What schedule of medication dosing assists older adults in adhering to a medication regimen?

What are the most common medical problems seen in older adults? (Select all that apply.)

Drug clearance is likely to be slower.

Which condition contributes to nonadherence to the medication regimen due to its lack of identifiable symptoms?

There is less creatinine overall to be filtered.

Why is it important for the nurse to obtain baseline information from a client, such as a drug profile, an accurate history of the client's usual abilities, and changes in abilities or health status?

To determine any new signs and symptoms in the client that could be related to drug therapy
