A patient has been rescued from a house fire and admitted to the burn unit with deep dermal, partial thickness (second degree) burns over approximately one-third of the back and upper thighs.
The nurse begins administration of prescribed crystalloid fluids for the first 24-hours following the burn incident.
What physiological response is promoted by the administration of the fluids?

Fluid resuscitation due to capillary leaking.

Restoration of electrolyte balance.

Replacement of insensible water loss.

Extension of plasma until blood is available.

Answer and Explanation

The Correct Answer is A

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 A

Explanation

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.

A. Set up supplemental oxygen delivery B. Increase the fraction of inspired oxygen C. Gather supplies for extubation D. Place a nasogastric tube E. Offer the client ice chips F. Suggest a different ventilator mode to the provider G. Set the ventilator to give mandatory breaths

Correct Answer is ["A","C","E"]

Explanation

A. Set up supplemental oxygen delivery- This could be necessary as the client is being weaned off the ventilator and may require additional oxygen support.
C. Gather supplies for extubation- As the client is being weaned off the ventilator and the pressure support has been decreased to 0 cm H2O, extubation may be imminent.
E. Offer the client ice chips- Once extubated, the client may have a dry mouth and throat from the intubation tube. Ice chips can help soothe the throat and keep the mouth moist.

B. Increase the fraction of inspired oxygen- This action is not indicated based on the information provided. The client’s oxygen saturation is within normal range and there’s no indication that the client is experiencing difficulty breathing or hypoxia.
D. Place a nasogastric tube- There’s no indication in the scenario that the client has a need for a nasogastric tube. This procedure is typically done for clients who have difficulty swallowing or need help with feeding, neither of which is mentioned in the scenario.
F. Suggest a different ventilator mode to the provider- The client is already being successfully weaned off the ventilator, as indicated by the decreasing pressure support. There’s no indication in the scenario that a different ventilator mode is needed.
G. Set the ventilator to give mandatory breaths- This action would be counterproductive to the weaning process. The client is already on a ventilator mode with no mandatory breaths and is being successfully weaned off the ventilator.
