A nurse is reinforcing teaching about a low-sodium diet with a client who has hypertension. Which of the following statements by the client indicates an understanding of the instructions?

A. "Self-administer oxygen through your nasal cannula at 6 milliliters per minute during meals." is incorrect. Oxygen should not typically be increased during meals unless specifically prescribed by the provider. If the client has difficulty eating due to breathlessness, a more individualized plan is needed.

B. "Drink at least 240 milliliters of water during each meal." is incorrect. Clients with COPD may have difficulty breathing when consuming large amounts of fluids during meals. Overhydration could also worsen fluid retention in some cases. The amount of fluid should be tailored to the client’s needs and prescribed by the healthcare provider.

C. "Perform pulmonary hygiene 1 hour before meals." is correct. Pulmonary hygiene (such as postural drainage, coughing techniques, and deep breathing exercises) should be performed before meals to clear the airways and improve the ability to breathe while eating, preventing aspiration and difficulty breathing.

D. "Lie down for 30 minutes after eating." is incorrect. Lying down after eating can increase the risk of aspiration, especially in clients with COPD who may already have a compromised respiratory system. The client should be advised to remain upright after meals to prevent reflux and aspiration.

A. A negative pressure room is correct. Varicella zoster, which causes chickenpox, is an airborne virus. Therefore, airborne precautions are required, which include placing the client in a negative pressure room to prevent the spread of the virus to other areas of the facility.

B. Administering aspirin is incorrect. Aspirin should not be given to children or adolescents with varicella zoster due to the risk of Reye's syndrome. Instead, an antipyretic such as acetaminophen should be used to treat fever.

C. Contact precautions are not sufficient for varicella zoster, as the virus requires airborne precautions to prevent transmission through the air.

D. Having visitors remain at least 0.91 m (3 feet) away is incorrect. Airborne precautions require that visitors wear appropriate PPE, including respirators, and should not be restricted to 3 feet away. Ideally, visitors should wear full protective gear when entering the room.
