Question 1.
Potassium and which of the following are needed in order for the heart to function
normally?
Chloride
Creatinine
Calcium
Magnesium
Correct Answer: Calcium
Question 2.
________________ is a complication in which the pacemaker does not send electrical
impulse to the myocardium. In this complication pacemaker intervals are irregular and
the impulse is slower than the set rate. There is no pacemaker spike seen.
Correct Answer: Malfunctioning
Question 3.
There are 3 electrolytes which the heart needs to function properly:
1. _________
2. ________
3. _________
If one of these three are lacking, the heart doesn't function well.
Correct Answer: Potassium, Calcium, Sodium
Question 4.
Saying words correctly would be considered ___________. Speaking clearly would be
considered __________.
Correct Answer: pronunciation, enunciation
• Premature atrial contractions are rarely dangerous but in a patient with
which of the following conditions, they can serve as an early sign of heart
failure or electrolyte imbalance?
Nonconductor premature atrial contractions
Hypoxia
Acute myocardial infarction
Pulmonary disease -✓✓Acute myocardial infarction
Question 5.
Patients with an __________ ___________ ____________, premature atrial contractions can
serve as an early sign of heart failure or an electrolyte imbalance. Premature atrial
, contractions in patient's with heart disease can lead to serious arrhythmias such as
atrial flutter and atrial fibrillation.
Correct Answer: Acute myocardial infarction
Question 6.
Which of the following does the CDC recommend that healthcare workers not have?
Long hair
Short nails
Artificial nails
All of the above
Correct Answer: Artificial nails
Question 7.
The CDC recommends that healthcare providers not have _____________ ________ as they
are more apt to harbor gram-negative pathogens than natural nails, both before and
after proper hand washing techniques. The CDC recommends that natural nails be no
longer than 1/4 inch long as they can harbor pathogens at longer lengths.
Correct Answer: Artificial nails
Question 8.

deflects which direction? Upward
Right angle
Downward
Left angle
Correct Answer: Downward
Question 9.
As an electrical current travels toward the negative pole, the waveform deflects in a
__________ direction. When the current flows perpendicular to the lead, the waveform
can be small or biphasic. As the current travels toward the positive pole, the waveform
deflects in an ________ direction.
Correct Answer: downward, upward
