A patient is admitted to the emergency room in hypertensive crisis. The nurse is aware that hypertensive urgency differs from hypertensive emergency in that:
A) The BP is always higher in a hypertensive emergency.
B) Extremely close hemodynamic monitoring is required during treatment of hypertensive emergencies.
C) Hypertensive urgency is treated with rest and tranquilizers to lower BP.
D) Hypertensive emergencies are associated with evidence of target organ damage.
Ans: D
Feedback: Hypertensive emergencies are acute, life-threatening blood pressure elevations that require prompt treatment in an intensive care setting because of the serious target organ damage that may occur. Blood pressures are extremely elevated in both urgency and emergencies; however, there is no evidence of target organ damage in hypertensive urgency. Extremely close hemodynamic monitoring of the patient's blood pressure is required in both. The medications of choice in hypertensive emergencies are those with an immediate effect such as IV vasodilators. Oral doses of fast-acting agents such as beta-adrenergic blocking agents, angiotensin-converting enzyme inhibitors, or alpha-agonists are recommended for the treatment of hypertensive urgencies.
