Correct Answer: C

Rationale: For accurate pulmonary function tests (PFTs), it is essential to communicate that the client did not use bronchodilators within the specified timeframe, did not smoke for the required duration before the test, and can comply with different breathing maneuvers. The use of a treadmill is not part of the PFT procedure and is unrelated to the testing process. Therefore, communicating about the client's ability to run on a treadmill is not relevant to the pulmonary function tests being conducted by the respiratory therapist.

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: In this scenario, the nurse should determine if the client can safely switch to a nasal cannula during meals. It is crucial to ensure that the provider has approved this change. Oxygen is considered a medication and should be delivered continuously. Turning off the oxygen or lifting the mask while eating can lead to a decrease in the FiO2 delivered, potentially compromising the client's oxygenation status. Therefore, the best course of action is to ascertain if transitioning to a nasal cannula is appropriate for the client during the meal.

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: D

Rationale: The pulsation of the tracheostomy tube with the heartbeat may indicate a tracheoinnominate artery fistula, which can lead to life-threatening hemorrhage if the artery is breached. In this scenario, as there is no active bleeding yet, the nurse should remain with the client and have another person notify the provider immediately. If the client starts to hemorrhage, the nurse should remove the tracheostomy tube and apply pressure at the bleeding site, preparing the client for urgent surgical intervention.
