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. Provide humidified oxygen: Humidification helps prevent the drying of mucous membranes, making secretions more manageable and less tenacious. This is an acceptable method to thin

secretions in a client with a tracheostomy.

b. Prelubricate the suction catheter tip with sterile saline when suctioning the airway: While lubrication with sterile saline is a common practice during suctioning to reduce trauma to the airway, it does not directly address the tenacity of secretions.

c. Perform chest physiotherapy prior to suctioning: Chest physiotherapy is a technique used to mobilize respiratory secretions, but it may not directly address the tenacity of secretions.

d. Hyperventilate the client with 100% oxygen before suctioning the airway: Hyperventilation with 100% oxygen is not a routine practice and may lead to respiratory alkalosis. Providing

humidified oxygen is a more appropriate approach.

a. Rest in a supine position: Resting in a supine position may compromise lung expansion, and an upright position is often recommended for clients with emphysema to improve ventilation.

b. Breathe in through her nose and out through pursed lips: This technique helps maintain

positive airway pressure, preventing premature airway collapse, and can improve gas exchange in clients with emphysema.

c. Limit fluid intake throughout the day: Adequate hydration is important for maintaining

respiratory secretions in a liquefied state and is generally encouraged for clients with respiratory conditions.

d. Consume a low-protein diet: A low-protein diet is not specifically indicated for improving gas exchange in clients with emphysema. Nutrition recommendations may focus on a well-balanced diet to support overall health.
