Prior to base contact, which action cannot be performed?

The action that cannot be performed prior to base contact is administering epinephrine for anaphylaxis at a dosage of 1 mg. In emergency medical protocols, especially in situations involving anaphylaxis, there are specific guidelines about medication administration. Typically, for adults experiencing anaphylaxis, the standard dose of epinephrine is 0.3 to 0.5 mg administered intramuscularly.

A dosage of 1 mg may be reserved for cases after base contact or in other specific situations based on a physician's direction, but it is not a standard initial treatment protocol prior to such contact. This ensures patient safety and adherence to established medical guidelines.

In contrast, administering 0.5 mg of epinephrine is an accepted action during anaphylaxis treatment and can be done prior to contacting a base. Performing CPR on an unresponsive patient is a critical lifesaving measure that must occur immediately without the need to wait for further instructions. Starting an IV line is also a standard practice that can be initiated as part of pre-hospital care for fluid resuscitation and medication administration.
