PNVN 1631 Exam 2 / Module Exams Practice Questions (2026-
2027) Complete Verified Updated!!!!!
Instructions: This exam consists of multiple-choice questions.
Choose the best answer for each question. The questions are
organized by major topic areas based on the PNVN 1631
curriculum.
Section 1: Respiratory Pharmacology & Bronchodilators
(Questions)
1. A patient is prescribed albuterol (Proventil) for newly
diagnosed asthma. When teaching the patient about this drug,
the nurse should explain that it may cause:
A) Nasal congestion
B) Nervousness
C) Lethargy
D) Hyperkalemia
Answer: B
Rationale: Albuterol is a beta-2 adrenergic agonist that can
cause nervousness, tremors, and tachycardia due to
sympathetic nervous system stimulation.

2. Which of the following drugs is a short-acting
bronchodilator used for the relief of acute bronchospasm?
A) Montelukast
B) Ipratropium
C) Beclomethasone
D) Salbutamol
Answer: D
Rationale: Salbutamol (albuterol) is a short-acting beta-2
agonist used for acute bronchospasm relief.
3. A young adult presents to the emergency department with
acute severe asthma and receives albuterol nebulization. Soon
after administration, he develops mild tachycardia and
tremors. Which autonomic receptor activation is responsible
for both the therapeutic bronchodilation and these systemic
side effects?
A) α1-adrenergic receptor
B) β1-adrenergic receptor
C) β2-adrenergic receptor
D) M2 muscarinic receptor
Answer: C
Rationale: Albuterol is a β2-adrenergic receptor agonist leading
to bronchodilation via increased cAMP. β2 receptors are also
expressed in the heart and skeletal muscle, causing tachycardia
and tremors.

4. Which medication is a combined Long-Acting Beta Agonist
(LABA) and a Long-Acting Muscarinic Agent (LAMA)?
A) Onbrez Breezhaler
B) Flovent Diskus
C) Spiriva Respimat
D) Anoro Ellipta
Answer: D
Rationale: Anoro Ellipta is a combination of a LABA and a LAMA
used for COPD maintenance.
5. Which of the following medications is a leukotriene
receptor antagonist used in the treatment of asthma?
A) Salbutamol
B) Fluticasone
C) Zafirlukast
D) Cromolyn
Answer: C
Rationale: Zafirlukast is a leukotriene receptor antagonist used
for asthma prophylaxis.
6. Which of the following medications is a long-acting
muscarinic antagonist (LAMA)?
A) Salmeterol
B) Tiotropium
C) Omalizumab
D) Nedocromil
, Page |4
Answer: B
Rationale: Tiotropium (Spiriva) is a long-acting muscarinic
antagonist used for COPD maintenance.
7. A 55-year-old female with a history of asthma experiences
exacerbation characterized by bronchospasm. She is
prescribed a medication that prevents acetylcholine binding at
muscarinic receptors on airway smooth muscles. However, she
later complains of dry mouth and urinary retention. Which
receptor subtype blockade explains both therapeutic and side
effects?
A) M1 muscarinic receptors
B) M2 muscarinic receptors
C) M3 muscarinic receptors
D) Nicotinic receptors
Answer: C
Rationale: Bronchodilation results from blockade of M3
receptors on bronchial smooth muscle. M3 receptors are also
found in exocrine glands (salivary glands) and bladder detrusor
muscle; their blockade causes dry mouth and urinary retention.
8. A 60-year-old man with COPD is prescribed tiotropium for
maintenance therapy. He asks how the medication helps his
breathing. Which of the following best describes the
mechanism by which tiotropium improves airflow?
A) Activation of β2-adrenergic receptors
