Question 1
A nurse is performing a respiratory assessment and notes a patient has a high-pitched, musical sound heard during
inspiration. How should the nurse document this finding?
A. Wheezes
B. Stridor
C. Crackles
D. Rhonchi
Answer: B
Rationale
Stridor is a high-pitched, monophonic, inspiratory, musical sound caused by an obstruction in the upper airway (larynx or
trachea) and is considered a medical emergency. Understanding this concept is essential for safe clinical decision-making.
Incorrect choices often reflect common misconceptions. Always link assessment findings to the primary process and
anticipated complications.
Question 2
Which stage of pressure injury involves full-thickness skin loss with visible adipose tissue and epibole (rolled wound
edges)?
A. Stage II
B. Unstageable
C. Stage IV
D. Stage III
Answer: D
Rationale
Stage III pressure injuries involve full-thickness skin loss where adipose tissue is visible, but bone, tendon, or muscle are not
exposed. Stage IV involves exposed bone or muscle. Understanding this concept is essential for safe clinical decision-making.
Incorrect choices often reflect common misconceptions. Always link assessment findings to the primary process and
anticipated complications.
Question 3
A patient with chronic obstructive pulmonary disease (COPD) requires low-flow oxygen therapy. Which delivery device
is most appropriate for a precise concentration of oxygen?
A. Nasal cannula
B. Venturi mask
C. Simple face mask
D. Non-rebreather mask
Answer: B
Rationale
The Venturi mask is the most accurate device for delivering specific oxygen concentrations, which is critical for COPD patients
to avoid suppressing their hypoxic drive. Understanding this concept is essential for safe clinical decision-making. Incorrect
choices often reflect common misconceptions. Always link assessment findings to the primary process and anticipated
complications.
