An elderly patient with osteoarthritis is experiencing increased pain and stiffness in their right knee.
What pathological condition should the nurse identify as the cause of these symptoms?
Degradation of joint cartilage.
A systemic inflammatory response.
An infectious process in the synovial fluid.
A decrease in bone mineral density.
The Correct Answer is A
Choice A rationale
Osteoarthritis is a joint disease in which the tissues in the joint, including the cartilage, break down over time. The degradation of joint cartilage is the primary pathological condition that leads to the symptoms of osteoarthritis, such as increased pain and stiffness.
Choice B rationale
A systemic inflammatory response is not the primary cause of osteoarthritis. While inflammation can occur in the affected joint, osteoarthritis is not a systemic inflammatory disease like rheumatoid arthritis.
Choice C rationale
An infectious process in the synovial fluid is not typically associated with osteoarthritis. Infections can lead to a different type of arthritis known as septic arthritis.
Choice D rationale
A decrease in bone mineral density is associated with osteoporosis, not osteoarthritis. In osteoarthritis, the issue is primarily with the degradation of cartilage, not a loss of bone density.

Correct Answer is A
Explanation
Choice A rationale
The administration of crystalloid fluids in the first 24 hours following a burn incident promotes fluid resuscitation due to capillary leaking. In the aftermath of a burn, there is a disruption of the normal fluid balance in the body, leading to increased capillary permeability and fluid shifts. This can result in a condition known as burn shock, characterized by decreased blood volume and inadequate tissue perfusion. The administration of crystalloid fluids helps to restore intravascular volume, improve tissue perfusion, and prevent burn shock. It also minimizes burn wound conversion and reduces the incidences of post-burn renal failure, life-threatening electrolyte disturbances, and mortality.
Choice B rationale
While restoration of electrolyte balance is an important aspect of burn management, it is not the primary physiological response promoted by the administration of crystalloid fluids in the immediate aftermath of a burn. Electrolyte imbalances in burn patients are usually a result of the systemic inflammatory response, fluid shifts, and renal dysfunction that can occur after a burn. These imbalances are typically managed through careful monitoring and specific electrolyte replacement therapies, rather than through the initial administration of crystalloid fluids.
Choice C rationale
Replacement of insensible water loss is another important aspect of burn management, but it is not the primary physiological response promoted by the administration of crystalloid fluids in the immediate aftermath of a burn. Insensible water loss occurs through evaporation from the burn wound surface and can be significant in burn patients. However, this is typically managed through the maintenance of a humidified environment and specific fluid replacement strategies, rather than through the initial administration of crystalloid fluids.
Choice D rationale
Extension of plasma until blood is available is not the primary physiological response promoted by the administration of crystalloid fluids in the immediate aftermath of a burn. While blood products may be required in the management of severe burns, particularly if there is significant blood loss or hemodynamic instability, the initial focus of fluid resuscitation in burn patients is on the administration of crystalloid solutions to restore intravascular volume and improve tissue perfusion.
Correct Answer is D
Explanation
Choice A rationale
Printing the electronic medical record (EMR) from the backup server may not be the most immediate action required. While having a backup of the EMR is important, it does not address the immediate issue of the system failure.
Choice B rationale
Waiting for notification that the system has been rebooted is a passive approach and may not be the most effective initial action. It does not address the immediate need to communicate the issue to the appropriate department.
Choice C rationale
Identifying information as a late entry in the record is a documentation practice that is used when charting is not completed in a timely manner. However, this action does not address the immediate issue of the system failure.
Choice D rationale
Notifying the information services department of the situation is the correct action. This allows the appropriate department to begin troubleshooting and resolving the issue. In the event of a system failure, the first step should be to report the issue so that it can be addressed as quickly as possible.
