Q

What health teaching is required for a patient who says “I’ve been on xanax for 3m and i want to be off my medication now, i’m better.”

A
  • Avoid alcohol, driving, operating machinery, grapefruit and OTC medications (especially if they cause sedation (antihistamines), take with food
  • As the nurse you would monitor for anxiety, etc.(ask and look)
  • Cannot directly stop taking medication (long term use causes dependance so if they stop immediately they will have withdrawal symptoms; must taper dose down)
  • sometimes have N&V, seizures, panic attacks, etc

25
What is the biogenic amine theory of depression?
Depression results from a deficiency of norepinephrine (NE), dopamine, or serotonin (5HT); which are all biogenic amines :) - Monoamine oxidase (MAO) may break them down to be recycled or restored in the neuron - Rapid fire of the neurons may lead to their depletion - The number or sensitivity of postsynaptic receptors may increase, depleting neurotransmitter levels

Effects directly related to the lithium serum level - Less than 1.5 – lethargy, slurred speech, muscle weakness, nausea, vomiting - Levels 1.5-2 – above reactions plus ECG changes - Levels 2-2.5 – ataxia, clonic movements, hyperreflexia, seizures - Levels >2.5 Complex multiorgan toxicity, significant risk of death
111
What assessment would the nurse make for patient taking lithium?
- Start to monitor at about 8h and continue to monitor until you find an appropriate dose - Once they go home they need to have their lithium checked every 3m. - Teach about when to go to the hospital - Dietary sodium remain about the same (too little causes too much lithium and too much causes too little lithium) - Need to have lots of water (especially in hot weather, etc) - Avoid caffeine however do not make big changes
