Providing care for pediatric and geriatric patients presents unique challenges and requires specialized knowledge. These “special populations” are not simply small or large adults; their physiology dictates distinct approaches to pharmacotherapy. For PharmD students, mastering the nuances of age-related pharmacokinetics, pharmacodynamics, appropriate dosing, and communication is fundamental to ensuring medication safety and efficacy. This quiz will test your understanding of the key principles involved in managing the medication needs of the youngest and oldest patients.
