1. An infusion pump configured to provide one or more context cues to a user while the user programs the infusion pump to deliver an infusion therapy, the infusion pump comprising:
a processor; and
a memory in communication with the processor and configured to store instructions that when executed by the processor cause the execution of a keypad sequence monitor configured to:
receive one or more context parameters, the context parameters corresponding to a drug selection, a drug concentration selection, or a clinical care area in which a fluid is to be infused;
determine lower and upper soft limit values and lower and upper hard limit values corresponding to the context parameters, wherein a valid treatment parameter range associated with a treatment parameter corresponds to a range of values between the lower and upper soft limit values;
receive a user input;
update a sequence value based upon the user input;
determine that the sequence value is outside of the valid treatment parameter range;
determine that an updated context parameter different from the received context parameters is associated with updated lower and upper soft limit values that define an updated valid treatment parameter range for the treatment parameter that includes the sequence value; and
provide for display one or more context cues corresponding to the updated context parameter.
