Hypertension, commonly known as high blood pressure, is a prevalent health concern 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 above this are considered elevated, 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. It imposes undue stress on arterial walls, significantly increasing the likelihood of serious conditions such as stroke, heart attack, and atherosclerosis. Effective management of hypertension is crucial in preventing these severe health outcomes.
As healthcare professionals, particularly nurses, play a vital role in patient care, understanding Nursing Diagnosis Hypertension Nanda is paramount for delivering optimal care. This guide will delve into relevant nursing diagnoses, providing a framework for developing effective care plans for patients with hypertension.
Nursing Process and Hypertension Management
In the realm of nursing, the nursing process serves as a systematic approach to patient care. For patients with hypertension, this process begins with identifying appropriate nursing diagnoses. These diagnoses, often aligned with NANDA-I (North American Nursing Diagnosis Association International), provide a standardized language for describing patient health problems that nurses can address.
While some hypertension risk factors like family history and ethnicity are non-modifiable, lifestyle behaviors are within a patient’s control. Nurses are instrumental in helping patients recognize modifiable risk factors such as smoking, unhealthy dietary patterns, and stress. Education on risk reduction and blood pressure control is essential to prevent complications and improve patient outcomes.
Nursing Care Plans for Hypertension
Once nursing diagnoses are established for hypertension, nursing care plans become essential tools. They prioritize assessments and interventions, guiding both short-term and long-term care goals. The following sections present examples of nursing care plans for common nursing diagnoses associated with hypertension.
Decreased Cardiac Output
Chronic hypertension and increased vascular resistance can lead to vasoconstriction, ultimately resulting in decreased cardiac output.
Nursing Diagnosis: Decreased Cardiac Output
Related Factors:
- Impaired cardiac muscle contraction
- Conditions compromising blood flow
- Structural heart impairment
- Myocardial pumping difficulty
- Increased cardiac workload
- Altered stroke volume
- Plaque formation
- Increased blood viscosity
- Atherosclerosis
- Sedentary lifestyle
As Evidenced By:
- Elevated central venous pressure (CVP)
- Elevated pulmonary artery pressure (PAP)
- Tachycardia
- Dysrhythmias
- Ejection fraction below 40%
- Decreased oxygen saturation
- Presence of S3 or S4 heart sounds
- Chest pain (angina)
- Abnormal lung sounds
- Dyspnea (difficulty breathing)
- Tachypnea (rapid breathing)
- Restlessness
- Fatigue
- Activity intolerance
- Prolonged capillary refill time
- Significant weight gain
- Edema
Expected Outcomes:
- Patient will maintain blood pressure and pulse within acceptable parameters.
- Patient will remain free from hypertension-related complications.
- Patient will adhere to prescribed medications, lab tests, and follow-up appointments for hypertension management.
Nursing Assessments:
1. Auscultate heart sounds.
The presence of an S4 heart sound can indicate left ventricular hypertrophy and diastolic dysfunction due to a stiff left ventricle. Both S3 and S4 sounds are indicative of potential heart failure.
2. Obtain an ECG.
Electrocardiograms are crucial for hypertensive patients to detect silent myocardial infarction or left ventricular hypertrophy. ECGs are valuable in assessing heart attacks and hypertrophy of the heart muscle, both consequences of high blood pressure.
3. Identify hypertension risk factors.
Diagnostic tests are essential to investigate potential underlying causes of hypertension:
- Electrolyte levels
- Blood urea nitrogen (BUN) and creatinine for renal function
- Lipid profile for cholesterol assessment
- Hormone levels (adrenal and thyroid)
- Urinalysis
- Imaging studies like kidney ultrasound and abdominal CT to evaluate kidneys and adrenal glands.
4. Monitor for signs and symptoms.
Hypertension can often be asymptomatic, discovered incidentally during routine blood pressure measurement. Chronic hypertension can lead to organ damage, manifesting as:
- Stroke
- Hypertensive encephalopathy
- Chest pain
- Shortness of breath
- Heart failure
- Kidney dysfunction
- Vision disturbances
Nursing Interventions:
1. Promote lifelong lifestyle modifications.
Hypertension is a chronic condition requiring continuous management. Emphasize the importance of exercise, weight management, and limiting alcohol and smoking to minimize cardiovascular risk.
2. Administer prescribed medications.
Beta-blockers and calcium channel blockers are often prescribed to control heart rate effectively at rest and during activity. These can be administered intravenously (IV) or orally.
