The nurse is evaluating a client's symptoms, and formulates the nursing problem, "High risk for injury due to potential urinary tract infection." Which symptoms indicate the need for this nursing problem?

Rationale: A. Straining on urination and nocturia: These symptoms may indicate lower urinary tract obstruction or benign prostatic hyperplasia, but they are not specific indicators of infection or increased risk for injury from a UTI. B. Hematuria and proteinuria: Blood and protein in the urine suggest possible kidney damage or glomerular disease rather than an acute urinary tract infection, so they do not directly support the high-risk-for-injury problem. C. Azotemia and anorexia: Elevated nitrogenous wastes and decreased appetite reflect impaired renal function, which may be chronic, but they are not immediate indicators of infection risk leading to injury. D. Fever and dysuria: Fever indicates systemic response to infection, and dysuria reflects local urinary tract irritation. Together, these symptoms signal the potential for UTI, supporting the nursing problem of high risk for injury due to infection-related complications.
