Hypertension, commonly known as high blood pressure, is a prevalent health condition affecting nearly half of adults in the United States. Updated guidelines from the American College of Cardiology in 2017 define normal blood pressure as less than 120/80 mmHg. Readings consistently above this threshold indicate elevated blood pressure, with stage 1 hypertension diagnosed at 130/80 mmHg. Conversely, blood pressure below 90/60 mmHg is classified as hypotension.
Hypertension stands out as the most modifiable risk factor for cardiovascular disease. Persistent high blood pressure exerts undue stress on arterial walls, significantly increasing the likelihood of serious complications such as stroke, heart attack, and atherosclerosis.
Nurses are at the forefront of managing hypertension, a common comorbidity requiring diligent care and treatment. While certain hypertension risk factors like family history and ethnicity are non-modifiable, lifestyle factors are within patient control. Nurses play a vital role in guiding patients to recognize and modify risks such as smoking, poor dietary habits, and stress. Effective blood pressure management is crucial in preventing severe health complications and ensuring positive patient outcomes.
Nursing Process
In nursing practice, identifying appropriate nursing diagnoses for high blood pressure is the cornerstone of effective patient care. Nursing care plans then serve as roadmaps, prioritizing assessments and interventions to achieve both immediate and long-term health goals. The following sections detail essential nursing care plan examples for patients with hypertension.
Decreased Cardiac Output
Chronic hypertension and increased vascular resistance lead to vasoconstriction, potentially resulting in decreased cardiac output.
Nursing Diagnosis: Decreased Cardiac Output
Related to:
- Impaired cardiac muscle contraction
- Conditions compromising blood flow
- Structural heart impairment
- Difficulty of heart muscle to effectively pump
- Increased cardiac workload exertion
- Alteration in stroke volume
- Plaque formation in arteries
- High blood viscosity
- Atherosclerosis development
- Sedentary lifestyle choices
As evidenced by:
- Elevated central venous pressure (CVP)
- Increased pulmonary artery pressure (PAP)
- Tachycardia
- Cardiac dysrhythmias
- Ejection fraction below 40%
- Reduced oxygen saturation levels
- Presence of abnormal S3 or S4 heart sounds upon auscultation
- Chest pain (angina)
- Abnormal lung sounds detected during auscultation
- Difficulty breathing (dyspnea)
- Rapid breathing (tachypnea)
- Restlessness and anxiety
- Persistent fatigue
- Activity intolerance
- Prolonged capillary refill time
- Unexplained significant weight gain
- Edema
Expected outcomes:
- Patient will achieve and maintain blood pressure and pulse rates within acceptable parameters.
- Patient will remain free from hypertension-related complications.
- Patient will consistently adhere to prescribed lab tests, medications, and follow-up appointments for hypertension management.
Assessment:
1. Auscultate heart sounds to identify abnormalities. The presence of an S4 heart sound often indicates a stiff left ventricle, which is associated with left ventricular hypertrophy and diastolic dysfunction. Both S3 and S4 sounds can be indicative of heart failure.
2. Obtain an ECG to evaluate cardiac function. Electrocardiograms are crucial for hypertensive patients to screen for silent myocardial infarction or left ventricular hypertrophy. ECGs effectively assess heart attacks and hypertrophy of the heart muscle, common consequences of sustained high blood pressure.

3. Determine patient-specific hypertension risk factors. Diagnostic tests can identify underlying causes contributing to hypertension:
- Electrolyte panel to assess imbalances.
- Blood urea nitrogen (BUN) and creatinine levels to evaluate renal function.
- Lipid profile to check cholesterol levels.
- Hormone levels (adrenal and thyroid) to rule out endocrine disorders.
- Urinalysis for kidney function assessment.
- Imaging studies like kidney ultrasound and abdominal CT scans to examine kidneys and adrenal glands.
4. Assess for signs and symptoms of organ damage. Hypertension can often be asymptomatic, with diagnosis occurring incidentally during routine blood pressure checks. However, chronic hypertension can lead to organ damage, manifesting as:
- Stroke events
- Hypertensive encephalopathy
- Chest pain episodes
- Shortness of breath
- Heart failure progression
- Kidney function decline
- Vision disturbances
Interventions:
1. Facilitate lifelong lifestyle modifications. Hypertension, being a chronic condition, necessitates continuous monitoring and management. Encouraging regular exercise, weight management, and limiting alcohol and smoking are essential for reducing cardiovascular risk.
2. Administer prescribed beta-blockers or calcium-channel blockers. These medications are effective in rapidly controlling heart rate both at rest and during physical activity. They can be administered intravenously (IV) or orally based on patient needs.
3. Implement CPAP or supplemental oxygen during sleep if indicated. Obstructive sleep apnea treatment is critical to mitigate sympathetic nervous system stimulation, thereby reducing cardiac workload and blood pressure.
4. Monitor and progressively increase activity levels as tolerated. Regular exercise is vital for strengthening the heart and lowering blood pressure. Closely monitor patient response to activity by tracking heart rate and blood pressure changes.
