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.
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 B
Explanation
Choice A rationale
Roast pork is a protein source and does not contribute to fiber content. However, fresh strawberries are high in fiber and may not be suitable for a low-fiber diet.
Choice B rationale
Roasted turkey is a good source of protein and does not contribute to fiber content. Canned vegetables are typically lower in fiber than their fresh or frozen counterparts because the canning process tends to degrade some of the fiber. Therefore, this food selection indicates that the patient understands the prescribed low-fiber diet.
Choice C rationale
Both baked potatoes with skin and raw carrots are high in fiber. The skin of the potato and raw carrots contain insoluble fiber, which may not be suitable for a patient with ulcerative colitis on a low-fiber diet.
Choice D rationale
Pancakes made from refined flour can be part of a low-fiber diet. However, whole-grain cereals are high in fiber and may not be suitable for a patient with ulcerative colitis on a low-fiber diet.
Correct Answer is []
Explanation
Based on the information provided, the client is most likely experiencinganorexia nervosa.This is suggested by her significant weight loss, bradycardia, hypothermia, lanugo-type hair, and her expressed fear of gaining weight despite being underweight. However, this is a preliminary assessment and a definitive diagnosis should be made by a healthcare professional.
Actions the nurse should take to address this condition include:
- Acknowledge anxious feelings: It’s important to validate the client’s feelings and fears about food and weight gain.This can help build trust and facilitate further discussion about her health.
- Provide emotional support: Emotional support is crucial in managing eating disorders.The nurse can provide reassurance, listen empathetically, and encourage the client to express her feelings.
Parameters the nurse should monitor to assess the client’s progress include:
- Nutritional intake: Monitoring the client’s food and fluid intake can help assess her nutritional status and response to treatment.
- Weight and BMI: Regular monitoring of the client’s weight and BMI can provide objective measures of her nutritional status and response to treatment.
