A client with a history of schizophrenia, and drug and alcohol abuse is admitted to the hospital for hepatitis. The nurse should contact the healthcare provider before implementing which prescription?

Choice A reason: Monitoring serum potassium is relevant, as lisinopril can cause hyperkalemia by reducing aldosterone, impairing potassium excretion. Skin turgor, however, assesses hydration, not ACE inhibitor effects. Blood pressure monitoring is more critical, as lisinopril lowers blood pressure via vasodilation, risking hypotension and falls, especially in elderly clients.

Choice B reason: Eosinophil count and constipation are unrelated to lisinopril’s effects. Elevated eosinophils may suggest allergies, but this is rare with ACE inhibitors. Constipation is not a common side effect. Lisinopril’s primary action is renin-angiotensin inhibition, making blood pressure and fall risk monitoring more urgent to prevent hypotensive complications.

Choice C reason: Lisinopril reduces angiotensin II, promoting vasodilation and lowering blood pressure. Monitoring blood pressure detects hypotension, which increases fall risk, particularly in older adults, due to dizziness or orthostatic changes. This directly assesses the drug’s cardiovascular effects, ensuring safety by preventing falls or syncope, making it the priority assessment.

Choice D reason: Heart rate and nausea are not primary lisinopril concerns. Tachycardia may occur secondary to hypotension, and nausea is rare. The drug’s main effect is blood pressure reduction via ACE inhibition, necessitating monitoring for hypotension and fall risk to ensure patient safety, as these are more immediate and significant pharmacological effects.

Choice A reason: The client’s belief in a chip in his head indicates paranoid ideation, a disturbed thought process in schizophrenia, driven by dopamine dysregulation in the mesolimbic pathway. This nursing problem targets altered reality perception, guiding antipsychotic therapy to reduce delusions, addressing the core cognitive disturbance observed.

Choice B reason: Disturbed sensory perception implies hallucinations, not delusions. The chip belief is a paranoid delusion, not a sensory issue or grandiose belief. Schizophrenia involves cognitive distortions, and “disturbed thought process” better addresses the paranoid ideation, focusing on the neurobiological basis of delusional thinking over sensory misperceptions.

Choice C reason: Impaired verbal communication is inaccurate, as the client is alert and oriented with coherent, though tangential, speech. The chip delusion reflects a thought disorder, not communication deficit. Schizophrenia’s cognitive symptoms prioritize addressing thought processes, driven by neurotransmitter imbalances, over verbal expression issues.

Choice D reason: Impaired social interaction may result from paranoid delusions but is secondary. The primary issue is the disturbed thought process causing the chip delusion, rooted in dopamine dysregulation. Addressing the delusion directly with antipsychotics is more specific, as social issues stem from this core cognitive disturbance.
