The nurse is caring for a group of clients. Which client is at highest risk for developing leukemia?

A. While atrial fibrillation with a rapid ventricular response requires attention, it is not an immediate concern unless associated with symptoms such as chest pain, shortness of breath, or hemodynamic instability.
B. A heart rate of 50 in a patient with a newly inserted permanent pacemaker may indicate bradycardia, which could be a sign of pacemaker malfunction or lead dislodgement. This patient requires immediate assessment to rule out complications.
C. While recent implantable cardioverter-defibrillator (ICD) discharge warrants evaluation, the patient is currently in normal sinus rhythm with a heart rate of 68, suggesting stability. This patient's assessment can be prioritized after the patient with the pacemaker issue is seen.
D. A heart rate of 58 in a patient with chronic atrial fibrillation on beta-blocker therapy may not be immediately concerning if the patient is asymptomatic and hemodynamically stable. This patient can be assessed after addressing the more urgent pacemaker issue.

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.
