Use of levodopa-carbidopa? - ANSWER-Treatment of Parkinson's and parkinsonisms

Therapeutic effects of levodopa-carbidopa? - ANSWER-Improvement in mobility, balance, posture, gait, speech, handwriting, and self-care ability; elimination of drooling and seborrhea; mood elevation

Contraindications for levodopa-carbidopa? - ANSWER-Narrow-angle glaucoma; suspicious skin lesions or history of melanoma; 14 days within MAOI administration

Adverse effects of levodopa-carbidopa? - ANSWER-Headache and anxiety Older patients: hallucinations, dementia, drowsiness 1 / 4

Most severe: depression w/ SI

CV: ectopic beats, anginal pain, hypotension, dyspnea, widened QRS,

tachycardia, palpitations, vasoconstriction, bradycardia, orthostatic hypotension Anorexia, bruxism (clenching/grinding of teeth), n/v Piloerection (goosebumps), azotemia (high levels of nitrogen-containing compounds), gangrene

QSEN for levodopa-carbidopa? - ANSWER-Admin at correct time is critical for optimal therapeutic effects

Patient teaching for levodopa-carbidopa? - ANSWER-Avoid alcohol Don't take vitamin B6 group Understand adverse effects like drowsiness, dizziness, and orthostatic hypotension Take with food, but not high-protein meals Report fainting, light-headedness, irregular HR, uncontrolled facial movements, urinary retention, n/v Notify HCP of static gait, altered mobility, and "pill rolling"

What do isotonic crystalloids do? - ANSWER-Expand circulating IV fluid (plasma) without causing a fluid shift between compartments for pts with dehydration and LOW BP

Used to relieve cellular edema, especially cerebral edema - ANSWER- Hypertonic

Indicated for patients with hypernatremia and cellular dehydration; dehydration with normal BP - ANSWER-hypotonic

What class is norepinephrine? - ANSWER-adrenergic drug

What is the action of NE? - ANSWER-predominant alpha-receptor agonist effects, and results in potent peripheral arterial vasoconstriction - -> increases BP more than HR, force of contraction, or cardiac output

Use of NE? - ANSWER-Cardiogenic and septic shock; severe hypotension and shock that persists after adequate fluid volume replacement (FIRST CHOICE)

Why is NE not good for prolonged use? - ANSWER-Reduced renal blood flow

What are the therapeutic effects to monitor for with NE? - ANSWER-

Adequate tissue perfusion including:

MAP of at least 65 HR less than 10 Unlabored breathing 3 / 4

Serum lactate and ABG WDL Urine output greater than 30 mL/hr normal mentation O2 greater than 90 No dyspnea Warm, dry skin w/ no sign of diminished perfusion Lab values WDL

Contraindications for NE? - ANSWER-Cardiac dysrhythmias; angina pectoris; HTN; hyperthyroidism; cerebrovascular disease; narrow-angle glaucoma; hypersensitivity

Adverse effects of NE? - ANSWER-Diminished renal perfusion and urine output (vasopressor action) Decreased perfusion to liver (liver damage) Irritable cardiac dysrhythmias (beta1 activity) Increase in myocardial O2 requirement (beta1 activity) hyerglycemia, hypokalemia, hypophosphatemia (beta1 activity) severe HTN and reflex bradycardia limb ischemia due to profound vasoconstriction extravasation
