The therapeutic range for lithium is generally considered to be between 0.5-1.2 mEq/L. Some individuals may be susceptible to levels up to 1.5 mEg/L, however it is encouraged to maintain levels below 1.5 to prevent Lithium toxicity. Levels above this range may cause signs of toxicity, such as vomiting, diarrhea, confusion, and uncontrolled shaking/tremors, while levels below this range may be ineffective in treating bipolar disorder.
When a client exhibits signs of lithium toxicity, the immediate action is to hold the dose of medication and notify the healthcare provider. Activated charcoal is not typically used to treat lithium toxicity, and administering more lithium would worsen the condition. Encouraging fluids may help, but the priority is to stop further lithium intake.
If a client on Clozapine therapy presents with symptoms of agranulocytosis, which include fever, sore throat, and malaise, the immediate action is to discontinue Clozapine and notify the healthcare provider. Agranulocytosis is a severe and potentially life-threatening side effect of Clozapine.
False - High levels of dopamine in the brain worsen mania and psychosis. Most antipsychotics, especially the older ones, block the effects of dopamine in certain parts of the brain to bring about their antipsychotic effect. Other mechanisms are also involved in the antipsychotic effect of these medications)
This statement indicates a need for further education because if a client suspects the development of NMS symptoms (such as muscle stiffness and high fever), they should discontinue the medication immediately and seek medical attention. Continuing the medication in the presence of these symptoms can worsen the condition.
MAOIs can interact with foods high in tyramine, potentially causing a hypertensive crisis. Patients on MAOIs should avoid these foods.
The nurse would prepare to administer an antipsychotic medication such as Haldol to a client experiencing amphetamine psychosis to decrease agitation & psychotic symptoms, including delusions, hallucinations & cognitive impairment. Haloperidol is a first-generation (typical) antipsychotic medication that is used widely around the world
Opiate withdrawal is characterized by a range of physical and psychological symptoms, including diarrhea, yawning, dilated pupils (not pupillary constriction), and other signs of sympathetic nervous system activation. Slurred speech and bradycardia are not typical symptoms of opiate withdrawal.
Weight gain is a common side effect of some atypical antipsychotic medications. Collaborating with the healthcare provider to explore alternative medications with fewer metabolic side effects is a reasonable approach.
Serotonin syndrome is characterized by a constellation of symptoms, which may include profuse sweating, hyperthermia, tachycardia (not bradycardia), and increased blood pressure (not decreased blood pressure). Increased appetite is not typically associated with serotonin syndrome.
Benzodiazepines are used in alcohol withdrawal to enhance the inhibitory effects of GABA, which helps reduce the symptoms of withdrawal, such as anxiety and seizures. Options A, B, and D do not accurately describe the mechanism of action of benzodiazepines in managing alcohol withdrawal.
This response provides an accurate distinction between TCAs and SSRIs in terms of their primary neurotransmitter effects. TCAs primarily affect serotonin and norepinephrine levels, while SSRIs specifically target serotonin. Options A, B, and D contain inaccurate statements about the neurotransmitters targeted by these medications.
This response provides an accurate distinction between benzodiazepines and barbiturates regarding side effects. Benzodiazepines are generally associated with fewer issues related to coordination and memory compared to barbiturates, which can cause significant impairment in these areas. The other options are not accurate descriptions of the side effects associated with these medication classes.
The common side effects associated Antiparkinsonian drugs are nausea, dry mouth, dizziness, and constipation)
Diuretics work by promoting the removal of excess fluid and sodium from the body through the urine. This reduces the volume of blood and preload on the heart, helping to alleviate symptoms
of heart failure. Options A, B, and C do not accurately describe the primary mechanism of action of diuretics in heart failure.
An optimal therapeutic response to thyroxine replacement therapy for hypothyroidism includes improved energy levels and resolution of fatigue. Bradycardia (slow heart rate), weight gain, and cold intolerance are symptoms of hypothyroidism and would be signs of an inadequate therapeutic response.
Beta-blockers can lower blood pressure, which can lead to hypotension and dizziness. This is an important side effect to monitor in patients taking these medications.
Metformin primarily works by decreasing insulin resistance in the body, allowing insulin to be more effective in lowering blood sugar levels. It does not stimulate the pancreas to produce more insulin, and it does not promote glucose release from the liver. Understanding the mechanism of action of metformin is essential for nurses caring for patients with diabetes.
