NSG 6005 FINAL STUDY GUIDE
Guanfacine- used to treat HTN or ADHD, non stimulant. Alpha 2 adrenergic agonist.
Antiarrhythmics start on p. 322
Class I: sodium channel blockers
Class Ia: lengthens action potential (quinidine, procainamide[requires freq.dosing],
disopyramide)
Class Ib: shortens action potential (lidocaine, phenytoin) treats ventricular arrhythmias
Class Ic: minimal or no effect on action potential; severe ventricular tachycardias- where
no other drugs have worked
Class II: beta blockers (propranolol, metoprolol, atenolol)- indirectly reduces slope by blocking
chronotropic impact of norepinephrine
Atenolol has longer half-life than metoprolol
Class III: agents that lengthen action potential (potassium channel blockers)–(amiodarone,
bretyllium) effective in treating re-entry problems, inhibits v-fib due to myocardial ischemia,
improves contractility
Class IV: Calcium channel blockers(verapamil, diltiazem, bepridil)& (amlodipine, felodipine)
2 types of CCB:
type I- non-hydropyridines-affect conduction through AV node, have neg chronotropic effect
(verapamil, diltiazem)
type II:hydorphyridines-do not affect conduction through AV node (nifedipine, amlodipine,
felodipine)
Class IA & IC -what is similar?
Lidocaine-
Amiodaraone effective against supraventricular rhythms
BPH & HTN med
Doxazosin- used to treat BPH & HTN
Mexiletine- only available orally
,Valerian has no adverse reactions when used at the recommended level; however, overdosage at
2.5 g or more can cause cardiac disturbance, excitability, headache, insomnia, and nausea. It can
potentiate alcohol and other CNS depressants if taken in large amounts. (p. 139)
Ayurvedic medicine- Although all three doshas exist together, often plants and people are
classified by the one that is most dominant in them, referred to as the person’s “Prakruti,” and
specific to them as an individual. (p. 132)
Glaucoma meds:
Longer eyelashes-lanasoprost or bimatoprost – prostaglandin drugs
Glaucoma med cause blurriness after instilled into eyes for few minutes
Procainamide-short acting; need dose reduction in CHF and renal impairment (p. 325)
VLDL- synthesized in the liver (p. 1130) Drugs that inhibit VLDL synthesis in the liver (niacin,
fibric acid derivatives) also reduce LDLs via the endogenous pathway (p.1130).
Cholesterol meds:
-acted on sterols?
Inhibitor Hmgcoa- statins
Bile from liver-bile sequestrins
Cost benefit analysis
Cardiotonic
Digoxin with renal failure- contradicted in renal impairment; Digoxin can also be problematic
when treating older adults and patients with renal insufficiency. Renal function may decrease
during heart failure treatment and the drug may not be adequately excreted, allowing it to
increase to toxic levels. Digoxin levels should be closely monitored in these patients. (p. 1072)
Because digoxin is excreted essentially unchanged by the kidneys, severe renal impairment
effectively contraindicates its use. (p. 318)
Treatment with hepatitis C- antiviral meds, NS5A inhibitors
Tacrine-
Timolol-
,The nurse concludes that a client newly diagnosed with glaucoma knows the purpose for the
prescribed timolol (Timoptic) blocker when the clients makes which statement:
- REDUCE INTRAOCCULAR PRESSURE
Cromolyn-allergic
David presents to clinic with symptoms of allergic conjunctivitis. He is prescribed cromolyn
sodium (Opticrom) eyedrops. The education regarding using cromolyn eyedrops includes which
one of the following tips
- he should not wear his soft contacts while using the cromolyn eyedrops.
PNA & hypothyroidism- what med don’t give?? -epi inhaler
Which class antiarrhythmic meds treat SVT or VT?
HSV med- answer to do with applying to oral lesion at the first sign of outbreak
Protozoal infection- which type of med antifungal, antimalarial or antiviral plus one other I can’t
remember
Erectile dysfunction- sildenafil or something
It must be noted that phosphodiesterase-5 inhibitors (sildenafil, Viagra; vardenafil, Levitra;
tadalafil, Cialis) used to treat erectile dysfunction, when taken in combination with nitrates used
for chest pain, can cause severe vasodilation resulting in hypotension and syncope. (p. 892)
Patients with Wolff–Parkinson–White (WPW) syndrome can have ventricular responses that are
dangerously rapid. Drugs commonly used to control ventricular response such as diltiazem,
verapamil, and digoxin are ineffective in this situation and can facilitate conduction through the
accessory pathway, increasing the risk for ventricular fibrillation (p. 315)
, Final exam pharm
