TOPIC 1: CHRONIC RESPIRATORY CONDITIONS
6 Questions • 7.5% of Exam • Focuses on the assessment and management of chronic respiratory diseases.
QUESTION 1
SOB when lying down, and moving around --Based on the patient's presentation, which
disease process is the patient likely exhibiting?
Correct Answer: Asthma.
Rationale: The patient's symptoms of shortness of breath (SOB) when lying down and improvement with movement
suggest that they are experiencing orthopnea, a classic symptom of heart failure. However, the presence of orthopnea
typically worsens with exertion, which contradicts the patient's symptoms; instead, asthma exacerbations are known to
worsen with exertion due to increased airway resistance and inflammation, making it the more likely diagnosis.
QUESTION 2
A 28-year-old married female presents to primary care accompanied by her husband
with complaints of weight gain, fatigue, muscle aches, bloating, constipation, and
difficulty concentrating. The patient explains that she has been experiencing these
symptoms with increasing frequency over the last two months and reports feeling
upset that she has gained 10 pounds over the past month despite no significant
changes in dietary intake or activity level. The patient holds a bachelor's degree and is
employed full time as an accountant. The patient reports feeling frustrated with her
poor concentration and identifies recent work errors to be due to this symptom. The
patient explains that she and her spouse plan to start trying to conceive soon, and she
is worried that she may have trouble becoming pregnant. The patient reports using
over-the-counter laxative products over the last week to combat constipation. The
patient repo
Correct Answer: 5.31 MIU/L.
Rationale: The patient's symptoms, such as weight gain, fatigue, muscle aches, bloating, constipation, and difficulty
concentrating, are suggestive of hyperthyroidism, a condition characterized by an overproduction of thyroid hormones,
which can be caused by thyroid-stimulating immunoglobulins (TSI) and other autoantibodies. The measurement of 5.31
mIU/L for Thyroid-Stimulating Immunoglobulins (TSI) is likely a reference to the diagnosis of Graves' disease, an
autoimmune form of hyperthyroidism, which is supported by the patient's recent weight gain, changes in thyroid hormone
levels, and plans to conceive.

QUESTION 3
An emergency room (ER) nurse is in a room caring for a patient when the ER suddenly
becomes very busy and fills all available rooms. When the nurse completes the care of
the current patient, he finds an emergency medical technician (EMT) ready to report on
each of the new patients. Which patient from the report should be seen first?
Correct Answer: The 40-year-old male with crushing chest pain who denies any injury or prior history of
heart disease.
Rationale: The nurse should prioritize the patient with crushing chest pain who denies any injury or prior history of heart
disease because this symptom is a classic sign of acute myocardial infarction, a life-threatening condition that requires
immediate medical attention. This patient's presentation is likely to be a medical emergency, and timely intervention can
significantly impact their outcome, making it the top priority among the new patients.
QUESTION 4
What is the intended therapeutic action of inhaled corticosteroids in patients with
chronic respiratory conditions
[A] Reversal of fixed airway obstruction
[B] Improvement of central respiratory drive
[C] Reduction of airway inflammation
[D] mucolytic activity
Correct Answer: Reduction of airway inflammation
--Topical corticosteroids work to decrease inflammation locally where applied.
Rationale: Inhaled corticosteroids target the lungs directly, allowing them to effectively reduce inflammation in the airways
without the systemic side effects associated with oral corticosteroids, making them a preferred treatment option for patients
with chronic respiratory
conditions. This therapeutic action is particularly beneficial in managing conditions such as asthma, where chronic
inflammation of the airways is a key component of the disease pathophysiology.
