NRP571 Advanced Health Assessment IIand Clinical Procedures Week 5 Quiz Question 1Atrial fibrillation is characterized by _____. an erratic, wavy baseline and irregular ventricular rhythm "saw-tooth"- or "picket-fence"-shaped waveforms preceding each QRS one P wave before each QRS and a regular ventricular rate of 60 to 100 beats/min P waves occurring before, during, or after the QRS complex; when seen, they are inverted

Question 2Which of the following are possible causes of sinus bradycardia?

Elevated temperature, pain Increased intracranial pressure, beta-blocker overdose Hypoxia, fright, caffeine-containing beverages Hypovolemia, administration of sympathomimetics Question 3An ECG rhythm strip shows a regular ventricular rhythm at a rate of 30 beats/min, more P waves than QRS complexes (the P waves occur regularly), a variable PR interval, and a QRS duration of 0.14 seconds. This rhythm is _____. 2:1 AV block third-degree AV block second-degree AV block type I second-degree AV block type II

Question 4How are frequent PACs usually managed?

Defibrillation Synchronized cardioversion Correcting the underlying cause Administration of medications such as atropine or epinephrine

Question 5What is meant by the term pulseless electrical activity (PEA)?

A chaotic rhythm that is likely to degenerate into cardiac arrest An organized rhythm on the cardiac monitor (other than VT), although a pulse is not present A slow rhythm with a wide QRS complex A flat line on the cardiac monitor

Question 6Which of the following are possible causes of sinus tachycardia?

Hypothermia, hypovolemia Hypoxia, calcium channel blocker overdose Fever, pain, anxiety Vomiting, vagal maneuvers Question 7A delta wave is an ECG characteristic associated with which of the following dysrhythmias? Junctional rhythm AV nodal reentrant tachycardia (AVNRT) Wolff-Parkinson-White (WPW) syndrome Accelerated idioventricular rhythm (AIVR) Question 8 Tall, peaked T waves observed on the ECG are most commonly seen in patients with _____. hypokalemia hyponatremia hyperkalemia hypernatremia Question 9An ECG rhythm strip shows a ventricular rate of 46 bpm, a regular rhythm, a PR interval of 0.14 seconds, a QRS duration of 0.06 seconds, and one upright P wave before each QRS. This rhythm is _____. sinus rhythm sinus bradycardia sinus arrest sinoatrial block Question 10To determine whether the ventricular rhythm on an ECG tracing is regular or irregular, compare _____ intervals. PR R to R TP P to
