Chapter 41 Oxygenation NCLEX Questions Questions
Question 1 of 5
Which position improves breathing mechanics in COPD?
Correct Answer: B
Rationale: Patients with COPD improve the mechanics of breathing by sitting up in the 'tripod' position. Resting in bed with the head elevated in a semi-Fowler's position would be an alternative position if the patient was confined to bed, but sitting in a chair allows better ventilation.
Question 2 of 5
A 3-month-old infant is at increased risk for developing anemia. The nurse would identify which principle contributing to this risk?
Correct Answer: C
Rationale: Infants at 3 months rely on depleting iron stores from birth, and breast milk or formula alone may not provide sufficient iron, increasing anemia risk.
Question 3 of 5
A nurse cares for a client with arthritis who reports frequent asthma attacks. What action would the nurse take first?
Correct Answer: B
Rationale: Aspirin and NSAIDs, used for arthritis, can trigger asthma, making medication history the priority.
Question 4 of 5
A nurse cares for a client who has advanced cardiac disease and states, 'I am having trouble breathing while I'm sleeping at night.' What is the nurse's best response?
Correct Answer: D
Rationale: Elevating the head and chest can alleviate orthopnea, a common symptom in advanced cardiac disease.
Question 5 of 5
When auscultating the lungs of a client experiencing dyspnea, the nurse hears a low-pitched sound that is continuous throughout inspiration. What does this lung sound indicate?
Correct Answer: A
Rationale: Rhonchi are low-pitched, continuous sounds heard during inspiration, often due to secretions in the larger airways, and may be cleared with coughing. Stridor is a high-pitched sound from narrow tracheal passages, pleural friction rub is a grating sound from inflamed pleural surfaces, and wheezing is a high-pitched sound from narrow bronchi.
