A nurse is teaching a group of clients about the effects of various substances. Which of the following statements by a client indicates an understanding of the teaching?

A. Encourage the client to take naps during the day: While daytime napping may help the client rest, it is unlikely to directly prevent nighttime wandering. It might even interfere with nighttime sleep, potentially increasing wandering behavior.
B. Install locks at the bottom of the exit doors: Installing locks at the bottom of exit doors is an effective safety intervention. It can prevent the client from wandering outside while still allowing caregivers to monitor and assist the client if needed.
C. Place the client's mattress on the floor: Placing the mattress on the floor might prevent injury if the client falls out of bed, but it does not address the core issue of nighttime wandering. Additional measures are needed to manage wandering safely.
D. Place rubber-backed throw rugs on tile floors: Rubber-backed throw rugs can help prevent slipping but do not directly address the issue of wandering. This intervention may be useful for fall prevention but not for preventing the client from wandering at night.

A. Has a history of gastric reflux: Gastric reflux is not a contraindication for selegiline transdermal. This medication is primarily concerned with interactions that may affect the central nervous system or blood pressure, rather than gastric issues.

B. Has a history of cholelithiasis: A history of gallstones (cholelithiasis) is not a contraindication for selegiline transdermal. This medication does not have a known direct effect on the gallbladder or bile ducts.

C. Drinks a glass of orange juice daily: There is no significant interaction between selegiline and orange juice. Clients should, however, avoid tyramine-rich foods to prevent hypertensive crises, but orange juice is not a concern in this case.

D. Takes St. John's Wort daily: This is a contraindication. Selegiline is a monoamine oxidase inhibitor (MAOI), and taking it in combination with St. John's Wort can increase the risk of serotonin syndrome, a potentially life-threatening condition. This interaction should be avoided.
