🔍 Key Concepts

• Effects of electric shock on the heart and breathing • Difference between cardiac arrest vs. shock or fainting • Typical signs of no effective circulation and no effective respiration

💭 Think About

• Think about what cardiac arrest actually means for the heart’s pumping action and pulse — would the pulse usually be strong, weak, or absent? • Consider how electric current passing through the body can affect the breathing center — what typically happens to respiration? • Look at each symptom and ask: does this clearly match the expected condition of someone in true cardiac arrest, or is it more typical of a less severe condition?

✅ Before You Answer

• Be clear on the definition of cardiac arrest: is the heart effectively pumping blood? • For each option, ask: would this symptom be consistently present in cardiac arrest from electric shock, or might it be misleading? • Check whether combining all listed symptoms in "all of the above" logically fits with the clinical picture of cardiac arrest.
