A patient with a Foley catheter inserted 3 days ago needs a urine sample for culture and sensitivity. What is the appropriate action for the nurse to take?
Disconnect the drainage tube from the catheter.
Withdraw urine from the closed system drainage bag.
Empty contents of the drainage bag into the specimen cup.
Attach a sterile syringe to the catheter port to withdraw urine.
The Correct Answer is D
A. Disconnect the drainage tube from the catheter:
This breaks the closed system and increases the risk of infection. Not appropriate.
B. Withdraw urine from the closed system drainage bag:
The urine in the bag is not fresh and may be contaminated, leading to inaccurate results.
C. Empty contents of the drainage bag into the specimen cup:
This is not a sterile method and would not provide a reliable culture result.
D. Attach a sterile syringe to the catheter port to withdraw urine:
This is the correct sterile technique for obtaining a sample from an indwelling catheter without contaminating the system.

Explanation
A. Betadine:
Betadine (povidone-iodine) is commonly used for cleansing the perineal area. Patients may have an allergy to iodine-based antiseptics.
B. Shellfish:
A shellfish allergy may indicate a sensitivity to iodine, which is found in Betadine. While this connection is debated, many protocols still recommend caution.
C. Latex:
Many catheters and gloves are made with latex, which can cause serious allergic reactions, including anaphylaxis.
D. Silicone:
Silicone is hypoallergenic and usually used for patients with latex allergies. True silicone allergies are rare.
E. Tape:
Tape is used to secure the catheter tubing. Some patients have adhesive allergies that can cause skin irritation or blisters.
