LPN Fundamentals Questions
Question 1 of 5
For a client with an indwelling catheter, the nurse should obtain a sterile urine specimen by:
Correct Answer: D
Rationale: Using a needle to withdraw urine from the catheter port maintains the closed system's sterility, collecting a fresh, uncontaminated sample for testing (e.g., culture). Disconnecting the catheter risks introducing bacteria, breaking asepsis and increasing infection odds. A urinometer measures volume, not a specimen source irrelevant here. Opening the drainage bag yields old, potentially contaminated urine, unfit for sterile analysis. The port method, with sterile syringe and technique, aligns with infection control guidelines (e.g., CDC), ensuring diagnostic accuracy and patient safety, making it the standard nursing practice for this task.
