ACLS Q uiz All Answers Correct 1. **A 59 -year -old patient is experiencing difficulty breathing. Physical exam reveals nasal flaring , intercostal retraction, and use of accessory muscles. The respiratory rate is 28 breaths per minute, oxygen saturation is 92%, and PTCO2 is 36 mmHg. How would you categorize this patient's condition?** ✔️ Respiratory distress. 2. **A 75 -year -old pati ent is having difficulty breathing with increased respiratory effort and a history of emphysema. The patient is drowsy, auscultation reveals bilateral wheezing, though lung sounds are difficult to appreciate. The respiratory rate is 38/min, oxygen saturati on is 85%, and PETCO2 is 49 mmHg. How would you categorize this patient's condition?** ✔️ Respiratory failure. 3. **A patient with suspected opioid poisoning is not breathing normally but has a pulse. What is your next step?** ✔️ Provide rescue brea thing and administer naloxone. 4. **A patient with a ventricular assist device (VAD) is not breathing, shows signs of inadequate perfusion, and is unconscious. You determine the VAD is functioning. After endotracheal intubation, the patient has a PETCO2 o f 12 mmHg. What is your next action?** ✔️ Perform external chest compressions. 5. **A patient without dyspnea shows signs of acute coronary syndrome. There are no obvious signs of heart failure. You assess a noninvasively monitored oxyhemoglobin satura tion. What is the oxygen saturation threshold below which supplemental oxygen would be required?** ✔️ 90%. 6. **Among others, which factor has been associated with improved survival in patients with cardiac arrest?** ✔️ Immediate high -quality CPR. 7. **An 18 -year -old patient is reporting difficulty breathing and is displaying increased respiratory effort. Auscultation reveals bilateral wheezing; the respiratory rate is 28 breaths per minute. Oxygen saturation is 91% and PETCO2 is 44 mmHg. How would you categorize this patient's condition?** ✔️ Respiratory distress. 8. **Coronary perfusion pressure (CPP) equals aortic ---- pressure minus right atrial diastolic pressure.** ✔️ Diastolic. 9. **Depending on training and individual circumstances, h ow can rescuers administer naloxone?** ✔️ Intranasally, intravenously, intramuscularly. Durin g CPR, chest compression fraction (CCF) should be at least --- and ideally greater than 80%. ✔️60% During the management of a patient in cardiac arrest, you have initiated CPR, attached the manual defibrillator, delivered the first shock, and immediately resumed high quality CPR, beginning with chest compressions. What is your next intervention? ✔️Establish IV or IO access During the post -cardiac arrest care period, the 12 -lead EKG reveals ST -segment elevation myocardial infraction. Which step has the hig hest priority? ✔️Coronary angiography During the post -cardiac arrest care phase, your team has optimized the patient's oxygenation, ventilation, and hemodynamic status. The patient's 12 -lead EKG identifies St -segment elevation MI, and the patient is being prepped for transport to the cath lab to undergo coronary reperfusion therapy. Why is it important to assess the patient's ability to follow commands? ✔️To determine the need for targeted temperature management EKG: during the EKG you note the presence of more P waves than QRS complexes. You also note all PR intervals have a uniform length but random QRS complexes are dropped. What type of atrioventricular block is most likely present? ✔️2nd degree AV block - Type II EKG: you note presence of more P waves than QRS complexes. You also note the absence of a relationship between P waves and QRS complexes. What type of atrioventricular block is most likely present? ✔️3rd degree Av block Evidence suggests that there is a higher likelihood of good to excellent functional outcome when alteplase is gi ven to adults with an acute ischemic stroke within what time frame? ✔️3 hours Generally speaking, electrical cardioversion is not recommended as the initial therapy for patients unless the heart rate is above ✔️150/min How do interruptions in chest compr essions negatively impact survival after cardiac arrest? ✔️Decrease coronary perfusion pressure How long should the second rescuer squeeze the bag mask device when providing 2 -rescuer ventilation? ✔️1 second How long should you wait to determine the neur ologic prognosis of a patient treated with targeted temperature management after the patient returns to normothermia? ✔️72 hours How much of a safety margin (energy above the dose at which consistent capture is observed) should you allow when the transcut aneous pacemaker? ✔️2mA How much tidal volume must provide with a bag -mask device to produce visible chest rise for an adult patient in respiratory arrest? ✔️6 to 7 mL/kg How quickly does the chance of survival describe for every minute of defibrillation delay in patients with ventricular fibrillation (VF) who do not receive bystander CPR? ✔️7-10% How quickly should resuscitation Team leaders consider perimortem cesarean delivery after beginning resuscitative efforts it returns of spontaneous circulation has not been achieved? ✔️5 minutes How will the current generation of continuous -flow left ventricular assist devices complicate the BLS assessment? ✔️The devices will not produce a pulse
