Eclampsia is defined as seizures in a patient with preeclampsia and requires magnesium sulfate as first-line therapy. A loading dose of 4–6 g IV infused over ~10–15 minutes, followed by an infusion (e.g., 1–2 g/hr), reduces seizure recurrence and improves maternal outcomes. Benzodiazepines (A, C) can terminate seizures but do not address the underlying pathophysiology; they are adjuncts if seizures persist during magnesium administration. Levetiracetam (D) is increasingly used for status epilepticus but is not first-line for eclampsia. Monitor for magnesium toxicity (loss of deep tendon reflexes, respiratory depression); have calcium gluconate available as an antidote. Manage airway with left uterine displacement to reduce aortocaval compression, control blood pressure with labetalol or hydralazine per protocol, and prioritize rapid transfer to definitive obstetric care. Fetal assessment should occur at the receiving facility; maternal stabilization remains paramount.

In suspected intracranial hypertension, routine aggressive hyperventilation (EtCO₂ 25–30) risks cerebral vasoconstriction and ischemia and is reserved for brief rescue therapy in impending herniation. The preferred strategy is normocapnia (EtCO₂ ~35–40) while optimizing sedation/analgesia to reduce coughing, ventilator dysynchrony, and spikes in ICP. Option B addresses both ventilation and patient-ventilator interaction. Maintaining very high EtCO₂ (C) increases cerebral blood volume and ICP. Option D mixes moderate hypocapnia with high PEEP, which can increase intrathoracic pressure and reduce cerebral venous return; any osmotherapy (e.g., mannitol or hypertonic saline) should be coordinated with receiving team parameters and hemodynamics. Ensure head-of-bed elevation, neutral neck position, adequate MAP (CPP = MAP − ICP), and avoidance of hypoxia and hypotension.

Second-generation SGAs (i-gel, LMA Supreme) seal at higher pressures and include a gastric drain to vent insufflated air, improving ventilation and reducing aspiration risk—ideal in bloody fields where visualization is poor. Forcing pressure (A) worsens insufflation. Cricoid (C) can impair placement and lacks proven benefit. Blind nasal intubation (D) is low-success and traumatic. After exchanging, confirm with waveform capnography, assess chest rise, and consider fiberoptic intubation through the SGA or plan for surgical airway if ventilation remains inadequate. Secure the device meticulously and continue aggressive suctioning; reassess after any patient movement.

Low CVP with signs of poor perfusion and ultrasound evidence of low preload point to hypovolemia. Initial resuscitation with a 250–500 mL balanced crystalloid bolus (or blood if hemorrhage suspected) is appropriate, followed by reassessment of MAP, lactate, capillary refill, and ultrasound IVC dynamics. Vasodilators (A) will worsen hypotension. High-dose pressors (C) before volume can further compromise tissue perfusion and are generally reserved for distributive states or when fluids are contraindicated. Diuretics (D) are inappropriate. CCP-C practice emphasizes dynamic assessment—passive leg raise when feasible, stroke-volume surrogates (PPV in the right context), and clinical endpoints. Avoid over-resuscitation; re-evaluate lung ultrasound for B-lines indicating fluid sensitivity and trend perfusion markers to guide subsequent fluid/pressor decisions.

Prone positioning improves V/Q matching, alveolar recruitment, and survival in moderate–severe ARDS when safely executed for adequate durations. With a trained transport team, maintaining a patient already prone or carefully proning can be feasible, provided the ETT and lines are secured and pressure points padded. Universal prolonged recruitment maneuvers (A) risk hypotension and barotrauma and should be individualized. Increasing VT (C) violates lung-protective strategy. Reducing PEEP (D) risks derecruitment. During transport, ensure redundant tube security, consider neuromuscular blockade for synchrony, and monitor closely for hemodynamic instability during turns. Communicate with the receiving ICU to continue prone cycles and adjuncts (e.g., inhaled vasodilators) when indicated.
