Under what condition do you have to notify MCP before administering nitroglycerin?

Notifying the Medical Control Physician (MCP) before administering nitroglycerin is required under the condition when you open your drug bag. This protocol is in place to ensure that all medications that are administered are accounted for and used in accordance with established guidelines, especially in situations where the drug bag is opened for the first time during a call.

When the drug bag is opened, it indicates that the paramedic is preparing to use potentially life-saving medications. This action often warrants communication with Medical Control, as it helps maintain accountability and allows the MCP to offer guidance tailored to the specific situation.

The other conditions listed, such as having personal nitroglycerin, the patient holding a prescription, or the patient's state of consciousness, do not inherently necessitate a call to MCP before administration. The key factor here is the protocol's emphasis on the importance of medication management and communication with medical authority when introducing or utilizing medications from the drug bag.
