A provider orders a diagnostic test for a client with a urinary tract infection. The test will determine the strain of bacteria causing the infection and determine the antibiotic that will treat the infection. The nurse knows this test is called which of the following?

A. "Pyelonephritis increases a person's risk for kidney damage." - Pyelonephritis is a bacterial infection of the renal parenchyma and renal pelvis, typically caused by the ascent of bacteria from the lower urinary tract into the kidneys. If left untreated, it can lead to kidney damage, including scarring of the renal tissue and impaired kidney function.

B. "Pyelonephritis is an infection of the lower urinary tract." - This statement is incorrect. Pyelonephritis specifically involves the upper urinary tract, affecting the kidneys. In contrast, infections of the lower urinary tract (such as cystitis) affect the bladder and urethra.

C. "Pyelonephritis often causes no symptoms in affected clients." - This statement is incorrect. Pyelonephritis typically presents with symptoms such as fever, chills, flank pain, painful urination (dysuria), and frequent urination. Clients with pyelonephritis usually experience noticeable symptoms.

D. "Pyelonephritis is most often caused by Staphylococcus saprophyticus." - This statement is incorrect. While Staphylococcus saprophyticus is a common cause of urinary tract infections, pyelonephritis is more commonly caused by gram-negative bacteria, such as Escherichia coli, which often ascend from the lower urinary tract into the kidneys.

A. Recent travel: Assessing recent travel history is relevant in understanding potential exposure to certain infections or dietary habits specific to certain regions. However, for a client admitted with renal stones, the immediate focus is on understanding factors related to their condition. While travel history might be a part of the overall assessment, it is not the priority question in this context.

B. Typical diet and fluid intake history: This is the priority question. Understanding the client's typical diet, including the types of foods they consume and their fluid intake habits, is crucial. Certain dietary factors, such as high intake of oxalate-rich foods or insufficient fluid intake, can contribute to the formation of renal stones. Gathering this information helps healthcare providers identify potential dietary factors that might have led to the stones, allowing for tailored dietary recommendations and prevention strategies.

C. Vaccination records: Vaccination records are essential for preventive healthcare, but they are not directly related to the assessment of a client admitted with renal stones. While ensuring clients are up-to-date with vaccinations is important, it is not the immediate concern in the context of renal stones.

D. Last bowel movement: Bowel movements are relevant to overall health and can provide information about gastrointestinal function. However, in the specific context of assessing a client admitted with renal stones, understanding the client's bowel movements is not the primary concern. The focus should be on factors directly related to renal stones, such as diet and fluid intake history, which can inform immediate interventions and prevention strategies.
