HESI OB QUESTIONS BANK (Orange Book)

HESI OB QUESTIONS BANK (Orange Book) 184. The nurse is preparing to teach a prenatal class about fetal circulation. Which statements should be included in the teaching plan? Select all that apply. 1. “The ductus arteriosus allows blood to bypass the fetal lungs.” 2. “One vein carries oxygenated blood from the placenta to the fetus.” 3. “The normal fetal heart beat range is 160 to 180 beats per minute in pregnancy.” 4. “Two arteries carry deoxygenated blood and waste products away from the fetus to the placenta.” 5. “Two veins carry blood that is high in carbon dioxide and other waste products away from the fetus to the placenta.” Rationale: The ductus arteriosus is a unique fetal circulation structure that allows blood to bypass the nonfunctioning fetal lungs. Oxygenated blood is transported to the fetus by one umbilical vein. The normal fetal heart beat range is considered to be 110 to 160 beats per minute. Two arteries carry deoxygenated blood and waste products from the fetus, and one umbilical vein carries oxygenated blood and provides oxygen and nutrients to the fetus. Blood pumped by the embryo’s heart leaves the embryo through two umbilical arteries. 185. The nursing instructor asks the student to describe fetal circulation, specifically the ductus venosus. Which statement by the student indicates an understanding of the ductus venosus? 1. “It connects the pulmonary artery to the aorta.” 2. “It is an opening between the right and left atria.” 3. “It connects the umbilical vein to the inferior vena cava.” 4. “It connects the umbilical artery to the inferior vena cava.” Rationale: The ductus venosus connects the umbilical vein to the inferior vena cava. The foramen ovale is a temporary opening between the right and left atria. The ductus arteriosus joins the aorta and the pulmonary artery. 186. A pregnant client tells the clinic nurse that she wants to know the sex of her baby as soon as it can be determined. The nurse informs the client that she should be able to find out the sex at 16 weeks’ gestation because of which factor? 1. The appearance of the fetal external genitalia 2. The beginning of differentiation in the fetal groin 3. The fetal testes are descended into the scrotal sac 4. The internal differences in males and females become apparent 187. The nurse is performing an assessment on a client who is at 38 weeks’ gestation and notes that the fetal heart rate (FHR) is 174 beats per minute. On the basis of this finding, what is the priority nursing action? 1. Document the finding. 2. Check the mother’s heart rate. 3. Notify the obstetrician (OB). 4. Tell the client that the fetal heart rate is normal. Rationale: The FHR depends on gestational age and ranges from 160 to 170 beats per minute in the first trimester but slows with fetal growth to 110 to 160 beats per minute. If the FHR is less than 110 beats per minute or more than 160 beats per minute with the uterus at rest, the fetus may be in distress. Because the FHR is increased from the reference range, the nurse should notify the OB. Options 2 and 4 are inappropriate actions based on the information in the question. Although the nurse documents the findings, based on the information in the question, the OB needs to be notified. 188. The nurse is conducting a prenatal class on the female reproductive system. When a client in the class asks why the fertilized ovum stays in the fallopian tube for 3 days, what is the nurse’s best response? 1. “It promotes the fertilized ovum’s chances of survival.” 2. “It promotes the fertilized ovum’s exposure to estrogen and progesterone.” 3. “It promotes the fertilized ovum’s normal implantation in the top portion of the uterus.” 4. “It promotes the fertilized ovum’s exposure to luteinizing hormone and follicle-stimulating hormone.” 189. The nursing instructor asks a nursing student to explain the characteristics of the amniotic fluid. The student responds correctly by explaining which as characteristics of amniotic fluid? Select all that apply. 1. Allows for fetal movement 2. Surrounds, cushions, and protects the fetus 3. Maintains the body temperature of the fetus 4. Can be used to measure fetal kidney function 5. Prevents large particles such as bacteria from passing to the fetus - PLACENTA 6. Provides an exchange of nutrients and waste products between the mother and the fetus - PLACENTA 190. A couple comes to the family planning clinic and asks about sterilization procedures. Which question by the nurse should determine whether this method of family planning would be most appropriate? 