Shock and Advanced Cardiac Life Support MCQ ALS for Pacific Family Medicine pre-course test. This is an open book exam, and candidates may refer to the Youtube videos, ALS handbook, or other resources. However, candidates may not ask other candidates for their answers - this is cheating! OK Question Title * 1. Please enter your name in the text box ... OK Question Title * 2. Which of the following is the medical definition of shock? Acute circulatory failure causing inadequate end organ perfusion. Acute circulatory failure causing hypotension with systolic BP less than 80-90 correlating in the loss of the radial pulse. Acute circulatory failure with anaerobic metabolism in the tissues and elevated levels of serum lactate. Acute circulatory failure with hypotension, oliguria and elevated levels of serum lactate. OK Question Title * 3. Which one of the following conditions is NOT included in the classification of shock? Hypovolaemic shock due to haemorrhage or fluid loss. Electric shock due to high voltage electricity. Cardiogenic shock due to poor cardiac output caused by myocardial infarction or cardiac injury. Distributive shock due to sepsis, anaphylaxis or neurological injury. OK Question Title * 4. Which one of the following is a relatively late sign in hypovolaemic shock? Tachycardia Capillary refill prolonged >5 seconds Altered mental state Hypotension OK Question Title * 5. Which one or of the following conditions does NOT cause hypovolaemic shock? Gatroenteritis Burns Intra-cranial haemorrhage Fractured femur OK Question Title * 6. Which one or of the following actions is NOT used to control haemorrhage? Blood products. Tourniquet. Fluid bolus. Tranexamic acid. OK Question Title * 7. Which ONE answer below explains neurogenic shock? Head injury causing increased Vagus nerve activity producing bradycardia. Spinal cord injury above T6 interrupting sympathetic outflow leaving Vagus nerve action unopposed. Spinal cord injury interrupting sympathetic outflow between T1 and L2 causing vasodilation of arterioles and veins. All of the above. OK Question Title * 8. Which one of the following would NOT benefit a trauma patient with haemorrhagic shock? Metaraminol (Aramine). Traction splint (Thomas splint). Ketamine. Intraosseous access. OK Question Title * 9. Which one of the following is TRUE in the management of cardiac arrest? Advanced Life Support interventions are more effective than Basic Life Support interventions. Intravenous adrenaline achieves faster blood levels and has a faster clinical effect than intraosseous adrenaline. Endotracheal intubation should be performed early to then allow chest compressions to continue to be performed whilst ventilating the patient throughout CPR. Cardiac compressions and rescue breathing should be performed in children and drowning victims. OK DONE
