A nurse is teaching about the risk factors of developing a stroke with a group of older adult clients. Which nonmodifiable risk factors should the nurse include in the teaching?
Obesity
Race
History of smoking
History of hypertension
The Correct Answer is B
A. Obesity is a modifiable risk factor, as it can be addressed through lifestyle changes such as diet and exercise.
B. Race is a nonmodifiable risk factor; certain races may have a higher risk of stroke due to genetic and environmental factors.
C. History of smoking is a modifiable risk factor because individuals can choose to quit smoking to reduce their risk of stroke.
D. History of hypertension is also a modifiable risk factor; while having high blood pressure increases the risk of stroke, it can be managed with lifestyle changes and medications.

Correct Answer is A
Explanation
A. Ventricular tachycardia: Ventricular tachycardia (VT) is identified by a regular, fast rhythm with wide QRS complexes, typically without visible P waves. This rhythm often appears as consecutive, large, uniform waves, which is consistent with what is seen in the diagram.
B. Asystole: Asystole is characterized by a flat line, indicating no electrical activity, which is not present in this strip.
C. Normal sinus rhythm: Normal sinus rhythm would show identifiable P waves, a normal QRS complex, and a regular rate, which are not observed here.
D. Ventricular fibrillation: Ventricular fibrillation appears as chaotic, irregular waveforms with no clear QRS complexes or organization, which does not match the rhythm shown.
Correct Answer is A
Explanation
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.