1. “Have you ever had surgery?” 2. “Do you plan to have any other children?” 3. “Do either of you have diabetes mellitus?” 4. “Do either of you have problems with high blood pressure?” 191. The nurse should make which statement to a pregnant client found to have a gynecoid pelvis? 1. “Your type of pelvis has a narrow pubic arch.” 2. “Your type of pelvis is the most favorable for labor and birth.” 3. “Your type of pelvis is a wide pelvis, but it has a short diameter.” 4. “You will need a cesarean section because this type of pelvis is not favorable for a vaginal delivery.” Rationale: A gynecoid pelvis is a normal female pelvis and is the most favorable for successful labor and birth. An android pelvis (resembling a male pelvis) would be unfavorable for labor because of the narrow pelvic planes. An anthropoid pelvis has an outlet that is adequate, with a normal or moderately narrow pubic arch. A platypelloid pelvis (flat pelvis) has a wide transverse diameter, but the anteroposterior diameter is short, making the outlet inadequate. 192. Which purposes of placental functioning should the nurse include in a prenatal class? Select all that apply. 1. It cushions and protects the baby. 2. It maintains the temperature of the baby. 3. It is the way the baby gets food and oxygen. 4. It prevents all antibodies and viruses from passing to the baby. 5. It provides an exchange of nutrients and waste products between the mother and developing fetus. Rationale: The placenta provides an exchange of oxygen, nutrients, and waste products between the mother and the fetus. The amniotic fluid surrounds, cushions, and protects the fetus and maintains the body temperature of the fetus. Nutrients, medications, antibodies, and viruses can pass through the placenta. 193. A 55-year-old male client confides in the nurse that he is concerned about his sexual function. What is the nurse’s best response? 1. “How often do you have sexual relations?” 2. “Please share with me more about your concerns.” 3. “You are still young and have nothing to be concerned about.” 4. “You should not have a decline in testosterone until you are in your 80s.” Prenatal Period 194. The nurse is providing instructions to a pregnant client who is scheduled for an amniocentesis. What instruction should the nurse provide? 1. Strict bed rest is required after the procedure. 2. Hospitalization is necessary for 24 hours after the procedure. 3. An informed consent needs to be signed before the procedure. 4. A fever is expected after the procedure because of the trauma to the abdomen. Rationale: Because amniocentesis is an invasive procedure, informed consent needs to be obtained before the procedure. After the procedure, the client is instructed to rest, but may resume light activity after the cramping subsides. The client is instructed to keep the puncture site clean and to report any complications, such as chills, fever, bleeding, leakage of fluid at the needle insertion site, decreased fetal movement, uterine contractions, or cramping. Amniocentesis is an outpatient procedure and may be done in the obstetrician’s office or in a special prenatal testing unit. Hospitalization is not necessary after the procedure. 195. A pregnant client in the first trimester calls the nurse at a health care clinic and reports that she has noticed a thin, colorless vaginal drainage. The nurse should make which statement to the client? 1. “Come to the clinic immediately.” 2. “The vaginal discharge may be bothersome, but is a normal occurrence.” 3. “Report to the emergency department at the maternity center immediately.” 4. “Use tampons if the discharge is bothersome, but be sure to change the tampons every 2 hours.” Rationale: Leukorrhea begins during the first trimester. Many clients notice a thin, colorless, or yellow vaginal discharge throughout pregnancy. Some clients become distressed about this condition, but it does not require that the client report to the health care clinic or emergency department immediately. If vaginal discharge is profuse, the client may use panty liners, but she should not wear tampons because of the risk of infection. If the client uses panty liners, she should change them frequently. 196. A nonstress test is performed on a client who is pregnant, and the results of the test indicate nonreactive findings. The primary health care provider prescribes a contraction stress test, and the results are documented as negative. How should the nurse document this finding? 