A client arrives to the clinic with reports of progressive weakness in his lower extremities. Which of the following findings in the client's history is consistent with the client developing Guillain-Barre syndrome?

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: A facial tumor is not related to Guillain-Barre syndrome, which is an autoimmune disorder that affects the peripheral nerves.

Choice B Reason: Pregnancy is not a risk factor for Guillain-Barre syndrome, although it can occur during or after pregnancy in rare cases.

Choice C Reason: A puncture wound 3 weeks ago is unlikely to cause Guillain-Barre syndrome, which usually follows a respiratory or gastrointestinal infection.

Choice D Reason: This is the correct answer because cytomegalovirus is one of the common infections that can trigger Guillain-Barre syndrome. It can cause inflammation and damage to the myelin sheath that covers the nerves.
