Correct Answer: C

Rationale: In COPD, a prolonged expiratory phase is a typical finding caused by airway obstruction and air trapping. This results in difficulty expelling air from the lungs, leading to the characteristic prolonged exhalation in individuals with COPD.

Correct Answer: B

Rationale: SBAR is a structured form of communication used in healthcare settings. It stands for Situation, Background, Assessment, and Recommendation. In this scenario, informing the on-call physician about the client's allergies to morphine & codeine falls under the 'Background' component of the SBAR format, making choice B the correct answer.

Correct Answer: B

Rationale: During an acute asthma attack, the priority is to quickly relieve bronchospasm and improve breathing. Short-acting beta agonists, like albuterol, are the first-line medications as they rapidly relax bronchial muscles, providing immediate relief. Oral corticosteroids are used as adjunct therapy to reduce airway inflammation over time, while leukotriene receptor antagonists and long-acting beta agonists are not appropriate for immediate relief during an acute attack.

Correct Answer: A

Rationale: The pain of an MI is often accompanied by shortness of breath and feelings of fear or anxiety. It typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Unlike stable angina, the pain of an MI occurs without a known cause such as exertion.

Correct Answer: D

Rationale: Placing the client in a high Fowler's position is the best action in this situation as it helps to maximize lung expansion, improve breathing, and decrease the work of breathing. This position allows for better chest expansion, improving oxygenation and ventilation for the client in respiratory distress.
