A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

Choice A rationale:

Storing unused patches in the refrigerator is not necessary for transdermal scopolamine patches. Refrigeration is not a requirement for their storage.

Choice B rationale:

Applying the patch prior to traveling is the correct choice. Transdermal scopolamine patches are used to prevent motion sickness. Applying the patch before the journey allows the medication to be absorbed before exposure to motion, ensuring its effectiveness during travel.

Choice C rationale:

Placing the patch on the upper arm is a specific and correct instruction for applying transdermal scopolamine patches. The patch should be placed on a clean, dry, and hairless area of the skin, preferably behind the ear or on the upper arm.

Choice D rationale:

Replacing a dislodged patch onto the same location is incorrect. If the patch becomes dislodged, it should be replaced with a new patch on a different, clean, and dry area of the skin. Reapplying a dislodged patch to the same spot may result in uneven absorption and reduced effectiveness.

Choice A rationale:

Looping the tubing so that it is lower than the collection bag creates a dependent loop where urine can pool, increasing the risk of UTI. This practice should be avoided as it can lead to bacterial contamination and subsequent infections.

Choice B rationale:

Keeping the urinary bag at bladder level when ambulating helps maintain a continuous flow of urine into the collection bag without creating dependent loops. This practice minimizes the risk of bacterial contamination and reduces the chances of acquiring a UTI.

Choice C rationale:

Obtaining urinary samples by disconnecting the tubing connections is not recommended. This procedure can introduce bacteria into the urinary system, increasing the risk of UTI. Sterile techniques, such as using a catheter port for sampling, should be followed to minimize the risk of infection.

Choice D rationale:

Securing the catheter to the client's thigh is essential to prevent tension and pulling on the catheter, which can cause trauma to the urethra. However, securing the catheter alone does not minimize the risk of UTI. Proper hygiene, closed drainage system, and maintaining a continuous flow of urine into the collection bag are key factors in preventing UTIs in clients with indwelling urinary catheters.
