Hypertension - Nursing Case Study

Pathophysiology

• Primary mechanism: Increased Peripheral Resistance - The blood vessels, especially small arteries, become narrower (vasoconstriction), making it harder for blood to flow through, which raises blood pressure. This can occur due to factors like high sodium intake or stress, leading to prolonged vessel constriction.

• Secondary mechanism: Increased Blood Volume - Excessive sodium in the body can cause the body to retain more water, increasing blood volume. More blood volume means more pressure on the vessel walls, contributing to higher blood pressure.

• Key complication: Organ Damage - Over time, high blood pressure can damage vital organs like the heart, kidneys, and eyes, leading to complications such as heart disease, kidney failure, or vision problems.

Section 1

Initial Assessment Findings:

During the routine follow-up appointment, the nursing assessment focused on evaluating the patient's adherence to her medication regimen and lifestyle modifications recommended for managing stage 1 hypertension. The patient reports taking Lisinopril consistently but admits to occasional lapses in adhering to a low-sodium diet, particularly during periods of increased work-related stress. Despite these lapses, she has been engaging in regular physical activity, including walking for 30 minutes at least five times a week.

The physical examination reveals that the patient's blood pressure remains slightly elevated at 135/85 mmHg, indicating the need for continued monitoring and possible adjustment in management strategies. Her heart rate is stable at 78 bpm, with no irregularities detected during auscultation. The patient reports occasional mild headaches, which she attributes to work stress and manages with over-the-counter analgesics. The nursing assessment identifies the need for reinforced patient education on dietary modifications to reduce sodium intake and stress management techniques to help mitigate the potential impact on her blood pressure.

These findings suggest the importance of addressing lifestyle factors as part of the comprehensive management of hypertension. The nurse plans to collaborate with the patient to set realistic goals for sodium reduction, incorporate stress-reducing activities such as mindfulness or yoga, and schedule a follow-up appointment in three months to reassess her blood pressure and evaluate the effectiveness of the current management plan. This approach aims to prevent progression to more severe stages of hypertension and minimize the risk of long-term organ damage.

During the next follow-up appointment, three months later, the patient presents with new diagnostic results that provide further insight into her hypertension management. Her blood pressure has decreased slightly to 132/82 mmHg, a positive indication of her improved adherence to lifestyle modifications. The patient has diligently reduced her sodium intake by preparing meals at home using fresh ingredients and choosing low-sodium options when dining out. She also reports practicing mindfulness exercises daily, which she finds beneficial in managing work-related stress.

Recent laboratory tests reveal normal renal function with a serum creatinine level of 0.9 mg/dL and an estimated glomerular filtration rate (eGFR) of 90 mL/min/1.73m², suggesting that there has been no significant impact on kidney function. Her lipid profile shows a total cholesterol level of 190 mg/dL and LDL cholesterol level of 110 mg/dL, both within acceptable ranges, although the nurse emphasizes the importance of maintaining these levels through continued dietary vigilance and physical activity.

The patient's occasional mild headaches have decreased in frequency, which she attributes to the incorporation of stress management techniques. The nurse praises the patient's efforts and encourages her to continue these practices while also suggesting the addition of yoga classes to further support her stress reduction goals. The nurse plans to maintain the current medication regimen, emphasizing the importance of consistent adherence to Lisinopril, and schedules the next follow-up appointment in another three months to monitor for any further improvements or necessary adjustments. This continued collaborative approach aims to solidify the patient's progress and prevent any escalation of her hypertension.

Three months later, the patient returns for her scheduled follow-up appointment, presenting with a blood pressure reading of 130/80 mmHg, indicating further improvement in her hypertension management. During the initial assessment, the nurse notes that the patient appears more energetic and reports feeling less fatigued throughout the day. The patient explains that she has incorporated light jogging into her routine, which has contributed to her overall sense of well-being. Vital signs are stable, and her heart rate is 72 beats per minute with regular rhythm. The patient’s BMI has decreased slightly to 26 kg/m², reflecting her commitment to lifestyle changes.

