1. What is a procedure for using ultrasonic sound waves to create a picture of an embryo or fetus?

• A. Phenotype
• B. Sonogram
• C. Genotype
• D. Alpha-fetoprotein (AFP) assay

Correct answer: B

Rationale: A sonogram, also known as an ultrasound, is a procedure that utilizes sound waves to generate images of a developing embryo or fetus. This imaging technique is commonly used in prenatal care to monitor fetal development and identify any potential abnormalities. Choices A, C, and D are incorrect because a phenotype refers to an individual's observable traits resulting from genetic and environmental influences, a genotype is an individual's genetic makeup, and an alpha-fetoprotein (AFP) assay is a blood test used to screen for certain birth defects.

2. A client has bacterial vaginosis. Which of the following medications should the nurse expect to administer?

• A. Metronidazole
• B. Fluconazole
• C. Acyclovir
• D. Clindamycin

Correct answer: A

Rationale: Metronidazole is the correct choice for treating bacterial vaginosis as it is the first-line medication recommended for this condition. Metronidazole works by disrupting the DNA structure of bacteria, making it an effective treatment. Choice B, Fluconazole, is an antifungal medication primarily used for treating fungal infections, not bacterial vaginosis. Choice C, Acyclovir, is an antiviral medication used to treat viral infections, not bacterial vaginosis. Choice D, Clindamycin, is also used to treat bacterial infections but is not the first-line treatment for bacterial vaginosis, making it an incorrect choice in this scenario.

3. A client tells the nurse that she thinks she's pregnant. Which signs or symptoms provide the best indication that the client is pregnant?

• A. Morning sickness.
• B. Breast tenderness.
• C. Amenorrhea.
• D. Hegar's sign.

Correct answer: D

Rationale: Hegar's sign, which is a softening of the lower uterine segment, is considered a probable sign of pregnancy as it indicates changes in the cervix and uterus that occur during pregnancy. Amenorrhea, the absence of menstruation, is a common early sign of pregnancy but can also be due to other factors. Morning sickness, nausea and vomiting, can be a sign of early pregnancy but is not as specific as Hegar's sign. Breast tenderness is a common symptom in early pregnancy due to hormonal changes, but it is not as definitive as Hegar's sign in indicating pregnancy.

4. A client who is receiving prenatal care is at her 24-week appointment. Which of the following laboratory tests should the nurse plan to conduct?

• A. Group B strep culture
• B. 1-hour glucose tolerance test
• C. Rubella titer
• D. Blood type and Rh

Correct answer: B

Rationale: The correct answer is B: 1-hour glucose tolerance test. At around 24-28 weeks of gestation, a pregnant individual is typically screened for gestational diabetes. The 1-hour glucose tolerance test helps in identifying elevated blood sugar levels during pregnancy. Choice A, Group B strep culture, is not typically performed at the 24-week appointment but later in the third trimester to screen for Group B streptococcus colonization. Choice C, Rubella titer, is usually checked early in pregnancy to determine immunity to rubella. Choice D, Blood type and Rh, is important for determining the client's blood type and Rh status, but it is usually done earlier in pregnancy and not specifically at the 24-week appointment.

5. A primigravida arrives at the observation unit of the maternity unit because she thinks she is in labor. The nurse applies the external fetal heart monitor and determines that the fetal heart rate is 140 beats per minute and contractions are occurring irregularly every 10 to 15 minutes. Which assessment finding confirms to the nurse that the client is not in labor at this time?

• A. Membranes are intact.
• B. 2+ pitting edema in lower extremities.
• C. Contractions decrease with walking.
• D. Cervical dilation is 1 centimeter.

Correct answer: C

Rationale: The correct answer is C. Contractions that decrease with walking are typically indicative of false labor, as true labor contractions tend to intensify with activity. Choices A, B, and D are incorrect. A) Intact membranes are a normal finding and do not confirm the absence of labor. B) 2+ pitting edema in lower extremities is a sign of fluid retention and not directly related to labor status. D) Cervical dilation of 1 centimeter indicates some cervical changes, but it alone does not confirm active labor.
