A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?

A. Inspiratory stridor - This is associated with upper airway obstruction and is not indicative of a pneumothorax.

B. Expiratory wheeze - Wheezing is commonly associated with lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD), not pneumothorax.

C. Coarse crackles - Coarse crackles are typically heard in conditions such as pneumonia or pulmonary edema, not pneumothorax.

D. Absence of breath sounds - This is a key manifestation of a pneumothorax. The air in the pleural space can prevent the lung from fully expanding, leading to the absence of breath sounds on the affected side.

a. Instruct the client to tilt her head back when she swallows: This action is not recommended, as it increases the risk of aspiration. Tilted head positions can lead to improper bolus control and

swallowing difficulties.

b. Add thickener to fluids: This is an appropriate intervention for a client with dysphagia, as thickened fluids are easier to control during swallowing and reduce the risk of aspiration.

c. Place food on the left side of the client's mouth: This action may not directly address the risk of aspiration associated with dysphagia and left-sided weakness.

d. Serve food at room temperature: While serving food at room temperature may be preferred for some clients, it does not directly address the safety concerns associated with dysphagia and left- sided weakness.