1. A normal test result 2. An abnormal test result 3. A high risk for fetal demise 4. The need for a cesarean section Rationale: Contraction stress test results may be interpreted as negative (normal), positive (abnormal), or equivocal. A negative test result indicates that no late decelerations occurred in the fetal heart rate, although the fetus was stressed by 3 contractions of at least 40 seconds’ duration in a 10-minute period. Options 2, 3, and 4 are incorrect interpretations. 197. A rubella titer result of a 1-day postpartum client is less than 1:8, and a rubella virus vaccine is prescribed to be administered before discharge. The nurse provides which information to the client about the vaccine? Select all that apply. 1. Breast-feeding needs to be stopped for 3 months. 2. Pregnancy needs to be avoided for 1 to 3 months. 3. The vaccine is administered by the subcutaneous route. 4. Exposure to immunosuppressed individuals needs to be avoided. 5. A hypersensitivity reaction can occur if the client has an allergy to eggs. 6. The area of the injection needs to be covered with a sterile gauze for 1 week. Rationale: Rubella vaccine is administered to women who have not had rubella or women who are not serologically immune. The vaccine may be administered in the immediate postpartum period to prevent the possibility of contracting rubella in future pregnancies. The live attenuated rubella virus is not communicable in breast milk; breast-feeding does not need to be stopped. The client is counseled not to become pregnant for 1 to 3 months after immunization or as specified by the obstetrician because of a possible risk to a fetus from the live virus vaccine; the client must be using effective birth control at the time of the immunization. The client should avoid contact with immunosuppressed individuals because of their low immunity toward live viruses and because the virus is shed in the urine and other body fluids. The vaccine is administered by the subcutaneous route. A hypersensitivity reaction can occur if the client has an allergy to eggs because the vaccine is made from duck eggs. There is no useful or necessary reason for covering the area of the injection with a sterile gauze. 198. The nurse in a health care clinic is instructing a pregnant client how to perform “kick counts.” Which statement by the client indicates a need for further instruction? 1. “I will record the number of movements or kicks.” 2. “I need to lie flat on my back to perform the procedure.” 3. “If I count fewer than 10 kicks in a 2-hour period, I should count the kicks again over the next 2 hours.” 4. “I should place my hands on the largest part of my abdomen and concentrate on the fetal movements to count the kicks.” Rationale: The client should sit or lie quietly on her side to perform kick counts. Lying flat on the back is not necessary to perform this procedure, can cause discomfort, and presents a risk of vena cava (supine hypotensive) syndrome. The client is instructed to place her hands on the largest part of the abdomen and concentrate on the fetal movements. The client records the number of movements felt during a specified time period. The client needs to notify the primary health care provider (PHCP) if she feels fewer than 10 kicks over two consecutive 2-hour intervals or as instructed by the PHCP. 199. The nurse is performing an assessment of a pregnant client who is at 28 weeks of gestation. The nurse measures the fundal height in centimeters and notes that the fundal height is 30 cm. How should the nurse interpret this finding? 1. The client is measuring large for gestational age. 2. The client is measuring small for gestational age. 3. The client is measuring normal for gestational age. 4. More evidence is needed to determine size for gestational age. Rationale: During the second and third trimesters (weeks 18 to 30), fundal height in centimeters approximately equals the fetus’s age in weeks ± 2 cm. Therefore, if the client is at 28 weeks’ gestation, a fundal height of 30 cm would indicate that the client is measuring normal for gestational age. At 16 weeks, the fundus can be located halfway between the symphysis pubis and the umbilicus. At 20 to 22 weeks, the fundus is at the umbilicus. At 36 weeks, the fundus is at the xiphoid process. 200. The nurse is performing an assessment on a client who suspects that she is pregnant and is checking the client for probable signs of pregnancy. The nurse should assess for which probable signs of pregnancy? Select all that apply. 