3. Implement CPAP or supplemental oxygen if needed.
Obstructive sleep apnea management is crucial to reduce sympathetic nervous system stimulation, thereby decreasing cardiac workload and blood pressure.
4. Monitor and progressively increase activity.
Regular exercise is vital for strengthening the heart and lowering blood pressure. Closely monitor the patient’s heart rate and blood pressure response to activity.
5. Restrict sodium intake.
Excessive salt consumption is linked to increased cardiovascular disease and hypertension. High salt intake leads to increased fluid volume, reduced RAAS response, and heightened sympathetic nervous system activity.
Deficient Knowledge
Lack of understanding about hypertension can hinder patients from making informed lifestyle choices, increasing their risk of worsening health conditions.
Nursing Diagnosis: Deficient Knowledge
Related Factors:
- Lack of understanding of hypertension and its systemic effects
- Inadequate knowledge of risk factors
- Limited health literacy
- Lack of interest or motivation in learning
As Evidenced By:
- Elevated or worsening blood pressure readings
- Inability to recall provided information
- Non-adherence to dietary or lifestyle recommendations
- Development of chronic conditions due to uncontrolled hypertension
Expected Outcomes:
- Patient will demonstrate understanding of hypertension management through “teach-back” methods.
- Patient will identify personal risk factors for hypertension.
- Patient will articulate the purpose and importance of adherence to blood pressure medications.
Nursing Assessments:
1. Evaluate patient’s understanding of hypertension.
Many patients lack a comprehensive understanding of hypertension’s role in contributing to other diseases and increasing the risk of stroke and heart disease. Assess knowledge gaps to tailor education effectively.
2. Identify barriers to learning.
Assess for cognitive, cultural, or language barriers that may impede learning. Patient perception of the problem and motivation for change are also critical factors. Learning is unlikely to occur if the patient is not ready or does not perceive a need to learn.
3. Assess support systems.
Patients needing assistance with medication adherence, blood pressure monitoring, dietary modifications, or appointment follow-ups may require support from family or friends to manage their condition effectively.
Nursing Interventions:
1. Help patients identify personal risk factors.
Educate patients about modifiable (stress, diet, weight, tobacco use) versus non-modifiable risk factors (age, family history, ethnicity). This helps patients pinpoint areas for potential improvement.
2. Instruct on blood pressure monitoring techniques.
Educate patients on target blood pressure ranges and what constitutes high or low readings. Observe patient technique using their home BP monitor to ensure accurate readings.
3. Provide positive reinforcement and encouragement.
Avoid criticizing patients for errors or difficulties in adhering to their treatment plan. Positively reinforce any effort to learn and even minor improvements.
4. Thoroughly review medications.
Patients may not fully grasp the purpose of their medications, leading to missed doses. Review the action, side effects, and rationale for each blood pressure medication, as well as dosage frequency and potential drug interactions.
Excess Fluid Volume
Increased circulating blood volume places extra strain on the heart, leading to elevated blood pressure.
Nursing Diagnosis: Excess Fluid Volume
Related Factors:
- Chronic conditions: heart failure, kidney disease
- Excessive fluid intake
- High sodium intake
As Evidenced By:
- Weight gain
- Edema in extremities
- Jugular vein distention (JVD)
- Elevated blood pressure
- Tachycardia
Expected Outcomes:
- Patient will maintain stable fluid balance, demonstrated by balanced intake and output, baseline weight, and absence of edema.
- Patient will verbalize the importance of sodium restriction.
Nursing Assessments:
1. Assess for peripheral edema and weight changes.
Excess fluid typically manifests as swelling in the extremities, particularly in the lower legs, feet, and ankles. Patients may also experience rapid weight gain.
2. Monitor relevant lab values.
Monitor for electrolyte imbalances, such as elevated sodium or decreased potassium, which can be caused by fluid overload. Assess renal function indicators like BUN, creatinine, and urine specific gravity for signs of fluid retention.
3. Evaluate dietary and fluid intake.
An imbalanced diet high in sodium or excessive fluid intake can contribute to fluid overload and increased blood pressure.
Nursing Interventions:
1. Educate on fluid and sodium restrictions.
Patients with hypertension, especially those with co-existing kidney disease or heart failure, need to understand the importance of sodium and fluid intake management due to the complexities of fluid balance regulation.
2. Administer diuretics as prescribed.
Diuretics may be necessary to eliminate excess fluid in patients exhibiting symptoms like shortness of breath or significantly elevated blood pressure.
