A patient with an advanced neurological condition is being assessed for end-of-life decision-making. The nurse is explaining the role of an EEG in confirming brain death. Which of the following statements by the nurse is most appropriate?
"An EEG can be used alone to determine if brain activity is still present in patients who are unresponsive."
"An EEG is not needed to determine brain death as clinical signs are sufficient."
"The EEG will confirm brain death when no electrical activity is present in the brain."
"An EEG may show normal brain activity in patients who are close to brain death."
The Correct Answer is C
A. "An EEG can be used alone to determine if brain activity is still present in patients who are unresponsive.": EEG cannot be used in isolation to declare brain death because it may be affected by medications, metabolic disturbances, or hypothermia, and clinical assessment is required for a comprehensive evaluation.
B. "An EEG is not needed to determine brain death as clinical signs are sufficient.": While clinical criteria are central to brain death determination, EEG may be used as an ancillary test in certain situations, such as when confounding factors prevent full clinical assessment, to provide objective confirmation of electrical inactivity.
C. "The EEG will confirm brain death when no electrical activity is present in the brain.": EEG records cortical electrical activity, and the absence of detectable activity (electrocerebral silence) supports the diagnosis of brain death when combined with a complete clinical evaluation. This makes it a reliable confirmatory tool in specific cases.
D. "An EEG may show normal brain activity in patients who are close to brain death.": Patients nearing brain death generally exhibit severely diminished or absent cortical activity. Normal EEG findings would indicate preserved brain function and are inconsistent with imminent brain death.

Correct Answer is D
Explanation
A. Rehabilitation needs: Rehabilitation planning depends largely on burn depth, location (such as joints or face), and functional impairment rather than solely on the percentage of total body surface area (TBSA). While TBSA influences overall severity, it does not directly determine specific long-term rehabilitation strategies.
B. Type of intravenous fluids required: The type of IV fluid in the acute burn phase is generally standardized, commonly isotonic crystalloids such as lactated Ringer’s solution. TBSA estimation influences the volume of fluid required rather than the specific type of fluid administered.
C. Respiratory needs: Respiratory management is primarily influenced by the presence of inhalation injury, facial burns, or airway involvement. The rule of nines does not directly assess airway damage but estimates external burn extent.
D. Amount of body surface area burned: The rule of nines is a rapid method used to estimate the percentage of total body surface area affected by burns. This calculation guides fluid resuscitation formulas, determines burn severity classification, and influences decisions regarding transfer to specialized burn centers and overall treatment planning.
Correct Answer is ["2.0"]
Explanation
Ordered Dose: 8,000 units
Available Concentration: 4,000 units/mL
Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 8,000 ÷ 4,000
= 2.0 mL
