Questions for Respiratory System Questions
Question 1 of 5
A nurse teaches a client about the use of a respiratory inhaler. Which action by the client indicated a need for further teaching?
Correct Answer: C
Rationale: Inhaling the mist and quickly exhaling (C) indicates a need for further teaching. Proper inhaler use requires holding the breath 5-10 seconds after inhalation to deposit medication in airways quick exhalation wastes it, reducing efficacy. Shaking the inhaler (A) mixes contents, pressing while inhaling (B) delivers the dose, and waiting 1-2 minutes between puffs (D) ensures full absorption all correct. This error, common in COPD or asthma clients, undermines treatment, a key nursing focus to retrain for optimal bronchodilator or steroid delivery, enhancing symptom control.

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
43 male patient present to the physician with dyspnea excessive sputum and blue lips and extremities chest radiography showed large heart and prominent blood vessels, which of the following is most likely the diagnosis:
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which of the following structures is NOT part of the upper respiratory tract?
Correct Answer: C
Rationale: The lung (C) isn't upper respiratory . The upper tract nose, pharynx, larynx, epiglottis filters and warms air. The larynx (A) vibrates for speech, epiglottis (D) guards the trachea (B), which links to lower airways. Lungs (C), distal to the trachea, perform gas exchange (300 million alveoli), not air conduction. C's role in exchange unlike A's phonation or B's conduit function excludes it from the upper tract, per anatomy (Page 2).
Question 5 of 5
Regarding dead space, choose the FALSE statement
Correct Answer: C
Rationale: Dead space is gas not exchanging (A, true), but physiological dead space includes anatomic (~150 mL) plus alveolar dead space, not just alveolar (B, false) . It's measured via Bohr's method arterial PCO2 (PaCO2) vs. mixed expired PCO2 (PECO2) not directly by PECO2 alone (C, false). Ventilators add tubing dead space (D, true), and high V/Q ratios increase it (Page 8, Q34). C's oversimplification misses PaCO2's role (e.g., Q12: 600 mL tidal, 180 mL dead space), misaligning with physiology's dual-component definition.