3. Elevate edematous extremities.
Elevating swollen extremities above heart level aids circulation. Frequent repositioning and pillow support can also prevent skin breakdown.
4. Counsel on low-sodium food choices.
Patients are often unaware of the high sodium content in processed foods. Educate on daily recommended sodium intake, emphasizing limiting processed foods and choosing low-sodium alternatives like fresh, whole foods.
Risk for Unstable Blood Pressure
Hypertension inherently carries a risk for unstable blood pressure, especially when medical or pharmacological factors contribute to BP fluctuations.
Nursing Diagnosis: Risk for Unstable Blood Pressure
Related Factors:
- Structural heart impairment
- Myocardial pumping difficulty
- Increased cardiac workload
- Dysrhythmias
- Electrolyte imbalances
- Excess fluid volume
- Medication side effects
As Evidenced By:
Risk diagnoses are not evidenced by current signs and symptoms, as the problem is preventative. Interventions focus on preventing the potential issue.
Expected Outcomes:
- Patient will maintain blood pressure within normal limits.
- Patient will remain asymptomatic despite potential blood pressure fluctuations.
- Patient will adhere to antihypertensive medications to prevent unstable blood pressure.
Nursing Assessments:
1. Regularly monitor blood pressure.
Hypertension is often asymptomatic. Routine blood pressure monitoring is critical for early detection and prevention of complications.
2. Screen for secondary hypertension causes.
Conditions like renal disease, obstructive sleep apnea, thyroid disorders, and alcohol-induced hypertension require specific management strategies to control blood pressure.
3. Assess caffeine consumption.
High caffeine intake can stimulate sympathetic nervous system activity, increasing blood pressure. Evaluate daily caffeine intake.
4. Review medication list.
Many medications and supplements can elevate blood pressure. Examples include excessive aspirin use, NSAIDs, antidepressants, decongestants, and oral contraceptives. Herbal remedies may also interact with antihypertensive drugs.
Nursing Interventions:
1. Minimize modifiable risks.
Educate patients about substances like cocaine, synthetic cannabinoids, smoking, and excessive alcohol, which increase cardiovascular risk and hypertension.
2. Emphasize treatment adherence.
Educate on the importance of consistently taking prescribed blood pressure medications. Uncontrolled hypertension is a primary trigger for hypertensive crises (BP ≥ 180/120 mmHg).
3. Encourage reporting of all medications and remedies.
Advise patients to maintain an updated medication list, including over-the-counter drugs and herbal remedies, and share it at all appointments to facilitate medication reconciliation and identify potential interactions.
4. Promote blood pressure logging.
Home blood pressure readings should be recorded and reviewed regularly (at least every three months) to assess treatment effectiveness.
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 Factors:
- Lack of interest in physical activity
- Physical limitations or health conditions hindering activity
- Insufficient knowledge about the benefits of exercise on blood pressure
As Evidenced By:
- Deconditioned physical appearance
- Overweight/obese or frail body condition
- Activity intolerance
- Resting tachycardia
- Abnormal heart rate or blood pressure response to activity
Expected Outcomes:
- Patient will engage in physical activity within their capabilities at least 3 times weekly.
- 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 decrease in blood pressure after one month of regular exercise.
Nursing Assessments:
1. Establish rapport with the patient.
Discussing exercise can be sensitive. Build a therapeutic relationship to understand and address patient resistance to lifestyle changes.
2. Assess patient history and interests.
Instead of simply advising exercise, understand the patient’s past activity levels and preferences. 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 stop or reduce activity if they experience significant shortness of breath, fatigue, or dizziness.
Nursing Interventions:
1. Provide coaching and goal-setting support.
Tailor exercise recommendations to the patient’s current activity level, strength, age, and health status. Start with achievable goals, gradually increasing intensity.
2. Monitor and track progress.
Encourage patients to log their activities, exercise duration, and improvements in physical responses or weight loss. Monitor blood pressure changes with regular exercise as directed by their provider.
3. Refer to relevant programs and specialists.
Patients needing supervised exercise may benefit from physical therapy or cardiac rehabilitation programs. Local gyms or community programs can also offer support and affordable classes.
4. Educate on exercise benefits.
Highlight the positive impacts of exercise on cardiovascular health, muscle strength, coordination, and mood. Frame exercise benefits in a way that resonates with the patient’s personal goals and values.
