A nurse is caring for a client who has been admitted with asthma exacerbation and is experiencing increased wheezing and has an oxygen saturation of 91%. The client is scheduled for his next breathing treatment in 1hr. Which of the following actions should the nurse take?

A. Turn off the ventilator alarms before suctioning the client's airway.

This choice is incorrect because it goes against standard practice. Ventilator alarms are critical for monitoring the patient's respiratory status and detecting any issues with the ventilator or the patient's airway. Turning off alarms before suctioning can lead to missed alarms and potentially dangerous situations for the patient.

B. Provide mouth care every 10 to 12 hr with hydrogen peroxide.

This choice is incorrect because using hydrogen peroxide for mouth care is not recommended. Hydrogen peroxide can be irritating to the mucosa and may cause harm to the patient's oral tissues. Instead, gentle oral care with an appropriate solution, such as a mouthwash specifically designed for oral hygiene in ventilated patients, is preferred. Mouth care should also be provided more frequently than every 10 to 12 hours to maintain oral hygiene and prevent complications such as ventilator-associated pneumonia.

C. Place the head of the client's bed at 40° when supine.

This choice is correct. Proper positioning of the patient is crucial for optimizing ventilation and preventing complications such as aspiration and ventilator-associated pneumonia. Elevating the head of the bed to 40 degrees when the patient is in a supine position helps to minimize the risk of aspiration by promoting drainage of secretions away from the airway and improving lung expansion.

D. Reposition the client every 4 hr.

This choice is not directly related to care for clients receiving mechanical ventilation. While repositioning the patient every 4 hours is important for preventing pressure ulcers and maintaining skin integrity, it is not specific to mechanical ventilation care. However, it is still an important aspect of overall patient care, particularly for patients who are immobile or confined to bed for extended periods.

A. Encourage fluid intake of 2.5 L per day.

This is an appropriate intervention for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making them easier to cough up and clear from the airways. Adequate hydration also supports overall health and immune function. However, the nurse should consider the client's individual fluid tolerance and any comorbid conditions such as heart failure that may necessitate fluid restriction.

B. Assist the client to cough and deep breathe every 4 hr.

This intervention is also appropriate for a client with pneumonia. Coughing and deep breathing exercises help to mobilize and clear respiratory secretions, preventing complications such as atelectasis and pneumonia. However, the frequency of coughing and deep breathing may need to be tailored to the client's tolerance and respiratory status.

C. Encourage independence in completing ADLs.

While promoting independence in activities of daily living (ADLs) is generally beneficial for older adult clients, in the context of pneumonia, the priority is to ensure adequate rest and conserve energy for recovery. Depending on the severity of the illness, the client may experience fatigue and dyspnea, making it challenging to perform ADLs independently. The nurse should assess the client's functional status and provide assistance as needed while promoting independence to the extent possible.

D. Use an N-95 respirator when providing client care.

This intervention is not directly relevant to the care plan for a client with pneumonia. N-95 respirators are primarily used for respiratory protection against airborne infectious agents such as tuberculosis or certain viral infections like COVID-19. While standard precautions should be followed when caring for a client with pneumonia to prevent the spread of infection, including hand hygiene and appropriate use of personal protective equipment (PPE), an N-95 respirator is not typically indicated unless the client has a specific respiratory pathogen requiring airborne precautions.
