ALS/ACLS - Red Cross Final Exam2022/2023- 48 Questions With Answers
Correctly Verified!!!
The resuscitation team suspects that hyperkalemia is the cause of cardiac
arrest in a patient brought to the emergency department. Which finding on a
12-lead ECG would confirm this suspicion? - -Wide-complex ventricular
rhythm or tall, pointed T waves
-A patient with dyspnea 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, pulse oximetry, supplemental oxygen and 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? - -Atropine 0.5
mg every 4 to 5 minutes
-A patient experiencing an unstable bradyarrhythmia does not respond to
atropine or transcutaneous pacing. Which intervention would the healthcare
provider use next? - -Administration of an epinephrine infusion
-A patient's ECG reveals a tachyarrhythmia. The patient is hemodynamically
stable and has a heart rate ranging from 120 to 135 beats per minute. Based
on the findings of the secondary assessment, which statement(s) by the
patient would the team interpret as a possible contributing cause? - -1. "I've
had a terrible cold with a horrible cough and fever the past week."
2. "I've been so anxious lately because I just lost my job."
3. "I've been vomiting for the past 2 days from a gastrointestinal bug."
-A patient's ECG reveals a narrow QRS complex with a regular rhythm,
indicating a narrow-complex supraventricular tachyarrhythmia. The patient is
hemodynamically stable. Which intervention would be initiated first? - -Vagal
maneuvers
-A patient in the telemetry unit is stable. Cardiac monitoring indicates the
patient has ventricular tachycardia with a pulse. Further assessment reveals
that the corrected QT interval is greater than 0.46 seconds. Which treatment
would be appropriate at this time? - -Synchronized cardioversion
-An ECG strip of a patient in the emergency department reveals the
following rhythm. Which feature would the healthcare provider interpret as
indicating atrial fibrillation? - -Absence of discrete P waves and presence of
irregularly irregular QRS complexes
-A patient is brought into the emergency department. The patient does not
have a pulse. The cardiac monitor shows the following rhythm. The team
interprets this as which condition? - -Ventricular tachycardia
, -A patient with acute renal failure experiences cardiac arrest. Just before the
cardiac arrest, the patient's ECG showed peaked T waves. What might be
causing the patient's 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 to 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 bolus of fluid. How much would the team
member give? - -10 to 20 mL
-A 30-year-old patient has been brought to the emergency department in
full 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. What intervention would the team perform next? - -Administer 1
shock.
-A patient has experienced return of spontaneous circulation (ROSC) after
cardiac arrest. The healthcare team is conducting a secondary assessment to
determine the possible cause of the patient's cardiac arrest. Before the
arrest, the patient exhibited jugular venous distension, cyanosis, apnea and
hyperresonance on percussion. The patient was also difficult to ventilate
during the response. The team would most likely suspect which condition as
the cause? - -Tension pneumothorax
-A patient in cardiac arrest experiences return of spontaneous circulation. As
part of post-cardiac arrest care, the patient is receiving mechanical
ventilation. Which finding(s) would indicate the need for change in the
ventilator settings to optimize the patient's ventilation and oxygenation? - -
1. SaO2 92%
2. PaCO2 35 mmHg
3. ETCO2 50 mmHg
-After cardiac arrest and successful resuscitation, the patient has a return of
spontaneous circulation. The patient is unable to follow verbal commands
and has a Glasgow Coma Scale score of 7. Targeted temperature
management is initiated. Which method(s) would be appropriate for the
resuscitation team to use? - -1. Applying cooling blankets to the patient's
body
2. Giving an ice-cold IV fluid bolus
3. Using an endovascular catheter
-A 40-year-old patient in the waiting room of the primary care provider's
office approaches a staff member and says, "I'm having really severe,
crushing chest pain that is moving to both my arms." The patient is
