The practical nurse (PN) applies a preparation with keratolytic properties to both legs of a client with psoriasis. Which finding indicates that the desired effect has been achieved?

Choice A reason: Recording blood pressures is relevant, as diazepam may cause hypotension, but it is less critical than respiratory monitoring. Status epilepticus requires rapid seizure control, and diazepam’s respiratory depression risk is more immediate, as it can lead to life-threatening hypoxia if not addressed promptly.

Choice B reason: Measuring urinary output monitors renal function but is not urgent in status epilepticus. Diazepam’s primary risk is respiratory depression, not renal effects. Ensuring airway and breathing stability is more critical, as seizures and the drug both threaten respiratory function, making this choice secondary.

Choice C reason: Monitoring respiratory rate and effort is critical, as diazepam, a CNS depressant, can cause respiratory depression, especially in status epilepticus, where seizures already compromise breathing. Hypoventilation risks hypoxia, potentially leading to brain damage or death, making this the most urgent intervention to ensure airway safety.

Choice D reason: Observing eye deviation may indicate ongoing seizures but is less urgent than respiratory monitoring. Diazepam controls seizures, but its side effect of respiratory depression poses an immediate threat. Ensuring adequate ventilation is the priority to prevent hypoxia during acute seizure management.

Choice A reason: Donepezil, a cholinesterase inhibitor, increases acetylcholine in the brain, enhancing cognitive function in early Alzheimer’s. It improves memory and daily functioning by supporting neuronal communication, particularly in mild-to-moderate stages, slowing symptom progression temporarily, making this the accurate description of its action.

Choice B reason: Donepezil does not target psychotic features, like hallucinations, which are managed with antipsychotics. It enhances cognitive function by boosting acetylcholine, not addressing behavioral symptoms. Psychotic features require different therapies, making this choice incorrect for donepezil’s primary role.

Choice C reason: Donepezil does not alter Alzheimer’s progressive course, as it cannot stop neuronal degeneration. It provides symptomatic relief by enhancing acetylcholine levels, temporarily improving cognition, but the disease’s underlying pathology continues, making this choice inaccurate for describing the drug’s effect.

Choice D reason: Donepezil does not cause sedation or reduce hostility. It enhances cognitive function, potentially increasing alertness. Sedation is a side effect of other drugs, like antipsychotics, not cholinesterase inhibitors, making this choice incorrect for donepezil’s therapeutic action.