5. Recommend limiting sodium intake. Excessive salt consumption is directly linked to increased cardiovascular disease and hypertension risk. Elevated sodium intake can lead to increased blood volume, reduced renin-angiotensin-aldosterone system (RAAS) response, and heightened sympathetic nervous system activity.
Deficient Knowledge
Lack of adequate understanding about hypertension can hinder patients from making informed lifestyle choices, increasing their risk of worsening health.
Nursing Diagnosis: Deficient Knowledge
Related to:
- Inadequate understanding of hypertension and its systemic effects.
- Lack of awareness regarding personal risk factors.
- Limited health literacy levels.
- Reduced interest or motivation to learn.
As evidenced by:
- Worsening blood pressure readings.
- Inability to recall provided health information.
- Non-adherence to dietary or lifestyle recommendations.
- Development of chronic conditions due to uncontrolled hypertension.
Expected outcomes:
- Patient will effectively demonstrate understanding of hypertension management through “teach-back” methods.
- Patient will accurately identify their individual risk factors for hypertension.
- Patient will articulate the purpose and importance of consistent blood pressure medication adherence, including understanding potential consequences of missed doses.
Assessment:
1. Evaluate the patient’s current understanding of hypertension. Many patients lack comprehensive knowledge about the critical role of high blood pressure in contributing to severe health conditions like stroke and heart disease. Assessing knowledge gaps is essential to tailor effective education.
2. Identify barriers to effective learning. Assess for potential cognitive, cultural, or language barriers that may impede learning. Patient perception of the problem and motivation for change significantly influence learning outcomes.
3. Assess available support systems. Patients requiring assistance with medication adherence, blood pressure monitoring, dietary modifications, or appointment follow-ups may benefit significantly from support from family or friends.
Interventions:
1. Assist patients in recognizing their personal risk factors. Educate on the distinction between modifiable (stress, diet, weight, tobacco use) and non-modifiable risk factors (age, family history, ethnicity). This helps patients focus on areas where they can make positive changes.
2. Educate on proper blood pressure monitoring techniques. Instruct patients on target blood pressure ranges and how to identify high or low readings. Have patients demonstrate using their personal BP monitor to ensure correct technique and calibration.
3. Provide consistent positive reinforcement. Avoid criticizing patients for mistakes or challenges in adhering to their treatment plan. Positively reinforce any effort to learn more or even slight improvements in health behaviors.
4. Conduct thorough medication reviews. Patients may misunderstand the purpose of their medications, leading to missed or skipped doses. Clearly explain the action, potential side effects, and rationale for each prescribed blood pressure medication, as well as frequency and interactions with other medications.
Excess Fluid Volume
Increased circulating blood volume forces the heart to work harder, leading to elevated blood pressure.
Nursing Diagnosis: Excess Fluid Volume
Related to:
- Underlying chronic conditions such as heart failure and kidney disease.
- Excessive fluid intake.
- High sodium intake contributing to fluid retention.
As evidenced by:
- Unexplained weight gain.
- Peripheral edema in extremities.
- Jugular vein distention (JVD).
- Elevated blood pressure readings.
- Tachycardia.
Expected outcomes:
- Patient will maintain stable fluid balance, demonstrated by balanced intake and output, stable baseline weight, and absence of edema.
- Patient will verbalize understanding of the importance of reducing sodium intake to manage fluid volume.
Assessment:
1. Assess for peripheral edema and weight changes. Excess fluid accumulation often manifests as swelling in extremities, particularly in the lower legs, feet, and ankles. Patients may also report sudden weight gain.
Alt text: Visible edema in a patient’s ankles and feet, a key assessment finding for excess fluid volume in nursing care related to high blood pressure.
2. Monitor relevant laboratory values. Assess for electrolyte imbalances, such as increased sodium or decreased potassium, which can result from fluid overload. Monitor renal function indicators like BUN, creatinine, and urine specific gravity to evaluate fluid retention.
3. Evaluate dietary and fluid intake patterns. An imbalanced diet high in sodium or excessive fluid intake can contribute to fluid overload and consequently increase blood pressure.
Interventions:
1. Educate on fluid and sodium restrictions. Patients with hypertension, especially those with comorbid kidney disease or heart failure, must understand and adhere to prescribed sodium and fluid restrictions to effectively manage fluid balance.
2. Administer prescribed diuretics. Diuretics may be necessary to facilitate fluid excretion if patients exhibit symptoms of fluid overload such as shortness of breath or significantly elevated blood pressure.
3. Elevate edematous extremities. Elevating swollen extremities above heart level promotes venous return and reduces edema. Frequent repositioning and pillow support can also prevent skin breakdown in edematous areas.
4. Provide education on low-sodium dietary options. Many patients are unaware of the high sodium content in processed foods, frozen meals, canned goods, and restaurant dishes. Educate patients on recommended daily sodium intake and guide them toward low-sodium food choices.
Risk for Unstable Blood Pressure
Hypertension inherently carries a risk for blood pressure instability, particularly when influenced by medical conditions or pharmacological factors.
