Correct Answer(s)
A. Eating small, frequent meals and avoiding fatty and spicy food
C. Drinking milk between milk
E. Sitting upright for 30 minutes after a meal
Explanation
Heartburn is a common discomfort during pregnancy due to hormonal changes and pressure on the stomach. Eating small, frequent meals helps to prevent heartburn by reducing the amount of food in the stomach at one time. Avoiding fatty and spicy foods also helps to prevent heartburn as these types of foods can trigger acid reflux. Drinking milk between meals can provide relief from heartburn as milk has a soothing effect on the stomach. Sitting upright for 30 minutes after a meal helps to prevent heartburn by allowing gravity to keep stomach acid down.

Select all the necessary measures that the nurse can provide to the patient.
Correct Answer(s)
A. Drink 2 quarts of fluid during the day
C. Performing Kegel exercises
E. Limiting fluid intake during the evening
Explanation
During pregnancy, the enlarging fetus can press on the bladder, causing urinary urgency and frequency. This is particularly common during the first and third trimesters. To prevent urinary frequency, the nurse can advise the patient to drink 2 quarts of fluid during the day to stay hydrated, perform Kegel exercises to strengthen the pelvic floor muscles and control bladder function, and limit fluid intake during the evening to reduce nighttime urination. These measures can help manage the symptoms and improve the patient's comfort during pregnancy.

Correct Answer(s)
A. Gush of vaginal discharge
B. Vaginal bleeding
C. Persistent vomiting
F. Epigastric or abdominal pain
Explanation
The client demonstrates understanding of the danger signs of pregnancy by stating the following symptoms: gush of vaginal discharge, vaginal bleeding, persistent vomiting, and epigastric or abdominal pain. These symptoms can indicate potential complications such as infection, placental problems, or preeclampsia. Constipation and urinary frequency are not typically considered danger signs of pregnancy. Fetal heart rate of 120 is within the normal range and not a danger sign.
21.
What is the recommended drug for the prevention of maternal-fetal HIV transmission; it is usually administered orally beginning after 14 weeks' gestation, intravenously during labor, and in the form of syrup to the neonate after birth for 6 weeks?
Correct Answer(s)
Zidovudine, zidovudine
Explanation
Zidovudine is the recommended drug for the prevention of maternal-fetal HIV transmission. It is usually administered orally beginning after 14 weeks' gestation to the pregnant mother, intravenously during labor, and in the form of syrup to the neonate after birth for 6 weeks. Zidovudine, also known as AZT, is an antiretroviral medication that helps reduce the risk of HIV transmission from mother to child. By taking zidovudine during pregnancy, labor, and postpartum, the viral load in the mother's blood is suppressed, reducing the chances of transmission to the fetus or newborn.
22.
A nurse is collecting data during the admission assessment of a client who is pregnant with twins. The client also has a 5-year-old child. The nurse would document which gravida and para status on this client?
Correct Answer
B. G2P1
Explanation
The correct answer is G2P1. Gravida refers to the number of pregnancies the client has had, including the current one. Para refers to the number of pregnancies that have reached viability (20 weeks or more) regardless of the outcome (live birth or stillbirth). In this case, the client is pregnant with twins, so it counts as one pregnancy (G1). The client also has a 5-year-old child, which counts as one para (P1). Therefore, the correct documentation would be G2P1.

The nurse is developing a teaching plan for a patient who is 8 weeks pregnant. The nurse should tell the patient that she can expect to feel the fetus move at which time?
Correct Answer
B. Between 16 and 20 weeks’ gestation
Explanation
A pregnant woman usually can detect fetal movement (quickening) between 16 and 20 weeks’ gestation. Before 16 weeks, the fetus is not developed enough for the woman to detect movement. After 20 weeks, the fetus continues to gain weight steadily, the lungs start to produce surfactant, the brain is grossly formed, and myelination of the spinal cord begins.
32.
A couple who wants to conceive but has been unsuccessful during the last 2 years has undergone many diagnostic procedures. When discussing the situation with the nurse, one partner states, “We know several friends in our age group and all of them have their own child already, Why can’t we have one?”.

