AWHONN ADVANCED FETAL MONITORING EXAM LATEST ACTUAL EXAM 2025 WITH 130 QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) ALREADY GRADED A+ What differs in fetal CO from adult CO? - ANSWER-The stoke volume does not fluctuate What happens when the fetal heart decreases (in regards to CO)? - ANSWER-The CO decreases which leads to hypoxia and acidemia What is the fetal Hct? - ANSWER-51-56% What are 3 fetal physiologic adaptations from the mother? - ANSWER-Increased Hct 2 | P a g e Fetal Hbg has a higher affinity for O2 Fetal HR and CO is increased which results in rapid circulation of O2 blood What is the fetal response to acute hypoxia - ANSWER-Increased blood flow to vital organs (heart, brain, adrenals) Decreased blood flow to spleen, kidneys, and limbs FHR slows and myocardium decreases O2 consumption The metabolism that takes place in the absence of oxygen; the principle product is lactic acid. - ANSWER-anaerobic metabolism Explain the oxygenation depletion cascade - ANSWER-Aerobic metabolism with O2 then there's hypoxemia (decrease in O2) which leads to tissue hypoxia. The body is forced to resort to anaerobic metabolism which leads to a buildup of lactic acid in the 3 | P a g e blood. This then causes metabolic acidosis (causes cellular death). How one does it take for significant acidemia to take place? - ANSWER-60-90 minutes What is marked variability mediated by? - ANSWER-Adrenergic activity What are things that can cause decreased variability? - ANSWER-Opioids, magnesium, and tobacco (medications or drugs) Fetal sleep cycles Fetal acidemia- there will be no accels here 4 | P a g e What accelerations do gestations less than 32 weeks need? - ANSWER-10x10 Describe the reasoning for early decels - ANSWER-Fetal head compression leads to altered cerebral blood flow which produces a vagabond reflex and cardiac slowing Describe the physiology of a late decel - ANSWER-Uteroplacental insufficiency results in decreased maternal/fetal O2 transfer What do late decels with moderate variability mean and indicate? - ANSWER-It's neurogenic Exclude clinically significant acidemia Provide interventions to increase perfusion
