A client with a family history of cardiac disease is seeking information to control risk factors. Which lifestyle modification is most important for the nurse to encourage?

Smoking cessation.

Regular exercise.

Low-fat diet.

Stress reduction.

Answer and Explanation

The Correct Answer is A

Choice A reason: Smoking cessation is the most important lifestyle modification for the nurse to encourage. Smoking is a major risk factor for cardiac disease, as it increases blood pressure, heart rate, and oxygen demand, and damages the blood vessels and the heart muscle. Quitting smoking can reduce the risk of cardiac disease by 50% within one year.

Choice B reason: Regular exercise is a beneficial lifestyle modification for the nurse to encourage, but not the most important one. Exercise can improve cardiovascular fitness, lower blood pressure, and reduce body weight, but it does not eliminate the harmful effects of smoking on the heart and blood vessels.

Choice C reason: A low-fat diet is a helpful lifestyle modification for the nurse to encourage, but not the most important one. A low-fat diet can lower cholesterol levels and prevent atherosclerosis, but it does not reverse the damage caused by smoking to the heart and blood vessels.

Choice D reason: Stress reduction is a useful lifestyle modification for the nurse to encourage, but not the most important one. Stress can trigger the release of hormones that increase blood pressure, heart rate, and oxygen demand, and can also lead to unhealthy behaviors such as smoking, overeating, and alcohol abuse. However, stress reduction alone does not address the direct effects of smoking on the heart and blood vessels.

Correct Answer is B

Explanation

Choice A reason: Printing electronic medical record (EMR) from backup server is not the best action to take first. It may not be possible or feasible to access the backup server if the system is down. It may also delay the communication and delivery of the prescriptions to the lab.

Choice B reason: Notifying information services department of the situation is the best action to take first. It alerts the experts who can troubleshoot and fix the problem as soon as possible. It also allows the nurse to obtain guidance on how to proceed with the documentation and prescriptions.

Choice C reason: Identifying information as late entry in the record is a relevant action to take, but not the first one. It ensures the accuracy and completeness of the EMR, but it does not address the immediate issue of the system failure. The nurse may not be able to enter the information until the system is restored.

Choice D reason: Waiting for notification that the system has been rebooted is not a proactive action to take first. It may waste valuable time and compromise the client's care. The nurse should not assume that the system will be rebooted automatically or quickly.

A. Provide oral sponge toothettes so the client can cleanse and moisten his mouth. B. Teach the client that the oral mucosa must remain dry to prevent aspiration. C. Turn the suction off while allowing the client to rinse his mouth with cool water. D. Instill 50 ml of normal saline solution into the tube and clamp the tube for one hour.

Correct Answer is A

Explanation

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.
