Correct Answer: B

Rationale: To ensure the PFTs are accurate, the therapist needs to know that no bronchodilators have been administered in the past 4 to 6 hours, the client did not smoke within 6 to 8 hours prior to the test and the client can follow basic commands, including different breathing maneuvers. The respiratory therapist can perform PFTs at the bedside. A treadmill is not used for this test.

Correct Answer: B

Rationale: To ensure effective use of albuterol via a metered-dose inhaler, the nurse should have the client hold their breath for 10 seconds after inhaling the medication. This action allows the medication to reach deeper into the airways. Inhaling slowly and deeply, not quickly, is recommended for optimal drug delivery. Exhaling immediately after inhaling the medication would expel it before it can take effect. It's essential for the client to follow the prescribed regimen of medication usage, not just using the inhaler when symptoms are present.

Correct Answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.

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: A

Rationale: The priority action for the nurse is to assess the client's lung sounds to check for signs of aspiration, which can compromise the client's oxygenation. This is crucial to ensure the client's immediate safety and respiratory status. Once the client has been assessed, the nurse can then consider consulting with the registered dietitian regarding appropriate thickened liquids for future meals. Assigning a different UAP or reporting the UAP to the manager may be necessary steps but not the immediate priority in this situation.
