How should the nurse identify the rhythm shown in the diagram?

C:\Users\USER\AppData\Local\Microsoft\Windows\INetCache\Content.MSO\411E6DD3.tmp

A.

ventricular tachycardia

B.

asystole

C.

normal sinus rhythm

D.

ventricular fibrillation

Answer and Explanation

The Correct Answer is A

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. The bell of the stethoscope is best used to listen for low-pitched sounds, including some types of murmurs, and can help assess the quality and intensity of a cardiac murmur.

B. While palpation can provide some information about the heart's function (such as thrills), it is not the primary method for assessing the quality of a murmur.

C. A Doppler ultrasound device is used for measuring blood flow and can help in assessing murmurs but does not provide the quality assessment needed for characterizing a murmur.

D. Percussion is not typically used to evaluate murmurs; it is more useful for assessing the size and borders of organs.

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.