1. Ballottement 2. Chadwick’s sign 3. Uterine enlargement 4. Positive pregnancy test 5. Fetal heart rate detected by a nonelectronic device 6. Outline of fetus via radiography or ultrasonography Rationale: The probable signs of pregnancy include uterine enlargement, Hegar’s sign (compressibility and softening of the lower uterine segment that occurs at about week 6), Goodell’s sign (softening of the cervix that occurs at the beginning of the second month), Chadwick’s sign (violet coloration of the mucous membranes of the cervix, vagina, and vulva that occurs at about week 4), ballottement (rebounding of the fetus against the examiner’s fingers on palpation), Braxton Hicks contractions, and a positive pregnancy test for the presence of human chorionic gonadotropin. Positive signs of pregnancy include fetal heart rate detected by electronic device (Doppler transducer) at 10 to 12 weeks and by nonelectronic device (fetoscope) at 20 weeks of gestation, active fetal movements palpable by the examiner, and an outline of the fetus by radiography or ultrasonography. 201. A pregnant client is seen for a regular prenatal visit and tells the nurse that she is experiencing irregular contractions. The nurse determines that she is experiencing Braxton Hicks contractions. On the basis of this finding, which nursing action is appropriate? 1. Contact the primary health care provider. 2. Instruct the client to maintain bed rest for the remainder of the pregnancy. 3. Inform the client that these contractions are common and may occur throughout the pregnancy. 4. Call the maternity unit and inform them that the client will be admitted in a preterm labor condition. 202. A client arrives at the clinic for the first prenatal assessment. She tells the nurse that the first day of her last normal menstrual period was October 19, 2020. Using Näegele’s rule, which expected date of delivery should the nurse document in the client’s chart? 1. July 12, 2021 2. July 26, 2021 3. August 12, 2021 4. August 26, 2021 first day of the last menstrual period, October 19, 2020; subtract 3 months, July 19, 2020; add 7 days, July 26, 2020; add 1 year, July 26, 2021. 203. The nurse is collecting data during an admission assessment of a client who is pregnant with twins. The client has a healthy 5-year-old child who was delivered at 38 weeks and tells the nurse that she does not have a history of any type of abortion or fetal demise. Using GTPAL, what should the nurse document in the client’s chart? 1. G = 3, T = 2, P = 0, A = 0, L = 1 2. G = 2, T = 1, P = 0, A = 0, L = 1 3. G = 1, T = 1, P = 1, A = 0, L = 1 4. G = 2, T = 0, P = 0, A = 0, L = 1 Rationale: Pregnancy outcomes can be described with the acronym GTPAL. G is gravidity, the number of pregnancies; T is term births, the number born at term (longer than 37 weeks); P is preterm births, the number born before 37 weeks of gestation; A is abortions or miscarriages, the number of abortions or miscarriages (included in gravida if before 20 weeks of gestation; included in parity [number of births] if past 20 weeks of gestation); and L is the number of current living children. A woman who is pregnant with twins and has a child has a gravida of 2. Because the child was delivered at 38 weeks, the number of term births is 1, and the number of preterm births is 0. The number of abortions is 0, and the number of living children is 1. Risk conditions related to pregnancy 204. The nurse is providing instructions to a pregnant client with human immunodeficiency virus (HIV) infection regarding care to the newborn after delivery. The client asks the nurse about the feeding options that are available. Which response should the nurse make to the client? 1. “You will need to bottle-feed your newborn.” 2. “You will need to feed your newborn by nasogastric tube feeding.” 3. “You will be able to breast-feed for 6 months and then will need to switch to bottle-feeding.” 4. “You will be able to breast-feed for 9 months and then will need to switch to bottle-feeding.” 205. The home care nurse visits a pregnant client who has a diagnosis of preeclampsia. Which assessment finding indicates a worsening of the preeclampsia and the need to notify the primary health care provider (PHCP)? 1. Urinary output has increased. 2. Dependent edema has resolved. 3. Blood pressure reading is at the prenatal baseline. 4. The client complains of a headache and blurred vision. 206. A stillborn baby was delivered in the birthing suite a few hours ago. After the delivery, the family remained together, holding and touching the baby. Which statement by the nurse would assist the family in their period of grief? 