NREMT Advanced EMT Practice Test #4

Answer - A - Administering a fluid bolus to a hypovolemic patient would increase preload. This is due to provide more volume to the venous system. Heart rate and contractility may be moderately enhanced with the increased preload. Pre-hospital fluid resuscitation is accomplished using normal saline or lactated Ringer’s. These isotonic solutions are ideal for fluid resuscitation because they tend to remain in the intravascular space for a period of time.
