The nurse is completing an assessment for a client with uncontrolled diabetes mellitus (DM) who came to the clinic reporting frequent, painful urination. Which screening test should the nurse perform first?

Rationale: A. Rapid strep test: A rapid strep test screens for streptococcal throat infections and is unrelated to urinary symptoms. It would not help identify the cause of painful urination in a client with diabetes mellitus. B. Nitazine pH strip: Nitazine pH testing is primarily used to assess amniotic fluid leakage in pregnant women, not for urinary tract infections (UTIs). It would not provide helpful information for evaluating dysuria in this situation. C. Finger stick glucose: While important for monitoring diabetes management, finger stick glucose does not directly address the acute complaint of painful urination. It would not diagnose a urinary tract infection, which is the immediate concern. D. Urine dipstick test: A urine dipstick test screens for leukocytes, nitrites, blood, and glucose in the urine and is the appropriate first screening for suspected UTI. Clients with uncontrolled diabetes are at higher risk for UTIs, and the dipstick can quickly detect infection-related changes.
