Correct Answer: A

Rationale: During an acute exacerbation of asthma, the priority is to administer a short-acting beta2-agonist like Albuterol (Proventil) first. Albuterol acts quickly to dilate the airways and provide immediate relief of bronchospasm. Ipratropium (Atrovent) is an anticholinergic that can be used as an adjunct therapy. Salmeterol (Serevent) is a long-acting beta2-agonist intended for maintenance therapy, not for acute exacerbations. Fluticasone (Flovent) is a corticosteroid used for long-term asthma control and should not be the initial medication given during an acute exacerbation.

Correct Answer: A

Rationale: When a client is prescribed nicotine replacement therapy, it is crucial to emphasize that smoking while using this therapy can increase the risk of a stroke. Smoking while on nicotine replacement therapy can lead to excessive nicotine levels in the body, elevating cardiovascular risks. Therefore, the nurse should educate the client on the importance of avoiding smoking while utilizing this medication. Choices B, C, and D are not relevant to the specific teaching required for a client on nicotine replacement therapy.

Correct Answer: A

Rationale: In chronic obstructive pulmonary disease (COPD), clients often develop a barrel chest, characterized by an increased anterior-posterior diameter of the chest due to hyperinflation of the lungs. This change in chest shape is a common finding in COPD. Decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typical findings associated with COPD.

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: B

Rationale: A respiratory rate of 10 breaths per minute in a client with COPD receiving oxygen therapy may indicate respiratory depression, necessitating immediate intervention. An oxygen saturation of 91%, client reports of shortness of breath, and use of accessory muscles are expected in COPD clients.
