These substances can create a powerful craving for their effects due to their ability to increase alertness, attention, and euphoria.

Rationale: The best statement explaining why the nurse should instruct the client to take prednisone (Deltasone) in the morning is that morning administration mimics the body's natural corticosteroid secretion pattern.

By taking prednisone in the morning, the client aligns the medication's peak effects with the body's natural cortisol levels, which can help reduce the risk of disrupting the body's internal rhythm and minimize potential side effects. This timing also helps achieve optimal therapeutic effects while minimizing the risk of adrenal suppression and other adverse effects associated with corticosteroid use.
