A patient is admitted to the hospital for a splenectomy. The nurse understands that the health-care provider prescribes an injection of vitamin K prior to surgery for which action?

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.

A. While assessment and data collection are important, the priority in the presence of a life-threatening arrhythmia is to initiate immediate interventions to address the situation.
B. The nurse should immediately inform the healthcare provider about the life- threatening arrhythmia to obtain further guidance and potential orders for intervention.
C. Vital signs are important, but they should not delay immediate action when a life- threatening arrhythmia is present.

D. Administering antiarrhythmic medication may be necessary, but the nurse should first notify the healthcare provider to obtain orders and guidance before administering any medications.
