Questions on the Respiratory System Questions
Question 1 of 5
Which of the following is a priority goal for the client with COPD?
Correct Answer: A
Rationale: Maintaining functional ability (A) is a priority goal for COPD clients. This chronic, progressive disease limits airflow, reducing exercise tolerance preserving daily activity (e.g., walking, self-care) enhances quality of life and slows decline. Chest pain (B) isn't typical in COPD unless complicated (e.g., pneumothorax) dyspnea dominates. Increasing COâ‚‚ (C) is harmful; COPD often causes hypercapnia, needing reduction. Treating infections (D) is a means, not the goal prevention aids function. Functional ability, supported by rehab and breathing techniques, is a measurable, client-centered outcome, critical in nursing care plans to manage COPD's impact long-term.
Question 2 of 5
In which of the following diseases would the occurrence of hemoptysis prompt a search for another disease as the cause of hemoptysis?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Metastatic brain abscess is a complication of which of the following?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Ventilation (breathing) is a regular, rhythmic process which:
Correct Answer: A
Rationale: Ventilation moves air into and out of the lungs (A) . This mechanical process, driven by inspiratory muscles (diaphragm, intercostals), shifts 500 mL tidal volume 12-15 times/minute (Page 4), per Boyle's law thoracic expansion drops pressure, drawing air in; relaxation expels it. Energy release (B) is cellular respiration, not ventilation. Surface tension reduction (C) is surfactant's role, not breathing's. Mucus clearance (D) involves cilia, not ventilation itself. A's focus on airflow diaphragm drops 1-2 cm, expanding thorax 5-7 cm distinguishes it from B's metabolic or C's chemical roles, aligning with respiratory physiology (Page 2, ventilation definition).
Question 5 of 5
Which of the following is NOT true at FRC?
Correct Answer: B
Rationale: At functional residual capacity (FRC), the lung-thorax system rests (D), with lung recoil inward (C) balanced by chest wall recoil outward (B) . FRC is ~2.5-3 L, roughly 50% of TLC (~6 L), not 75% (A), making A false. At FRC, intrapleural pressure is -5 cm H2O, and alveolar pressure equals atmospheric (0 cm H2O). B's outward chest recoil is true, opposing C's inward lung pull, stabilizing D's rest state. A's exaggeration 75% TLC (~4.5 L) overshoots FRC's role as post-expiratory equilibrium, where diaphragm relaxes and no airflow occurs, per physiology.
