Question: A patient with early sepsis develops tachycardia at 09:00. At which point in the compensatory sequence would you first expect tachypnea to appear? Need Assignment Help? Option A After tachycardia and early BP changes - once tissue hypoperfusion has produced metabolic acidosis sufficient to activate chemoreceptors Option B At the same time as urine output begins to fall - RAAS activation and chemoreceptor activation occur simultaneously Option C Simultaneously with the tachycardia - the SNS drives both responses at the same moment Option D Only after SpO2 begins to fall below 94% - tachypnea is a response to hypoxemia, not acidosis
