A nurse is assisting with the care of a client. Exhibits The nurse is reinforcing teaching for the client and their family about potential adverse effects of the client's prescribed medications. For each potential adverse effect, click to specify if the effect is. consistent with agranulocytosis, neuroleptic malignant syndrome, or. serotonin syndrome. Each finding may support more than 1 disease process.

Condition Definition Causes Symptoms Treatment Agranulocytosis A severe and potentially life-threatening reduction in the number of white blood cells (neutrophils) that fight infection. Can be caused by some antipsychotic medications, such as clozapine, olanzapine, and quetiapine. Sore throat, fever, chills, mouth ulcers, infections, bleeding, and fatigue. Discontinuation of the offending medication, antibiotics, antifungals, and granulocyte colony-stimulating factor (G-CSF) injections to stimulate the bone marrow to produce more white blood cells. Neuroleptic Malignant Syndrome (NMS) A rare but serious reaction to antipsychotic medications, especially the older ones, such as haloperidol, fluphenazine, and chlorpromazine. Can be triggered by high doses, rapid dose changes, or switching of antipsychotic medications. High fever, muscle rigidity, altered mental status, autonomic instability (blood pressure changes, tachycardia, sweating, etc.), and elevated creatine kinase levels. Discontinuation of the offending medication, supportive care, cooling measures, hydration, and medications such as dantrolene, bromocriptine, or amantadine to counteract the effects of dopamine blockade. Serotonin Syndrome A potentially life-threatening condition caused by excessive levels of serotonin in the brain. Can be caused by taking too much of a serotonin-enhancing medication, such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), or other drugs that affect serotonin levels, such as tramadol, linezolid, or St. John’s wort. Can also be caused by combining two or more serotonin-enhancing medications. Agitation, confusion, disorientation, anxiety, hallucinations, muscle spasms, tremors, shivering, hyperreflexia, incoordination, diarrhea, nausea, vomiting, blood pressure changes, tachycardia, and hyperthermia. Discontinuation of the offending medication(s), supportive care, hydration, and medications such as benzodiazepines, cyproheptadine, or serotonin antagonists to reduce serotonin levels.
