medication administration with abolus of fluid. How much wouldtheteam member
give? -answer- 10 to 20 mL
The resuscitation team suspects that hyperkalemia is the cause of cardiac
arrest in a patientbrought totheemergencydepartment. Whichfinding ona12-
lead ECG would confirm this suspicion? – answer - 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 carefor thepatient, including initiatingcardiac 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? – answer - Atropine 0.5 mg every 4 to 5
minutes
A patient experiencing an unstable bradyarrhythmia does not respond to
atropine or transcutaneouspacing. Whichintervention wouldthehealthcare
providerusenext? - answer- Administration of an epinephrine infusion
A patient's ECG reveals a tachyarrhythmia. The patient is hemodynamically stable
and has aheart rate ranging from 120 to 135 beats per minute. Based onthe
findings of the secondary assessment, whichstatement(s)by thepatient would
theteam interpretas a possible contributing cause? - answer-1. "I've had a
terrible cold with a horrible cough and fever the past week."
2. "I'vebeensoanxious lately becauseI just lost my job."
3. "I'vebeenvomitingfor thepast2days from agastrointestinalbug."
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? -
answer-Vagal maneuvers
A patient in the telemetry unit is stable. Cardiac monitoring indicates the patient
has ventricular tachycardia with apulse. Furtherassessment reveals that the
corrected QT interval is greater than 0.46 seconds. Which treatment would be
appropriate at this time? - answer-Synchronized cardioversion
An ECG strip of a patient in the emergency department reveals the following
rhythm. Whichfeature would thehealthcareprovider interpretas indicating
atrial fibrillation? - answer-Absence of discrete P waves and presence of
irregularly irregular QRS complexes
A 30-year-old patient has beenbrought to the emergency department infull
cardiac arrest. Thecardiac monitorshows thefollowing rhythm. Interpretationof
this rhythm would suggest which of the following as a possible precipitating
factor? - answer- Electrocution
Cardiac monitoring ofapatient incardiacarrest reveals ventricular fibrillation.
What intervention would the team perform next? - answer-Administer 1 shock.
A patient has experienced return of spontaneous circulation (ROSC) after
cardiac arrest. Thehealthcareteam is conducting a secondary assessment to
determine thepossible cause of the patient's cardiac arrest. Beforethe arrest,
the patient exhibited jugular venous distension, cyanosis, apneaand
hyperresonance on percussion. The patient was alsodifficult toventilateduring
theresponse. Theteam would most likely suspect which condition as the cause?
- answer-Tension pneumothorax
A patient incardiacarrest experiences returnof spontaneous circulation. Aspart
of
post-cardiacarrestcare, thepatient 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? - answer-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 Scalescoreof 7. Targeted temperature management is initiated.
Which method(s) would beappropriatefor theresuscitationteam touse? -
answer-1. Applying cooling blankets to the patient's body
2. Giving anice-cold IVfluidbolus
3. Usinganendovascular catheter
A 40-year-old patient in the waiting room of the primary care provider's office
approachesastaff memberand says, "I'm having really severe, crushing chest
painthat is moving to both my arms." The patient is diaphoretic and dyspneic.
Which action would be appropriate for the staff member to take? - answerActivate the emergency medical services system.
A patient with suspected acute coronary syndromes (ACS) is placed on a cardiac
monitor. Thepatient is complainingofdyspnea and isgiven supplemental oxygen.
Theproviderdetermines that theoxygenis effectivebasedon which SaO2level?
-answer- 95%
A 35-year-old female patient's ECG is consistent with STEMI. The ECG reveals a
new ST-segmentelevationat theJpoint inleadsV2andV3 of at least whichsize?
-answer0.15 mV
A patient with STEMI is experiencing chest pain that is refractory to sublingual
nitroglycerin. Intravenous nitroglycerin is prescribed. When administering this
medication, it would betitrated to maintain whichsystolic bloodpressure? -
answer-90 mmHg
A patient experiencing STEMI comes tothe emergencydepartmentof alarge
medical center at 9:30 p.m. The patient states that the symptoms started about
8 p.m. After confirming thediagnosis andinitiatingcare, thehealthcareteam
schedules thepatient for percutaneous coronary intervention (PCI). The facility
is capable of administering PCI. To achieve the best outcomes, therapy should be
administered to this patient by which time? - answer-11:00 p.m.
A patientpresents totheemergencydepartment with mild to moderate
recurrentchest pain, without any nausea or vomiting. A 12-lead ECG is obtained
and shows ST- segment depression with transient T-wave elevation indicative of
NSTE-ACS. Cardiac enzyme levels are obtained and are not elevated. These
findings suggest which condition? - answer-Unstable angina
A patient isbeing treated intheemergencydepartment and isdetermined to
have NSTE-ACS. Invasive management is planned based on which finding? -
answer-Ventricular tachycardia
A patient presents to the emergency department with suspected ACS.