The nurse conducts a thorough review of systems and discovers that the patient has been experiencing occasional dizziness, particularly when standing up quickly. This prompts the nurse to consider the possibility of orthostatic hypotension, a common side effect of antihypertensive medication like Lisinopril. The nurse decides to perform orthostatic blood pressure measurements, noting a drop in systolic pressure of 15 mmHg upon standing. This finding leads to a discussion about the importance of changing positions slowly and staying hydrated to alleviate symptoms.

To address this minor complication, the nurse collaborates with the primary care provider to adjust the patient’s Lisinopril dosage slightly, aiming to maintain optimal blood pressure control while minimizing adverse effects. The nurse educates the patient about recognizing symptoms of orthostatic hypotension and provides strategies to manage them effectively. The patient is encouraged to continue her lifestyle modifications and stress management practices while monitoring her symptoms closely. The nurse schedules a follow-up phone call in two weeks to reassess the patient’s response to the adjusted medication regimen and ensure continued progress in her hypertension management journey.

Two weeks later, during the scheduled follow-up phone call, the nurse checks in with the patient to assess her response to the adjusted Lisinopril dosage. The patient reports that she has experienced a significant reduction in episodes of dizziness, especially when transitioning from sitting to standing. She expresses relief and satisfaction with the adjustment, noting that her day-to-day activities have become more manageable. The nurse documents the patient's blood pressure readings taken at home, which consistently hover around 128/78 mmHg, indicating that her blood pressure remains well-controlled.

In addition to monitoring blood pressure, the nurse inquires about any new symptoms or concerns. The patient mentions mild swelling in her ankles by the end of the day, which is a new development since the last visit. Upon further discussion, the nurse learns that the patient’s daily water intake has increased as part of her efforts to stay hydrated, possibly contributing to the fluid retention. The nurse advises the patient to elevate her legs when resting and to continue monitoring the swelling.

To ensure comprehensive care, the nurse arranges for a follow-up appointment at the clinic to evaluate the edema more thoroughly. During this visit, the nurse plans to review potential lifestyle or dietary adjustments that may help alleviate the swelling, such as reducing sodium intake or modifying fluid consumption. The nurse also considers the possibility of further medication adjustment if the swelling persists, collaborating with the healthcare team to maintain an optimal balance in the patient's hypertension management plan.

Section 5

Two weeks after the follow-up phone call, the patient arrives at the clinic for her scheduled appointment. During the initial assessment, the nurse observes that the patient appears well-groomed and in good spirits. The patient's vital signs are stable, with a blood pressure reading of 126/76 mmHg, a heart rate of 72 beats per minute, and a respiratory rate of 18 breaths per minute. The nurse notes mild pitting edema in the patient's ankles, which is slightly more pronounced than previously reported. This finding indicates mild fluid retention, but otherwise, the patient does not exhibit any signs of distress or discomfort.

As part of the comprehensive assessment, the nurse discusses the patient's dietary habits and fluid intake. The patient reveals that she has been enjoying more soups and pre-packaged meals recently, which may inadvertently have increased her sodium intake. Additionally, the patient admits to being less active due to a recent busy schedule, which could contribute to her fluid retention. The nurse educates the patient on the importance of maintaining a low-sodium diet and suggests incorporating more fresh fruits and vegetables to help manage her symptoms. The nurse also emphasizes the importance of regular physical activity to promote circulation and reduce swelling.

With these findings, the nurse collaborates with the healthcare team to decide on the next steps. The team opts to monitor the patient's condition closely while implementing these lifestyle changes. They schedule another follow-up visit in four weeks to reassess the edema and overall management of her hypertension. The nurse reassures the patient that with consistent lifestyle modifications and ongoing monitoring, her symptoms can be effectively managed, ensuring her blood pressure remains well-controlled and her quality of life is maintained.
