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 A
Explanation
A. One of the primary reasons for administering IV fluids is to correct imbalances in fluid volume or electrolyte concentrations. Examples include correcting dehydration, restoring electrolyte levels (such as sodium, potassium), and addressing fluid losses due to vomiting, diarrhea, or excessive sweating.
B. IV fluids are typically used to increase intravascular volume rather than decrease it. In conditions such as hypovolemia (low blood volume), IV fluids are administered to restore blood volume and improve circulation.
C. Third spacing refers to the abnormal accumulation of fluid in interstitial spaces, which can occur in conditions like sepsis, burns, or trauma. IV fluids are not typically administered to increase third spacing; rather, treatment aims to redistribute fluids and improve fluid balance.
D. Enteral fluids are fluids administered directly into the gastrointestinal tract (via oral or tube feeding). IV fluids are administered directly into the bloodstream and are used when enteral administration is not feasible or sufficient.
Correct Answer is ["B","C","E"]
Explanation
B. According to Medicare and The Joint Commission guidelines, the use of patient restraints requires a physician's order. The order should specify the reason for the restraint, the type of restraint, and the duration or conditions for its use.
C. Before using restraints, healthcare providers must exhaust all alternative, less restrictive measures to manage the patient's behavior or condition. This could include environmental modifications, reassurance techniques, or pharmacological interventions.
E. Restraints should be removed or released every 2 hours for reevaluation and to provide opportunities for range of motion exercises, toileting, hydration, and skin care. Restraints should not be used continuously without periodic assessment and reevaluation.
A. Punitive measures are not appropriate or effective in the use of patient restraints. Restraints should only be used for medical reasons to ensure patient safety, not as a form of punishment.
D. Inadequate staffing is not a criterion specified for using patient restraints. Restraints should not be used as a substitute for sufficient staffing levels to monitor and manage patient care.
