A nurse is reviewing the medical records for a group of clients prior to administering the clients’ medications. For which of the following clients should the nurse withhold the prescribed medication and notify the provider?

Choice A reason: Frequent urination is not a critical side effect of olanzapine, an antipsychotic. It may indicate benign issues like urinary tract infection or diabetes, but it does not warrant withholding medication. Olanzapine’s primary risks include metabolic syndrome, not urinary symptoms, requiring monitoring but not immediate cessation. Choice B reason: Muscle rigidity and tachycardia in a client taking fluoxetine, an SSRI, suggest serotonin syndrome, a life-threatening condition due to excessive serotonin. Immediate withholding of the medication and provider notification are critical to prevent complications like seizures or hyperthermia, prioritizing client safety. Choice C reason: Yawning and weight loss are common side effects of venlafaxine, an SNRI, due to its effects on serotonin and norepinephrine. These are not life-threatening and can be managed with monitoring or dose adjustment, not requiring immediate withholding or provider notification. Choice D reason: Nausea and dry mouth are expected side effects of nortriptyline, a tricyclic antidepressant, due to its anticholinergic properties. These are manageable with supportive care and do not necessitate withholding the medication, as they are not life-threatening compared to serotonin syndrome symptoms.
