Complete the following sentences with the list of drop down
The nurse assesses the client's rhythm on the monitor. The patient is unresponsive with no pulse. The nurse identifies the rhythm as
The Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"C"}
Ventricular fibrillation (VF) is characterized by a chaotic, rapid, and irregular electrical activity on the ECG, with no identifiable QRS complexes, P waves, or T waves. The heart quivers ineffectively, leading to no blood flow or cardiac output, which results in rapid loss of consciousness and is life-threatening.
Immediate defibrillation is required to restore a normal rhythm. A high-energy shock is delivered to the heart to reset the electrical activity, potentially allowing the heart's natural pacemaker to regain control and resume normal function.

Correct Answer is A
Explanation
A. Weighing the client provides an important baseline for monitoring fluid retention and determining the effectiveness of treatments such as diuretics. Rapid changes in weight can indicate worsening heart failure and fluid accumulation.
B. Inserting an indwelling catheter is not indicated unless there are concerns about urinary retention or output, which are not the priority here.
C. Drawing blood for chemistry studies and a CBC is important but it does not directly address the immediate concern of fluid retention and worsening heart failure.
D. Administering furosemide may be necessary depending on the client's condition, but first establishing a baseline weight is important before making further treatment decisions.
Correct Answer is B
Explanation
A. Increased risk for cardiac dysrhythmias: While hyponatremia can sometimes contribute to cardiac dysrhythmias, it's not the primary concern in this case. The main issue is fluid overload.
B. Hyponatremia, or low sodium levels, is often associated with heart failure. In this condition, the heart's reduced pumping ability leads to fluid retention, which dilutes the sodium concentration in the blood.
C. Imbalance in the sodium-potassium pump: While this can contribute to electrolyte imbalances, it's not the direct cause of hyponatremia in heart failure.
D. Acute renal failure: While heart failure can lead to acute kidney injury, hyponatremia is primarily a result of fluid overload rather than kidney dysfunction.
