Methylphenidate (Methylin, Ritalin) Adderall Class: stimulants
• •Uses: Methylphenidate is an example of a CNS stimulant that is often used to treat ADHD. CNS stimulants are Schedule II controlled substances and have a high potential for abuse and dependence. •Mode of Action •Methylphenidate stimulates the brain and acts similar to amphetamines. Methylphenidate is thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron •Adverse/Side Effects •Immediately report signs and symptoms of abuse, cardiac or peripheral vascular complications, and priapism •Report mania or psychotic episodes •Common side effects: headache, insomnia, upper abdominal pain, decreased appetite, and anorexia •Gynecomastia •Teaching/Education •Black Box Warning: High abuse potential •Patients should avoid alcohol •Monitor BP and HR; can increase BP •Monitor growth and weight in children; causes growth suppression •Monitor for signs of abuse •Contraindicated with MAOIs or use of an MAOI within the preceding 14 days
tranylcypromine (Parnate), phenelzine (Nardil,) isocarboxazid (Marplan) Class: monoamine oxidase inhibitors (MAOIs)
•1st generation antidepressant and can be used in Parkinson's disease. •Significant disadvantage of MAOIs is their potential to cause a hypertensive crisis when taken with stimulating medications or foods containing tyramine. •Mode of Action •MAO is an enzyme that inactivates norepinephrine, dopamine, epinephrine, and serotonin. By inhibiting MAO, the levels of these transmitters rise. •Adverse/Side Effect •Black Box Warning: monitor for hypertensive crisis & increased suicidal ideation •S/E: dizziness, drowsiness, weakness/fatigue, loss of appetite, N/V, irritability/nervousness •Administration •Do NOT stop abruptly; take medication as prescribed. •Interact with MANY other medications. •Teaching •Limit intake of tyramine-rich foods (cheese, alcohol, banana, avocados, red wine, salami/pepperoni, & chocolate), tyramine can lead to a hypertensive crisis for up to 2 weeks after therapy. •Discontinue at the 1st sign of hepatic function (jaundice) •Discontinue 2 weeks before starting any other meds.
Schizophrenia
•Affects people from all walks of life & usually appears between the ages of 15 and 30. Not everyone will experience the same symptoms, but many symptoms are common such as withdrawing, hearing voices, talking to oneself, seeing things that are not there, neglecting personal hygiene, and showing low energy •Positive symptoms: include altered perceptions (e.g., changes in vision, hearing, smell, touch, and taste), abnormal thinking, and odd behaviors. •Negative symptoms: include loss of motivation, disinterest or lack of enjoyment in daily activities, social withdrawal, difficulty showing emotions, and difficulty functioning normally. •Cognitive symptoms include problems in attention, concentration, and memory.
Aspirin
•Contraindicated if the patient has a bleeding disorder such as hemophilia or a recent history of bleeding in the stomach or intestine. •Black Box Warning: •Children or teenagers should not take aspirin to treat chickenpox or flu-like symptoms because of the risk of Reye's Syndrome. •Teaching/Education •Patients should avoid concurrent use of alcohol while taking medication to avoid gastric irritation. •Report tinnitus, unusual bleeding, or fever lasting greater than 3 days to the healthcare provider (toxic effect of aspirin). •Take with a full glass of water and sit upright for 15-30 minutes after administration •Take with food if the patient reports that aspirin upsets their stomach •Do not crush, chew, break, or open an enteric-coated or delayed-release pill; it should be swallowed whole •The chewable tablet form must be chewed before swallowing •Should be stopped 7 days prior to surgery due to the risk of postoperative bleeding
Symptoms of hypertensive crisis
•Severe hypertension with evidence of organ dysfunction •Blood pressure >180/120 •Palpitations •Neck stiffness or soreness •Nausea/vomiting •Sweating •Dilated pupils •Photophobia •SOB •Confusion •Tachycardia or bradycardia •Seizures •Intracranial bleeding (due to elevated BP)
What are the signs and symptoms of ADHD?
•Hyperactivity •Inability to concentrate •Difficulty with self-control •Lack of emotional control
Nursing Process for Pain Management- Evaluation
•It is important to always evaluate the patient's response to the medication. •With analgesic medications, the nurse should assess for the decrease in pain 30 minutes after IV administration and 60 minutes after oral medication. •If the patient's pain level is not acceptable, the nurse should investigate alternate treatment modalities. •The nurse is a patients' advocate, the healthcare provider may have to be informed if the patient's pain is not being controlled by analgesics. •One of the adverse effects of opioid analgesics is respiratory depression. The nurse should evaluate the respiratory rate, pulse oximetry, and blood pressure after administration of the medication. •Other common side effects of opioid analgesic medications are constipation or nausea.
How is bipolar treated?
•Medications, psychotherapy, or a combination of the two. (antidepressants, and pscychotherapies such as talk therapy) •Electroconvulsive therapy (ECT)
Parkinson's Disease
•Parkinson's disease is a progressive disease of the nervous system that impairs one's ability to move. •The typical onset for Parkinson's disease is middle to later stages of life. •Parkinson's disease is believed to be related to an imbalance of dopamine and acetylcholine and a deficiency of dopamine in certain areas of the brain, so drug therapies are aimed at restoring the balance of dopamine and/or acetylcholine. •Drug therapy does not cure the disease, but is used to slow the progression of symptoms. •Common medications used to treat Parkinson's disease are carbidopa/levodopa, selegiline, and amantadine.
Classes of seizures:
•Partial seizures have focal onset on one side of the brain. •They are further classified into simple, complex, or secondarily generalized: simple partial, complex partial, and tonic-clonic seizures. •Generalized seizures have bilateral onset on both sides of the brain and are typified by petit mal seizures. •Status epilepticus is a state of repeated or continuous seizures. •It is often defined operationally as a single seizure lasting more than 20 minutes or repeated seizures without recovery of consciousness. •Prolonged status epilepticus leads to irreversible brain injury and has a very high rate of mortality.
Nursing Process for Pain Management- Implementation
•Perform the five rights (right patient, medication, dose, route, and time) and to check for allergies prior to administration. •Prior to administration, it is important to consider the best route of administration for this patient at this particular time. •For example, if the patient is nauseated and vomiting, then an oral route may not be effective. An antiemetic may have to be administered prior to pain medication. •When administering opioid medications, it is important to remember that these medications are controlled substances with special regulations regarding storage, auditing counts, and disposal or wasting of medication •A general rule of thumb when administering analgesics is to use the least invasive medication that is anticipated to treat the level of pain reported by the patient.
Signs and symptoms of depression
•Persistent sad, anxious, or "empty" mood •Feeling of hopelessness, or pessimism •Irritability •Feelings of guilt, worthlessness, or helplessness •Loss of interest or pleasure in hobbies, & activities •Decreased energy or fatigue •Moving or talking more slowly •Feeling restless or having trouble sitting still •Difficulty concentrating, remembering, or making decisions •Difficulty sleeping, early-morning awakening, or oversleeping •Appetite and/or weight changes •Thoughts of death or suicide, or suicide attempts •Aches or pains, headaches, cramps, or digestive problems
