A female client assigned to a mental health unit visits with her significant other during the evening. After the significant other leaves, the nurse notices that the client is more isolative and refuses to attend the evening group. Which response by the nurse is most therapeutic?

Choice A reason: Paper mask and gown are considered regulated medical waste, which means they are contaminated with blood, body fluids, or microorganisms that pose a potential risk of infection¹. Therefore, they should be placed in a designated biohazard bag before they are removed from the room and treated according to the facility's policies and procedures².

Choice B reason: The nurse's stethoscope is not a disposable item and does not need to be placed in a biohazard bag. However, it should be cleaned and disinfected after each use to prevent cross-contamination³.

Choice C reason: Bed linens are not classified as regulated medical waste unless they are soaked with blood or body fluids¹. They can be placed in a regular laundry bag and washed according to the facility's guidelines.

Choice D reason: Sputum specimen is a type of microbiology laboratory waste, which is regulated medical waste¹. However, it should not be placed in a biohazard bag, but in a leak-proof, puncture-resistant container that is labeled with a biohazard symbol. This ensures the safe transport and handling of the specimen.

Choice A reason: This is the correct action because the nurse should provide realistic expectations and positive reinforcement to the client. Lifestyle changes such as exercise can improve sleep quality and duration, but they may not have immediate effects. The nurse should encourage the client to continue the workout program and follow good sleep hygiene practices.

Choice B reason: This is not the best action because the nurse should focus on the client's sleep problem rather than the weight loss goal. While weight loss can be a benefit of exercise, it is not the primary reason why the client started the workout program. The nurse should not make the client feel that weight loss is the only measure of success.

Choice C reason: This is also not the best action because the nurse should not interrogate the client about the details of the exercise schedule. The nurse should respect the client's autonomy and preferences regarding physical activity. The nurse can offer suggestions or resources to help the client optimize the exercise schedule, but should not imply that the client is doing something wrong.

Choice D reason: This is another incorrect action because the nurse should not encourage the client to exercise every day or close to bedtime. Exercising too frequently or too late can interfere with the body's circadian rhythm and cause sleep problems. The nurse should advise the client to exercise at least three times a week and avoid exercising within three hours of bedtime.
