Betamethasone and Dexamethasone Adverse Effects

ADVERSE REACTIONS: * May decrease the mother's resistance to infection. * Pulmonary edema secondary to Na+ & fluid retention can occur. * Elevated blood glucose levels can occur in a client with diabetes mellitus.

An opioid analgesic is administered to a client in labor. The nurse assigned to care for the client ensures that which medication is readily available if respiratory depression occurs? 1. Naloxone 2. Morphine Sulfate 3. Betamethasone 4. Hydromorphone hydrochloride

Ans: 1 Rationale: Opioid analgesics may be prescribed to relieve moderate to severe pain associated with labor. Opioid toxicity can occur and cause respiratory depression. Naloxone is an opioid antagonist, which reverses the effects of opioids and is given for respiratory depression. Morphine Sulfate and hydromorphone hydrochloride are opioid analgesics. Betamethasone is a corticosteroid administered to enhance fetal lung maturity.

The nurse asks a nursing student to describe the procedure for administering erythromycin ointment to the eyes of a newborn. Which student statement indicates that further teaching is needed? 1. "I will flush the eyes after instilling the ointment" 2. "I will clean the newborn's eyes before instilling ointment" 3. "I need to administer the eye ointment within 1 hours after delivery" 4. "I will instill the eye ointment into each of the newborn's conjunctival sacs."

Ans: 1 Rationale: eye prophylaxis protects the newborn against Neisseria gonorrhoeae and Chlamydia trachomatis. The eyes are not flushed after instillation of the medication because the flush would wash away the administered medication. Options 2,3 and 4 are correct statements.

The nurse is monitoring a client in preterm labor who is receiving intravenous magnesium sulfate. The nurse should monitor for which adverse effects of this medication? SATA 1. Flushing 2. Hypertension 3. Increased urine output 4. Depressed respirations 5. Extreme muscle weakness 6. Hyperactive deep tendon reflexes

Ans: 1,4,5 Rationale: Magnesium sulfate is a central nervous system depressant and relaxes smooth muscle, including the uterus, it is used to halt preterm labor contractions and is used for preeclamptic clients to prevent seizures. Adverse effects include flushing, depressed RR, depressed DTR, hypotension, extreme muscle weakness, decreased urine output, pulmonary edema, and elevated serum magnesium levels.

A client in preterm labor (31 weeks) who is dilated to 4 cm has been started on magnesium sulfate & contractions have stopped. If the client's labor can be inhibited for the next 48 hours, what medication does the nurse anticipate will be prescribed? 1. Nalbuphine 2. Betamethasone 3. Rh (D) immune globulin 4. Dinoprostone vaginal insert

Ans: 2 Rationale: Betamethasone, a glucocorticoid, is given to increase the production of surfactant to stimulate fetal lung maturation. It is administered to clients in preterm labor at 28 to 32 weeks of gestation if the labor can be inhibited for 48 hours. Nalbuphine is an opioid analgesic. Rh Immune globulin is given to Rh-negative clients to prevent sensitization. Dinoprostone vagina insert is a prostaglandin given to ripen and soften the cervix and to stimulate uterine contractions.

Methylergonovine is prescribed for a woman to treat postpartum hemorrhage. Before administration of methylergonovine, what is the priority nursing assessment. 1. Uterine tone 2. Blood pressure 3. Amount of lochia 4. Deep tendon reflexes

Ans: 2 Rationale: Methylergonovine, an ergot alkaloid, is used to prevent or control postpartum hemorrhage by contracting the uterus. Methylergonovine causes continuous uterine contractions and may elevate the blood pressure. A priority assessment before the administration of the medication is to check the blood pressure. The OB needs to be notified if hypertension is present. Although options 1,3, and 4 may be components of the postpartum assessment, blood pressure is related specifically to the administration of this medication.

