A nurse is collecting data from a client who has pulmonary tuberculosis. 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. Expiratory wheeze

Expiratory wheeze is a high-pitched, musical sound heard primarily during expiration. It occurs when air passes through narrowed airways due to bronchoconstriction, inflammation, and increased mucus production, which are characteristic features of an acute asthma exacerbation. Expiratory wheezes are commonly heard upon auscultation of the chest in individuals experiencing asthma exacerbations.

B. Pleural friction rub

Pleural friction rub is a dry, crackling or grating sound heard during both inspiration and expiration. It typically occurs when the inflamed pleural surfaces rub against each other during breathing. Pleural friction rub is associated with conditions such as pleurisy (inflammation of the pleura) or pleural effusion (accumulation of fluid in the pleural space), rather than asthma exacerbations.

C. Fine rales

Fine rales, also known as fine crackles, are brief, high-pitched, discontinuous sounds heard primarily during inspiration. They are typically associated with conditions involving the small airways and alveoli, such as pulmonary fibrosis or congestive heart failure. Fine rales are not commonly heard in asthma exacerbations.

D. Rhonchi

Rhonchi are low-pitched, snoring or rattling sounds heard primarily during expiration. They result from the passage of air through airways obstructed by thick mucus or secretions. While rhonchi may be heard in individuals experiencing asthma exacerbations, they are less characteristic than expiratory wheezes, which are more commonly associated with asthma exacerbations. Rhonchi are often associated with conditions such as chronic bronchitis or pneumonia.
