What is the rate on the rhythm strip in the image below?
90
110
73
50
The Correct Answer is A
A. To determine the heart rate from a rhythm strip, you can count the number of R-R intervals in a set time frame (typically 6 seconds) and multiply by 10 to convert to beats per minute. If the rhythm is regular, you can also use the 300 method by dividing 300 by the number of large squares between R waves. In this case, the rate is calculated to be 90 beats per minute.
B. A heart rate of 110 beats per minute would be classified as tachycardia and is not supported by the observed intervals.
C. A heart rate of 73 beats per minute would be a normal resting heart rate but does not match the calculation from the rhythm strip.
D. A heart rate of 50 beats per minute would indicate bradycardia, which is not reflected in this rhythm strip.

Correct Answer is ["D","F"]
Explanation
A. This statement indicates complete paralysis of both sides, which does not apply to hemiparesis, where one side is affected.
B. While this could describe some patients, it does not accurately represent "complete" right-sided hemiparesis.
C. This option is a repeat and also does not accurately reflect complete right-sided hemiparesis.
D. Weakness on the right side of the face and tongue is consistent with right-sided hemiparesis, as the stroke may affect motor control in those areas.
E. This describes a client who is less severely affected and may not apply to someone with complete right-sided hemiparesis.
F. Weakness on the right side of the body is a direct characteristic of right-sided hemiparesis.
Correct Answer is C
Explanation
A. This would show a regular rhythm with a consistent rate (60-100 bpm) and clear P waves before each QRS complex, which is not present in asystole.
B. This indicates a slow heart rate (below 60 bpm) but would still display P waves and QRS complexes; asystole shows no electrical activity.
C. This is the correct interpretation as it represents a flatline on the ECG, indicating no electrical activity in the heart.
D. This would show a rapid heart rate (above 100 bpm) with present P waves, which is not the case in asystole.
