Good nurses need to . . . know pharmacology!

Drugs can block a normal body process: inhibitors, antagonists, and blockers

Some enhance a normal function. These are called agonists.

Metabolism by the liver: Caution with patients with cirrhosis Check liver enzymes and the doses - They may need to be decreased.

Kidneys are the organs of excretion for most medications: If patients have poor kidney function . . . Look out for toxicity!

5 Rights of Drug administration: Right Drug, route, patient, time, and dosage.

Know your patient allergies. ALWAYS ask for name and ID.

Drug action may take place on cells & tissues connecting target receptors.

Drugs can bind to enzymes and hold them hostage preventing target cells from enzyme action.

Drugs can jump into metabolic process causing cell wall destruction,

Interruption and chaos is created resulting in defective cells or cell death.

Antihypertensive medications: decrease fluids, block constriction, dilate vessels.

Depending on the patient’s presentation

Combinations of drugs include: Thiazides, ARBs, and ‘Prils

Alpha 2 (blockers): clonidine, guanfacine, & methyldopa

Terazosin, Cardura, Minipress – block alpha 1 reducing PVR & Pressure.

Opiods treat Post-Operative and unrelenting pain!

Demerol, Fentanyl, Morphine,Codeine - are players in this game.

Side effects are: Constipation, And a decreased respiratory rate, Nausea and Vomiting, Urine retention, Altered mental state, Psychological Dependency, Overdose & Drug toxicity Oxycodone, Hydromorphone

Reverse side effects with Narcan an opiod-antagonist

Meds used to treat CAD: Relax vascular smooth muscle: Decrease BP

Nitrates can be given different ways: ointment, tablets, transdermal, or sprays.

Sublingual take a dose Q5 minutes (times 3), Assess pain levels, Pressures can dive so quickly.O2, Norvasc, Cardizem, Toprol - - - - Anti- platelets: Aspirin, plavix, ticlid, persantine.

Drugs to thin the blood cause anti- coag-ulation

Heparin, Lovenox, Fragmin, Innohep . . . halts thrombin formation

Labs for therapeutic IV heparin - high serial PTT - The enemy is HIT

so look out for low platelet levels please! Coumadin takes days to reach it’s peak Duration 3-5 , almost a week.

If PT/INR is way too high, Aquamephyton(Vitamin K) saves the day!

Anti-infectives target and kill any foe. Foreigners the body does not know.

Penicillins, Cephlasporins, Macrolides. Tetracyclines, Sulfonamides.

Antifungals, Aminoglycosides, Meds make it difficult for microbes to survive!

As you can see a drug book you will need.

No song is long enough to teach all Pharmacology!