Correct Answer
D. Self-esteem disturbance related to infertility.
Explanation
Based on the partner’s statement, the couple is verbalizing feelings of inadequacy and negative feelings about themselves and their capabilities. Thus, the nursing diagnosis of self-esteem disturbance is most appropriate. Fear, pain, and ineffective family coping also may be present but as secondary nursing diagnoses.
33.
Which of the following urinary symptoms does the pregnant woman most frequently experience during the first trimester?
Correct Answer
B. Frequency
Explanation
Pressure and irritation of the bladder by the growing uterus during the first trimester is responsible for causing urinary frequency. Dysuria, incontinence, and burning are symptoms associated with urinary tract infections.
34.
Heartburn and flatulence, common in the second trimester, are most likely the result of which of the following?
Correct Answer
C. Decrease gastric acidity
Explanation
During the second trimester, the reduction in gastric acidity in conjunction with pressure from the growing uterus and smooth muscle relaxation can cause heartburn and flatulence. HCG levels increase in the first, not the second, trimester. Decrease intestinal motility would most likely be the cause of constipation and bloating. Estrogen levels decrease in the second trimester.
35.
On which of the following areas would the nurse expect to observe chloasma?
Correct Answer
D. Cheeks, forehead, and nose
Explanation
Chloasma, also called the mask of pregnancy, is an irregular hyperpigmented area found on the face. It is not seen on the breasts, areola, nipples, chest, neck, arms, legs, abdomen, or thighs.
36.
A pregnant client states that she “waddles” when she walks. The nurse’s explanation is based on which of the following as the cause?
Correct Answer
C. Relaxation of the pelvic joints
Explanation
During pregnancy, hormonal changes cause relaxation of the pelvic joints, resulting in the typical “waddling” gait. Changes in posture are related to the growing fetus. Pressure on the surrounding muscles causing discomfort is due to the growing uterus. Weight gain has no effect on gait.
37.
Which of the following represents the average amount of weight gained during pregnancy?
Correct Answer
C. 25 to 30 lbs
Explanation
The average amount of weight gained during pregnancy is 25 to 35 lb. This weight gain consists of the following: fetus – 7.5 lb; placenta and membrane – 1.5 lb; amniotic fluid – 2 lb; uterus – 2.5 lb; breasts – 3 lb; and increased blood volume – 2 to 4 lb; extravascular fluid and fat – 4 to 9 lb. A gain of 12 to 22 lb is insufficient, whereas a weight gain of 15 to 25 lb is marginal. A weight gain of 25 to 40 lb is considered excessive.
38.
When talking with a pregnant client who is experiencing aching swollen, leg veins, the nurse would explain that this is most probably the result of which of the following?
Correct Answer
C. Pressure on blood vessels from the enlarging uterus
Explanation
The pressure of the growing uterus on blood vessels results in an increased risk for venous stasis in the lower extremities. Subsequently, edema and varicose vein formation may occur. Thrombophlebitis is an inflammation of the veins due to thrombus formation. Pregnancy-induced hypertension is not associated with these symptoms. Gravity plays only a minor role in these symptoms.
39.
Cervical softening and uterine souffle are classified as which of the following?
Correct Answer
C. Probable signs
Explanation
Cervical softening (Goodell sign) and uterine soufflé are two probable signs of pregnancy.Probable signs are objective findings that strongly suggest pregnancy. Other probable signs include Hegar sign, which is softening of the lower uterine segment; Piskacek sign, which is enlargement and softening of the uterus; serum laboratory tests; changes in skin pigmentation; and ultrasonic evidence of a gestational sac. Presumptive signs are subjective signs and include amenorrhea; nausea and vomiting; urinary frequency; breast tenderness and changes; excessive fatigue; uterine enlargement; and quickening.
40.
Which of the following would the nurse identify as a presumptive sign of pregnancy?

A client LMP began on July 5. Her EDD should be which of the following?
Correct Answer
C. April 12
Explanation
To determine the EDD when the date of the client’s LMP is known use Nagele rule. To the first day of the LMP, add 7 days, subtract 3 months, and add 1 year (if applicable) to arrive at the EDD as follows: 5 + 7 = 12 (July) minus 3 = 4 (April). Therefore, the client’s EDD is April 12.
46.
Which of the following fundal heights indicates less than 12 weeks’ gestation when the date of the LMP is unknown?
Correct Answer
A. Uterus in the pelvis
Explanation
When the LMP is unknown, the gestational age of the fetus is estimated by uterine size or position (fundal height). The presence of the uterus in the pelvis indicates less than 12 weeks’ gestation. At approximately 12 to 14 weeks, the fundus is out of the pelvis above the symphysis pubis. The fundus is at the level of the umbilicus at approximately 20 weeks’ gestation and reaches the xiphoid at term or 40 weeks.
47.
Which of the following prenatal laboratory test values would the nurse consider as significant?
Correct Answer
B. Rubella titer less than 1:8
Explanation
A rubella titer should be 1:8 or greater. Thurs, a finding of a titer less than 1:8 is significant, indicating that the client may not possess immunity to rubella. A hematocrit of 33.5% a white blood cell count of 8,000/mm3, and a 1 hour glucose challenge test of 110 g/dl are with normal parameters.
48.
The hormone responsible for the development of the ovum during the menstrual cycle is?
Correct Answer
C. Follicle stimulating hormone
Explanation
Follicle stimulating hormone (FSH) is responsible for the development of the ovum during the menstrual cycle. FSH stimulates the growth and maturation of follicles in the ovaries, which contain the eggs. As the follicles develop, they produce estrogen, which further supports the growth of the ovum. Once the ovum is fully developed, it is released from the ovary in a process called ovulation, which is triggered by a surge in luteinizing hormone (LH). Progesterone plays a role in preparing the uterus for potential pregnancy after ovulation. However, FSH is specifically responsible for the development of the ovum.
49.
During which of the following phase of the menstrual cycle is it ideal for implantation of a fertilized egg to occur?
Correct Answer
D. Secretory pHase
Explanation
The secretory phase of the menstrual cycle is the ideal time for implantation of a fertilized egg to occur. This phase occurs after ovulation and is characterized by the thickening of the uterine lining in preparation for pregnancy. During this phase, the endometrium becomes highly vascularized and glandular, providing an optimal environment for the fertilized egg to implant and develop. If implantation does not occur, the endometrium will shed during the subsequent menstrual phase.
50.
Variation on the length of menstrual cycle is due to variations in the number of days in which of the following phase?
Correct Answer
A. Proliferative pHase
Explanation
The length of the menstrual cycle can vary due to variations in the number of days in the proliferative phase. The proliferative phase is the phase of the menstrual cycle during which the lining of the uterus thickens in preparation for potential implantation of a fertilized egg. The length of this phase can vary from person to person, which in turn can affect the overall length of the menstrual cycle.
