Rationale 1: The properties of a medication will determine how often it must be given to keep the drug at a therapeutic level in the body.
Rationale 2: Some medications are administered at certain times of day to improve effectiveness or decrease adverse effects.
Rationale 3: Some medications are taken to prevent or to cause an effect. For example, insulin should be given 30 minutes prior to eating to promote glucose usage.
Rationale 4: If the drug does not have a characteristic that relies on a certain event to take place, then the drug can be given at the convenience of patient and/or nurse.
Rationale 5: While most hospitals do have specific times of day (agency protocol) when medications are administered, this is not a principle that determines any specific dosing schedule.
