A nurse in a surgical clinic is providing teaching to a client who is scheduled for a modified radical mastectomy. Which of the following statements by the client indicates an understanding of the teaching?

A. Seizure disorder: A seizure disorder does not directly affect the use of metformin. While some medications used to manage seizures may have interactions, metformin itself is not contraindicated in clients with a history of seizures, and it can generally be used safely with proper monitoring.

B. Renal insufficiency: Metformin is contraindicated in clients with renal insufficiency because impaired kidney function can lead to accumulation of the drug, increasing the risk of lactic acidosis, a rare but potentially life-threatening complication. Baseline and ongoing assessment of renal function, such as serum creatinine and estimated glomerular filtration rate (eGFR), is essential before starting therapy.

C. Polycystic ovary syndrome: Metformin is actually commonly used in clients with polycystic ovary syndrome to improve insulin sensitivity and support ovulation. This condition is not a contraindication, and metformin may provide therapeutic benefits beyond glucose control.

D. Gluten intolerance: Gluten intolerance has no impact on metformin use. Metformin does not contain gluten and does not interfere with gluten-related conditions, so it can be safely prescribed in clients with gluten intolerance.

Rationale:

• Pressured speech: The client demonstrates rapid, loud, and nonstop speech, characteristic of mania. Pressured speech reflects heightened energy, distractibility, and decreased need for rest, all typical of a manic episode. It is not a primary symptom of psychosis, although severe psychotic agitation can sometimes alter speech.

• Hallucinations: The client reports seeing a person who is not present and interacting with them, which is a hallmark of psychosis. These perceptual disturbances indicate impaired reality testing. Hallucinations are less common in purely manic states unless mania is accompanied by psychotic features. Here, the client’s persistent visual hallucinations support a diagnosis of psychosis.

• Disorganized thought process: The client exhibits disorganized and tangential speech, reflecting difficulty organizing thoughts. Disorganization is characteristic of psychotic disorders due to impaired reality testing and cognitive processing. It can also appear in mania, particularly when the client exhibits distractibility, racing thoughts, and pressured speech.

• Lack of sleep: The client has gone at least 2 days without sleeping, a classic sign of mania. Decreased need for sleep with preserved energy is typical in manic episodes. Sleep deprivation alone does not indicate psychosis unless accompanied by hallucinations or delusions.

• Excessive spending habits: The client exhibits impulsive financial behavior, giving away large sums of money and overspending. This risk-taking and poor judgment are hallmark features of mania. Such behaviors are less commonly associated with psychosis unless delusions drive them.
