ACLS Final Exam ( Updated 2024 ) Complete Questions & Answers (Solved) 100% Correct 1. A patient with suspected acute coronary syndromes (ACS) is placed on a cardiac monitor. The patient is complaining of dyspnea and is given supple- mental oxygen.The provider determines that the oxygen is effective based onwhich SaO2 level? Answer: When a patient presents with potential ACS, the patientshouldhave oxygen administered to maintain an SaO2 of at least 94%. 2. A patient experiences cardiac arrest, and the resuscitation team initiates ventilations using a bag-valve-mask (BVM) resuscitator. The development of which condition during the provision of care would lead the team to suspectthat improper BVM technique is being used? Answer: Complications can occur with theuse of a BVM resuscitator due to improper technique. Delivering excessive volumeor ventilating too fast creates excessive pressure that can damage the airways, lungsand other organs. Excessive volume can lead to tension pneumothorax. 3. Assessment of a patient reveals an ETCO2 level of 55 mmHg and an arterialoxygen saturation (SaO2) level of 88%. The provider would interpret these findings as indicative of which condition? Answer: An SaO2 level of less than 90% (PaO2 of less than 50 mmHg) accompanied by ETCO2 values greater than 50 mmHg is indicative of respiratory failure. 4. A healthcare provider initiates ventilations to ensure adequate breathing and oxygenation. While ventilations are being performed, capnography is established to evaluate the adequacy of the ventilations.The healthcare providerdetermines that ventilations are adequate based on which end-tidal carbon dioxide (ETCO2) value? Answer: End-tidal carbon dioxide values in the range of 35 to 45mmHg confirm adequacy of ventilation. 5. A patient comes to the emergency department complaining of palpitationsand "some shortness of breath." Cardiac monitoring is initiated and reveals the following ECG rhythm strip.The provider interprets this strip as indicatingwhich arrhythmia? Answer: In atrial flutter, atrial contraction occurs atsuch a rapid rate thatdiscrete P waves separated by a flat baseline cannot be seen on the strip. Instead,the baseline continually rises and falls, producing the "flutter" waves.In leads II andIII, the flutter waves may be quite prominent, creating a "sawtooth" pattern.Becauseof the volume of atrial impulses, the AV node allows only some of the impulses to passthrough to the ventricles.In atrial flutter, a 2:1 ratio isthe most common (i.e., forevery two flutter waves, only one impulse passes through the AV node to generatea QRS complex). Ratios of 3:1 and 4:1 are also frequently seen. 6. A person suddenly collapses while sitting in the sunroom of a healthcare facility. A healthcare provider observes the event and hurries over to assessthe situation. The healthcare provider performs which assessment first? Answer: A systematic approach to assessment is necessary. The healthcare provider should first perform a rapid assessment. A rapid assessment is a quick visual survey to ensure safety, to form an initial impression about the patient's condition, and to check for responsiveness, breathing and a pulse if the patient appears to be unresponsive.This would be followed by a primary assessment and then a secondary assessment.
