Final answer:
The priority finding a nurse should report for a client post laryngectomy is a decreased respiratory rate, as it may indicate respiratory distress. Other symptoms such as shortness of breath, wheezes, or stridor should also be reported immediately, but these are not options provided in the question.
Step-by-step explanation:
Among the options provided, the priority for the nurse to report to the provider for a client 4 hours post laryngectomy is b) Decreased respiratory rate. This is a potential sign of respiratory distress which can be life-threatening, and immediate assessment and intervention are required. While the other options may be normal postoperative findings or require monitoring, a decreased respiratory rate can indicate inadequate ventilation or the development of respiratory complications such as obstruction or pneumonia. Shortness of breath, wheezes or stridor, and hoarseness are other respiratory symptoms that would also warrant immediate reporting and evaluation. A decreased respiratory rate should be prioritized over pain with swallowing (which might be anticipated post-surgery) and the presence of serosanguinous drainage (which might be a normal finding within the first few hours following a surgical procedure). The nurse should also monitor for other signs of respiratory compromise including but not limited to an increased heart rate, restlessness, cyanosis, and cough.
