The nurse is entering prescriptions for lab work in a client's electronic medical record (EMR) when the system locks up and does not restart. Which action should the nurse take first?

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:Hand hygiene is the foundation of Standard Precautions and the single most effective action to prevent transmission of infectious agents. Performing handwashing or using an alcohol‑based hand rub immediately before preparing or administering an injection removes transient microorganisms acquired from touching surfaces and protects both the client and the environment from contamination

Choice B reason:While wearing gloves during handling and disposal of contaminated sharps is recommended whenever there is potential contact with blood or body fluids, it is a secondary barrier. Reliance on gloves alone is insufficient because gloves can have micro‑perforations and are removed after use, making hand hygiene before and after glove use the priority

Choice C reason: Donning a face mask before administering the medication is not a necessary action to indicate an understanding of standard precautions. A face mask is only required when there is a risk of droplet transmission of infectious agents, such as when caring for a client with respiratory infections. It is not needed for self-administration of medications, unless the medication is aerosolized or nebulized.

Choice D reason: Removing the needle before discarding used syringes is not a safe action to indicate an understanding of standard precautions. It increases the risk of needle-stick injuries and contamination. The needle and syringe should be disposed of as a single unit in a puncture-resistant container.
