urinary retention; and hypertensive crisis   These discomforts can be so bothersome that some people refuse to take their medications regularly MAOIs have many drug and food interactions 12 Mood Stabilizer Medications  Lithium   Naturally occurring salt used to treat the manic phase of bipolar disorder Well-absorbed into the bloodstream and excreted faster than sodium by the kidneys •    Important for clients to balance their salt intake, fluid intake, and activity Interacts with a variety of other drugs Levels higher than 1.5 mEq/L are considered toxic Clinical improvement commonly takes as long as 3 weeks 13 Antipsychotic Medications (Slide 1 of 2)  Antipsychotics also are called major tranquilizers or neuroleptics.  Used to treat the symptoms of major mental disorders (schizophrenia, acute mania, and organic mental illnesses) and resistant bipolar (manic-depressive), paranoid, and movement disorders 14 Antipsychotic Medications (Slide 2 of 2)  Interactions  Antacids •       Hinder the absorption of antipsychotics into the bloodstream Alcohol Antianxiety medications Antihistamines Antidepressants Barbiturates Meperidine (Demerol) and morphine • Produce severe CNS depression when mixed with antipsychotics 15 Other Psychotropic Medications   SSRI antidepressants are often used to treat obsessive-compulsive disorders Examples       Clomipramine (Anafranil) Fluvoxamine (Luvox) Paroxetine (Paxil) Fluoxetine (Prozac) Sertraline (Zoloft) Stimulants are used to treat people with ADHD 16 Client Care Guidelines  For nurses and those who administer psychotherapeutic drugs:      Assess the client Coordinate care Administer the medication Monitor and evaluate responses Provide client teaching 17 Client Teaching  Every client has a right to be informed of his or her diagnosis and treatment plan   Nurses should explain in terms the client will understand Nurses should provide information in writing 18 Adverse Reactions   Health care providers, especially nurses, must constantly remain vigilant for the effects of psychotherapeutic medications Clients who are taking psychotropic drugs are at risk for developing serious problems of neuroleptic malignant syndrome and tardive dyskinesia 19 Noncompliance  Noncompliance is an informed decision made by a client not to follow a prescribed treatment program   The physician should be notified Work with your clients to find and eliminate the factors that lead to noncompliance 20 Informed Consent  Presenting clients with information about the benefits, risks, and side effects of specific treatments   Enabling them to make voluntary and knowledgeable decisions about their care Patient Self-Determination Act  States that clients have the right to accept or refuse care and cannot be pushed, coerced, or talked into following a certain course 21 Questions? 22
