   1. A.Bronchospasm
   2. B.Malicious hypothermia
   3. C.Massive pulmonary embolism or cardiac arrest
   4. D.Esophageal intubation

3. Question 3Q-7358E1

   Which of the following pulse oximetry phenomena is based on the principle that the pulsatile component (AC) of light absorption corresponds to arterial blood, while the non-pulsatile component (DC) corresponds to tissue, skin, and venous blood?

   1. A.Beer-Lambert Law
   2. B.Fourier transformation
   3. C.Plethysmography
   4. D.See-saw effect

4. Question 4Q-69E5AD

   A patient in the ICU suffers ventricular fibrillation cardiac arrest. After high-quality CPR and the first delivery of a biphasic defibrillation shock, what is the immediate next step in management?

   1. A.Check carotid pulse for return of spontaneous circulation
   2. B.Resume chest compressions immediately for 2 minutes
   3. C.Administer Amiodarone 300 mg IV

5. Question 5Q-52F636

   Which invasive blood pressure monitoring transducer artifact occurs when the natural frequency of the monitoring system is close to the frequency of the pulse wave, resulting in a falsely elevated systolic pressure reading?

   1. A.Underdamping
   2. B.Overdamping
