A client with severe and persistent mental illness has been taking antipsychotic medication for 20 years. The nurse observes during a therapy session that the client's behavior includes repetitive movements of the mouth and tongue, facial grimacing, and rocking back and forth. Which action will the nurse take to address these findings?

A. Cognitive: Cognitive symptoms of schizophrenia include impairments in memory, attention, executive functioning, and problem-solving. Echolalia does not represent a cognitive deficit but rather an abnormal speech pattern tied to psychotic features.

B. Positive: Echolalia, the repetition of words or phrases spoken by another, is considered a positive symptom. Positive symptoms add abnormal experiences or behaviors, such as hallucinations, delusions, and disorganized speech, making echolalia fit into this category.

C. Hallucination: Hallucinations involve false sensory perceptions such as hearing, seeing, or feeling things that are not present. Echolalia is not a sensory distortion but a speech pattern disturbance, so it does not fall into the hallucination category.

D. Negative: Negative symptoms include diminished emotional expression, alogia, avolition, and social withdrawal. Echolalia does not reflect a reduction or absence of normal behavior but rather the presence of an additional abnormal behavior.

A. Compensated metabolic acidosis with hypoxemia: Metabolic acidosis would show a low pH with low HCO₃⁻, but here the bicarbonate is elevated (31), indicating renal compensation rather than a metabolic cause.

B. Partially compensated metabolic alkalosis: Metabolic alkalosis is characterized by elevated pH and high HCO₃⁻. In this case, the pH is low (7.33), which rules out alkalosis as the primary problem.

C. Partially compensated respiratory acidosis with hypoxemia: The pH is slightly acidic (7.33), PaCO₂ is elevated (60), and HCO₃⁻ is also elevated (31), showing renal compensation. Because the pH has not returned to normal, it is only partial compensation. PaO₂ of 75 and SaO₂ of 91% indicate mild hypoxemia.

D. Fully compensated respiratory acidosis: Full compensation occurs when the pH returns to normal. Since the pH is still below 7.35, the acidosis remains only partially compensated.
