The nurse knows that she is observing which aspect of the uterine contraction: a. frequency b. duration c. intensity d. resting tone or interval - Answer- c. intensity The nurse who is monitoring EFM realizes that suddenly there is no tracking of the FHR. What is the nurse's priority action? a. Immeadietely notify the physician. b. Check placement of the ultrasound transducer and ensure correct placement for optimum recording of fetal heart rate to see if the baby changed positions. c. Administer 8-10 L/min of oxygen to the mom and turn on her left side because the fetus is compromised. - Answer- b. Check placement of the ultrasound transducer and ensure correct placement for optimum recording of fetal heart rate to see if the baby changed positions. A nurse is explaining to her 31 year old patient that she will be using external fetal monitoring devices to keep track of the baby's FHR in relation to her uterine contractions. Which of the following are external fetal monitoring devices? (select all that apply) a. ultrasound transducer b. intrauterine pressure catheter c. tocotransducer d. spiral electrode - Answer- a. ultrasound transducer c. tocotransducer The nurse is using the ultrasound transducer during the EFM of her 35 year old patient. The patient asks her what the transducer is used for. What is the nurse's most appropriate response? a. "The ultrasound transducer uses high frequency sound waves to convert the Fetal EKG obtained from the presenting part, which is your baby's head." b. "The ultrasound transducer uses high frequency sound waves to detect the flow of blood through a vessel, which can be identified as your baby's heart rate." c. "The ultrasound transducer uses high frequency sound waves to measure your uterine contractions transabdominally." - Answer- b. "The ultrasound transducer uses high frequency sound waves to detect the flow of blood through a vessel, which can be identified as your baby's heart rate."
