The nurse is evaluating the fluid balance of a client who was admitted yesterday with dehydration and who has been receiving IV fluids since admission. An increase in which parameter indicates to the nurse that the client is rehydrating?

Choice A reason: Providing oral sponge toothettes is the best action to take. It helps the client to maintain oral hygiene and comfort, and prevents dryness and cracking of the oral mucosa.

Choice B reason: Teaching the client that the oral mucosa must remain dry to prevent aspiration is not a correct action. The oral mucosa needs to be moist to protect it from infection and irritation. Aspiration is prevented by checking the placement of the nasogastric tube and keeping the head of the bed elevated.

Choice C reason: Turning the suction off while allowing the client to rinse his mouth with cool water is not a safe action. It may increase the risk of aspiration and interfere with the function of the nasogastric tube. The suction should only be turned off when necessary, such as during medication administration or tube feeding.

Choice D reason: Instilling 50 ml of normal saline solution into the tube and clamping the tube for one hour is not an appropriate action. It may cause fluid overload, electrolyte imbalance, and abdominal distension. The nasogastric tube should be flushed with 30 ml of water every 4 to 6 hours to maintain patency and prevent clogging.

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.
