A nurse is caring for a client who is scheduled for surgery. While the nurse is witnessing the client's signature, the client states, "I trust my doctor, but I don't understand what is meant by resecting my intestines." Which of the following actions should the nurse take?

A. "I will apply tape over frayed areas of electrical cords.":Tape should not be used on frayed electrical cords. This can be a fire hazard. Frayed cords should be replaced immediately to avoid electrical fires or shocks.

B. "I need to check my medications for expiration dates.":Checking medication expiration dates is a key part of home safety. Expired medications can be ineffective or potentially harmful, so clients should regularly check their medications and dispose of expired ones properly.

C. "I need to set my hot water heater to 140 degrees Fahrenheit.":The water heater should be set to 120 degrees Fahrenheit to prevent scalding. A temperature of 140 degrees can increase the risk of burns, especially for older adults or those with reduced sensitivity to temperature.

D. "I will use the grab bars when getting in and out of the bathtub.":Grab bars in the bathroom provide stability and prevent falls when getting in or out of the bathtub, which is a high-risk area for injury. This is a great safety measure to reduce the risk of falls.

E. "I need to have a fire escape plan with my family.":Having a fire escape plan is an essential part of home safety. It's important for all family members to know how to exit the house safely in case of an emergency, including designated meeting points.

Magnet therapy involves the use of magnets to treat various conditions, including pain relief. However, certain precautions and contraindications exist for the use of magnet therapy, especially in individuals with implanted medical devices.

Implantable cardioverter-defibrillators (ICDs) are designed to detect and treat life-threatening arrhythmias. They often contain magnetic components and sensitive circuitry that can be affected by strong magnetic fields, including those used in magnet therapy. The magnetic field from the therapy may interfere with the proper functioning of the implanted defibrillator, potentially compromising the client's safety.

Having a prescription for metoprolol, which is a beta-blocker medication used to manage conditions such as high blood pressure and heart disease, is not a contraindication for receiving magnet therapy. There is no direct interaction between metoprolol and magnet therapy.

Having an allergy to penicillin does not directly contraindicate the use of magnet therapy for pain relief. Allergies to penicillin are specific to the medication itself and do not impact the use of magnets.

A history of alcohol use disorder is not a direct contraindication for receiving magnet therapy. However, it is important to consider the overall health status and any potential interactions with other treatments or medications related to the alcohol use disorder.
