A nurse is assessing a client and discovers the infusion pump with the client's total parenteral nutrition (TPN) solution is not infusing. The nurse should monitor the client for which of the following conditions?

Choice A reason: Excessive thirst and urination are signs of hyperglycemia, which may occur with TPN infusion, not interruption. These symptoms are not expected when TPN is halted. Choice B reason: Fever and chills suggest infection, which may occur with central line contamination but is not directly related to the interruption of TPN infusion. Choice C reason: Hypertension and crackles are signs of fluid overload, which would occur if TPN were infusing too rapidly, not when it is stopped. Choice D reason: Shakiness and diaphoresis are signs of hypoglycemia. TPN contains high concentrations of glucose, and abrupt cessation can lead to rebound hypoglycemia. Monitoring for these symptoms is critical when TPN is interrupted.
