How should the nurse identify the rhythm shown in the diagram?
ventricular tachycardia
asystole
normal sinus rhythm
ventricular fibrillation
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 C
Explanation
A. Heroin use is generally associated with intravenous use and is less commonly linked to nasal septum perforation.
B. Ecstasy (MDMA) is primarily used in tablet form and is not typically associated with nasal use that would cause septal perforation.
C. Cocaine is frequently snorted, which can lead to irritation and damage to the nasal passages and septum, resulting in perforation.
D. Marijuana is usually smoked rather than snorted, and it is not commonly associated with nasal septum perforation.
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.
