A client with a diagnosis of an acute respiratory infection and sinus tachycardia is admitted to the hospital. The nurse should develop a plan of care for the client and include which intervention?

Sinus tachycardia is an elevated heart rate that can be exacerbated by stimulants such as caffeine. Eliminating sources of caffeine from meal trays helps manage the client's heart rate, which is critical in the context of an acute respiratory infection where cardiac demand may already be increased. Limiting fluids is not indicated unless specific fluid overload conditions are present, which is not mentioned. Measuring the pulse once per shift is insufficient for monitoring tachycardia, as more frequent assessments are needed. Short, frequent walks may be beneficial for respiratory function but do not directly address tachycardia management.