1. “What can I do for you?” 2. “Now you have an angel in heaven.” 3. “Don’t worry, there is nothing you could have done to prevent this from happening.” 4. “We will see to it that you have an early discharge so that you don’t have to be reminded of this experience.” 207. The nurse implements a teaching plan for a pregnant client who is newly diagnosed with gestational diabetes mellitus. Which statement made by the client indicates a need for further teaching? 1. “I should stay on the diabetic diet.” 2. “I should perform glucose monitoring at home.” 3. “I should avoid exercise because of the negative effects on insulin production.” 4. “I should be aware of any infections and report signs of infection immediately to my obstetrician.” Rationale: Exercise is safe for a client with gestational diabetes mellitus and is helpful in lowering the blood glucose level. Dietary modifications are the mainstay of treatment, and the client is placed on a standard diabetic diet. Many clients are taught to perform blood glucose monitoring. If the client is not performing the blood glucose monitoring at home, it is performed at the clinic or obstetrician’s office. Signs of infection need to be reported to the obstetrician. 208. The nurse is performing an assessment on a pregnant client in the last trimester with a diagnosis of preeclampsia. The nurse reviews the assessment findings and determines that which finding is most closely associated with a complication of this diagnosis? 1. Enlargement of the breasts 2. Complaints of feeling hot when the room is cool 3. Periods of fetal movement followed by quiet periods 4. Evidence of bleeding, such as in the gums, petechiae, and purpura Rationale: Severe preeclampsia can trigger disseminated intravascular coagulation (DIC) because of the widespread damage to vascular integrity. Bleeding is an early sign of DIC and should be reported to the primary health care provider if noted on assessment. Options 1, 2, and 3 are normal occurrences in the last trimester of pregnancy. 209. The nurse in a maternity unit is reviewing the clients’ records. Which clients should the nurse identify as being at the most risk for developing disseminated intravascular coagulation (DIC)? Select all that apply. 1. A primigravida with abruptio placenta 2. A primigravida who delivered a 10-lb infant 3 hours ago 3. A gravida 2 who has just been diagnosed with dead fetus syndrome 4. A gravida 4 who delivered 8 hours ago and has lost 500 mL of blood 5. A primigravida at 29 weeks of gestation who was recently diagnosed with gestational hypertension Rationale: In a pregnant client, DIC is a condition in which the clotting cascade is activated, resulting in the formation of clots in the microcirculation. Predisposing conditions include abruptio placentae, amniotic fluid embolism, gestational hypertension, HELLP syndrome, intrauterine fetal death, liver disease, sepsis, severe postpartum hemorrhage, and blood loss. Delivering a large newborn is not considered a risk factor for DIC. Hemorrhage is a risk factor for DIC; however, a loss of 500 mL is not considered hemorrhage. 210. The home care nurse is monitoring a pregnant client who is at risk for preeclampsia. At each home care visit, the nurse assesses the client for which sign of preeclampsia? 1. Hypertension 2. Low-grade fever 3. Generalized edema 4. Increased pulse rate Rationale: A sign of preeclampsia is persistent hypertension. A low-grade fever or increased pulse rate is not associated with preeclampsia. Generalized edema may occur but is not a specific sign of preeclampsia because it can occur in many conditions. 211. The nurse is assessing a pregnant client with type 1 diabetes mellitus about her understanding regarding changing insulin needs during pregnancy. The nurse determines that further teaching is needed if the client makes which statement? 1. “I will need to increase my insulin dosage during the first 3 months of pregnancy.” 2. “My insulin dose will likely need to be increased during the second and third trimesters.” 3. “Episodes of hypoglycemia are more likely to occur during the first 3 months of pregnancy.” 4. “My insulin needs should return to prepregnant levels within 7 to 10 days after birth if I am bottle-feeding.” Rationale: Insulin needs decrease in the first trimester of pregnancy because of increased insulin production by the pancreas and increased peripheral sensitivity to insulin. The statements in options 2, 3, and 4 are accurate and signify that the client understands control of her diabetes during pregnancy. 