What action should be taken when administering a Calcium Channel Blocker if the systolic blood pressure is 100 or lower?

When administering a Calcium Channel Blocker, it is crucial to assess the patient's blood pressure prior to administration. If the systolic blood pressure is 100 or lower, holding the medication is essential because Calcium Channel Blockers can cause further vasodilation and decrease the heart rate, potentially leading to hypotension.

The rationale behind notifying the physician is to assess the patient's condition and determine whether adjustments or alternative treatment options are necessary. This action ensures patient safety and allows for appropriate management of their blood pressure and potential cardiovascular issues. Monitoring is fundamental, as giving the medication could result in serious complications due to already low blood pressure.
