The nurse is caring for a client who had an appendectomy 4 hours ago. Which finding requires immediate action by the nurse?

Choice A reason: An apical heart rate of 100 to 110 beats/minute is not unusual after surgery, as the client may be experiencing stress, pain, or anxiety. This finding does not require immediate action by the nurse, but should be monitored and reported if it persists or worsens. Choice B reason: Redness and edema at the incision site are expected signs of inflammation and healing after surgery. This finding does not require immediate action by the nurse, but should be assessed for signs of infection, such as pus, warmth, or foul odor. Choice C reason: A high-pitched sound heard upon inspiration, also known as stridor, is a sign of upper airway obstruction, which can be life-threatening. This finding requires immediate action by the nurse, such as administering oxygen, suctioning, or calling for help. Choice D reason: A pain rating of 8 on a scale of 1 to 10 indicates severe pain, which can affect the client's recovery and comfort. This finding requires prompt action by the nurse, such as administering analgesics, repositioning, or providing non-pharmacological interventions. However, this is not as urgent as choice C, which involves the client's airway.
