A nurse is teaching about food choices to a client who has chronic kidney disease and must limit potassium intake. Which of the following choices should the nurse recommend as containing the least potassium?

Choice A reason: A client with diabetes mellitus presenting with acute ketoacidosis does not necessarily require a private room unless there are other infection control concerns. Acute ketoacidosis is a metabolic complication of diabetes that can be managed in a general ward setting with appropriate medical care and monitoring.

Choice B reason: An older adult client admitted with aspiration pneumonia would benefit from a private room if the pneumonia is caused by an infectious agent that requires droplet or airborne precautions. However, aspiration pneumonia is often a result of inhaling food, stomach acid, or saliva into the lungs, and not always infectious.

Choice C reason: A client with a compound fracture of the right femur would require a private room if there is an associated risk of infection due to the open nature of the injury. However, standard precautions and wound care can often be managed in a semi-private or general ward setting unless there are specific infection control issues.

Choice D reason: A client reporting fever, night sweats, and cough for 2 days may be exhibiting symptoms of a communicable disease such as tuberculosis. This client would require a private room with airborne precautions to prevent the spread of infection to other patients and healthcare workers.

Choice A reason: The fluctuation of fluid in the water-seal chamber does not necessarily mean that the lung is fully re-expanded. The water-seal chamber's fluid level fluctuates with the client's breathing because it reflects the changes in intrathoracic pressure.

Choice B reason: The statement "Your breathing pattern causes this" is correct. The fluctuation, also known as tidaling, in the water-seal chamber is normal and occurs in response to the client's breathing. When the client inhales, negative pressure in the chest cavity causes the fluid level to rise, and when the client exhales, the pressure becomes positive, causing the fluid level to fall.

Choice C reason: Suction pressure that is too high can cause continuous bubbling in the suction control chamber but does not directly cause the fluid in the water-seal chamber to rise and fall. The suction control chamber's bubbling should be steady and gentle when the suction is set correctly.

Choice D reason: Continuous bubbling in the water-seal chamber may indicate an air leak, which is a problem that needs to be addressed. However, normal fluctuation with breathing is not indicative of an air leak.
