Hypertension is high blood pressure. The guidelines were updated by the American College of Cardiology in 2017, and a blood pressure (BP) of less than 120/80 mmHg is now considered normal. Anything above this is considered elevated, and stage 1 hypertension is diagnosed at 130/80 mmHg. BP of less than 90/60 mmHg is considered hypotensive.
Hypertension is the most common preventable risk factor for cardiovascular disease and places unnecessary stress on the arteries increasing the risk for stroke, heart attack, and atherosclerosis.

Almost 50% of adults in the United States have hypertension. As a nurse, it is one of the most common comorbidities that require management and treatment.
Patients cannot change risk factors such as family history or ethnicity, but can change lifestyle behaviors. Nurses can assist patients in recognizing risk factors such as smoking, poor diet choices, and stress and educating on ways to reduce their risks. Controlling blood pressure prevents complications and poor health outcomes.
Once the nurse identifies nursing diagnoses for hypertension, nursing care plans help prioritize assessments and interventions for both short and long-term goals of care. In the following section you will find nursing care plan examples for hypertension.
Vasoconstriction from chronic hypertension and vessel resistance can result in decreased cardiac output.
1. Auscultate the heart sounds.
The existence of an S4 heart sound indicates a rigid left ventricle, causing left ventricular hypertrophy and diastolic dysfunction. Both S3 and S4 sounds indicate heart failure.
2. Obtain ECG.
Patients with hypertension are given an electrocardiogram to check for silent myocardial infarction or left ventricular hypertrophy. ECG is useful for assessing heart attacks and thickening/enlargement (hypertrophy) of the heart wall or muscle, which are effects of high blood pressure.
3. Determine the patient’s risk factors for hypertension.
The following tests check for possible causes of hypertension:
4. Assess for signs and symptoms.
Hypertension may be asymptomatic, and the diagnosis is discovered by chance during the recording or measurement of blood pressure. Chronic hypertension results in organ damage such as:
1. Assist the patient in lifelong change.
Since hypertension is a chronic disorder, it requires constant monitoring and management. Exercise, weight management, and limiting alcohol and smoking are crucial to minimizing cardiovascular risk.
2. Administer beta-blockers or calcium-channel blockers as prescribed.
Beta-blockers and calcium channel blockers offer quick heart rate control at rest and during activity. They can be administered intravenously (IV) or orally.
3. Use CPAP or supplemental oxygen at night.
Obstructive sleep apnea requires treatment to reduce sympathetic nervous system stimulation to reduce cardiac workload and blood pressure.
4. Monitor and increase activity as tolerated.
Exercise is a necessity to strengthen the heart and lower blood pressure. Closely monitor the patient’s response to activity through their HR and BP.
5. Limit salt intake.
Consuming excess salt raises the incidence of cardiovascular disease and hypertension. Hypertension results from increased salt absorption leading to increased volume, reduced renin-angiotensin-aldosterone system (RAAS) response, and increased sympathetic nervous system activity.
A lack of understanding of hypertension prevents the patient from making appropriate lifestyle choices and places them at risk for worsening health conditions.
1. Assess the patient’s understanding of hypertension.
Many patients do not understand the role high blood pressure plays in contributing to other conditions and placing them at risk for stroke or heart disease. Assess the patient’s knowledge deficit to fill in the gaps.
2. Assess barriers to learning.
Assess for cognitive, cultural, or language barriers. Perception of the problem and motivation for change is also important. If the patient is not yet ready to learn or does not perceive a reason to, learning will not take place.
3. Assess support systems.
Patients who have difficulty remembering to take medications, monitor their BP, limit salt intake, or follow-up with appointments may need support from family members or friends in order to manage their condition.
1. Help the patient identify their personal risk factors.
Educate between modifiable (stress, diet, weight, tobacco use) vs. non-modifiable risk factors (age, family history, ethnicity). From there, patients can identify areas of improvement.
2. Teach the patient how to monitor blood pressure.
Educate the patient on what their blood pressure number should be, and what is considered high or low. Have the patient bring in their own BP monitor to calibrate it and observe them using it to ensure accuracy of readings.
3. Provide positive reinforcement.
Do not criticize a patient for mistakes or difficulty in implementing their treatment plan. Reinforce any attempt to learn more or even a slight improvement.
4. Review medications thoroughly.
Patients may not understand the purpose of their medications and may skip or miss doses. Review the action, side effects, and rationale of each blood pressure medication as well as the frequency and interactions with other drugs.
An increase in the circulating blood volume will cause the heart to pump harder, increasing blood pressure.
1. Assess for peripheral edema and weight gain.
Excess fluid causes swelling to the extremities, usually the lower legs and feet/ankles. The patient may also notice a sudden weight gain.
2. Assess lab values.
Monitor electrolyte imbalances that are caused by fluid overload such as increased sodium levels or decreased potassium. Monitor renal values that show evidence of fluid retention: BUN, creatinine, urine specific gravity.
