Question 2

  1. Trying to calm an agitated patient.
  2. Failure of other methods to reduce intracranial pressure.
  3. Hypokalemia causing cardiac arrhythmias.

Answer to Question 1

ANS: B
Among critically ill patients, water retention usually is evident when rapid weight gain occurs. In addition, such patients may have a reduced hematocrit, which is also consistent with hypervole-mia due to water retention.

Answer to Question 2

ANS: C
Hyperventilation should be used temporarily after traumatic brain injury until other methods can be used to decrease elevated intracranial pressure.
