    1. APropranolol
    2. BAtenolol
    3. CLosartan
    4. DMethyldopa
    5. ENifedipine
  2. 2A patient is admitted to the emergency department with
    severe tachycardia after a drug overdose. His family reports
    that he has been depressed about his hypertension. Which
    one of the following drugs increases the heart rate in a dosedependent
    manner?
    1. ACaptopril
    2. BHydrochlorothiazide
    3. CLosartan
    4. DMinoxidil
    5. EVerapamil
  3. 3Which one of the following is characteristic of nifedipine
    treatment in patients with essential hypertension?
    1. ACompetitively blocks angiotensin II at its receptor
    2. BDecreases calcium efflux from skeletal muscle
    3. CDecreases renin concentration in the blood
    4. DDecreases calcium influx into smooth muscle
    5. EDecreases calcium flux into the urine
  4. 4A 73-year-old man with a history of a recent change in his
    treatment for moderately severe hypertension is brought to
    the emergency department because of a fall at home. Which
    of the following drug groups is most likely to cause postural
    hypotension and thus an increased risk of falls?
    1. AACE inhibitors
    2. BAlpha1-selective receptor blockers
    3. CArteriolar dilators
    4. DBeta1-selective receptor blockers
    5. ENonselective β blockers
  5. 5Which of the following is very short-acting and acts by releasing
    nitric oxide?
    1. AAtenolol
    2. BCaptopril
    3. CDiltiazem
    4. DFenoldopam
    5. EHydrochlorothiazide
    6. FLosartan
    7. GMinoxidil
    8. HNitroprusside
    9. IPrazosin
  6. 6In deciding on a treatment regimen with procainamide
    for this patient, which of the following statements is most
    correct?
    1. AA possible drug interaction with digoxin suggests that
      digoxin blood levels should be obtained before and after
      starting procainamide
    2. BHyperkalemia should be avoided to reduce the likelihood
      of procainamide toxicity
    3. CProcainamide cannot be used if the patient has asthma
      because it has a β-blocking effect
    4. DProcainamide cannot be used if the patient has angina
      because it has a β-agonist effect
    5. EProcainamide is not active by the oral route
  7. 7If this patient should take an overdose and manifest severe
    acute procainamide toxicity with markedly prolonged QRS,
    which of the following should be given immediately?
    1. AA calcium chelator such as EDTA
    2. BDigitalis
    3. CNitroprusside
    4. DPotassium chloride
    5. ESodium lactate
  8. 8A 57-year-old man is admitted to the emergency department
    with chest pain and a fast irregular heart rhythm. The
    ECG shows an inferior myocardial infarction and ventricular
    tachycardia. Lidocaine is ordered. When used as an antiarrhythmic
    drug, lidocaine typically
    1. AIncreases action potential duration
    2. BIncreases contractility
    3. CIncreases PR interval
    4. DReduces abnormal automaticity
    5. EReduces resting potential
  9. 9A 36-year-old woman with a history of poorly controlled thyrotoxicosis
    has recurrent episodes of tachycardia with severe
    shortness of breath. When she is admitted to the emergency
    department with one of these episodes, which of the following
    drugs would be most suitable?
    1. AAmiodarone
    2. BDisopyramide
    3. CEsmolol
    4. DQuinidine
    5. EVerapamil
  10. 10A 16-year-old girl has paroxysmal attacks of rapid heart rate
    with palpitations and shortness of breath. These episodes
    occasionally terminate spontaneously but often require a visit
    to the emergency department of the local hospital. Her ECG
    during these episodes reveals an AV nodal tachycardia. The
    antiarrhythmic of choice in most cases of acute AV nodal
    tachycardia is
    1. A(A) Adenosine
    2. B(B) Amiodarone
    3. C(C) Flecainide
    4. D(D) Propranolol
    5. E(E) Verapamil
