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 D
Explanation
A. Flexion refers to bending the joint, which does not apply when turning the palm down.
B. Supination is the movement of turning the palm up, which is the opposite of what is being tested here.
C. Rotation refers to the circular movement around a central point, but it does not specifically describe the action of turning the palm down.
D. Pronation is the movement of turning the palm down, which is exactly what the client is doing when asked to perform this maneuver.
Correct Answer is B
Explanation
A. Observing for facial symmetry assesses cranial nerves VII (facial nerve), not cranial nerve III.
B. Cranial nerve III (oculomotor nerve) is responsible for eye movement and pupillary response, making checking the pupillary response to light the correct action.
C. Testing visual acuity primarily assesses cranial nerve II (optic nerve), not cranial nerve III.
D. Eliciting the gag reflex is associated with cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve III.
