Which of the following is used to evaluate the calcium in coronary arteries?

Correct! Wrong!

Explanation:
The evaluation of coronary artery calcium is done using electron beam computed tomography. Spiral
tomography is another option.

What does the Holter EKG monitoring test function entail?

Correct! Wrong!

Explanation:
Holter EKG monitoring keeps tabs on EKG abnormalities as they happen during the day. The client keeps
track of the tasks completed during the 24-hour testing period, and the results are compared to the recorded
tasks to determine which ones produce aberrant reactions.

The Mason Likar modification is what?

Correct! Wrong!

Explanation:
The 12-lead EKG electrode placement is altered with the Mason Likar modification. This is occasionally
required because of electrode movement, muscular activity, or breathing.

What is the method where a balloon is used to flatten plaque up against an arterial wall to provide more room inside the artery for better blood flow?

Correct! Wrong!

Explanation:
A balloon is used in the procedure known as percutaneous transluminal coronary angioplasty (PTCA) to
flatten plaque up against an artery's wall, opening up more space for better blood flow. In order to remove
the plaque, the atherectomy employs a revolving shaver and the laser angioplasty uses photon pulses. Parts
of the artery that are beyond repair using other less intrusive techniques are totally rebuilt during a bypass.

The horizontal squares on an EKG measure what?

Correct! Wrong!

Explanation:
On an EKG, the horizontal squares represent duration. This is based on the fact that cardiac electrical
potentials move at a speed of 25 mm/s.

Which of the following statements about a T wave is true?

Correct! Wrong!

Explanation:
A myocardial infarction or hyperkalemia may be indicated by a T wave with prominent peaks. Normally, the
waves that characterize ventricular depolarization are not symmetrical.

An ST depression accompanied by strong U waves and flattened T waves results from what electrolyte abnormality?

Correct! Wrong!

Explanation:
An ST depression with pronounced U waves and flattened T waves is brought on by hypokalemia.
