What measurement is the normal range for cardiac output in adults?

Choice A Reason:
0.9% sodium chloride is an isotonic crystalloid solution often used for fluid resuscitation. However, it is not the preferred choice for burn patients because it lacks the necessary electrolytes to replace those lost through burn injuries. While it can be used if Lactated Ringer's is unavailable, it does not provide the same balanced electrolyte composition.

Choice B Reason:
Lactated Ringer's is the preferred fluid for initial resuscitation in burn patients. It is an isotonic crystalloid solution that closely mimics the body's plasma, providing essential electrolytes such as sodium, potassium, calcium, and lactate. The lactate in the solution acts as a buffer, helping to correct metabolic acidosis, which is common in burn patients. The Parkland formula, widely used for calculating fluid needs in burn patients, specifically recommends Lactated Ringer's for the first 24 hours.

Choice C Reason:
Dextrose 5% in water is a hypotonic solution that provides free water and calories but lacks electrolytes. It is not suitable for initial fluid resuscitation in burn patients because it does not address the electrolyte imbalances and large fluid shifts that occur after a burn injury. Using this solution could lead to further complications such as hyponatremia.

Choice D Reason:
Dextrose 5% in 0.9% sodium chloride is a hypertonic solution that provides both glucose and electrolytes. However, it is not typically used for initial burn resuscitation because the high glucose content can lead to hyperglycemia, which is detrimental to burn patients. Additionally, the solution's osmolarity can exacerbate fluid shifts and worsen edema.

Choice A Reason:
Suctioning the nose is not the first action to take. Suctioning can increase intracranial pressure and potentially cause further injury. It is important to first determine the nature of the drainage before taking any invasive actions.

Choice B Reason:
Notifying the physician is important, but it should be done after confirming the nature of the drainage. Testing the fluid for glucose can help determine if it is cerebrospinal fluid (CSF), which would indicate a serious complication requiring immediate medical attention.

Choice C Reason:
Testing the drainage for glucose is the correct first action. CSF contains glucose, so a positive test would confirm that the clear fluid is CSF. This is a critical step in diagnosing a CSF leak, which can occur with basal skull fractures and requires prompt intervention to prevent infection and other complications.

Choice D Reason:
Asking the client to blow their nose is contraindicated. Blowing the nose can increase intracranial pressure and exacerbate a CSF leak. It is important to avoid any actions that could worsen the condition until the nature of the drainage is confirmed.
