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 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","C","D"]
Explanation
A. Decreased urine output: While not a direct sign of pneumonia, decreased urine output can be an objective finding indicative of dehydration, which often accompanies infections like pneumonia.
B. Headache: Although the client has a headache, it is a subjective symptom rather than an objective finding and is not a primary indicator of pneumonia.
C. Respiratory assessment: The respiratory assessment reveals shortness of breath, crackles in the right lower lobe, and tachypnea, which are commonly associated with pneumonia.
D. Chest X-ray: The chest X-ray shows areas of increased density and infiltrates in the right lower lobe, a hallmark finding that indicates pneumonia.
E. Religion: This does not relate to the clinical findings associated with pneumonia.
F. Bowel sounds: Normal bowel sounds are not indicative of pneumonia.
G. Perception of needles: This is irrelevant to the diagnosis of pneumonia.
