A nurse is reinforcing teaching for a client who presents with a pulmonary embolism. Which of the following information should the nurse provide?

A. Lower oxygen saturations of 93% to 94%

In an older adult client with a pneumothorax, the nurse could expect to observe lower oxygen saturations of 93% to 94%. A pneumothorax involves the accumulation of air in the pleural space, which can compress the lung and impair gas exchange, leading to hypoxemia (low blood oxygen levels). Decreased oxygen saturations would be a common finding in this condition.

B. Higher oxygen saturations of 98% to 99%

Higher oxygen saturations would be less likely in a client with a pneumothorax due to impaired gas exchange resulting from lung compression. Oxygen saturations are more likely to be lower in this condition, as indicated in option A.

C. Lower energy expenditure

While a pneumothorax may cause discomfort and dyspnea, which could potentially decrease energy expenditure due to reduced activity levels, it is not a direct physiological effect of the condition. Energy expenditure would depend on various factors, including the severity of symptoms and the individual's overall health status.

D. Increased lung capacity

A pneumothorax typically results in a decrease in lung capacity rather than an increase. The accumulation of air in the pleural space causes partial or complete collapse of the affected lung, reducing its ability to expand and decreasing overall lung capacity. Therefore, increased lung capacity would not be expected in a client with a pneumothorax.

A. Place the client in left Sims' position.

Left Sims' position is a lateral position used primarily for rectal examinations or procedures. It involves lying on the left side with the lower arm positioned behind the body and the upper knee flexed. This position is not indicated for a client post-tracheostomy. It does not provide any specific benefit for tracheostomy care and may not be comfortable or appropriate for a client recovering from tracheostomy surgery.

B. Provide humidified air.

Providing humidified air is crucial for clients post-tracheostomy to maintain moisture in the airway and prevent drying of secretions. Tracheostomy bypasses the upper airway's natural humidification mechanism, which can lead to drying of the mucous membranes and increased risk of complications such as mucus plugging and infection. Humidified air helps keep the secretions moist, facilitates their removal, promotes airway clearance, and reduces the risk of complications.

C. Clean the tracheostomy stoma with povidone-iodine.

While povidone-iodine is an antiseptic solution commonly used for skin preparation before invasive procedures, it is not typically used to clean the tracheostomy stoma, especially in the immediate postoperative period. Cleaning the stoma should be performed using sterile technique and appropriate solutions as directed by the healthcare provider. Using povidone-iodine may not be suitable for cleaning the tracheostomy stoma and could potentially irritate the area or introduce contaminants.

D. Use clean technique when providing tracheostomy suctioning.

Tracheostomy suctioning should always be performed using sterile technique to minimize the risk of introducing pathogens into the lower airway and causing infection. Clean technique, which involves washing hands and using clean gloves, is not appropriate for tracheostomy care, particularly in the immediate postoperative period when the risk of infection is higher. Sterile technique involves the use of sterile gloves, sterile suction catheters, and maintaining a sterile field to ensure the safety and cleanliness of the procedure.
