NSG 6005 WEEK 5 QUIZ
____
1.Charlie is a 65-year-old male who has been diagnosed with hypertension and benign prostatic
hyperplasia. Doxazosin has been chosen to treat his hypertension because it:
1. Increases peripheral vasoconstriction
2. Decreases detrusor muscle contractility
3. Lowers supine blood pressure more than standing pressure
4. Relaxes smooth muscle in the bladder neck
____ 2. To reduce potential adverse effects, patients taking a peripherally acting alpha1
antagonist should do all of the following EXCEPT:
1. Take the dose at bedtime
2. Sit up slowly and dangle their feet before standing
3. Monitor their blood pressure and skip a dose if the pressure is less than
120/80
4. Weigh daily and report weight gain of greater than 2 pounds in one day
____ 3. John has clonidine, a centrally acting adrenergic blocker, prescribed for his
hypertension. He should:
1. Not miss a dose or stop taking the drug because of potential rebound
hypertension
2. Increase fiber in the diet to treat any diarrhea that may occur
3. Reduce fluid intake to less than 2 liters per day to prevent fluid
retention
4. Avoid sitting for long periods, as this can lead to deep vein thrombosis
____ 4. Clonidine has several off-label uses, including:
1. Alcohol and nicotine withdrawal
2. Post-herpetic neuralgia
3. Both 1 and 2
4. Neither 1 nor 2
____ 5. Jim is being treated for hypertension. Because he has a history of heart attack, the
drug chosen is atenolol. Beta blockers treat hypertension by:
, 1. Increasing heart rate to improve cardiac output
2. Reducing vascular smooth muscle tone
3. Increasing aldosterone-mediated volume activity
4. Reducing aqueous humor production
____ 6. Which of the following adverse effects are less likely in a beta1-selective blocker?
1. Dysrhythmias
2. Impaired insulin release
3. Reflex orthostatic changes
4. Decreased triglycerides and cholesterol
____ 7. Richard is 70 years old and has a history of cardiac dysrhythmias. He has been
prescribed nadolol. You do his annual laboratory work and find a CrCl of 25 ml/min.
What action should you take related to his nadolol?
1. Extend the dosage interval.
2. Decrease the dose by 75%.
3. Take no action because this value is expected in the older adult.
4. Schedule a serum creatinine level to validate the CrCl value.
____ 8. Beta blockers are the drugs of choice for exertional angina because they:
1. Improve myocardial oxygen supply by vasodilating the coronary
arteries
2. Decrease myocardial oxygen demand by decreasing heart rate and
vascular resistance
3. Both 1 and 2
4. Neither 1 nor 2
____ 9. Adherence to beta blocker therapy may be affected by their:
1. Short half-lives requiring twice daily dosing
2. Tendency to elevate lipid levels
3. Effects on the male genitalia, which may produce impotence
4. None of the above
____10. Beta blockers have favorable effects on survival and disease progression in heart
failure. Treatment should be initiated when the:
, 1. Symptoms are severe
2. Patient has not responded to other therapies
3. Patient has concurrent hypertension
4. Left ventricular dysfunction is diagnosed
____11. Abrupt withdrawal of beta blockers can be life threatening. Patients at highest risk for
serious consequences of rapid withdrawal are those with:
1. Angina
2. Coronary artery disease
3. Both 1 and 2
4. Neither 1 nor 2
____12. To prevent life-threatening events from rapid withdrawal of a beta blocker:
1. The dosage interval should be increased by 1 hour each day.
2. An alpha blocker should be added to the treatment regimen before
withdrawal.
3. The dosage should be tapered over a period of weeks.
4. The dosage should be decreased by one-half every 4 days.
____13. 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?
1. Dizziness
2. Increased heart rate
3. Nervousness and shakiness
4. Diaphoresis
____14. Combined alpha-beta antagonists are used to reduce the progression of heart failure
because they:
1. Vasodilate the peripheral vasculature
2. Decrease cardiac output
3. Increase renal vascular resistance
4. Reduce atherosclerosis secondary to elevated serum lipoproteins
, ____15. Carvedilol is heavily metabolized by CYP2D6 and 2C9, resulting in drug interactions
with which of the following drug classes?
1. Histamine 2 blockers
2. Quinolones
3. Serotonin re-uptake inhibitors
4. All of the above
____16. Alpha-beta blockers are especially effective to treat hypertension for which ethnic
group?
1. White
2. Asian
3. African American
4. Native American
____17. Bethanechol:
1. Increases detrusor muscle tone to empty the bladder
2. Decreases gastric acid secretion to treat peptic ulcer disease
3. Stimulates voluntary muscle tone to improve strength
4. Reduces bronchial airway constriction to treat asthma
____18. Clinical dosing of Bethanechol:
1. Begins at the highest effective dose to obtain a rapid response
2. Starts at 5 mg to 10 mg PO and is repeated every hour until a
satisfactory clinical response is achieved
3. Requires dosing only once daily
4. Is the same for both the oral and parenteral route
____19. Patients who need to remain alert are taught to avoid which drug due to its
antimuscarinic effects?
1. Levothyroxine
2. Prilosec
3. Dulcolax
4. Diphenhydramine
____20. Anticholinesterase inhibitors are used to treat:
____
