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 suspect that improper BVM technique is being used? {Ans: Pneumothorax}A patient's ECG reveals a narrow QRS complex with a regular rhythm, indicating a narrow-complex supraventricular tachyarrhythmia. The patient is not showing signs of hemodynamic compromise. Which intervention would be initiated first if it does not delay other interventions? {Ans: Vagal maneuvers}A patient with suspected acute coronary syndromes (ACS) has a pulse oximetry reading of 86% and is given supplemental oxygen. The provider determines that the supplemental oxygen dose is correct based on which SaO2 level? {Ans: 93%}A patient with dyspnea, inadequate blood pressure and a change in mental status arrives at the emergency department. The healthcare team completes the necessary assessments and begins to care for the patient, including initiating cardiac monitoring and pulse oximetry; providing supplemental oxygen and ensuring adequate ventilation; and obtaining vascular access. The team reviews the patient's ECG rhythm strip, as shown in the following figure. Which agent would the team most likely administer? {Ans: Atropine 1 mg every 3 to
