Advanced Cardiovascular Life Support (ACLS) Practice Exam

What is the recommended IV fluid bolus dose for a patient who achieves ROSC but is hypotensive during the post-cardiac arrest period?

1. 500 mL

2. 1 to 2 Liters

3. 3 to 4 Liters

4. 1 Liter only

The correct answer is: 1 to 2 Liters

The recommended IV fluid bolus dose for a patient who achieves Return of Spontaneous Circulation (ROSC) but is hypotensive during the post-cardiac arrest period is typically within the range of 1 to 2 liters. This volume is considered necessary to effectively manage hypotension and restore adequate circulation and perfusion to vital organs. In the context of post-cardiac arrest care, patients often present with reduced blood pressure due to various factors, including possible hypovolemia or ongoing distributive shock. Administering 1 to 2 liters of IV fluids helps to expand the intravascular volume, improving cardiac output and thereby enhancing perfusion pressure. This is particularly crucial in the early post-resuscitation phase to stabilize the patient while further evaluation and treatment can proceed. Administering a lower volume, such as 500 mL, may not adequately address significant hypotension, potentially leaving the patient unstable. On the other hand, administering excessively large volumes like 3 to 4 liters may lead to fluid overload, especially in patients with compromised cardiac function, which could exacerbate the situation. Limiting fluids to a maximum of 1 liter only might not provide sufficient support for the hypotensive state, thus underscoring
