A nurse is providing teaching to a client who will undergo a magnetic resonance imaging (MRI) scan. Which of the following statements is appropriate to include in the teaching?

A. Hypotension: Methamphetamines are central nervous system stimulants that typically cause hypertension and tachycardia due to increased sympathetic activity, rather than low blood pressure.

B. Weight loss: Methamphetamines suppress appetite and increase metabolism, which can lead to significant weight loss. This is a common adverse effect associated with chronic use.

C. Somnolence: Stimulant effects of methamphetamines generally cause insomnia and hyperactivity rather than excessive sleepiness. Somnolence is not a typical adverse effect.

D. Lethargy: Methamphetamine use initially produces energy and euphoria. Lethargy may occur only during withdrawal, not as a direct adverse effect of active use.

Rationale:

• Hallucinations: Auditory hallucinations, such as the client reporting listening to unseen others, are a hallmark symptom of psychosis. This indicates a break from reality and requires close psychiatric monitoring.
• Lack of sleep: Sleep deprivation is common in manic episodes due to heightened energy and decreased need for rest. Chronic sleep loss in mania can exacerbate irritability, impulsivity, and cognitive impairment.
• Pressured speech: Rapid, loud, and continuous speech is characteristic of mania. It reflects heightened energy, distractibility, and impaired judgment, often making communication difficult for caregivers.
• Excessive spending habits: Impulsive financial decisions and risky behaviors, such as giving away large sums of money, are indicative of manic episodes. These behaviors can have serious social and financial consequences.
• Disorganized thought process: Disorganized thinking can occur in both psychosis and mania. In psychosis, it may manifest as illogical or tangential thought patterns, while in mania, racing thoughts can disrupt coherent speech and planning.
