ALS COMPLETE QUESTIONS AND
VERIFIED SOLUTIONS
◉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? Answer: 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? Answer: 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? Answer: 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? Answer: 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? Answer:
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? Answer: 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? Answer: Ventricular
tachycardia
◉A patient with acute renal failure experiences cardiac arrest. Just
before the cardiac arrest, the patient's ECG showed peaked T waves.
