A nurse is caring for a client who reports difficulty sleeping at home. Which of the following recommendations should the nurse provide to promote a restful home sleep environment?

Choice A rationale:

"You will need to sign a consent form before we begin the procedure." Rationale: While obtaining consent is an essential part of many medical procedures, including a bladder scan, it is not specific to the teaching related to the procedure itself. It addresses the legal and ethical aspect of the procedure but doesn't instruct the client on what to expect during the procedure.

Choice B rationale:

"I will place a gel pad directly above your pubic area before I place the probe." Rationale: This is the correct choice. Placing a gel pad above the pubic area before using the probe is an important step in ensuring proper ultrasound transmission and obtaining accurate results during a bladder scan. The gel pad helps to eliminate air gaps that could interfere with the quality of the scan.

Choice C rationale:

"You will need to hold your urine for 1 hour prior to the procedure." Rationale: Holding urine for an hour before a bladder scan might be required to ensure that the bladder is adequately filled for the scan, but it doesn't address the specific preparation related to the ultrasound procedure itself.

Choice D rationale:

"You will receive a contrast dye through an IV catheter prior to the scan." Rationale: Mentioning contrast dye and IV catheter is not relevant to a bladder scan. Contrast dye is often used in imaging studies like CT scans or angiograms, but not for a routine bladder scan. Therefore, this instruction is unrelated to the procedure in question.

Choice A rationale:

The correct answer. A piston syringe is used for wound irrigation to deliver a controlled and directed flow of fluid to clean the wound. It helps remove debris and promote healing. This choice aligns with wound irrigation best practices.

Choice B rationale:

Barrier ointment is not typically used for wound irrigation. Its purpose is to protect intact skin from moisture, friction, and other irritants, rather than to clean wounds.

Choice C rationale:

Chilled irrigation solution is not commonly used for wound irrigation. Room temperature or warm sterile saline is usually recommended for wound cleansing as cold solutions can cause discomfort and vasoconstriction.

Choice D rationale:

Sterile cotton balls are not used for wound irrigation. They may leave fibers in the wound, potentially leading to infection. Wound irrigation is usually performed using sterile syringes, solutions, and appropriate irrigation devices.
