A nurse is planning to reinforce teaching with a client about the need to follow a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid? (Select all that apply.)

A. This instruction is more appropriate for female clients performing perineal hygiene before providing a clean-catch urine specimen. For straight catheterization, the nurse typically performs sterile technique, including cleansing the urethral meatus with an antiseptic solution as part of the procedure. The client's perineal area may be cleansed if necessary, but the primary focus is on maintaining sterile technique during catheter insertion.
B. When performing straight catheterization, the nurse inserts a sterile catheter into the client's bladder via the urethra to obtain urine directly. The urine is collected from the catheter itself as it drains into a sterile specimen container. It's essential to avoid touching the catheter's port or allowing it to come into contact with non-sterile surfaces to prevent contamination.
C. When inserting a Foley catheter (indwelling catheter), sterile water is used to inflate the balloon at the tip of the catheter after insertion into the bladder. For straight catheterization, a balloon is not typically inflated because the catheter is removed immediately after urine is obtained. Therefore, this step is not applicable in this context.
D. It is crucial to use a sterile specimen container to collect urine obtained via straight catheterization. This ensures that the specimen remains uncontaminated and suitable for culture and sensitivity testing, which requires accurate identification of any bacteria present in the urine.

A. Butter is a dairy product, but it is not typically high in potassium. It is generally safe for clients following a low-potassium diet. Therefore, clients do not need to avoid butter specifically for its potassium content.
B. Yogurt, especially the varieties that are not low-fat or non-fat, can have a significant amount of potassium.
C Pears are generally considered low in potassium and are usually safe to include in a low-potassium diet.
D. Orange juice is a fruit juice and is naturally high in potassium. Clients should avoid or limit orange juice when following a low-potassium diet due to its potassium content.
E. Cabbage is a vegetable that is generally low in potassium. It is safe for clients following a low-potassium diet and does not need to be avoided for its potassium content.
