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. The patient's chart may provide historical information but does not reflect the current pain intensity the client is experiencing.
B. Visual observation for nonverbal signs of pain can be useful, especially for nonverbal patients, but self-reporting is the most accurate measure of pain intensity.
C. The client's self-report of pain severity is the gold standard for assessing pain intensity, as it reflects the individual’s personal experience of pain.
D. While the nature and invasiveness of the surgical procedure can provide context for expected pain levels, they do not replace the importance of the client's self-report in managing pain effectively.
Correct Answer is B
Explanation
A. Auscultating the area may not provide information about the dorsalis pedis pulse, which is a palpated pulse.
B. Using Doppler ultrasonography is the most appropriate next step to locate the dorsalis pedis pulse if it cannot be palpated, as it provides a non-invasive way to detect blood flow.
C. While documenting the absence of the pulse is necessary, it should be done after attempts to locate the pulse have been made.
D. It is not immediately necessary to ask a provider to assess the pulse; the nurse can use Doppler ultrasonography first to gather more information.
