A nurse is teaching a group of nursing students about pyelonephritis. Which of the following statements should the nurse include in the teaching?

A. Increased urinary output: Phenazopyridine (Pyridium) does not directly impact urinary output. Its primary function is to provide relief from urinary pain, burning, and discomfort associated with urinary tract infections (UTIs) or other urinary conditions. It does not affect the amount of urine a person produces.

B. Decreased WBC's: Phenazopyridine does not directly influence white blood cell count (WBCs). WBC count is an indicator of the body's immune response and is typically used to assess the presence of infection. Phenazopyridine provides symptomatic relief but does not affect the underlying infection or the body's immune response to it.

C. Increased uric acid: Phenazopyridine does not affect uric acid levels. Uric acid is a waste product that is excreted by the kidneys. Elevated uric acid levels can be associated with conditions like gout, but Phenazopyridine does not have any direct impact on these levels.

D. Decreased bladder pain/spasms: Phenazopyridine is intended to relieve symptoms such as bladder pain, spasms, burning sensation, and discomfort experienced during urination. Therefore, the effectiveness of Phenazopyridine is indicated by a reduction in these symptoms. If the patient reports a decrease in bladder pain and spasms, it suggests that the medication is working to alleviate the discomfort associated with urinary tract issues.

A. Venous thromboembolism (VTE) - While VTE can cause leg pain and swelling, the presence of fever, chills, and localized trauma history in this scenario points more toward cellulitis.

B. Cellulitis
The client's symptoms, including pain, swelling, fever, chills, and sweating, are indicative of cellulitis, which is a bacterial skin infection. The history of trauma to the leg (hitting the leg on the car door) could have introduced bacteria into the skin, leading to the infection. The client's diabetes mellitus type 2 also increases the risk of developing skin infections due to impaired immune function and circulation. Cellulitis often presents with localized pain, swelling, warmth, redness, and systemic symptoms like fever and chills. Immediate medical evaluation and appropriate antibiotic treatment are necessary for cellulitis.

C. Arterial insufficiency - Arterial insufficiency typically presents with symptoms like intermittent claudication, rest pain, and non-healing wounds due to poor circulation. The symptoms described in the scenario are more consistent with an acute infection (cellulitis) rather than chronic arterial insufficiency.

D. Thrombocytopenia - Thrombocytopenia is a condition characterized by low platelet count and does not directly cause localized pain, swelling, and redness in the leg as described in the scenario.
