A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?

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. Position the client on the nonoperative side.

Positioning the client on the nonoperative side after a pneumonectomy may not be the best choice. The positioning of the client post-pneumonectomy should be based on factors such as the individual's comfort, respiratory status, and any specific instructions from the healthcare provider. Placing the client on the nonoperative side may inadvertently put pressure on the surgical site, leading to discomfort or potential complications.

B. Monitor respiratory status every 8 hr.

Monitoring respiratory status every 8 hours is not sufficient for a client post-pneumonectomy. After such a major surgical procedure, respiratory status should be closely monitored and assessed more frequently, especially in the immediate postoperative period. This frequency allows for the early detection of any signs of respiratory distress, such as decreased oxygen saturation, dyspnea, or abnormal breath sounds, as well as complications like pneumothorax or atelectasis.

C. Elevate the head of the bed to a 15° angle.

Elevating the head of the bed to a 15° angle is a general recommendation for clients postoperative to promote respiratory function and reduce the risk of aspiration. However, after a pneumonectomy, the positioning of the client may vary based on their individual condition and surgical approach. It's important to follow the healthcare provider's specific instructions regarding positioning for optimal recovery. The angle of elevation may need to be adjusted based on the client's comfort and respiratory status.

D. Encourage the client to splint the incision when coughing.

After a pneumonectomy, it's crucial to encourage the client to splint the incision when coughing. Splinting the incision with a pillow or hands helps to reduce pain and prevent strain on the surgical site, promoting healing and minimizing the risk of complications such as wound dehiscence (opening of the surgical incision).
