Question 1

The presenting problem with Sinus Bradycardia is that:&#10;A)the P waves are irregular.&#10;B)the rate is too slow.&#10;C)the PRI is too long.&#10;D)the QRS is too wide.

Accepted Answer

Sinus Bradycardia is a sinus rhythm with a rate lower than 60 bpm. This can cause a decrease in cardiac output which can lead to symptoms such as dizziness, weakness or syncope. Therefore, the presenting problem with sinus bradycardia is that the rate is too slow.

Question 2

For Sinus Tachycardia,the QRS complex should be less than ________ sec.&#10;A)0.01&#10;B)0.12&#10;C)0.18&#10;D)0.20

Accepted Answer

The QRS complex duration in sinus tachycardia should be within normal limits, which is less than 0.12 sec. Options A, C, and D are incorrect as they suggest a shorter or longer QRS duration than what is normal for sinus tachycardia.

Question 3

In Normal Sinus Rhythm,the PR interval must fall between ________ sec.&#10;A)0.04-0.06&#10;B)0.08-0.22&#10;C)0.12-0.20&#10;D)0.20-0.60

Accepted Answer

In Normal Sinus Rhythm, the PR interval (time from the beginning of the P wave to the beginning of the QRS complex) should fall between 0.12-0.20 seconds (or 3-5 small squares on ECG paper). This interval represents the conduction of electrical impulses through the atrioventricular (AV) node, and a prolonged PR interval may indicate AV block or other conduction abnormalities. The other options are incorrect as they either represent intervals outside of the normal range or include extremes that would indicate potentially dangerous conditions.

Question 4

The term &#34;tachycardia&#34; means:&#10;A)slow heart.&#10;B)fast heart.&#10;C)normal heart.&#10;D)sinus rhythm.

Accepted Answer

Tachycardia refers to a heart rate that is faster than normal.

Question 5

In Sinus Arrhythmia,the heart rate is usually ________ bpm.&#10;A)less than 60&#10;B)less than 80&#10;C)60-100&#10;D)greater than 100

Accepted Answer

Sinus arrhythmia is a type of irregular heart rhythm where the heart rate varies between inhalation and exhalation, causing a slightly faster heart rate during inhalation and a slightly slower heart rate during exhalation. The normal heart rate range for sinus arrhythmia is considered to be between 60-100 bpm.

Question 6

The rate for Sinus Bradycardia is ________ bpm.&#10;A)less than 60&#10;B)more than 100&#10;C)between 60 and 100&#10;D)equal to 110

Accepted Answer

Sinus Bradycardia is defined as a sinus rhythm with a resting heart rate of less than 60 bpm.

Question 7

In Normal Sinus Rhythm,the heart rate is ________ bpm.&#10;A)40-60&#10;B)60-100&#10;C)80-120&#10;D)100-120

Accepted Answer

Normal Sinus Rhythm typically has a heart rate of 60-100 beats per minute.

Question 8

When a sinus rhythm has a QRS complex of 0.12 sec or greater,you know that this is an abnormality and would note that it has:&#10;A)a wide QRS.&#10;B)accelerated ventricular conduction.&#10;C)Purkinje disease.&#10;D)sinus conduction defect.

Accepted Answer

A QRS complex of 0.12 sec or greater indicates a wide QRS complex, which is an abnormality.

Question 9

The presenting problem with Sinus Tachycardia is that:&#10;A)the rhythm is irregular.&#10;B)the rate is too fast.&#10;C)the PRI is not constant.&#10;D)the QRS is too narrow.

Accepted Answer

Sinus Tachycardia is a regular rhythm with a rate greater than 100 beats per minute. The problem is that the heart rate is too fast and can potentially decrease cardiac output and tissue perfusion.

Question 10

For all rhythms that originate in the sinus node,you would expect the P wave in Lead II to be:&#10;A)inverted or flattened.&#10;B)biphasic or notched.&#10;C)characteristically peaked.&#10;D)upright and uniform.

Accepted Answer

Sinus rhythms originate in the sinus node, and therefore the P wave should be upright and uniform in Lead II.

Question 11

The presenting problem with Sinus Arrhythmia is that:&#10;A)the rhythm is irregular.&#10;B)the PRI varies from beat to beat.&#10;C)the PRI is too long.&#10;D)the QRS is too wide.
