Questions and Answers

What is the maximum dose of Ketamine for IV/IO administration in a Behavioral Emergency protocol, assuming the patient weighs 100 kg?

  • 400 mg
  • 300 mg (correct)
  • 500 mg
  • 200 mg

In Ventilation Management, what is the most appropriate IV/IO dose of Ketamine for a 20 kg child, aiming for induction?

  • 15 mg
  • 10 mg
  • 20 mg (correct)
  • 40 mg

If a patient exhibits a systolic blood pressure consistently below 100 mmHg, would Ketamine be an appropriate drug to administer?

  • No, alternative pain management options should be considered. (correct)
  • Yes, but only with careful monitoring and adjustments to the dose.
  • No, Ketamine is a vasodilator and could further decrease blood pressure.
  • Yes, Ketamine is generally safe for patients with low blood pressure.
