Choice A reason: Confusion and weakness are signs of dehydration and electrolyte imbalance, which can result from vomiting and diarrhea. These are serious complications that can affect the client's mental status, blood pressure, heart rate, and kidney function. The nurse should report these changes to the provider and monitor the client's vital signs and fluid status. Choice B reason: Dry oral mucosa and furrowed tongue are also signs of dehydration, but they are less severe than confusion and weakness. The nurse should report these changes to the provider as well, but they are not the most urgent ones. Choice C reason: Clear lungs bilaterally are a normal finding and do not indicate any change in the client's condition. The nurse should document this finding, but it does not require reporting to the provider. Choice D reason: A soft and non-tender abdomen is a normal finding and does not indicate any change in the client's condition. The nurse should document this finding, but it does not require reporting to the provider.
