Correct Answer is B
Explanation
A. Protective prone: The prone position (lying on the stomach) does not allow easy enema administration and is not recommended.
B. Left lateral recumbent: The left lateral position allows gravity to assist with enema administration and helps the fluid move efficiently through the colon.
C. High Fowler's: Sitting upright does not promote proper enema flow, making it ineffective.
D. Dorsal recumbent: Lying on the back does not facilitate enema administration effectively.
Correct Answer is B
Explanation
A. Obtain daily urine specimens by opening the collection drainage system: Opening the drainage system increases the risk of introducing bacteria into the catheter, which can lead to infection.
B. Keep the urine collection bag below the level of the bladder at all times: Keeping the bag below the bladder prevents urine from back flowing into the bladder, which reduces the risk of infection.
C. Retract the foreskin to clean the catheter tubing and meatus outward, leaving the foreskin retracted: While the foreskin should be retracted for cleaning, it must always be returned to its normal position to prevent paraphimosis, a condition where the foreskin becomes trapped and restricts blood flow.
D. Change the indwelling catheter at least every one week: Routine catheter changes are not recommended unless there is an indication such as obstruction or infection. Unnecessary changes increase infection risk.
