The nurse responds to a call for assistance with a patient in pulseless ventricular tachycardia. The nurse prepares for what first-line treatment for this rhythm?
Defibrillation
Antiarrhythmic medication
Synchronized cardioversion
Pacemaker
The Correct Answer is A
A. Pulseless ventricular tachycardia requires immediate defibrillation to restore a perfusing rhythm.
B. Antiarrhythmic medications are not typically effective for pulseless ventricular tachycardia as the heart is not effectively pumping blood.
C. Synchronized cardioversion is used for certain tachyarrhythmias with a pulse but is not appropriate for pulseless ventricular tachycardia.
D. A pacemaker is not indicated for pulseless ventricular tachycardia as it does not address the underlying issue of cardiac arrest.

Correct Answer is B
Explanation
A. In the oliguric phase of acute kidney injury, fluid intake may need to be restricted rather than encouraged to prevent fluid overload.
B. Hourly intake and output monitoring is crucial for managing fluid balance and assessing the progression of kidney injury. Close monitoring can help prevent fluid overload, which is a risk due to the reduced urine output. It also aids in the timely adjustment of fluid administration and the detection of any changes in the client's condition that may necessitate intervention.
C. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are contraindicated in acute kidney injury as they can further impair renal function.
D. In the oliguric phase, protein intake may need to be restricted to reduce the workload on the kidneys and minimize azotemia. A high-protein diet can increase the burden on already compromised kidneys due to the increased production of urea, a byproduct of protein metabolism that requires excretion by the kidneys.
Correct Answer is A
Explanation
A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.
