Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. Which of the following medications is considered the gold standard for the
treatment of an acute asthma exacerbation?
A. Salmeterol
B. Fluticasone
C. Albuterol
D. Montelukast
Correct Answer: C
Expert Explanation: Albuterol is a short-acting beta-agonist (SABA) that provides
rapid bronchodilation during acute symptoms. It works by stimulating beta-2
receptors in the lungs to relax smooth muscle. Patients should be taught to use this
as a rescue inhaler rather than for daily maintenance.
2. A patient with COPD is prescribed Tiotropium (Spiriva). What is the primary
mechanism of action for this drug?
A. Inhibition of muscarinic cholinergic receptors
B. Activation of beta-2 adrenergic receptors
,C. Suppression of inflammatory mediators
D. Inhibition of leukotriene synthesis
Correct Answer: A
Expert Explanation: Tiotropium is a long-acting muscarinic antagonist (LAMA)
that blocks acetylcholine at muscarinic receptors in the airways. This action
prevents bronchoconstriction and reduces mucus secretion in COPD patients. It is
intended for long-term maintenance rather than acute relief.
3. What is the most common side effect associated with the use of inhaled
corticosteroids (ICS) like Fluticasone?
A. Rebound congestion
B. Tachycardia
C. Hypokalemia
D. Oropharyngeal candidiasis
Correct Answer: D
Expert Explanation: Inhaled corticosteroids can leave residue in the mouth that
suppresses local immunity, leading to fungal infections like thrush. Patients are
strictly advised to rinse their mouth and spit after each use to minimize this risk.
,This localized side effect is more common than systemic steroid effects when used
at appropriate doses.
4. A patient is diagnosed with H. pylori-positive peptic ulcer disease. Which
combination is typically included in triple therapy?
A. Antacid, Misoprostol, and Amoxicillin
B. H2 blocker, Sucralfate, and Metronidazole
C. PPI, Bismuth, and Tetracycline
D. PPI, Amoxicillin, and Clarithromycin
Correct Answer: D
Expert Explanation: Standard triple therapy consists of a Proton Pump Inhibitor
(PPI) and two antibiotics, usually Amoxicillin and Clarithromycin. This regimen
targets the bacteria while reducing acid to allow the ulcer to heal. If the patient has a
penicillin allergy, Metronidazole is often substituted for Amoxicillin.
5. Which medication is a Black Box Warning for neuropsychiatric events, such as
suicidal ideation, in both adults and children?
A. Theophylline
B. Cromolyn sodium
C. Montelukast
, D. Omeprazole
Correct Answer: C
Expert Explanation: Montelukast (Singulair) carries a significant Black Box
Warning regarding serious mental health side effects. Clinicians must monitor
patients for changes in behavior, aggression, or suicidal thoughts. This risk must be
weighed against its benefits in treating asthma and allergic rhinitis.
6. Long-term use of Proton Pump Inhibitors (PPIs) has been associated with which
nutritional deficiency?
A. Vitamin B12
B. Vitamin C
C. Vitamin A
D. Folic acid
Correct Answer: A
Expert Explanation: PPIs significantly reduce gastric acid secretion, which is
necessary for the absorption of Vitamin B12 from food. Chronic suppression can
eventually lead to deficiency and potential neurological issues. Monitoring B12
levels is recommended for patients on therapy for longer than one year.
