Critical care 1
Most common complication of smoke inhalation injury
Pneumonia
Treatment for cyanide poisoning
Hydroxocobalamin
Preferred treatment for benzodiazepine overdose
Supportive care (not flumazenil)
Type of IV catheter with highest flow rate
Peripheral wide-bore catheter
Most common cause of cardiogenic shock
Myocardial infarction
Diagnostic test for carbon monoxide exposure
Arterial blood gases, including co-oximetry
Only indications for benzodiazepines in delirium treatment
Alcohol withdrawal, seizures
Assessment test before liberation from mechanical ventilation
Spontaneous breathing trial
Measures in ventilatory assessment of neuromuscular weakness
Maximum inspiratory and expiratory pressures, positional changes in FVC
Common causes of systemic toxicity in smoke inhalation
Carbon monoxide, cyanide
Strategies to decrease delirium during mechanical ventilation
Daily interruptions of sedation and analgesia; protocolized light sedation; melatonin
Preferred agents for continuous sedation during mechanical ventilation
Propofol, dexmedetomidine
Common bacterial causes of pneumonia after smoke inhalation
Staphylococcus and Pseudomonas species
Carboxyhemoglobin level indication for hyperbaric therapy
≥25%
Basic strategies to minimize ICU-acquired weakness
Early mobilization, avoidance of early parenteral nutrition, glucose control
Ventilatory treatment of acute hypercapnic respiratory failure from OHS
BPAP
Treatment for PE with hemodynamic collapse
Thrombolytic therapy
Role of procalcitonin in initiation of antibiotics
None
Treatment for cardiac arrest with hypothermia
Prolonged CPR and active rewarming
Timing of antibiotic therapy in suspected sepsis
Within first hour
Physiology of hypoxemic respiratory failure not improving with oxygen
V/Q mismatch (specifically low V/Q, or shunt)
Diagnosis suggested by hyperthermia, hyperreflexia, dysautonomia, mental status changes
Serotonin syndrome
Drug treatment for methanol and ethylene glycol poisoning
Fomepizole
Diagnosis suggested by CNS depression, increased anion gap metabolic acidosis, increased osmolal gap
Ethylene glycol or methanol ingestion
Treatment for shock refractory to fluids and vasopressors
Hydrocortisone
