Limit testing

Alienation of family--may be aggressive
and abusive

Ion dysregulation: causes oversensitivity of
neuron to stimuli
 Alteration in transcription of messengers in
nerve cell nucleus


 Excessive Dopamine and Norepinephrine
  availability of GABA and Serotonin

A Common Diagnostic Mistake
 Diagnosing Major Depressive Disorder
when the client is in the Depressive Aspect
of Bipolar Disorder
 Giving an antidepressant can push the
client into Mania
Antipsychotics
 All Atypicals:
olanzepine: Zyprexa,
quetiapine: Seroquel, ziprasidone: Geodon,
risperidone: Risperdal and Risperdal Consta,
aripiprazole: Abilify
are FDA approved mood stabilizing agents.
 Used
alone or with other mood stabilizing
agents
 Other
antipsychotics: used prn for agitation
Lithium
Mechanism of action unknown: similarity to
action of Na /replaces Na in the body
 Slow onset: 2 weeks
 Narrow range of therapeutic level: 0.6 to 1.2
mEq/L; the optimum maintenance level is 0.8
mEq/L
 Toxic over 1.5 mEq/L
 “Normal side effects”- weight gain, fine hand
tremor, nausea, metal taste

Lithium Toxicity
Narrow therapeutic range: therapeutic
dose is close to a toxic dose.
 Mild to Moderate toxic reactions:


1.5 to 2 mEq/L
 Diarrhea
 Vomiting
 Drowsiness
 Muscular weakness
 Lack of coordination
 Dry mouth
Lithium Toxicity

Moderate to Severe reactions

2 to 3 mEq/L
 All
previous symptoms &
 Ataxia
 Tinnitus
 Blurred vision
 High urinary output (osmotic diuresis)
 Delirium
 Nystagmus
Lithium Toxicity
 Severe
reactions:  than 3 mEq/L
 All previous symptoms
 Seizures
 Organ failure
 Renal failure
 Coma

Anticonvulsants
valproic acid/divalproex: Depakote and
Depakene

Side effects: many drug interactions; CNS effects;
blood disorders ( RBC, bone marrow, WBC’s), liver
failure; toxic reactions common
Other Anticonvulsants

term tx.

clonazepam (Klonopin)
 lorazepam (Ativan)

A. Stop/hold the medication
B. Draw a lithium level, then hold the
medication

D. Draw a lithium level, keep giving the
med. until results are in.
Nursing Implications: Mood
Stabilizing Medications
What are nursing interventions for the client
a) starting on, or b) being maintained on
Lithium?
-Labs
-Other testing
