A female patient with a suspected urinary tract infection is to provide a clean-catch midstream urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen?
Tell the patient to clean the urethral area, void a small amount into the toilet, then void directly into a sterile container.
Have the patient empty the bladder completely; then obtain the next urine specimen that the patient is able to void.
Clean the area around the patient's meatus with a povidone-iodine (Betadine) swab and then have the patient void into a sterile specimen cup.
Insert a short sterile "mini" catheter attached to a collecting container into the urethra and bladder to obtain the specimen.
The Correct Answer is A
Choice A rationale
This method is the standard procedure for obtaining a clean-catch midstream urine specimen. The initial voiding washes away organisms near the meatus, and the midstream urine is less likely to be contaminated by bacteria from the skin or urethral area, providing a sample that more accurately represents the bacteria in the bladder.
Choice B rationale
Having the patient empty the bladder completely and then obtaining the next specimen does not ensure a clean-catch sample. This method could lead to contamination of the specimen with bacteria from the skin or urethral area.
Choice C rationale
Cleaning the area with povidone-iodine is not recommended for routine urine culture as it may kill some of the bacteria, leading to a false-negative result. The standard practice is to clean the area with mild soap and water.
Choice D rationale
Inserting a catheter is an invasive procedure and is not the first choice for obtaining a urine specimen. It is used when a patient is unable to provide a clean-catch specimen or if there are specific medical indications.

Explanation
Choice A rationale
Removing catheters as soon as they are no longer necessary can significantly reduce the risk of catheter-associated urinary tract infections (CAUTIs)¹.
Choice B rationale
While it is important for clients to urinate when they feel the urge, this practice alone is not specifically targeted at reducing the rate of urinary tract infections.
Choice C rationale
Teaching proper perineal care, including wiping from front to back, can help prevent the spread of bacteria to the urethra and reduce the risk of UTIs¹.
Choice D rationale
Continuing prescribed antibiotics until the full course is completed, even if symptoms improve, is crucial to ensure all bacteria are eliminated and to prevent antibiotic resistance³.
Choice E rationale
Adequate fluid intake helps flush bacteria from the urinary tract, which can decrease the incidence of UTIs¹.

Choice C rationale
Tomatoes are high in potassium and should be avoided by individuals with chronic kidney disease to maintain safe potassium levels¹.
Choice D rationale
Bananas are very high in potassium and are one of the most well-known foods that individuals with chronic kidney disease are advised to avoid¹.
Choice E rationale
Asparagus is lower in potassium compared to other vegetables and can be consumed in moderation by people with chronic kidney disease².
Choice F rationale
Salt substitutes often contain potassium chloride and should be avoided as they can significantly increase potassium intake, which is harmful for those with chronic kidney disease¹.
