Question | Chamberlain
1. A 24-year-old patient with asthma is prescribed Albuterol for rescue use. Which of
the following is the primary mechanism of action for this medication?
A. Stimulation of beta-2 adrenergic receptors
B. Antagonism of muscarinic receptors
C. Inhibition of leukotriene synthesis
D. Reduction of systemic inflammation
Correct Answer: A
Expert Explanation: Albuterol is a short-acting beta-agonist (SABA) that selectively
stimulates beta-2 adrenergic receptors in the lungs. This stimulation leads to the
relaxation of bronchial smooth muscles and subsequent bronchodilation. It is the
drug of choice for acute bronchospasm and exercise-induced asthma relief.
2. When prescribing an inhaled corticosteroid (ICS) like Fluticasone, which instruction
is most important to prevent local adverse effects?
A. Take the medication only when feeling short of breath.
B. Avoid drinking fluids for 30 minutes after inhalation.
,C. Double the dose if a day of treatment is missed.
D. Use a spacer and rinse the mouth with water after use.
Correct Answer: D
Expert Explanation: Inhaled corticosteroids can cause local side effects such as
oropharyngeal candidiasis (thrush) and dysphonia. Using a spacer helps deliver
more medication to the lungs and less to the back of the throat. Rinsing the mouth
with water and spitting it out after use effectively removes residual steroid particles
from the oral cavity.
3. A patient is being started on Montelukast (Singulair) for allergic rhinitis and asthma.
The nurse practitioner must educate the patient on which Black Box Warning?
A. Serious neuropsychiatric events
B. Acute liver failure and jaundice
C. Increased risk of sudden cardiac death
D. Tendon rupture and joint pain
Correct Answer: A
Expert Explanation: The FDA issued a Black Box Warning for Montelukast
regarding serious neuropsychiatric events, including agitation, aggression, and
suicidal ideation. Providers should screen patients for pre-existing mental health
,conditions before starting the drug. Patients and families must be instructed to stop
the medication immediately and contact their provider if behavioral changes occur.
4. Long-term use of Proton Pump Inhibitors (PPIs) like Omeprazole has been
associated with which of the following risks?
A. Reduced risk of Clostridium difficile infection
B. Hypermagnesemia and bradycardia
C. Excessive absorption of Vitamin B12
D. Increased risk of bone fractures
Correct Answer: D
Expert Explanation: Long-term PPI therapy is linked to decreased calcium
absorption, which increases the risk of osteoporosis and bone fractures. It can also
cause hypomagnesemia and Vitamin B12 deficiency due to altered gastric acidity.
Patients on chronic therapy should be monitored for these nutritional deficiencies
and bone density issues.
5. Which of the following medications is a Long-Acting Beta Agonist (LABA) that should
never be used as monotherapy for asthma?
A. Salmeterol
B. Ipratropium
, C. Levalbuterol
D. Prednisone
Correct Answer: A
Expert Explanation: Salmeterol is a LABA intended for long-term control of asthma
symptoms and should always be paired with an inhaled corticosteroid. Using LABAs
alone for asthma is associated with an increased risk of asthma-related death. In
contrast, LABAs can be used as monotherapy for COPD management.
6. A patient with COPD is prescribed Tiotropium (Spiriva). What is the mechanism of
action for this medication?
A. Beta-2 receptor agonist
B. Leukotriene receptor antagonist
C. Phosphodiesterase-4 inhibitor
D. Long-acting muscarinic antagonist
Correct Answer: D
Expert Explanation: Tiotropium is a long-acting muscarinic antagonist (LAMA)
that works by blocking M3 receptors on airway smooth muscle. This inhibition
prevents acetylcholine-induced bronchoconstriction, leading to prolonged
