650 mL (20 mL/kg of body weight)

which statement concerning the use of IV fluids in cardiac arrest is true?

IV fluid may be of benefit in cardiac arrest associated with hypovolemia

Which of these events signals a ROSC in an intimated cardiac arrest pt?

a sudden, persistent increase in ETCO2

Which of the following statements regarding chest compressions in CPR is accurate?

adequate chest compressions build up enough pressure within the cardiovascular system to allow perfusion

All of the following interfere with cardiac output during CPR EXCEPT:

allowing complete recoil of the chest wall during compressions

a return of spontaneous circulation in a pt in cardiac arrest is confirmed by all of the following EXCEPT:

an organized rhythm on the cardiac monitor

which of these would be the LEAST helpful as a benchmark for a community's resuscitation program?

average age of cardiac arrest pts in a community

baroreceptors that recognize hypotension caused by blood loss are located in:

carotid arteries

the phase of clotting in which fibrin is released normally takes 7-10 min. this is called:

coagulation phase

you are managing a cardiac arrest outside a shopping center, 4 minutes away from the hospital. bystander cpr was in progress upon your arrival, and the initial rhythm analysis indicated the need for a shock. after the shock and 2 minutes of cpr, the patient has a carotid pulse. which of these is the best plan for managing the patient?

ensure good airway management and ventilation, then transport

Which of the following statements regarding a patient in cardiac arrest from a suspected tension pneumothorax is true?

if paramedic assistance is unavailable, transport without delay

in obstructive shock, fluids can:

increase preload

a patient who regained spontaneous circulation after cpr and defibrillation has a bp of 84/50 mmHg. medical direction gives you an order to start an IV and infuse 1 liter normal saline to treat the hypotension. the order provides an example of:

integrated post-cardiac arrest care

how is the need for a change in practice in a resuscitation program indicated?

measuring benchmarks for program performance

You are transporting a pt who has been on antibiotics for a UTI. his wife called EMS because it was uncharacteristically confused. he responds to verbal stimuli, & his skin is very cool and moist. radial pulse was weak but regular at 124 bpm. RR: 24, BP: 92/64. when reassessing vitals, which of the following is necessary?

obtain a history of present illness

Effective CPR produces circulation that is about _____ the normal amount

one-fifth

After analyzing a cardiac arrest pt's heart rhythm, the AED tells you to deliver shock. after clearing the pt:

press the shock button, then perform CPR for 2 minutes

Which of the following contributes MOST to survival from cardiac arrest?

public access defibrillation programs & the public being trained in CPR

You have arrived to the scene of a "sick person" to find an elderly woman unresponsive in her bed. her husband said he could not wake her this morning. the woman does not appear to be breathing, & you confirm she is pulseless. which of the following should you do next?

quickly check for rigor mortis & dependent lividity

you and your partner have arrived at a scene where bystanders are performing CPR on an elderly woman who was found unresponsive in her home. which of the following should you do first?

quickly check the pulse as you direct bystanders to switch roles

which of these would be an appropriate quality indicator of a community's resuscitation program?

the % of witnessed cardiac arrests in which bystander CPR is started

Which of the following supports the emphasis on the need for early defibrillation in cardiac arrest?

the greater the interval between arrest & the start of resuscitation, the poorer the patient's chances of survival

Which of these is the best way to maintain the highest perfusion pressure possible during CPR?

use a "push hard and push fast" approach to chest compressions

you are caring for a pt found in cardiac arrest who had a ROSC following a single defibrillation. he is unresponsive and not breathing spontaneously. he has an spO2 of 95% with BVM ventilations, ETCO2 of 40 mmHg, pulse of 116 that's weak and occasionally irregular, and bp of 84 systolic. you should anticipate that you may need to do all of the following EXCEPT:

ventilate the pt aggressively
