1. 1. What is the primary purpose of ventilation during CPR?

          

         

         

         

• A) To maintain adequate oxygenation and eliminate carbon dioxide

• B) To stimulate the respiratory centers of the brain

• C) To open the airway

• D) To increase heart rate and cardiac output

2. 2. How does a Venturi mask deliver a specific

    concentration of oxygen to a patient?

  

  

   

    

 

•   A) By using a low flow of oxygen to avoid causing aspiration

• B) By increasing the oxygen flow to more than 10 L/min

• C) By creating a high-velocity jet stream that pulls in room air

• D) By inflating a reservoir bag to ensure higher oxygen concentration

3. You are performing CPR on an unconscious patient and need to ensure their airway is open. Which of the following techniques would you use?

        

         

         

• A) Use an oropharyngeal airway to prevent airway obstruction

• B) Administer high-flow oxygen immediately

           

• C) Perform a jaw thrust maneuver to open airway

• D) Insert an endotracheal tube without checking the patient's airway

4. Why is bag-mask ventilation (BVM) not suitable for long-term ventilation in a cardiac arrest situation?

• a) It is difficult to properly secure the mask in place

• b) It often leads to gastric inflation and possible aspiration

• c) It cannot deliver enough oxygen during resuscitation

• d) It increases the risk of hypoxia in the patient

5. If a patient in cardiac arrest is intubated with an

    endotracheal tube (ETT), which of the following is 

    the most effective method to confirm the correct

    placement of the tube?

          

       

• A) Observe the patient's skin color only

• B) Visualize the chest rise during ventilation

• C) Use only auscultation of the epigastrium

• D) Administer medications to check if the patient responds
