Term
3 main things that digoxin does?
Definition
1) Increases myocardial contractility
2) Change electrical conduction of the heart
3) slows heartbeat
Term
What is an example of a positive inotropic drugs
Definition
Digoxin
Term
Digoxin does what
Definition
increases force of contraction
reduces heart rate
decreases conduction
Term
Give a point concering the therapeutic window of digoxin
Definition
very small window between therapeutic and toxic
Term
Low levels of what increases digoxin toxicity ?
Definition
Pottasium levels
Term
Name 5 side effects of digoxin,
Definition
dysrhytmias, headaches, fatigue, colored vision, halo vision, flashes of light
Term
What is digoxin immune fab
Definition
for extreme toxicity,or low potassium levels, it binds to digoxin to make it normal again
Term
7 things that predispose to digoxin toxicity
Definition
Hypokalemia
Use of pacemaker
Hepatic dysfunction
Hypercalcemia
Dysrhyitmias
Renal disease
Advanced age
Term
Digoxin does what with other medication
Definition
Interacts with almost everything, so if person has other meds give at seperate times.
Term
Important Nursing Considerations for digoxin ?
Definition
Take apical pulse for one minute to check for dysrythmias (toxicity)
Serum labs: potassium levelss, ect..
If pulse under 60 too slow if over 120 not working, hold dose notify perscriber.
Weight patient
Avoid giving with high fiber foods
2.2 lbs (1kg) in a day or moer than 2 kg in a week, notify perscriber
Term
Difference between alphas and ebtas
Definition
Alphas- vascular system , betas: heart and lung receptors.
Term
Difference between B1 and B2
Definition
B1 selective only heart
B2 lungs
Term
What does cetrally acting alpha 2 agonist
Definition
stimulates adrenergic receptors, and reduces renin activity in the kidneys
Term
Explain B blockers
Definition
Reduces BP by reducing heart rate with B1
Term
Stroke volume determines what
Definition
bp
Term
Explain the dual action alpha adn beta blockers
Definition
reduction adn heart rate and vasodialiation
Term
Two examples of dual action alpha adn beta
Definition
labetalol , carvedilol
Term
what is catapres and when is it used
Definition
centrally acting alpha receptor agonist
used in critical care or reanamation
Term
Why are adrenergic drugs not used often?
Definition
High incidence of orthostatic hypotension
Term
What can ACE INHIBITORS BE COMBINED WITH
Definition
calcium chanell blockers or thiazide diuretic
Term
Ace inhibitor mechanism of action ?
Definition
Stops the enzyme conversting angiotensin 1 to 2 because 2 is a vasoconstrictor.
Term
Ace inhibitors always end in what and give two examples?
Definition
pril, enalapril
Term
Ace inhibitors cause what anoying adverse effect
Definition
dry cought
Term
why do we like angiotensis 2 receptor blockers
Definition
because they do not cause a dry cough
Term
Mechanism of action of angiotensis 2 receptor blockers
Definition
angiotensis can convert from 1 to 2 but block the receptors that recieve 2.
Term
Mechanism of calcium chanel blockers
Definition
causes smooth musccle relaxation by blocking the binding of calcium to its receptos, preventing muscle contraction which makes blood flow easier = lower bp
Term
What do diuretics do overall ?
Definition
Decreases workload of heart and decreases blood presure
Term
What are the most comonly used diuretics?
Definition
Thiazide diuretics
Term
Mechanism of vasodialators
Definition
directly relaxes arteiolar and venous smooth muscle = decrease systemic vascular response, decreased afterload, and peripheral vasodilation.
Term
Nipride, (sodium nitroprusside) is reserved for management of hypertensive emergency. true or false
Definition
true
Term
Before giving vasodialators the nurse should:
Definition
head to toe assesment to check for vasucal edema, contraiditcions, not to miss a dose, keep journal of bp checks, not to stop drugs cause it can cause a rebound hypertensive crisis, encourage change of lifestyle and to change positions slowly because of hypotension, hot baths and ect can cause more vasdialation leading to fainting, mointor therapeutic effect
Term
Diabetes type 1 vs diabetes type 2
Definition
Type 1: lack of insulin
Type 2: insulin resistance
Term
What is diabetic ketoacidosis?
Definition
Too much blood sugar
Term
Steps to type 2 diabetes treatment
Definition
1) lifestyle changes
2) oral meds

Definition
10 to 15 minute onset, give right when they eat sub q, examples: novorapid, humalog
Term
Explain short acting insulins...
Definition
Onset 30-60 minutes , give before eating,
Humulin R, Novolin ge Toronto
Term
Explain intermediate acting ...
Definition
cloudy appearance, 12-18 hours, onset 1-3 hours, NPH,
Term

Definition
last up to 24 hours, clear, onset 90 minutes, examples: lantus, levemir.
Term
When using sliding scale, at bedtime how much do you give ?
Definition
Half the dose
Term
example of sulfonylureas
Definition
glyburide: can cause hypoglycemia , secreating o beta cells of the pancreas causing increased insulin levels
Term
Name an example of menlintinides:
Definition
Gluconorm (repaglinide): cause hypo
Term
example of bigaunides:
Definition
metformin(glucophage): decrease production of glucose not insulin secreation so does not cause hypo
Term
example of thiazolidinediones:
Definition
avandia-rosiglitazone: decreases insulin resistance wont cause hypo
Term
When drawing up two different kinds of insulins:
Definition
Clear to cloudy, regular or rapid first.
Term
Bronchodialators during what?
Definition
acute phase of asthma attack example: ventolin (salbutamol`)
Term
Mechanism of antocholinergics:
Definition
binds to ach to prevent constriction and narrowing of airways.
Term

Definition
Spiriva, atrovent
Term
Antileukoptrienes mechanism of action:
Definition
blocking leukotrienes = prevent smooth muscle contraction example: singulair ,accolate

dont use for acute asthma attacks: this is an antiinflamatory, example: flovent
