The nurse is providing care for an elderly client who has cognitive changes. The nurse recognizes that which statement regarding dementia and delirium is true?
Both are accompanied by changes in level of consciousness.
Memory is affected equally in both diseases.
Only delirium is reversible.
The progression of both diseases is slow.
The Correct Answer is C
C. Delirium is often reversible once the underlying cause is identified and treated (e.g., correcting electrolyte imbalances, managing infections, discontinuing medications contributing to delirium). With appropriate intervention, the mental status can improve, and the individual can return to their baseline cognitive function.
A. Dementia, on the other hand, is a chronic, progressive syndrome that primarily affects memory, thinking, behavior, and the ability to perform everyday activities. It does not typically cause acute changes in consciousness.
B. Memory impairment is a hallmark feature of dementia, especially in the early stages. In contrast, delirium primarily affects attention, awareness, and cognition acutely, with memory impairment being variable and not a defining feature.
D. Delirium develops rapidly, often over hours to days, in response to an acute medical condition, medication change, or other factors. It is characterized by a fluctuating course and can resolve once the underlying cause is managed.

Correct Answer is C
Explanation
C. Before administering a feeding through a gastrostomy tube, it is essential to verify that the tube is patent (open and unobstructed). Tube patency ensures that the feeding formula or medication can flow freely into the stomach or intestines without encountering any blockages or resistance. The nurse should flush the tube with water to check for patency and ensure proper functioning before initiating the feeding.
A. Vital signs are typically assessed for overall health monitoring and to detect any immediate changes in the client's condition. However, they are not specifically required before every feeding via gastrostomy tube unless there are specific concerns about the client's stability.
B. This option is not typically necessary before administering a feeding through a gastrostomy tube. In fact, elevating the head of the bed to at least 30 to 45 degrees is often recommended during and after feeding to minimize the risk of aspiration. This position helps to promote digestion and reduce the likelihood of reflux or regurgitation of the feeding.
D. Assisting the client to a prone (face-down) position is unnecessary and potentially unsafe before administering a feeding through a gastrostomy tube. The recommended position for feeding via gastrostomy tube is typically semi-Fowler's position (elevated head of the bed), which helps prevent aspiration and facilitates digestion.
Correct Answer is D
Explanation
D. Processed foods, including canned soups, snacks, and pre-packaged meals, are major sources of dietary sodium. By avoiding processed foods, the client can significantly reduce their sodium intake and better adhere to a low-sodium diet.
A. While organic vegetables may be a healthy choice for other reasons (such as reducing pesticide exposure), canned vegetables, whether organic or not, often contain added sodium for preservation. Therefore, selecting canned vegetables, even if organic, may not align with the goal of reducing sodium intake.
B. This statement suggests an understanding of choosing lower-sodium options for sandwiches. Lean deli meats, such as turkey or chicken breast, typically contain less sodium compared to processed or cured meats like salami or bologna. Opting for lean deli meats supports the client's effort to reduce sodium intake as part of a low-sodium diet.
C. This statement indicates a misunderstanding of a low-sodium diet. Smoked meats, such as smoked ham or bacon, are often high in sodium due to the curing and smoking process. Including smoked meat products in the diet would likely increase sodium intake, which contradicts the goal of reducing sodium.
