Renal System Questions Questions
Question 1 of 5
A female patient with a suspected urinary tract infection is to provide a clean-catch urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen?
Correct Answer: B
Rationale: This answer describes the technique for obtaining a clean-catch specimen. The answer beginning, “insert a short, small, ‘mini' catheter attached to a collecting container†describes a technique that would result in a sterile specimen, but a health care provider's order for a catheterized specimen would be required. Using Betadine before obtaining the specimen might result in suppressing the growth of some bacteria. The technique described in the answer beginning “have the patient empty the bladder completely†would not result in a sterile specimen.
