What are the nursing implementation considerations for a patient receiving nitroprusside for blood pressure?
• Encourage the patient to implement lifestyle changes, including weight loss, smoking cessation, decreased alcohol and salt in the diet, and increased exercise, to increase the effectiveness of antihypertensive therapy. • Monitor blood pressure closely during administration to evaluate for effectiveness and to ensure quick response if blood pressure falls rapidly or too much. • Monitor blood glucose and serum electrolytes to avoid potentially serious adverse effects. • Monitor the patient carefully in any situation that might lead to a drop in fluid volume (e.g., excessive sweating, vomiting, diarrhea, dehydration) to detect and treat excessive hypotension that may occur. • Provide comfort measures to help the patient tolerate drug effects, including small, frequent meals; access to bathroom facilities; safety precautions if CNS effects occur; environmental controls; appropriate skin care as needed; and analgesics as needed. • Provide thorough patient teaching, including the name of the drug, dosage prescribed, measures to avoid adverse effects, warning signs of problems, and the need for periodic monitoring and evaluation, to enhance patient knowledge about drug therapy and to promote compliance. • Offer support and encouragement to help the patient deal with the diagnosis and the drug regimen.
What are the lifespan considerations in the older adult for the use of drugs that affect blood pressure?
• Older adults frequently are prescribed one of these drugs. Older adults are more susceptible to the toxic effects of the drugs and are more likely to have underlying conditions that could interfere with drug metabolism and excretion. Renal or hepatic impairment can lead to accumulation of the drugs in the body. If renal or hepatic dysfunction is present, the dosage should be reduced and the patient monitored very closely. • The total drug regimen of the older patient should be coordinated with careful attention to interactions among drugs and alternative therapies. • Older adults need to use special caution in any situation that could lead to a fall in blood pressure, such as loss of fluids from diarrhea or vomiting, lack of fluid intake, or excessive heat with decreased sweating that comes with age. Dizziness falls, or syncope can occur if the blood pressure falls too far in these situations. The blood pressure should always be taken immediately before an antihypertensive is administered to an older adult in an institutional setting to avoid excessive lowering of blood pressure. • Older patients should be especially cautioned about sustained-release antihypertensives that cannot be cut, crushed, or chewed to avoid the potential for excessive dosing if these drugs are inappropriately cut.