212. A pregnant client reports to a health care clinic, complaining of loss of appetite, weight loss, and fatigue. After assessment of the client, tuberculosis is suspected. A sputum culture is obtained and identifies Mycobacterium tuberculosis. Which instruction should the nurse include in the client’s teaching plan? 1. Therapeutic abortion is required. 2. Isoniazid plus rifampin will be required for 9 months. 3. She will have to stay at home until treatment is completed. 4. Medication will not be started until after delivery of the fetus. Rationale: More than one medication may be used to prevent the growth of resistant organisms in a pregnant client with tuberculosis. Treatment must continue for a prolonged period. The preferred treatment for the pregnant client is isoniazid plus rifampin daily for 9 months. Ethambutol is added initially if medication resistance is suspected. Pyridoxine (vitamin B6) often is administered with isoniazid to prevent fetal neurotoxicity. The client does not need to stay at home during treatment, and therapeutic abortion is not required. 213. The nurse is providing instructions to a pregnant client with a history of cardiac disease regarding appropriate dietary measures. Which statement, if made by the client, indicates an understanding of the information provided by the nurse? 1. “I should increase my sodium intake during pregnancy.” 2. “I should lower my blood volume by limiting my fluids.” 3. “I should maintain a low-calorie diet to prevent any weight gain.” 4. “I should drink adequate fluids and increase my intake of high-fiber foods.” Rationale: Constipation can cause the client to use the Valsalva maneuver. The Valsalva maneuver should be avoided in clients with cardiac disease because it can cause blood to rush to the heart and overload the cardiac system. Constipation can be prevented by the addition of fluids and a high-fiber diet. A low-calorie diet is not recommended during pregnancy and could be harmful to the fetus. Sodium should be restricted as prescribed by the primary health care provider, because excess sodium would cause an overload to the circulating blood volume and contribute to cardiac complications. Diets low in fluid can cause a decrease in blood volume, which could deprive the fetus of nutrients. 214. The clinic nurse is performing a psychosocial assessment of a client who has been told that she is pregnant. Which assessment findings indicate to the nurse that the client is at risk for contracting human immunodeficiency virus (HIV)? Select all that apply. 1. The client has a history of intravenous drug use. 2. The client has a significant other who is heterosexual. 3. The client has a history of sexually transmitted infections. 4. The client has had one sexual partner for the past 10 years. 5. The client has a previous history of gestational diabetes mellitus. 215. The nurse in a maternity unit is providing emotional support to a client and her significant other who are preparing to be discharged from the hospital after the birth of a dead fetus. Which statement made by the client indicates a component of the normal grieving process? 1. “We want to attend a support group.” 2. “We never want to try to have a baby again.” 3. “We are going to try to adopt a child immediately.” 4. “We are okay, and we are going to try to have another baby immediately.” 216. The nurse evaluates the ability of a hepatitis B–positive mother to provide safe bottle- feeding to her newborn during postpartum hospitalization. Which maternal action best exemplifies the mother’s knowledge of potential disease transmission to the newborn? 1. The mother requests that the window be closed before feeding. 2. The mother holds the newborn properly during feeding and burping. 3. The mother tests the temperature of the formula before initiating feeding. 4. The mother washes and dries her hands before and after self-care of the perineum and asks for a pair of gloves before feeding. Rationale: Hepatitis B virus is highly contagious and is transmitted by direct contact with blood and body fluids of infected persons. The rationale for identifying childbearing clients with this disease is to provide adequate protection of the fetus and the newborn, to minimize transmission to other individuals, and to reduce maternal complications. The correct option provides the best evaluation of maternal understanding of disease transmission. Option 1 will not affect disease transmission since hepatitis B does not spread through airborne transmission. Options 2 and 3 are appropriate feeding techniques for bottle-feedi
