do not represent the correct number of chromosomes after meiosis in human cells.

2. _____ is a life-threatening disease, characterized by high blood pressure that may afflict women late in the second or early in the third trimester.

• A. Rubella
• B. Syphilis
• C. Preeclampsia
• D. Phenylketonuria

Correct answer: C

Rationale: Preeclampsia is a serious pregnancy complication characterized by high blood pressure that typically occurs in the second half of pregnancy. If left untreated, it can lead to severe complications for both the mother and the baby. Rubella (choice A) is a viral infection that can harm the developing fetus but is not directly related to high blood pressure in pregnancy. Syphilis (choice B) is a sexually transmitted infection that can affect pregnancy but does not specifically cause high blood pressure. Phenylketonuria (choice D) is a genetic disorder that affects metabolism and is not associated with high blood pressure in pregnancy.

3. The nurse has received a report regarding a client in labor. The woman’s last vaginal examination was recorded as 3 cm, 30%, and –2. What is the nurse’s interpretation of this assessment?

• A. Cervix is effaced 3 cm and dilated 30%; the presenting part is 2 cm above the ischial spines.
• B. Cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm above the ischial spines.
• C. Cervix is effaced 3 cm and dilated 30%; the presenting part is 2 cm below the ischial spines.
• D. Cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm below the ischial spines.

Correct answer: B

Rationale: The correct interpretation of the assessment provided is that the cervix is dilated 3 cm and effaced 30%; the presenting part is 2 cm above the ischial spines. In the given assessment, the measurements are ordered as dilation, effacement, and station. Choice A is incorrect as it wrongly places the presenting part below the ischial spines. Choice C is incorrect because it places the presenting part below the ischial spines. Choice D is also incorrect as it incorrectly states that the presenting part is below the ischial spines, even though it correctly mentions the dilation and effacement of the cervix.

4. During a prenatal visit, for which of the following clients should the nurse auscultate the fetal heart rate?

• A. A client who has an ultrasound confirming a molar pregnancy
• B. A client who has a crown-rump length corresponding to 7 weeks gestation
• C. A client who has a positive urine pregnancy test 1 week after missed menses
• D. A client who has felt quickening for the first time

Correct answer: D

Rationale: The correct answer is D because feeling quickening typically occurs around 18-20 weeks of gestation, indicating fetal movement. This is an appropriate time to auscultate the fetal heart rate. Choice A is incorrect because a molar pregnancy is not a viable pregnancy, and auscultating the fetal heart rate in this case is not applicable. Choice B is incorrect because a crown-rump length of 7 weeks gestation is too early for fetal heart rate auscultation. Choice C is incorrect because a positive urine pregnancy test alone does not indicate the appropriate timing for fetal heart rate auscultation.

5. Which of the following statements about Rh incompatibility is true?

• A. Rh incompatibility occurs most commonly during a woman’s first pregnancy.
• B. Rh incompatibility is an untreatable condition that leaves a woman infertile for the rest of her life.
• C. Rh incompatibility is an abnormality that is transmitted from generation to generation and carried by a sex chromosome.
• D. Rh incompatibility occurs due to antibodies transmitted to a fetus during subsequent deliveries causing brain damage or death.

Correct answer: D

Rationale: Rh incompatibility occurs when the mother's antibodies attack the fetus's red blood cells, leading to serious complications, usually in subsequent pregnancies. Choice A is incorrect because Rh incompatibility often occurs in subsequent pregnancies, not necessarily the first one. Choice B is incorrect as Rh incompatibility does not render a woman infertile but can lead to complications during pregnancies. Choice C is incorrect as Rh incompatibility is not carried by a sex chromosome but involves the Rh factor on red blood cells.
