Charlie is a 65 year-old male who has been diagnosed with HTN and BPH. Doxazosin has been chosen to treat his HTN because it:

To reduce potential adverse effects, patients taking a peripherally acting alpha 1 antagonist should do all of the following EXCEPT:
monitor their blood pressure and skip a dose if their pressure is less than 120/80
John has clonidine, a centrally acting adrenergic blocker, prescribed for his HTN. He should:
Not miss a dose or stop taking the drug because of potential rebound HTN.
Clonidine has several off-label uses including:
both 1 & 2
1.alcohol and nicotine with-drawl
2.post-herpetic neuralgia
Jim is being treated for HTN. Because he has history of heart attack, the drug chosen is atenolol. Beta-blockers treat HTN by:
reducing vascular smooth muscle tone
which of the following adverse effects are less likely in a beta 1 - selective blocker
impaired insulin release
Richard is 70 years old and has a history of cardiac dysrhythmias. He has been prescribed nadolol. You do his annual lab work and find CrCl of 25 ml/min, What action should you take?
extend the dosage interval
Beta blockers are the drugs of choice for exertional angina because they:
decrease myocardial oxygen demand by decreasing heart rate and vascular resistance
adherence to beta blocker therapy may be affected by their:
effects on the male genitalia, which may produce impotence
beta blockers have favorable effects on survival and disease progression in heart failure. Treatment should be initiated when the:
left ventricular function is diagnosed
abrupt withdrawal of beta blockers can be life threatening. Patients at highest risk of for serious consequences of rapid withdrawal are those with:
both 1 and 2
1. angina
2. coronary artery disease
to prevent life threatening from rapid withdrawal of a beta blocker:
the dosage should be decreased by 1/2 every 4 days
beta blockers are prescribed for diabetics with caution because of their ability to produce hypoglycemia and block the common symptoms of it. Which of the following symptoms of hypoglycemia is not blocked by these drugs and so can be used to warn diabetics of possible decreased blood glucose?
diaphoresis
combined alpha-beta antagonists are used to reduce the progression of heart failure because they:
vasodilate the peripheral vasculature
carvedilol is heavily metabolized by CYP2D6 and 2C9, resulting in drug interactions with which of the following drug classes:
all the above:
histamine 2 blockers
quinolones
serotonin re-uptake inhibitors
alpha-beta blockers are especially effective to treat HTN for which ethnic group:
african-american
bethanechol:
increases detrusor muscle tone to empty the bladder
clinical dosing of bethanechol:
starts at 5mg to 10mg PO and is repeated every hour until a satisfactory clinical response is achieved
patients who need to remain alert are taught to avoid which drug due to its antimuscarinic effects:
diphenhydramine
anticholinesterase inhibitors are used to treat:
myasthenia gravis
which of the following drugs used to treat Alzheimers disease is not an anticholinergic:
memantine
taking which drug with food maximizes its bioavailability:
Rivastigmine
which of the following drugs should be used only when clearly needed in pregnant and breastfeeding women:
Pyridostigmine
There is a narrow margin between first appearance of adverse reaction to AChE inhibitors and serious toxic effects. Adverse reactions that require immediate action include:
Fasciculations of voluntary muscles
