It is your mom's birthday today. you and your dad are out doing some last minute shopping for the party you are throwing her tonight. the two of you decide to pick her up a bottle of perfume from the mall. the sales clerk is "swamped". she has no and several people waiting in line to purchase items. you can tell she is getting very frustrated as she is rushing around trying to all the customers. you notice that she is sweating and looks very flush. a couple of minutes later she turns extremely pale and falls to the floor unconscious. a customer rushes behind the counter to her. she says “she must be having a heart attack - does anyone know cpr". what steps should you take? (hint: you need to know what she needs, don’t just take the person yelling cpr as fact! )
