Dysrhythmias, RRTs, Code Management Flashcards
A pts heart rhythm is extremely irregular and there are no discernible P waves. The ventricular rate is 90 bpm and the pt is hemodynamically stable. You realize that the pts rhythm is:
Atrial Fibrillation
Sinus bradycardia is a symptom of which of the following:
Hypothermia, beta blocker medication, calcium channel blocker medication, and athletic conditioning
You are calculating the rate for a regular rhythm. There are 20 small boxes between each P wave and 20 small boxes between each R wave. What is the ventricular rate?
1500/20=75
Your patient’s heart rate is 165 beats per minute. The cardiac monitor shows a rapid rate with narrow QRS complexes. The P waves cannot be seen, but the rhythm is regular. Your patient’s BP has dropped from 124/62 mm Hg to 78/30 mm Hg. Your patient’s skin is cold and diaphoretic and your patient is complaining of nausea. What is your priority action
Prepare your pt for an emergent cardioversion
Your patient’s heart rhythm shows an inverted P wave with a PR interval of 0.06 seconds. The heart rate is 54 beats per minute. You recognize that the rhythm is due to the
Loss of sinus node activity
You are caring for a patient who has atrial fibrillation. Sequelae that place your patient at greater risk for mortality/morbidity include which of the following
decreased cardiac output, CVA, and pulmonary emboli
Your patient is admitted to the coronary care unit with an inferior wall myocardial infarction and develops symptomatic bradycardia with premature ventricular contractions every third beat (trigeminy). Which medication would be a priority medication to administer?
Atropine
You are assisting in a code. In what correct locations would you place the paddles for anterior defibrillation?
Second intercostal space, right sternal border, and fifth intercostal space, left midaxillary line
The code team has just defibrillated a patient in ventricular fibrillation. Following CPR for 2 minutes, what is the next action to take?
Assess rhythm and pulse
During a code situation the nurse would prepare to use which preferred IV fluid?
Normal Saline
Do you shock with asystole?
No, if no pulse do not shock give epi
During a code situation, the nurse would prepare to use which preferred IV fluid?
Normal Saline
P wave
Atrial Depolarization, normaly indicates firing of the SA node
QRS complex
Ventricular depolarization
PR Interval
Atrial depolarization
Short: impulse from AV junction
Long: 1st degree AV block
