During a walk-in clinic assessment of an elderly patient with fever, which data collection step is most important to help determine a possible delirium cause?

• A. Interview the family to determine cognitive function prior to admission.
• B. Assess Mrs. Sheyer's level of hydration.
• C. Take Mrs. Sheyer's temperature.
• D. Review Mrs. Sheyer's medication profile.

Answer: (A)

Understanding delirium starts with recognizing an abrupt change from what the patient’s baseline cognition has been. In an older adult with fever, you need to know whether confusion is new or a progression of prior dementia. Interviewing the family to establish how the patient functioned cognitively before this illness gives that baseline, so you can detect an acute decline that points to delirium and helps identify possible triggers. This baseline information is what makes delirium identifiable and actionable. Fever, dehydration, and medications can all contribute, but without knowing the patient’s usual cognitive level, it’s hard to tell if there’s a new, delirium-related change or just the existing condition. Measuring temperature, assessing hydration, and reviewing medications are important pieces of the overall workup, but they don’t reveal whether an acute cognitive change has occurred as clearly as obtaining the family’s view of prior cognition. So, gathering family input about prior cognitive function provides the critical context needed to determine if delirium is present and what might be causing it.
