HESI OB MATERNITY VERSION 1 AND 2 EXIT EXAM WITH VERIFIED SOLUTIONS AND RATIONALE/A+ GRADE

1. A 38-week primigravida who works as a secretary and sits at a computer for 8 hours each day tells the nurse that her feet have begun to swell. Which instruction wouldbe most effective in preventing pooling of blood in the lower extremities? Move about every hour Pooling of blood in the lower extremities results from the enlarged uterus exerting pressure on the pelvic veins. Moving about every hour will straighten out the pelvic veins and increase venous return. 2. A 26-year-old, gravida 2, para 1 client is admitted to the hospital at 28-weeks gestationin preterm labor. She is given 3 doses of terbutaline sulfate (Brethine) 0.25 mg subcutaneously to stop her labor contractions. The nurse plans to monitor for which primary side effect of terbutaline sulfate? Tachycardia and a feeling of nervousness Terbutaline sulfate (Brethine), a beta-sympathomimetic drug,stimulates beta-adrenergic receptors in the uterine muscle to stop contractions. The beta-adrenergic agonist properties of the drug may cause tachycardia, increased cardiac output, restlessness, headache, and a feeling of "nervousness". 3. When do the anterior and posterior fontanels close? anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month. 4. When assessing a client who is at 12-weeks gestation, the nurse recommends thatshe and her husband consider attending childbirth preparation classes. When is thebest time for the couple to attend these classes? 30 weeks gestation at 30 weeks gestation is closest (of the options) to the time parents would be ready for such classes. Learning is facilitated by an interested pupil! The couple is most interested in childbirth toward the end of the pregnancy when they are psychologically ready for the termination of the pregnancy, and the birth of their childis an immediate concern. 5. The nurse should encourage the laboring client to begin pushing when...the cervix is completely dilated. Pushing begins with the second stage of labor, i.e., when the cervix is completely dilatedat 10 cm (C). If pushing begins before the cervix is completely dilated the cervix 1 can become edematous and may never completely dilate, necessitating an operativedelivery. Many primigravida’s begin active labor 100%and theneffacedproceed todilate. 6. The nurse instructs a laboring client to use accelerated-blow breathing. The client begins to complain of tingling fingers and dizziness. What action should the nurse take? Have the client breathe into her cupped hands Tingling fingers and dizziness are signs of hyperventilation (blowing off too much carbon dioxide). Hyperventilation is treated by retaining carbon dioxide. This can befacilitated by breathing into a paper bag or cupped hands. 7. Twenty-four hours after admission to the newborn nursery, a full-term male infant develops localized edema on the right side of his head. The nurse knows that, in the newborn, an accumulation of blood between the periosteum and skull which does not cross the suture line is a newborn variation known as... a cephalohematoma, caused by forceps trauma and may last up to 8 weeks. Cephalohematoma, a slight abnormal variation of the newborn, usually arises within thefirst 24 hours after delivery. Trauma from delivery causes capillary bleeding between the periosteum and the skull. 8. When does the head return to its normal shape? 7-10 days 9. What did Nurse theorist Reva Rubin describe? The initial postpartum period as the "taking-in phase," which is characterized by maternal reliance on others to satisfy the needs for comfort, rest, nourishment, andcloseness to families and the newborn. 10. A couple, concerned because the woman has not been able to conceive, is referred toa healthcare provider for a fertility workup and a hysterosalpingography is scheduled. Which post procedure complaint indicates that the fallopian tubes are patent? Shoulder pain If the tubes are patent (open), pain is referred to the shoulder from a sub diaphragmatic collection of peritoneal dye/gas. 11. Which nursing intervention is most helpful in relieving postpartum uterine contractions or "afterpains?" Lying prone with a pillow on the abdomen 2 3 Lying prone keeps the fundus contracted and is especially useful with multiparas,who commonly experience afterpains due to lack of uterine tone. 12. Which maternal behavior is the nurse most likely to see when a new motherreceives her infant for the first time? Her arms and hands receive the infant and she then traces the infant's profile withher fingertips. Attachment/bonding theory indicates that most mothers will demonstrate behaviors described in during the first visit with the newborn, which may be at delivery or later. 13. A client at 32-weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved? A decreased in respiratory rate from 24 to 16 Magnesium sulfate, a CNS depressant, helps prevent seizures. A decreased respiratory rate indicates that the drug is effective. (Respiratory rate below 12 indicatestoxic effects.) 14. Urinary output must be monitored when administering magnesium sulfate and should be at least 30 ml per hour. (The therapeutic level of magnesium sulfate for a PIH clientis 4.8 to 9.6 mg/dl.) What is the therapeutic level of magnesium sulfate? The therapeutic level of magnesium sulfate for a PIH client is 4.8 to 9.6mg/dl. What does it help prevent? helps prevent seizures What indicates toxic levels? 3 Respiratory rate below 12 indicates toxic effects. Urine output of less than 100 ml/4 hours Absent DTR
