Correct Answer: B

Rationale: Communication between the nurse and respiratory therapist is crucial before pulmonary function tests (PFTs). It is important to inform the respiratory therapist that the client is ready for the examination. The nurse should not administer bronchodilator medication before the test as it may affect the results, and the client should not smoke for 6 to 8 hours prior to the test to ensure accurate results. Additionally, PFTs do not involve running on a treadmill; instead, the client may be required to perform specific breathing maneuvers as instructed by the respiratory therapist.

Correct Answer: C

Rationale: In a client experiencing an acute asthma attack, decreased breath sounds suggest severe airway obstruction or respiratory fatigue, indicating a worsening condition. Loud wheezing, increased respiratory rate, and a productive cough are common manifestations during an asthma attack as the airways constrict, leading to turbulent airflow causing wheezing, increased effort to breathe resulting in a higher respiratory rate, and mucus production causing a productive cough. However, decreased breath sounds signify a critical situation requiring immediate intervention.

Correct Answer: D

Rationale: A decrease in the client's respiratory rate to 10 breaths per minute, while receiving oxygen therapy for COPD, is a concerning finding that may indicate carbon dioxide retention and respiratory depression. This situation requires immediate action to prevent further complications. An oxygen saturation of 90% is within an acceptable range for COPD patients on oxygen therapy. A respiratory rate of 22 breaths per minute and reports of shortness of breath are common in clients with COPD and may not necessitate immediate action unless accompanied by other concerning symptoms.

Correct Answer: C

Rationale: After a bronchoscopy, a topical anesthetic affects the gag reflex. Therefore, the nurse should assess the client's gag reflex before providing any food or water to ensure its return. This assessment is crucial to prevent aspiration or choking risk in the client.
