Question

14. Differentiate between variable, early and late decelerations. Explairn their cause, patient teaching and nursing considerations. 15. What are accelerations? Are these a concern for the patient?

Answer 1

14)The variable deceleration refers to the downfall of the FHR (feral heart rate) and then recovery phase takes place.It is usually caused by umbilical cord compression. The patient can be educated to change position of lying down,The nurse has to stop pitocin and contact doctor immediately and meanwhile administer oxygen.They resemble typically V snapped waves

Late deceleration

This is a decrease in fetal heart rate below the fetal base line heart rate.It is caused by head compression ,uteroplacental insufficiency, placental exchange. Turn mother to her side,Maintain IV access,stop pitocin,monitor fetal heart rate, administration of oxygen

Early deceleration

Here there is a gradual decrease in FHR and then returning to baseline fetal heart rate.It occurs during contractions and later settles down

15) Acceleration in Labour is a sudden increase in the fetal heart rate.It is a prognostic indicator of Labour.This is a normal process occurring every 30 seconds and gradually seconds decrease,when it is too rapid it may lead to precipitate Labour leading yo a concern