Nursing Diagnosis: Risk for Unstable Blood Pressure
Related to:
- Structural impairment of the heart.
- Inefficient heart muscle pumping function.
- Increased cardiac workload.
- Cardiac dysrhythmias.
- Electrolyte imbalances.
- Excess fluid volume.
- Adverse effects of medications.
As evidenced by:
A risk diagnosis is characterized by the absence of current symptoms or signs, as the problem is potential rather than actual. Nursing interventions are preemptive, focused on prevention.
Expected outcomes:
- Patient will maintain blood pressure within normal limits.
- Patient will remain asymptomatic despite potential blood pressure fluctuations.
- Patient will consistently adhere to antihypertensive medication regimen to prevent unstable blood pressure episodes.
Assessment:
1. Regularly monitor patient’s blood pressure. Hypertension often presents without noticeable symptoms or warning signs. Routine blood pressure monitoring is crucial for early detection and management of hypertension.
2. Screen for secondary causes of hypertension. Conditions like renal disease, obstructive sleep apnea, thyroid disorders, and alcohol-induced hypertension require specific management strategies to effectively control blood pressure.
3. Assess caffeine consumption habits. High caffeine intake stimulates sympathetic nervous system activity, which can elevate blood pressure. Assess daily caffeine intake to identify potential contributing factors.
4. Review patient’s medication and supplement list. Numerous medications and nutritional supplements can impact blood pressure. Examples include excessive aspirin use, NSAIDs, antidepressants, decongestants, and oral contraceptives. Certain herbal remedies may also interact with antihypertensive drugs.
Interventions:
1. Minimize modifiable risk factors. Educate patients about the cardiovascular risks associated with substances like cocaine, synthetic cannabinoids, cigarette smoking, and excessive alcohol consumption, emphasizing their impact on hypertension.
2. Emphasize the importance of treatment adherence. Educate patients on the necessity of adhering to their prescribed blood pressure medication regimen. Uncontrolled hypertension is a primary cause of hypertensive crisis, defined as blood pressure exceeding 180/120 mmHg.
3. Instruct patients to report all medications and remedies. Advise patients to maintain an updated list of all medications, over-the-counter drugs, and herbal supplements, and share this list at every healthcare appointment. This enables healthcare providers to identify potential interactions that could lead to unstable blood pressure.
4. Encourage patients to maintain blood pressure logs. Regular home blood pressure readings should be recorded and reviewed at least every three months to assess treatment effectiveness and identify trends.
Sedentary Lifestyle
A sedentary lifestyle is a significant risk factor for developing hypertension. Physical inactivity contributes to a higher resting heart rate, increasing cardiac workload. Regular exercise typically results in a lower heart rate, reducing stress on the heart and arteries.
Nursing Diagnosis: Sedentary Lifestyle
Related to:
- Lack of interest in engaging in physical activity.
- Physical limitations or health conditions hindering participation in exercise.
- Insufficient knowledge regarding the benefits of exercise on blood pressure management.
As evidenced by:
- Physically deconditioned appearance.
- Overweight or obese status, or frailty.
- Activity intolerance.
- Tachycardia at rest.
- Abnormal heart rate or blood pressure response to physical activity.
Expected outcomes:
- Patient will engage in physical activity within their capabilities at least three times per week.
- Patient will report improved exercise tolerance, evidenced by reduced shortness of breath with minimal exertion and heart rate within safe limits.
- Patient will report a measurable decrease in blood pressure within one month of initiating a regular exercise program.
Assessment:
1. Establish rapport with the patient. Discussing exercise can be sensitive. Patients with sedentary lifestyles may resist behavioral changes. Building a therapeutic nurse-patient relationship is essential to understand and address resistance.
2. Assess patient history and interests. Instead of simply advising “more exercise,” explore past exercise experiences and patient interests. Tailoring exercise recommendations to enjoyable activities increases adherence.
3. Ensure patient safety for physical activity. While providers guide exercise safety, most patients benefit from some form of movement. Advise patients to avoid or modify exercises causing significant shortness of breath, fatigue, or dizziness.
Interventions:
1. Provide coaching and facilitate goal setting. Tailor exercise plans to the patient’s current activity level, strength, age, and health status. Start with achievable goals; for some, walking to the mailbox daily is a significant first step, while others may be ready for more vigorous activity. Gradual progression is key.
2. Track patient progress. Encourage patients to keep a log of their activities, exercise duration, and perceived improvements in physical responses or weight loss. Emphasize monitoring blood pressure as directed by their provider, as regular exercise often contributes to blood pressure reduction.
3. Refer to physical therapy, cardiac rehabilitation, or community programs. Patients needing structured support may benefit from physical therapy evaluations for safety guidance. Cardiac rehabilitation programs offer heart-health-specific exercise training. Local gyms or community programs may also provide accessible and affordable exercise options.
4. Educate on the benefits and necessity of exercise. Highlight that exercise benefits not only cardiovascular health but also muscle strength, coordination, and mood. Focus on positive, patient-relevant outcomes (e.g., increased energy for family activities) rather than solely on fear of illness to enhance motivation.
