A nurse is caring for a client who is immobile. Which of the following actions is the priority for the nurse to contribute to the client's plan of care?

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.

A. Air moves in and out of a wound in the chest wall.

In an open pneumothorax, also known as a sucking chest wound, there is a communication between the pleural space and the external environment through a wound in the chest wall. This allows air to move freely in and out of the pleural cavity during respiration. As a result, there is a loss of negative pressure within the pleural space, impairing lung expansion and leading to respiratory compromise. This condition is considered a medical emergency and requires prompt intervention to prevent tension pneumothorax and respiratory failure.

B. Air cannot pass freely into the thoracic cavity through a chest wound.

In an open pneumothorax, air can pass freely into the thoracic cavity through the chest wound. This communication between the external environment and the pleural space results in air movement in and out of the wound during respiration.

C. There are no audible sounds in an open pneumothorax.

In an open pneumothorax, there may be audible sounds, such as sucking or hissing sounds, particularly during inspiration. These sounds occur due to the movement of air in and out of the chest wound and can be indicative of the condition.

D. The air is trapped when it enters the cavity.

In an open pneumothorax, the air is not trapped when it enters the pleural cavity. Instead, air moves freely in and out of the wound in the chest wall, leading to respiratory compromise and potential progression to tension pneumothorax if left untreated.
