The patient's vital signs reveal a blood pressure of 187/100. The medication orders state that the health care provider should be notified before administration for diastolic blood pressure greater than 90. Based on this order, which is the nurse's best choice and should be their first action?

A. While reviewing potassium levels is important for certain antihypertensive medications like diuretics or ACE inhibitors, it is not the priority when a patient presents with a hypertensive reading. The immediate concern is the patient's elevated blood pressure and the specific parameters set by the provider. Laboratory review should follow the immediate clinical assessment and notification required by the order. B. Holding the medication is necessary because the patient's diastolic pressure (100) exceeds the provider's threshold (90). Assessing the patient for symptoms such as headache, blurred vision, or chest pain is the critical next step to determine the severity of the hypertensive state. Notifying the provider after the assessment allows the nurse to provide a complete clinical picture for further medical orders. C. Administering the medication despite the diastolic pressure being 100 would be a direct violation of the provider's order to notify them first. This could potentially harm the patient if the medication is inappropriate for the current clinical state. Nurses must strictly adhere to provided parameters to ensure patient safety and maintain legal standards of care. D. Holding the medication and calling the physician is an incomplete action because it skips the essential step of patient assessment. A nurse must never call a provider without first obtaining current assessment data, such as neurological or cardiovascular symptoms. The provider will require this information to make an informed decision regarding the patient's treatment and potential level of care.
