ÀNTHROPOLO

A nurse is reviewing the medical record of a client who has preeclampsia prior to administering labetalol. For which of the following findings should the nurse withhold the medication? a. Uric acid 7.5 mg/dL: The nurse should identify that a uric acid level of 7.5 mg/dL is above the expected reference range of 2.7 to 7.3 mg/dL for a client who is pregnant. Elevated uric acid is a manifestation of preeclampsia and is caused by decreased renal perfusion. However, an elevated uric acid level is not a contraindication for the administration of labetalol, an antihypertensive medication. b. Heart rate 54/min: The nurse should identify that a heart rate of 54/min is below the expected reference range of 60 to 100/min. During pregnancy, the heart rate increases 10 to 15/min due to increased blood volume and increased tissue demands for oxygen. Bradycardia is a contraindication for the administration of labetalol, an antihypertensive medication. Therefore, the nurse should withhold the medication and notify the provider. c. FHR 112/min: The nurse should identify that an FHR of 112/min is within the expected reference range of 110 to 160/min. Preeclampsia can cause a decrease in placental perfusion, leading to fetal hypoxia. The nurse should closely monitor the FHR for manifestations of fetal distress. However, the nurse should not withhold labetalol, an antihypertensive medication, for this finding. d. BUN 23 mg/dL: The nurse should identify that a BUN of 23 mg/dL is above the expected reference range of 10 to 20 mg/dL for a client who is pregnant. An elevated BUN is a manifestation of preeclampsia and is caused by decreased renal perfusion. However, an elevated BUN is not a contraindication for the administration of labetalol, an antihyp
