When initiating oxygen per mask to a client who is short of breath, the nurse hears a loud hissing sound after inserting the flowmeter into the wall outlet. Which should the nurse do next?

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.

Choice A reason: Positive external places are images of pleasant and relaxing environments that can distract the client from the pain and induce a sense of calmness and well-being. Examples of positive external places are a beach, a garden, or a mountain.

Choice B reason: Emotional reflection is a process of exploring and expressing one's feelings and emotions. It may be helpful for some clients to cope with stress and anxiety, but it is not the best focus for guided imagery for chronic pain. Emotional reflection may trigger negative emotions or memories that can worsen the pain perception.

Choice C reason: Motivational phrases are statements that encourage and inspire the client to achieve a goal or overcome a challenge. They may be useful for some clients to boost their self-confidence and self-efficacy, but they are not the best focus for guided imagery for chronic pain. Motivational phrases may not be effective in reducing the pain intensity or duration.

Choice D reason: Tranquil sounds are noises that create a soothing and peaceful atmosphere. They may be helpful for some clients to relax and fall asleep, but they are not the best focus for guided imagery for chronic pain. Tranquil sounds may not be enough to divert the client's attention from the pain or create a positive emotional state.
