A nurse is collecting data on a client who has obstructive sleep apnea. Which of the following findings should the nurse expect?

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. Treatment is not needed if the client is asymptomatic.

Even asymptomatic pulmonary embolisms can lead to complications such as progression to symptomatic PE or development of chronic thromboembolic pulmonary hypertension. Therefore, treatment is necessary to prevent these complications.

B. Treatment is not needed if the pulmonary embolism is intermediate.

The severity of a pulmonary embolism is determined by various factors, including the size and location of the clot and the degree of obstruction in the pulmonary arteries. Intermediate-risk pulmonary embolisms still require treatment to prevent complications and reduce the risk of progression to a more severe or life-threatening condition.

C. Treatment is not needed if the client is hemodynamically stable.

Hemodynamic stability refers to the client's circulatory status and whether they are maintaining adequate blood flow to vital organs. While hemodynamically stable clients may not require aggressive interventions such as thrombolytic therapy or surgical embolectomy, they still require anticoagulant therapy to prevent further clot formation and reduce the risk of complications.

D. Treatment is needed for all clients who have a pulmonary embolism.

Pulmonary embolism (PE) is a serious and potentially life-threatening condition that requires prompt treatment. Regardless of the severity of symptoms or the client's hemodynamic stability, treatment is necessary to prevent complications and reduce the risk of recurrence. Treatment typically includes anticoagulant therapy to prevent further clot formation and may include additional interventions such as thrombolytic therapy or surgical interventions in certain cases.
