A nurse is caring for a client who consumed alcohol 2 days after taking disulfiram. The nurse should monitor the client for which of the following findings?

Choice A reason: Meningococcal vaccine starts at 11-12 years, not infancy; three doses by kindergarten is incorrect. Scientifically, this misaligns with CDC schedules, as 2-month-olds get other vaccines (e.g., DTaP), showing misunderstanding of immunization timing.

Choice B reason: No feeding restriction exists for immunizations; fasting isn’t required. Scientifically, nutrition supports immune response, and this contradicts standard practice, as feeding doesn’t affect vaccine efficacy or safety, indicating a preparation misconception.

Choice C reason: High fever for 24 hours isn’t typical; mild fever may occur but not guaranteed. Scientifically, this exaggerates normal vaccine reactions (e.g., low-grade fever), misrepresenting expected immune responses, suggesting inaccurate outcome expectations.

Choice D reason: Rotavirus vaccine is oral at 2 months, per CDC schedule, aligning with its live attenuated form. Scientifically, this reflects correct administration knowledge, as it targets gut immunity, showing the guardian understands this immunization’s delivery accurately.

Choice A reason: Echopraxia, mimicking movements, is linked to psychiatric conditions like schizophrenia, not delirium. Delirium features disordered cognition from physiological causes (e.g., infection), not motor imitation. Scientifically, this lacks relevance to delirium’s acute, fluctuating mental state driven by underlying medical issues.

Choice B reason: Aphasia, a language deficit, stems from brain damage (e.g., stroke), not delirium’s reversible cognitive disruption. Delirium affects attention and awareness, not specific linguistic skills. Scientifically, this is distinct from delirium’s diffuse, temporary confusion tied to systemic or metabolic disturbances.

Choice C reason: Acute onset of confusion defines delirium, a sudden cognitive decline from causes like infection or drugs. It’s reversible with treatment, featuring inattention and disorientation, aligning with scientific criteria as a hallmark symptom distinguishing it from chronic conditions like dementia.

Choice D reason: Inability to read relates to literacy or focal brain injury, not delirium. Delirium impairs global cognition—attention and memory—not specific skills like reading unless confusion interferes indirectly. Scientifically, this isn’t a core feature, as delirium’s impact is broader and transient.
