The nurse is caring for a patient who has had three or more premature ventricular contractions occurring in a row on the electrocardiogram tracing. The nurse should document this as which of the following?
Ventricular tachycardia
Bigeminy
Ventricular fibrillation
Trigeminy
The Correct Answer is A
A. Three or more consecutive premature ventricular contractions (PVCs) on an ECG tracing is indicative of ventricular tachycardia, a serious arrhythmia that requires prompt intervention.
B. Bigeminy refers to a pattern of every other beat being a PVC, not necessarily three or more consecutive PVCs.
C. Ventricular fibrillation is characterized by chaotic, disorganized ventricular activity on the ECG and is not defined by the presence of consecutive PVCs.
D. Trigeminy refers to a pattern of every third beat being a PVC, not necessarily three or more consecutive PVCs.

Correct Answer is C
Explanation
A. This meal is high in fat, which may be poorly tolerated after a cholecystectomy, as it can exacerbate symptoms such as diarrhea and abdominal discomfort.
B. This meal is high in fat and may be difficult to digest after a cholecystectomy.
Whole milk can also be rich in fat, which may not be well tolerated.
C. This meal is lower in fat and includes easily digestible foods such as roast turkey and rice, which are generally well tolerated after a cholecystectomy. Gelatin dessert provides a light and refreshing option for dessert without adding excess fat.
D. This meal is high in fat, which may be poorly tolerated after a cholecystectomy, as it can exacerbate symptoms such as diarrhea and abdominal discomfort.
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.
