All questions

Question 1

A patient care technician observes occasional wide, bizarre QRS complexes interrupting an otherwise normal sinus rhythm at 70 beats per minute. These abnormal complexes occur every 6-8 beats, are not preceded by P waves, and are followed by a compensatory pause. The patient denies symptoms. What should be documented and reported?

  1. Unifocal premature ventricular contractions with compensatory pauses requiring monitoring but no immediate intervention needed (correct answer)
  2. Premature atrial contractions with aberrant conduction causing wide complexes and requiring electrolyte assessment
  3. Interpolated ventricular ectopy with normal sinus rhythm requiring immediate cardiac enzyme evaluation
  4. Ventricular escape beats indicating underlying sinus node dysfunction requiring permanent pacemaker consideration
Explanation: Wide, bizarre QRS complexes without preceding P waves and followed by compensatory pauses are classic premature ventricular contractions (PVCs). The frequency (every 6-8 beats) and unifocal appearance (assuming similar morphology) suggests these are benign in an asymptomatic patient but should be documented and reported for nursing assessment. Choice B is incorrect because PACs with aberrancy would still have preceding P waves. Choice C uses incorrect terminology (interpolated) and suggests unnecessary testing. Choice D misidentifies PVCs as escape beats, which occur during bradycardia.

Question 2

A patient care technician notices the cardiac monitor showing a rhythm at 180 beats per minute with wide QRS complexes (>0.12 seconds), no discernible P waves, and slight irregularity in the R-R intervals. The patient appears diaphoretic and reports severe chest pain. What is the most critical action?

  1. Document ventricular tachycardia and prepare for possible emergency cardioversion while immediately notifying the nurse (correct answer)
  2. Obtain a 12-lead EKG to differentiate between supraventricular tachycardia with aberrancy and ventricular tachycardia
  3. Administer oxygen and reassess in 5 minutes as this appears to be sinus tachycardia with bundle branch block
  4. Check electrode placement and repeat monitoring as artifact commonly causes wide complex tachycardia appearance
Explanation: Wide complex tachycardia at 180 bpm with hemodynamic compromise (diaphoresis, chest pain) should be treated as ventricular tachycardia until proven otherwise. This is a life-threatening emergency requiring immediate nursing notification and preparation for cardioversion. Choice B delays potentially life-saving treatment. Choice C misidentifies the rhythm and suggests inappropriate delay. Choice D incorrectly assumes artifact when the patient has clear symptoms of hemodynamic compromise consistent with the rhythm observed.

Question 3

During continuous cardiac monitoring, a patient care technician notices the rhythm suddenly changes from normal sinus rhythm to an irregular pattern with no discernible P waves and QRS complexes occurring at varying intervals between 80-120 per minute. The patient reports feeling "fluttering" in their chest. Which dysrhythmia should be reported?

  1. Sinus arrhythmia with respiratory variation causing the patient's subjective symptoms of palpitations
  2. Atrial fibrillation with controlled ventricular response requiring immediate nursing notification and assessment (correct answer)
  3. Premature atrial contractions with compensatory pauses creating the irregular pattern and symptoms
  4. Wandering atrial pacemaker with variable P wave morphology causing the irregular rhythm pattern
Explanation: The absence of discernible P waves with an irregularly irregular rhythm and controlled ventricular rate (80-120) is characteristic of atrial fibrillation. The patient's complaint of "fluttering" supports this diagnosis. This requires immediate reporting as it increases stroke risk and may need anticoagulation. Choice A is incorrect because sinus arrhythmia maintains visible P waves. Choice C would show identifiable premature beats with compensatory pauses. Choice D would show varying P wave shapes but still visible P waves.

Question 4

While monitoring a post-operative patient, a patient care technician notes a rhythm with a rate of 150 beats per minute, narrow QRS complexes, and what appears to be a "sawtooth" pattern instead of normal P waves. The patient appears anxious and reports mild chest discomfort. What dysrhythmia requires immediate reporting?

  1. Supraventricular tachycardia with aberrant conduction causing the unusual baseline pattern and rapid rate
  2. Atrial flutter with 2:1 conduction requiring immediate intervention due to the rapid ventricular response (correct answer)
  3. Sinus tachycardia with baseline artifact from patient movement creating the sawtooth appearance on monitor
  4. Atrial fibrillation with rapid ventricular response and coarse fibrillatory waves mimicking flutter pattern
Explanation: The sawtooth pattern is pathognomonic for atrial flutter, and a ventricular rate of 150 suggests 2:1 conduction (atrial rate ~300). This rapid rate can compromise cardiac output and requires immediate nursing notification for possible cardioversion or rate control medications. Choice A doesn't explain the sawtooth pattern. Choice C incorrectly attributes the characteristic flutter waves to artifact. Choice D is incorrect because atrial fibrillation shows irregular fibrillatory waves, not the organized sawtooth pattern of flutter.

Question 5

A patient care technician observes a rhythm strip showing QRS complexes occurring at a rate of 45 beats per minute, with P waves present at a rate of 75 beats per minute, but no consistent relationship between P waves and QRS complexes. What is the priority action?

  1. Document the finding as sinus bradycardia with occasional premature atrial contractions and continue monitoring
  2. Adjust the EKG machine sensitivity settings as the inconsistent P-QRS relationship suggests calibration error
  3. Immediately notify the nurse of complete heart block as this rhythm may require emergency pacing intervention (correct answer)
  4. Reposition the patient to improve electrode contact since poor connection often causes P wave variability
Explanation: This describes third-degree (complete) heart block where P waves and QRS complexes occur independently with no relationship between them. The slow ventricular rate of 45 bpm indicates the ventricles are being paced by a junctional or ventricular escape rhythm. This is a life-threatening condition requiring immediate notification as the patient may need emergency pacing. Choice A incorrectly identifies this as sinus bradycardia. Choice B assumes equipment malfunction when the findings are clinically consistent. Choice D suggests artifact when the pattern described is pathological.

Question 6

A patient care technician observes a rhythm strip showing completely chaotic, irregular deflections with no identifiable QRS complexes, P waves, or organized electrical activity. The rhythm appears as random, coarse oscillations. The patient is unresponsive and pulseless. What life-threatening dysrhythmia requires immediate emergency response?

  1. Polymorphic ventricular tachycardia requiring immediate synchronized cardioversion and advanced life support
  2. Atrial fibrillation with rapid ventricular response requiring rate control and anticoagulation therapy
  3. Multifocal atrial tachycardia requiring electrolyte replacement and continuous cardiac monitoring
  4. Ventricular fibrillation requiring immediate CPR and defibrillation per ACLS protocols (correct answer)
Explanation: The description of chaotic, disorganized electrical activity with no identifiable waveforms and an unresponsive, pulseless patient indicates ventricular fibrillation. This is a life-threatening emergency requiring immediate CPR and defibrillation according to ACLS protocols. Choice A describes organized polymorphic VT which would show identifiable QRS complexes. Choices B and C are supraventricular rhythms that would not cause cardiac arrest and would show some organized electrical activity.