The nurse is preparing to administer exogenous surfactant to a premature infant who has respiratory distress syndrome. The nurse prepares to administer the medication by which route? 1. Intradermal 2. Intratracheal 3. Subcutaneous 4. Intramuscular

Ans: 2 Rationale: Respiratory distress syndrome is a serious lung disorder caused by immaturity and the inability to produce surfactant, resulting in hypoxia and acidosis. It is common in premature infants and may be due to lung immaturity as a result of surfactant deficiency. The mainstay of treatment is the administration of exogenous surfactant, which is administered by the intratracheal route. Options 1,3, and 4 are not routes of administration for this medication

A pregnant client is receiving magnesium sulfate for the management of preeclampsia. The nurse determines that the client is experiencing toxicity from the medication if which findings are noted on assessment? SATA 1. Proteinuria of 3+ 2. Respirations of 10 breaths/min 3. Presence of DTR 4. Urine output of 20 ml in 1 hr 5. Serum magnesium of 4 mEq/L (2mmol/L)

Ans: 2, 4 Rationale: Magnesium toxicity can occur from magnesium sulfate therapy. Signs of magnesium sulfate toxicity relate to the central nervous system depressant effects of the medication and include respiratory depression, loss of DTR, and a sudden decline in FHR and maternal HR and BP. RR lower than 12 Breaths/min is a sign of toxicity. Urine output should be at least 25-30 mL/hr. Proteinuria of 3+ is an expected finding in a patient with preeclampsia. Presence of DTR is a normal and expected finding. Therapeutic serum magnesium levels are 4-7.5 mEq/L (2-3.75 mmol/L)

The Nurse is monitoring a client who is receiving oxytocin to induce labor. Which assessment findings should cause the nurse to immediately discontinue the oxytocin infusion? SATA 1. Fatigue 2. Drowsiness 3. Uterine Hyperstimulation 4. Late Decelerations of the FHR 5. Early Decelerations of the FHR

Ans: 3, 4 Rationale: Oxytocin stimulates uterine contractions and is a pharmacological method to induce labor. Late decelerations, a nonreassuring FHR pattern, is an ominous sign indicating fetal distress. Oxytocin infusion must be stopped with any signs of uterine hyperstimulation, late decelerations, or other adverse effects occur. Some obstetricians prescribe the administration of oxytocin in 10 min pulsed infusions rather than as a continuous infusion. This pulsed method, which is more like endogenous secretion of oxytocin, is reported to be effective for labor induction and requires significantly less oxytocin use. Drowsiness and fatigue may be caused by the labor experience. Early decelerations of the FHR are a reassuring sign and do not indicate fetal distress.

Methylergonovine is prescribed for a client with postpartum hemorrhage. Before administering the medication, the nurse should contact the obstetrician who prescribed the medication if which condition is documented in the client's medical history? 1. Hypotension 2. Hypothyroidism 3. Diabetes mellitus 4. Peripheral vascular disease

Ans: 4 Rationale: Methylergonovine is an ergot alkaloid used to treat PPH. Ergot alkaloids are contraindicated in clients with significant cardiovascular disease, peripheral vascular disease, hypertension, preeclampsia, or eclampsia. These conditions are worsened by the vasoconstrictive effects of the ergot alkaloids. Options 1,2, and 3 are not contraindications related to the use of ergot alkaloids.

Rh (D) immune globulin is prescribed for a client after delivery, and the nurse provides information to the client about the purpose of the mediation. The nurse determines that the woman understands the purpose if the woman states that it will protect her next baby from which condition? 1. Having Rh-positive blood 2. Developing a rubella infection 3. Developing physiological jaundice 4. Being affected by Rh incompatibility

Ans: 4 Rationale: Rh incompatibility can occur when an Rh-negative mother becomes sensitized to the Rh antigen. Sensitization may develop when an Rh-negative woman becomes pregnant with a fetus who is Rh positive. During pregnancy and at delivery, some of the fetus's Rh-positive blood can enter the maternal circulation, causing the mother's immune system to form antibodies against Rh-positive blood. Administration of Rh immune globulin prevents the mother from developing antibodies against Rh-positive blood by providing passive antibody protection against the Rh antigen.
