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: The correct answer is A. Using the peak flow meter every morning is crucial for monitoring asthma control and making timely treatment adjustments. While using the meter when feeling short of breath or before using an inhaler can also be beneficial, the daily morning routine helps in consistent management of asthma symptoms.

Correct Answer: C

Rationale: Suprasternal retraction during inhalation suggests the client is using accessory muscles due to difficulty in moving air into the respiratory passages caused by airway narrowing. The presence of bilateral wheezing and decreased pulse oxygen saturation further support airway narrowing. In this situation, immediate intervention is necessary to improve oxygenation. Administering oxygen to maintain saturations above 94% is crucial to support oxygenation. While administering a rescue inhaler may be warranted, the priority in this scenario is ensuring adequate oxygenation to address the respiratory distress.

Correct Answer: B

Rationale: Cyanosis unresponsive to oxygen therapy suggests methemoglobinemia, an adverse effect of benzocaine spray. Methemoglobinemia can lead to death if not managed promptly. The nurse should notify the Rapid Response Team to provide immediate advanced care. Administering albuterol would not address the underlying cause of cyanosis. Assessing peripheral pulses and obtaining cultures are not the priority as they do not directly address the urgent need to manage methemoglobinemia.

Correct Answer: B

Rationale: When a client is using oxygen, there is a risk for impaired skin integrity due to pressure from tubing. Intact skin behind the ears suggests that the client is not experiencing skin breakdown, meeting the goals for this diagnosis. The client's nutrition, understanding of oxygen therapy, and weight stability are important but do not directly relate to the priority diagnosis of skin integrity in this context.
