When does the nurse refer the pregnant patient for ultrasonography to detect maternal abnormalities that could affect the fetus?

1 - Drinking orange juice before the test is appropriate.
2 - Vibroacoustic stimulation may be used during the test.
5 - Two sensors are placed on the abdomen to measure contractions and fetal heart tones.

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.
4 - Jewellery must be removed before 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.

When do you have ultrasounds during high

A high-risk ultrasound is generally performed between 20 to 30 weeks into the pregnancy and is reviewed by a Perinatologist who is equipped with better equipment than what is utilized during a standard ultrasound.

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.

When is level 3 ultrasound done?

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. The reflected sound can be used to diagnose restricted blood flow, blood clotsand fetal health.

What is the role of ultrasound in management of pregnancy?

Ultrasound imaging is useful in preventing maternal and perinatal mortality due to accurate dating of gestational age, especially when obtained in the first trimester. Ultrasound is also used for monitoring fetal growth and well being to enable early intervention when necessary.
