• Intubation

• Chest compressions

What is the recommended cardiac compression rate during adult resuscitation?

• 80-100/min

• 120-140/min

• 100-120/min

What is the most important determinant of survival in patients with ventricular fibrillation?

• Performing chest compressions

• Securing airway connections

• Administering medications

• Time from collapse to defibrillation

What is the primary cause of pulmonary edema?

• Increased permeability of the alveolar–capillary membrane

• Decreased alveolar pressure

• Decreased hydrostatic pressure

• Cardiogenic factors

When should early elective tracheal intubation be considered?

• When oxygen levels drop significantly

• When the patient is stable

• When there are signs of heat injury to the airway

How is acute kidney injury (AKI) diagnosed according to the Acute Kidney Injury Network criteria?

• Increase in serum creatinine of more than 50%

• Decrease in blood pressure

• Regular exercise and balanced diet

What causes relative hypovolemia in patients with sepsis?

• Systemic pooling of blood and transudation of fluid into tissues

• Increased blood volume

• Normal fluid distribution

How is mechanical (ventricular) capture confirmed during pacing?

• Increasing respiratory rate

• Decreasing heart rate
