Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity, known as visual disturbances. This finding indicates an adverse effect of digoxin and should be reported immediately to the healthcare provider. Monitoring for visual changes is crucial as it can progress to more severe toxicity, leading to life-threatening dysrhythmias or other complications. Apical pulse, serum potassium level, and blood pressure are important assessments when administering digoxin, but the presence of visual disturbances, such as seeing halos around lights, takes precedence due to its direct association with digoxin toxicity. Changes in these other parameters should also be noted and addressed, but they are not the priority when compared to a symptom directly linked to potential toxicity.
