A patient is brought into the ED. The patient doesn't have a pulse. The cardiac monitor shows
the following rhythm.
V. Tach.
A patient with acute renal failure experiences cardiac arrest. Just before the cardiac arrest, the
patient's EKG showed peaked T waves. What might be causing the patients cardiac arrest?
Hyperkalemia
A member of the resuscitation team is preparing to defibrillate a patient in cardiac arrest using a
biphasic defibrillator. The team member would set the energy dose according to the
manufacturer's recommendations, which is usually:
120-200 joules
A member of the resuscitation team is preparing to administer medications intravenously to a
patient in cardiac arrest. The team member follows each medication administration with a
normal saline flush. How much would the team member give?
10-20 ml
A 30YO patient has been brought to the ED in cardiac arrest. The cardiac monitor shows the
following rhythm. Interpretation of this rhythm would suggest which of the following as a
possible precipitating factor?
, Electrocution
Cardiac monitoring of a patient in cardiac arrest reveals Ventricular Fibrillation. In addition to
high quality CPR, what intervention should be priority?
Defibrillation
The resuscitation team suspects that hyperkalemia is the cause of cardiac arrest in a patient
brought to the ED. Which finding on a 12 lead would confirm this?
Wide complex ventricular rhythm & tail, peaked T waves.
A patient has experienced ROSC after cardiac arrest. The healthcare team is conducting a
secondary assessment to determine the possible cause of the patients cardiac arrest. Before the
arrest, the patient exhibited JVD, cyanosis, apnea and hyperresonance on percussion. The team
would most likely suspect which condition as the cause?
Tension pneumothorax
A patient in cardiac arrest experiences ROSC. As part of post-cardiac arrest, the patient is
receiving mechanical ventilation at an initial rate of 10 breaths/min and a FiO2 of 0.30. Which
findings would indicate the need for change in the ventilator settings to optimize the patients
ventilation and oxygenation?
PaCO2 48mmHg
SaO2 90%
ETCO2 55mmHg
After cardiac arrest and successful resuscitation, the patient has a ROSC. The patient is unable to
follow verbal commands. TTM is initiated. Which methods would be appropriate for the
resuscitation team to use?
•Giving an Ice cold IV fluid bolus
•Applying cooling blankets to the pt's body
•Using an endovascular catheter
A patient with suspected acute coronary syndromes has a pulse oximetry of 86% and is given
supplemental O2. The provider determines that the supplemental O2 dose is correct based on
which SaO2 level?
93%
A 35YO female patients EKG is consistent with STEMI. The EKG reveals a new ST elevation at the
J point in leads V2 & V3 of at least which size?
