An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: {Ans: Occlusion of the umbilical vein The etiology of variable decelerations is likely related to umbilical venous and arterial occlusion. Initially, with occlusion of the thin-walled umbilical vein, venous return to the fetal right atrium is reduced, producing a reflex tachycardia. This pattern often is observed as a shoulder on the FHR monitor strip immediately before the abrupt variable FHR deceleration Source: https://www.glowm.com/section-view/heading/Intrapartum%20Fetal%20Monitoring/item/202#}Which deceleration in the FHR is considered benign and does not require an intervention to correct? {Ans: Early deceleration}When assessing a FHR tracing, the first step is to {Ans: Estabilish the baseline rate}During a contraction, the tocodynamometer detects: {Ans: Pressure created by tensing of uterine muscles}If the umbilical vein is the only vessel occluded during cord compression {Ans: Deoxygenated blood cannot be removed from fetal circulation During umbilical cord compression, the vein on the umbilical cord becomes compressed leading to CO2 (carbon dioxide) to accumulate in your baby's blood, which produces respiratory acidosis.