3. Assess diet and fluid intake.
An unbalanced diet with either a large amount of sodium or water intake can contribute to fluid overload and increase blood pressure.
1. Educate on fluid and/or sodium restrictions.
Patients with hypertension must be aware of their sodium and fluid intake. This is even more important when coupled with kidney disease or heart failure as this complicates the ability to regulate this balance.
2. Administer diuretics.
Diuretics may be required to rid the body of extra fluid if the patient is displaying symptoms such as shortness of breath or extremely elevated blood pressure.
3. Elevate extremities.
Edematous extremities should be elevated above the level of the heart in order to aid in circulation. Frequent positioning and use of pillows will also prevent skin breakdown.
4. Instruct on low-sodium options.
Patients are often unaware of the amount of sodium in foods. Frozen dinners, canned food, and most restaurant entrees are overloaded with sodium. Educate patients on their daily recommended sodium intake and to limit processed foods and opt for low-sodium options.
Hypertension correlates with the risk for unstable blood pressure (BP) as medical or pharmacologic causes result in elevations in blood pressure.
Nursing Diagnosis: Risk for Unstable Blood Pressure
A risk diagnosis is not evidenced by signs and symptoms as the problem has not yet occurred. Nursing interventions are aimed at prevention.
1. Regularly measure the patient’s blood pressure.
High blood pressure often has no symptoms or warning indications. Many patients are unaware they have it. Regular monitoring is necessary to prevent or detect hypertension.
2. Screen for secondary causes of hypertension.
Renal disease, obstructive sleep apnea, thyroid disorders, and alcohol-induced hypertension require their own management to control blood pressure.
3. Assess caffeine consumption.
High caffeine intake stimulates sympathetic activity, which increases blood pressure. Assess how much caffeine the patient consumes each day.
4. Review the patient’s treatment list.
Numerous drugs and nutritional supplements increase blood pressure. Aspirin used in excessive quantities, NSAIDs, antidepressants, decongestants, and birth control pills are a few examples. Some herbal remedies may interact with antihypertensive medications.
1. Decrease the risk.
Ensure the patient understands that substances such as cocaine, synthetic cannabinoids, cigarette smoking, and excessive alcohol increase the risk of cardiovascular effects and hypertension.
2. Teach the importance of treatment adherence.
Educate on the importance of adhering to blood pressure medication regimens. Uncontrolled blood pressure is the most common cause of a hypertensive crisis: a BP of 180/120 mmHg or higher.
3. Remind the patient to report all medications and remedies.
It is best if the patient keeps an updated list and has this available at all appointments. The nurse can reconcile medications, over-the-counter drugs, and herbal remedies for interactions that may cause unstable blood pressure.
4. Remind the patient to keep BP logs.
Home BP readings should be kept and evaluated at least every three months to monitor the effectiveness of treatment.
A sedentary lifestyle is a risk factor for developing hypertension. Inactivity naturally contributes to a higher heart rate causing the heart to work harder. Those who exercise regularly normally have a lower heart rate, decreasing stress on the heart and arteries.
Nursing Diagnosis: Sedentary Lifestyle
1. Build a rapport.
Exercise can be a difficult subject to broach with patients. Those with a sedentary lifestyle may balk at changing their behavior. It’s important for the nurse to first form a therapeutic relationship with the patient in order to understand and overcome resistance.
2. Assess their history and interests.
Instead of simply telling the patient to move more, get to know what types of exercise or activities they’ve done in the past. Patients are more likely to create a habit when they enjoy what they’re doing.
3. Ensure the patient is safe for activity.
The provider will advise if exercise is unsafe for the patient, but most patients will benefit from some kind of movement. If the patient becomes very short of breath, fatigued, or dizzy from a certain exercise, it should be avoided or decreased.
1. Help with coaching and goal setting.
Depending on the patient’s activity level, strength, age, and health status, meet them where they are in their journey. Walking to the mailbox daily may be a great goal for some, while others may be able to handle more strenuous activity. Start slow and create attainable goals the patient will be excited to reach.
2. Keep track of progress.
Instruct the patient to keep a log of activity completed, time spent exercising, and improvement in physiological responses or weight loss. Along with this, the patient should be monitoring their BP as directed by their provider, and they may notice a decrease in their blood pressure along with regular exercise.
3. Refer to PT, cardiac rehab, or local programs.
Patients who require a more supervised approach may need PT evaluation for safety modifications. Cardiac rehab teaches exercise training specific to heart health. Patients may also find support from their local gym or programs that offer free or low-cost classes.
4. Educate on the benefits and necessity of exercise.
Exercise not only benefits the heart and circulation, but it also improves muscle strength, coordination and boosts mood. Patients should not be scared into exercising for fear of illness, but providing the positive aspects that are relevant to them (more time with grandkids, for example) will help them see the benefits.
