A nurse is caring for a client who has bipolar disorder and a new prescription for valproate. Which of the following instructions should the nurse give the client about the use of this medication?

A. Bleeding:

Explanation: Bleeding is not a common adverse effect of haloperidol, which is an antipsychotic medication used to treat conditions like schizophrenia. Haloperidol primarily works on the central nervous system and is not known to directly cause bleeding issues.

B. Cataracts:

Explanation: Cataracts are not a common adverse effect of haloperidol either. While long-term use of some antipsychotic medications can lead to metabolic and endocrine disturbances, which might indirectly impact eye health, cataracts are not a direct and immediate concern with haloperidol use.

C. Dysrhythmias:

Explanation: Correct Answer. Haloperidol has the potential to cause cardiac-related adverse effects, including dysrhythmias (irregular heart rhythms). This is a particular concern in individuals who are predisposed to heart conditions or have other risk factors. The medication can prolong the QT interval, which is a measure of the time it takes for the heart's electrical system to recharge between beats. Prolonged QT interval can lead to serious and potentially life-threatening arrhythmias.

D. Pancreatitis:

Explanation: Pancreatitis is not a common adverse effect of haloperidol. Pancreatitis typically involves inflammation of the pancreas and can be caused by various factors such as gallstones, alcohol consumption, and certain medications. Haloperidol is not known to directly cause inflammation of the pancreas.

A. The client responds to questions with disorganized speech:

Disorganized speech is a hallmark of acute mania, often reflecting racing thoughts, pressured speech, and difficulty staying on topic.

B. The client reports that voices are telling him to write a novel:

Reporting that voices are telling the client to write a novel suggests auditory hallucinations, which can occur in various psychiatric conditions, not specifically indicative of acute mania.

C. The client's spouse reports that the client has recently gained weight:

Weight gain is not a typical hallmark of acute mania. In fact, during manic episodes, individuals might experience decreased appetite and sleep, leading to potential weight loss.

D. The client is dressed in all black:

Dressing in all black is not a specific sign of acute mania. While changes in clothing choices or appearance can sometimes be associated with mood changes, this finding alone is not indicative of acute mania.
