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. Ineffective airway clearance: This is the priority as it addresses the immediate threat to the client's respiratory status. Accumulation of thick, copious secretions can lead to airway

obstruction and respiratory distress.

b. Malnourishment: While important, addressing malnourishment is not an immediate

postoperative priority. The client may receive nutrition through alternative means until normal swallowing function is restored.

c. High risk for infection: Infection is a concern, but ensuring airway clearance takes precedence in the immediate postoperative period.

d. Impaired verbal communication: Verbal communication is important, but it is not as immediate a concern as ensuring the airway is clear to prevent respiratory compromise.

b. Paralytic ileus: Absence of bowel sounds, abdominal distention, and no passage of flatus are characteristic signs of paralytic ileus, which is a temporary impairment of bowel motility following surgery.

c. Health care-associated Clostridium difficile: Clostridium difficile infection is associated with diarrhea, abdominal pain, and fever. The absence of bowel sounds and abdominal distention is not consistent with C. difficile infection.

d. Fecal impaction: Fecal impaction is characterized by a blockage of hardened stool in the

rectum or colon, leading to difficulty passing stool. It may cause abdominal discomfort, but it does not typically present with the absence of bowel sounds and abdominal distention seen in paralytic ileus.
