A nurse is performing a Weber test on a client who reports difficulty hearing in his left ear. The client informs the nurse that he can hear the tone louder in his left ear. Which of the following does this result indicate?

Choice A Reason: Edema is not a specific finding of a systemic infection, but rather a possible sign of fluid overload or impaired venous return. It can occur due to excessive infusion rate, heart failure, or obstruction of blood flow in or around the central line.

Choice B Reason: This is a correct choice. Purulent drainage at intravenous insertion site is a finding of a local infection that can spread systemically. It indicates bacterial invasion and inflammation of the skin and subcutaneous tissue around the catheter.

Choice C Reason: Redness at insertion site is a finding of a local infection that can spread systemically. It indicates increased blood flow and inflammation of the skin and subcutaneous tissue around the catheter.

Choice D Reason: Nausea is not a specific finding of a systemic infection, but rather a possible side effect of parenteral nutrition or a symptom of another condition. It can occur due to electrolyte imbalance, hyperglycemia, or gastrointestinal disorders.

Choice E Reason: This is a correct choice. Leukocytosis is a finding of a systemic infection that indicates increased production and release of white blood cells in response to infection. It can be detected by a blood test.

Choice F Reason: This is a correct choice. Fever is a finding of a systemic infection that indicates increased body temperature due to activation of the immune system and release of pyrogens. It can be measured by a thermometer.

Choice A Reason: This is incorrect because turning off the lights and TV and closing the door may increase the client's anxiety and confusion. The nurse should provide adequate lighting and familiar objects to help orient the client.

Choice B Reason: This is incorrect because using restraints may increase the risk of injury, infection, and psychological distress for the client. The nurse should use restraints only as a last resort and with a physician's order.

Choice C Reason: This is incorrect because asking for a sedative may not address the underlying cause of the agitation. The nurse should use non-pharmacological interventions first, such as calming music, massage, or aromatherapy.

Choice D Reason: This is correct because identifying the cause of the agitation may help resolve it. The nurse should assess for possible triggers, such as pain, hunger, thirst, infection, or environmental factors.
