1 - Drinking orange juice before the test is appropriate. Show pg 238/239 - Vibroacoustic stimulation is often used to stimulate fetal activity if the initial NST result is nonreactive and thus hopefully shortens the time required to complete the test (Greenberg, Druzin, and Gabbe, 2012). A nonreactive test requires further evaluation. The testing period is often extended, usually for an additional 20 minutes, with the expectation that the fetal sleep state will change and the test will become reactive. Care providers sometimes suggest that the woman drink orange juice or be given glucose to increase her blood sugar level and thereby stimulate fetal movements. Although this practice is common, there is no evidence that it increases fetal activity (Greenberg, Druzin, and Gabbe, 2012). A needle biopsy is not part of a NST. The FHR is recorded with a Doppler transducer, and a tocodynamometer is applied to detect uterine contractions or fetal movements. The tracing is observed for signs of fetal activity and a concurrent acceleration of FHR. 1 - Remain still throughout the test. pg 234 - Magnetic resonance imaging (MRI) is a noninvasive radiologic technique used for obstetric and gynecologic diagnosis. Similar to computed tomography (CT), MRI provides excellent pictures of soft tissue. Unlike CT, ionizing radiation is not used. Therefore vascular structures within the body can be visualized and evaluated without injecting an iodinated contrast medium, thus eliminating any known biologic risk. Similar to sonography, MRI is noninvasive and can provide images in multiple planes, but no interference occurs from skeletal, fatty, or gas-filled structures, and imaging of deep pelvic structures does not require a full bladder. The woman is placed on a table in the supine position and moved into the bore of the main magnet, which is similar in appearance to a CT scanner. Depending on the reason for the study, the procedure may take from 20 to 60 minutes, during which time the woman must be perfectly still except for short respites. Which test does the nurse recommend for the patient to help assess fetal genetic abnormalities?Amniocentesis is a prenatal procedure that your doctor may recommend you have during pregnancy. The test checks for fetal abnormalities (birth defects) such as Down syndrome, cystic fibrosis or spina bifida. In most cases, the results are normal. Amniocentesis is performed between 16 and 20 weeks into the pregnancy.
What is level 3 ultrasound in pregnancy?LEVEL-3. Colour Doppler Scan (About 28-32 wks): Doppler Ultrasound gives doctors a visual or audible representation of blood movement through veins, arteries and blood vessels with sound waves.
What parameter does the nurse check in the amniocentesis quizlet?What parameter does the nurse check in the amniocentesis report of a pregnant patient to assess fetal lung growth? The L/S ratio indicates fetal lung maturity. AFP is assessed to check for the presence of neural defects.
Why is assessment of risk factors in a pregnant woman important?Risk assessment in pregnancy helps to predict which women are most likely to experience adverse health events and enables providers to administer risk-appropriate perinatal care.
