Hypertensive Emergency is severe hypertension (high blood pressure) with acute impairment of an organ system (especially the central nervous system, cardiovascular system and/or the renal system) and the possibility of irreversible organ-damage. In case of a hypertensive emergency, the blood pressure should be lowered aggressively over minutes to hours with an antihypertensive agent.
Several classes of antihypertensive agents are recommended and the choice for the antihypertensive agent depends on the cause for the hypertensive crisis, the severity of elevated blood pressure and the patient’s usual blood pressure before the hypertensive crisis. In most cases, the administration of an intravenous sodium nitroprusside injection which has an almost immediate antihypertensive effect is suitable but in many cases not readily available. In less urgent cases, oral agents like captopril, clonidine, labetalol, prazosin, which all have a delayed onset of action by several minutes compared to sodium nitroprusside, can also be used.

Decreased Cardiac Output
NDx: Decreased cardiac output r/t altered stroke volume secondary to hypertensive emergency
Hypertension is defined as a condition wherein there is an increase in BP beyond the normal range. Hypertensive emergency is used for BPs above 160/100mmHg. With hypertension, the blood vessels constrict. When blood vessels are constricted, there is a decrease in blood volume, decrease in cardiac output and increase in BP as blood passes through the narrowed lumen of the vessels.
|Assessment||Objectives||Nursing Interventions||Rationale||Expected Outcome|
|Short Term:After 6 hours of NI, the pt will manifest hemodynamic stability (BP, CO, UO, PR) pt shall also verbalize understanding of the disease process & risk factors
After 4 days of NI, the pt will participate in activities that decrease blood pressure
||The pt shall have manifested hemodynamic stability (BP, CO, UO, PR) pt shall have also verbalized understanding of the disease process & risk factors.The pt shall have participated in activities that decrease blood pressure|
