Calcium-channel blockers act primarily on?

ARTERIES TO ARTERIOLES
Large-lumen vessels in the arteriole system are affected. The advantage of
this action is that both systolic and diastolic pressures are reduced and the
pt will not have a precipitous drop in BP. The BP may be lowered slightly
and cause a reflex baroreceptor response to increase HR to maintain CO
(cardiac output).
The possibility of microshock when handling a temporary pacemaker can be
minimized by:

Which of the following hemodynamic changes will occur with cardiac tamponade?
• Increased cardiac output
• Stroke volume decrease
• Contractility increases
• Decreased heart rate
Give this one a try later!
STROKE VOLUME DECREASE
Because the heart cannot adequately fill or eject its contents, stroke
volume (SV) decreases and causes a decreased cardiac output (CO).
Contractility decreases because the muscles cannot stretch and, therefore,
cannot contract effectively.
What do abnormal Q waves signify on a 12-lead EKG?

, Complete- thickness infarction of the myocardium
When tissue dies as a result of MI, it becomes electrically dead, causing the
opposing energy to become the dominant feature.
Partial- thickness myocardial death would be classified as a non-Q wave
MI.
when the PR interval is lengthened beyond the normal interval, it is called a __ ___ ___

(2xNa) + (glucose x 10)/180
The patient has markedly deep, rapid respirations with a fruity breath odor. Based on
the patient's history, the nurse will:

, What % of acute MIs may be considered "silent?"
Give this one a try later!
20%
Silent infarcts account for approximately 20% of all MIs. Silent infarcts are
often seen in patients who present atypically, such as the elderly and
persons with diabetes.
The most common new-onset dysrhythmias seen is a patient with pulmonary edema
is:

Atrial fibrillation
A Fib is the result of the constant stretching and disruption of normal
pathyways in the atrium due to inreased preload produced by the
pulmonary congestion.
What does AICD stand for?
Give this one a try later!
Automated implantable cardioverter/defibrillator
AICDs may be implanted in patients with recurrent ventricular tachycardia.
They can also be programmed to act as pacemakers.
