Q

What are expected pharmacological actions of TCA’s?

A

These medications block reuptake of the monoamine neurotransmitters norepinephrine, and serotonin in the synaptic space, thereby intensifying the effects these neurotransmissions produce.

Q

What are the therapeutic uses for TCA’s in children?

A 
Depression
Autism spectrum disorder
ADHD
Panic, school phobia, separation anxiety disorder
OCD
17
Q

What are complications/ adverse effects of TCA’s?

A 
Orthostatic hypotension
Anticholinergic effects
Weight gain
Sedation 
Toxicity resulting in cholinergic blockade and cardiac toxicity AEB dysrhythmias, mental confusion, and agitation, followed by seizures and coma.
Decreased seizure threshold 
Excessive sweating ( diaphoresis)
18
Q

What are the symptoms of anticholinergic effects and how can a pt. Treat the symptoms.?

A

Dry mouth..can b relieved by chewing sugarless gum
Blurred vision…can b relieved by avoiding hazardous activities
Photophobia…can b relieved by wearing sunglasses outdoors.
Urinary hesitancy/ retention…can b relieved by void just before taking meds and drinking more fluids.
Constipation can be relieved by eating foods high in fibers
Tachycardia….participate in regular exercise

19
Q

What are contraindications and precautions to consider while taking TCA’s?

A

Use cautiously in clients who have seizure disorders, diabetes, liver and respiratory disorders, and hyperthyroidism.

20
Q

What are medication/ food interactions of TCA’s?

A

Concurrent use of monoamine oxidase inhibitors causes hypertension
Antihistamines and other cholinergic agents have additive anticholinergic effects.
TCA’s block uptake of epinephrine and norepinephrine ( direct acting sympathomimetics)in the synaptic space, leading to decreased intensity to their effects.
TCA’s inhibit uptake of ephedrine and amphetamine ( indirect acting sympathomimetics) and reduce their ability to get to the site of action in the nerve terminal, leading to decreased responses to these medications.
Alcohols, benzodiazepines, opioids and antihistamines cause additive CNS depression when used concurrently.

21
Q

What is the prototype drug of alpha2-adrenergic agonists?

A

guanfacine ( Imtuniv)

Other medications: clonidine ( Kapvay)

**Used for ADHD

22
Q

What is the expected pharmacological action of alpha 2 adrenergic agonists?

A

The action of alpha2 adrenergic agonists is not completely understood however they are known to activate presynaptic alpha2 adrenergic receptors within the brain.

Used for ADHD

23
Q

What are adverse effects of alpha2 adrenergic agonists?

A 
CNS effects( sedation, drowsiness, fatigue)
Cardiovascular effects ( hypotension, bradycardia) 
Weight gain
24
Q

What are contraindications and precautions of alpha2 adrenergic agonists?

A

Extended release clonidine is contraindicated for children less than 6yrs old.
Use cautiously in clients who have cardiac disease.

25
Q

What are medication / food interactions of alpha2 adrenergic agonists?

A

CNS depressants, including alcohol, can increase CNS effects
Antihypertensives can worsen hypotension
Foods with high fat content will increase guanfacine absorption.

26
Q

What is the prototype drug of atypical antidepressants?

A

risperidone (Risperidone)

Other medications:
olanzapine (Zyprexa)

27
Q

What is the expected pharmacological action of atypical antidepressants?

A

These antipsychotic agents work mainly by blocking serotonin and to a lesser degree, dopamine receptors for norepinephrine, histamine and acetylcholine.

28
Q

What are the therapeutic uses of atypical antipsychotic drugs?

A

Autism spectrum disorder
Conduct disorder
PTSD
Relief of psychotic manifestations

29
Q

What are complication/adverse effects of atypical antipsychotics?

A

New onset of diabetes or loss of glucose control in pt.who have diabetes
Wt. gain
Hypercholesterolemia w/ increased risk for HTN and other cardiovascular diseases.
Orthostatic hypotension
Anticholinergic effects
Agitation, dizziness, sedation, and sleep disruption
May cause mild extrapyramidal adverse effects such as tremor.

30
Q

For a pt. With an adverse effect of hypercholesterolemia with increase risk of hypertension and other cardiovascular diseases what should a nurse do?

A

Monitor cholesterol, triglycerides and blood glucose if wt gain is more than 14 kg ( 30lb)

31
Q

What are contraindications and precautions to consider when a client is taking atypical antipsychotics?

A

Use cautiously in clients who have cardiovascular disease, seizures or diabetes mellitus. Obtain baseline fasting glucose for clients who have diabetes mellitus and monitor carefully.

32
Q

What are medication/ food interactions for atypical antipsychotics?

A

Alcohol, opioids, and antihistamines cause additive CNS depressant effects.
By activating dopamine receptors, levodopa counteracts effects of antipsychotic agents
TCA’s amiodarone ( Cordarone) and clarithromycin ( Biaxin) prolong QT intervals and thus increases the risk of cardiac dysrhythmias.
Barbituates and phenytoin ( Dilantin) promote hepatic drug metabolizing enzymes, thereby decreasing drug levels of quetiapine.
Medications that inhibit CYP3A4, such as fluconazole (Diflucan) inhibit hepatic drug metabolizing enzymes

33
Q

What is a nursing administration to consider when a giving atypical antipsychotics?

A

Administer by ORAL or IM route.

risperidone is avail in an oral solution and quick dissolving tablets for ease of administration.

Olanzapine is avail in an orally disintegrating tab for ease of administration.

34
Q

A nurse is teaching the parents of a child who has a new prescription for desipramine ( Norpramin) about possible adverse effects. The nurse should instruct the parents that what adverse effect is the highest priority to report to the provider?

A

Confusion is an indication of toxicity which is greatest risk to the client.

35
Q

A nurse is teaching an adolescent client who has a new prescription for clomipramine (Anafranil) for OCD. what should the nurse teach the client in order to minimize an adverse effect of his medication?

A

Wearing sunglasses when outdoors will decrease photophobia, an anticholinergic effect associated with TCA use.

36
Q

A nurse is caring for a school age child who recently began a prescription for atomoxetine (Straterra). What possible complication should the nurse monitor with the child?

A

Liver damage is a potential complication of atomoxetine. The nurse should monitor for manifestations such as jaundice, upper abdominal tenderness, darkening of urine, and elevated liver enzymes.

37
Q

A nurse is caring for a school age child,who,has a new prescription for methylphenidate ( Concerta) to treat ADHD. What should the nurse teach the client and family about this medication?

A

Take this med orally once daily in the morning.

38
Q

A nurse is teaching a school age child and his parents about a new prescription for Lisdexamfetamine dimesylate ( Vyvanse). What is appropriate for the nurse to include in the teaching?

A

An adverse effect of this med is CNS stimulation…such as insomnia and restlessness

Monitor BP while taking this med….due to the cardiovascular effects of VyVanse.

This med raised the level of dopamine into the brain… This med works by raising the levels of norepinephrine, serotonin and dopamine into the CNS.

39
Q

What are medications for children and adolescents with mental health issues?

A

Tricyclic antidepressants
Nonbarbiturate anxiolytics
CNS stimulants
