NURSING 265 Lecture Notes - Lecture 11: Ectopic Pregnancy, Fetus, Nonstress Test
Document Summary
Consists of high-frequency sound waves used to visualize internal organs and tissues. An invasive procedure in which a probe is inserted vaginally to allow for a more accurate evaluation. Useful in clients who are obese and those in the first trimester to detect an ectopic pregnancy, identify abnormalities, and to establish gestational age. At third trimester for preterm labor evaluation for cervical measurement. 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. Uses a real-time ultrasound to visualize physical and physiological characteristics of the fetus and observe for fetal biophysical responses to stimuli. Bpp 4 or lower is very bad. Bpp assesses fetal well-being by measuring the following five variables with a score of 2 for each normal finding, and 0 for each abnormal finding for each variable.
