What is an ultrasound? correct answers It's a procedure where you can visualize internal organs
and tissues by producing a real time three dimensional image of the developing fetus and
maternal structures (fetal heart and pelvic anatomy) ?
what are the types of ultrasound that can be done? correct answers -external abdominal
-transvaginal
-doppler
what's an external abdominal ultrasound? correct answers a safe noninvasive painless procedure
where an ultrasound transducer is moved over a client's abdomen to obtain an image
when is an external abdominal ultrasound effective? correct answers after the first trimester
when the uterus is bigger.
what's an internal transvaginal ultrasound? correct answers an invasive procedure in which a
probe is inserted vaginally to alllow for more accurate evaluation.
what's the advantage of a internal transvaginal ultrasound? correct answers You do not need a

what is a doppler ultrasound? correct answers a noninvasive external ultrasound method to study
the maternal fetal blood flow by measuring the velocity at which RBCs travel in the uterine and
fetal vessels using a handheld ultrasound device that reflects sound waves from a moving target.
what is a dppler ultrasound blood flow analysis useful for? correct answers useful to determine
fetal intrauterine growth restriction and poor placental perfusion and as adjunct in pregnancies at
risk because of hypertension, diabetes, multiple fetusses, or prterm labor
what are some indications for ultrasounds during pregnancy? correct answers -confirm
pregnancy
-confirm gestational age
-identify multifetal pregnancy
-site of fetal implantation
-assessing fetal growth or development
-assessing maternal structures
-confirming viability or death
-ruling out or verifying fetal abnormalities
-locating site of placental attachment
-determining amniotic fluid volume
-fetal movement observation (fetal heartbeat, breathing and activity)
-placental grading (evaluating fetal maturation)
