An 84-year-old admitted with pneumonia is acutely confused, fluctuating attention, with a positive CAM screen. He is calm but inattentive (hypoactive delirium). Which intervention is the priority?
1Give oral haloperidol 0.5 mg every 8 hours for 48 hours to manage hypoactive delirium and prevent further cognitive decline.
2Apply bilateral soft wrist restraints to the bed to protect the patient from pulling out the Foley catheter during confusion.
3Schedule an emergent brain MRI with contrast as the initial diagnostic step to evaluate for structural brain lesions causing hypoactive delirium.
4Identify and treat reversible causes — review and deprescribe anticholinergic medications, treat the pneumonia, remove the unnecessary Foley✓ Correct answer
Explanation
Delirium management is FOUNDATIONAL nonpharmacologic with treatment of reversible causes: deprescribe high-risk medications (anticholinergics like diphenhydramine and oxybutynin, sedatives like zolpidem, dopamine antagonists like reglan), treat infection (pneumonia here), remove unnecessary tethers (Foley contributes to delirium), reorient, mobilize, sleep hygiene. Antipsychotics are REJECTED as routine; reserved for severe agitation harming self/staff with non-pharm failure (and only short term, low dose) — and AVOIDED in pure hypoactive delirium. Restraints worsen delirium. MRI is for focal findings, not initial step in delirium with clear medical precipitant.
Hypoactive delirium has higher mortality and is missed often. Use validated tools (CAM, CAM-ICU, 4AT) for screening. Ages 65+ at hospital admission warrant routine screening.
Reglan, oxybutynin, zolpidem, diphenhydramine on home med list. Sleep poor. Foley in place.
