Your patient is in ventricular tachycardia with a heart rate of 124. His blood pressure is stable but he's complaining of mild dizziness. Appropriate treatment for THIS PATIENT AT THIS TIME is

amiodarone to decrease ventricular irritability and help convert the rhythm back to sinus.

If a pacemaker fails to fire, what is shown on the EKG?

Lack of a pacemaker spike where there should be one

Capture is evidenced on the EKG by the presence of

P waves or QRS complexes following the pacemaker spikes

A VOO pacemaker would pace the

ventricle, sense nothing, and have no response to sensed events since it cannot sense

A fixed-rate pacemaker

fires at its preset rate regardless of intrinsic beats

pace the atrium and the ventricle in succession

Your patient has his own P waves but no QRS complexes. His DDD pacemaker should

sense the intrinsic P waves and deliver QRS complexes to follow those P waves within a preset rate range

Which of the following describes undersensing?

The pacemaker fails to sense intrinsic beats and paces on top of them

Chapter 16

Question	Answer
Atropine	Increases Heart Rate
Beta-Blockers	Decreases Heart Rate and contractility
Propranolol (Iderol)	Is a Beta Blocker
Digitalis	Is a Cardiac Glycoside
Beta Blockers must be used with caution in patients with	Asthma or Chronic Lung Disease
Epineohrine (during a cardiac emergency) is given	Intravenously
Certain glaucoma medications can cause	Bradycardia
Asystole is treated with	Atropine and epinephrine
Atopine blocks the	effects of the Vegus Nerve
Hypoxia is treated with	oxygen
Diltiazem	Interfers with the movement of calcium ions through the cardiac cell membranes
Epinephrine increases	Blood Pressure
What increases tissue oxygenation?	Oxygen (duh) :)
46 yr old Male- No P waves or QRS complexes on a ECG (just flat line) should NOT be treated with	Propranolol
Atopine is approperiate medicine to give to increase a patients heart rate?	True
Your patient is in ventricular tachycardia with a heart rate of 124. His blood pressure is stable but he's complaining of mild dizziness. Appropriate treatment for THIS PATIENT AT THIS TIME is	amiodarone to decrease ventricular irritability and help convert the rhythm back to sinus.
Your patient is in pulseless ventricular tachycardia. Your first intervention should be	defibrillation
The first letter of the pacemaker code tells the	chamber paced
When a pacemaker fires, it creates what sign on the EKG?	A spike
If a pacemaker fails to fire, what is shown on the EKG?	Lack of a pacemaker spike where there should be one
Capture is evidenced on the EKG by the presence of	P waves or QRS complexes following the pacemaker spikes
The second letter of the pacemaker code tells the	chamber sensed
A transcutaneous pacemaker paces the heart	through the skin
A VOO pacemaker would pace the	ventricle, sense nothing, and have no response to sensed events since it cannot sense
The pacemaker's generation of an electrical impulse is called	firing
A fixed-rate pacemaker	fires at its preset rate regardless of intrinsic beats
DDD pacemakers	pace the atrium and the ventricle in succession
Your patient has his own P waves but no QRS complexes. His DDD pacemaker should	sense the intrinsic P waves and deliver QRS complexes to follow those P waves within a preset rate range
Which of the following describes undersensing?	The pacemaker fails to sense intrinsic beats and paces on top of them
