Choose the correct statement regarding end-tidal carbon dioxide (ETCO2) measurement during resuscitation.Question 51Answera.During CPR, survival is increased if ETCO2 is kept below 10 mmHg.b.There is a strong correlation between coronary perfusion pressure and ETCO2.c.Return of spontaneous circulation (ROSC) results in an immediate decrease in ETCO2.d.In a normal patient, ETCO2 is approximately 15-20 mmHg lower than PACO2.

What will CPR do to help a person in cardiac arrest?increase action potential in the hearttemporarily supply body with oxygen until help arrivesdecrease action potential

1. What are the vital characteristics of first-rate CPR?Starting chest compressions within 10 seconds of recognition of cardiac arrestMinimizing interruptionsPushing hard and fastAll of the above2. What should you do if the individual chest is wet when using an AED?Quickly wipe it dry before proceeding with AED use.Do not use an AED device.Proceed with AED use as usual.Rub isopropyl alcohol on the individual skin before proceeding with AED use.3. Why are breaths so important for children and infants in cardiac arrest?Because they often have respiratory failure that reduces the oxygen content in the blood before the onset of arrest.Because breaths help to dislodge foreign bodies.Because they have smaller lungs.None of the above4. In both children and infants, the compression to ventilation ratio for two-rescuer CPR is:15:230:130:215:15. When looking for a pulse on a child from one year to puberty, where should you check?Popliteal arteryCarotid or femoral arteryBrachial arteryTemporal artery

The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?No sweat, you're still learning!Arterial lactate level of 1.0 mEq/LCardiac output of 2.5 L/minMixed venous (SvO2 ) of 40%Cardiac index of 1.5 L/min/m2

Compressions only CPR is advised when you are:a. Unable to provide rescue breathsb. Concerned about the possibility of infectionc. Your concerns would result in no attempt at CPRd. All of the above
