NR 566 ADVANCED PHARMACOLOGY MIDTERM EXAM:
200 COMPREHENSIVE EXAM QUESTIONS AND
RATIONALES
1. Which antibiotic is recommended as a second-line treatment for
community-acquired pneumonia (CAP) when amoxicillin fails due to
its effectiveness against a broader range of pathogens?
A. Azithromycin
B. Doxycycline
C. Cephalexin
D. Levofloxacin
Rationale: Doxycycline is effective against atypical pathogens and
broader bacteria that may not respond to amoxicillin, making it a
suitable second-line option for CAP.
2. A patient using benzoyl peroxide for acne treatment should be
counseled that which adverse effect is most commonly expected?
A. Brown scaling
B. Photosensitivity
C. Pseudomembrane colitis
D. Stinging skin
Rationale: Benzoyl peroxide frequently causes local irritation, including
stinging, burning, and peeling at the application site.
3. Which class of weight loss medications has been linked to an
increased risk of suicide in younger populations, requiring close
monitoring?
A. Lipase inhibitors
,B. GLP-1 receptor agonists
C. Sympathomimetic amines
D. Biguanides
Rationale: GLP-1 receptor agonists have been associated with reports of
suicidal ideation, particularly in younger patients, prompting regulatory
safety reviews.
4. Which antifungal agent is considered the drug of choice for invasive
aspergillosis in immunocompromised patients?
A. Fluconazole
B. Nystatin
C. Voriconazole
D. Terbinafine
Rationale: Voriconazole is the primary treatment for invasive
aspergillosis due to its broad spectrum and efficacy against Aspergillus
species.
5. A patient with a penicillin allergy requires treatment for CAP. Which
medication is the preferred first-line alternative?
A. Amoxicillin
B. Cephalexin
C. Doxycycline
D. Trimethoprim-sulfamethoxazole
Rationale: Doxycycline is a recommended first-line alternative for
healthy adults with CAP who have a penicillin allergy.
6. Which adverse effect is associated with the use of tetracycline
antibiotics in children under 8 years old?
A. Tooth discoloration
B. Photosensitivity
,C. Stinging skin
D. Pseudomembrane colitis
Rationale: Tetracyclines bind to calcium in developing teeth, causing
permanent yellow-gray-brown discoloration and enamel hypoplasia.
7. A patient on warfarin therapy should maintain consistent intake of
which vitamin to avoid INR fluctuations?
A. Vitamin C
B. Vitamin K
C. Vitamin D
D. Vitamin B12
Rationale: Vitamin K antagonizes warfarin's anticoagulant effect, so
consistent dietary intake is crucial to maintain therapeutic INR levels.
8. Which medication is a first-line treatment for hypertension in a
patient with diabetes and proteinuria?
A. Amlodipine
B. Lisinopril
C. Metoprolol
D. Hydrochlorothiazide
Rationale: ACE inhibitors like lisinopril are preferred in diabetics with
proteinuria due to their renoprotective effects.
9. Which adverse effect is characterized by a dry, persistent cough and
is associated with ACE inhibitors?
A. Angioedema
B. Bradykinin accumulation
C. Hyperkalemia
D. Hypotension
, Rationale: ACE inhibitors block the breakdown of bradykinin, leading to
its accumulation, which causes a dry, persistent cough.
10. Which medication is indicated for the treatment of influenza A and
B within 48 hours of symptom onset?
A. Acyclovir
B. Oseltamivir
C. Valacyclovir
D. Ganciclovir
Rationale: Oseltamivir is a neuraminidase inhibitor effective against
influenza A and B when initiated within 48 hours of symptom onset.
11. Which medication is a long-acting beta-agonist (LABA) used for
maintenance therapy in COPD but should never be used as
monotherapy in asthma?
A. Albuterol
B. Salmeterol
C. Ipratropium
D. Theophylline
Rationale: LABAs like salmeterol must be used in combination with an
inhaled corticosteroid in asthma due to the risk of severe exacerbations.
12. A patient with hypothyroidism is prescribed levothyroxine. Which
instruction should the nurse provide regarding administration?
A. Take with food to avoid GI upset
B. Take on an empty stomach 30-60 minutes before breakfast
C. Take at bedtime with a glass of milk
D. Take with calcium supplements
Rationale: Levothyroxine absorption is best on an empty stomach. Food,
especially calcium and iron, significantly impairs its absorption.
