1. In the treatment of allergic rhinitis, which of the following should be limited to no more than 5
consecutive days?
Topical vasoconstrictors because of RISK OF REBOUND CONGESTION, pg. 242
2. The patient must be informed of possible damage to the lungs when prescribed oral therapy
with which of the following drugs: Amiodarone, pg. 101
3. Although aspirin is often combined with P2Y12 adenosine diphosphate receptor antagonists, its
use with these agents may: INCREASE THE RISK OF GI BLEEDS, both combined suppress platelet
aggregation.
4. CCB that are dihydropyridines: are often combined with a BB to suppress reflex tachycardia.
5. Which of the following statements is true: pg. 246
True: Dextromethorphan has not been shown to be effective in suppressing cough associated
with the common cold.
False: Antihistamines reduce itching, sneezing, and congestion (does not reduce congestion),
oral sympathomimetics can cause rebound congestion (only topical), Guaifenesin acts by
promoting a more vigorous cough (productive cough).
6. A patient has inadvertently overdosed on warfarin. To reverse the bleeding caused by this drug,
the patient will be treated with: Vitamin K, aka antidote PHYTONADIONE, pg. 154
7. With most of the ACEI that are approved for heart failure: starting doses are lower than they
are for the patient taking them for hypertension. Pg. 75
8. Of the following, the patient who is a candidate for Dronedarone would be: pg. 102 Yes: patient
with paroxysmal a fib, depressed, and on a TCA.
Contraindicated in: The patient prescribed Clarithromycin for a sinus infection and who has
atrial flutter, pregnant patient with permanent a fib, and a patient on verapamil with persistent
a-fib.
9. When comparing ACEI to ARBS, the NP knows that: ANSWER IN 2nd EDITION Both ACE/ARBs may
cause renal failure in a patient with bilateral renal stenosis. ACE inhibitors cause hyperkalemia
and decrease responses to digoxin, ARBS are recommended if ACE drugs are not tolerated, both
are contraindicated in pregnancy, both cause angioedema.
10. A patient receiving heparin therapy has a platelet count of 20,000/mm3. Appropriate therapy
would include: DISCONTINUE Heparin and start anticoagulant therapy with Argatroban, pg. 151,
ANTIDOTE FOR HIT---PROTAMINE SULFATE
11. Which of the following is true regarding antitussives: pg. 244
True: Dextromethorphan can cause CNS effects, including EUPHORIA if taken in high doses.
False: 1) Benzonatate capsules can be sucked like a lozenge (they need to be swallowed,
otherwise they will cause laryngospasm/bronchospasm/circulatory collapse), 2) codeine is safe
in children, 3) diphenhydramine is non-sedating option to treating cough due to the common
cold.
