hypertension - Nursing Case Study

Pathophysiology

• Primary mechanism: Increased Blood Volume - The kidneys control blood volume by managing fluid and sodium levels. When sodium levels increase, the body retains more water, raising blood volume and pressure against vessel walls, causing hypertension.

• Secondary mechanism: Narrowed Blood Vessels - The arteries can narrow due to stress, genetics, or unhealthy lifestyle choices. This narrowing increases resistance to blood flow, forcing the heart to pump harder, which elevates blood pressure.

• Key complication: Organ Damage - Consistently high blood pressure can damage vital organs like the heart, kidneys, and brain, leading to conditions such as heart disease, kidney failure, or stroke.

Section 1

During his routine follow-up visit, the patient undergoes a comprehensive initial assessment to evaluate his current health status and the effectiveness of his hypertension management plan. The nurse notes that the patient's blood pressure reading of 135/85 mmHg is slightly elevated, but it is within an acceptable range for someone on antihypertensive medication. Upon further examination, the patient reports experiencing mild headaches occasionally, which he attributes to work-related stress. His heart rate remains steady at 72 bpm, with a normal respiratory rate of 16 breaths per minute and a temperature of 98.6°F. The nurse conducts a physical examination and finds no signs of jugular venous distension, edema, or abnormal heart sounds, indicating stable cardiovascular function at this stage.

Laboratory tests are ordered to monitor the patient's renal function and electrolyte balance, as these are crucial in managing hypertension. The results reveal a serum sodium level of 142 mmol/L, which is within the normal range, and a serum creatinine level of 1.0 mg/dL, indicating adequate kidney function. The patient's lipid profile shows a total cholesterol of 190 mg/dL, HDL of 50 mg/dL, LDL of 120 mg/dL, and triglycerides at 150 mg/dL. These values suggest that while his lipid levels are not critically high, lifestyle modifications could help improve his cardiovascular health further.

Based on the assessment findings and laboratory results, the healthcare team reinforces the importance of adhering to a low-sodium diet, regular physical activity, and stress management techniques to maintain optimal blood pressure control and prevent organ damage. The patient is encouraged to monitor his blood pressure at home and report any significant changes or symptoms. The follow-up plan includes a re-evaluation in three months to assess the effectiveness of his current treatment regimen and make any necessary adjustments.

Three months later, the patient returns for his follow-up appointment as planned. During the initial assessment, the nurse notes that his blood pressure has improved slightly to 132/82 mmHg, suggesting a positive response to the current treatment regimen. The patient reports that he has been diligent in following the recommended lifestyle modifications, including maintaining a low-sodium diet, engaging in regular physical activity, and practicing stress management techniques such as yoga and deep breathing exercises. He also mentions that his occasional headaches have decreased in frequency and intensity, attributing this improvement to better stress management at work.

The nurse conducts a thorough physical examination and finds that the patient's heart rate is now at 70 bpm, with a respiratory rate of 15 breaths per minute and a temperature of 98.4°F. These stable vital signs, combined with the absence of any new symptoms or physical concerns such as edema or abnormal heart sounds, indicate that the patient's cardiovascular function remains stable. The patient is also consistent in monitoring his blood pressure at home, reporting no significant fluctuations or alarming changes.

Laboratory results are reviewed, showing a slight improvement in the patient's lipid profile: total cholesterol at 185 mg/dL, HDL at 52 mg/dL, LDL at 115 mg/dL, and triglycerides at 145 mg/dL. These results reflect a modest yet encouraging trend towards better cardiovascular health. Given the patient's positive response to the current interventions, the healthcare team decides to continue with the existing management plan, emphasizing the importance of ongoing lifestyle modifications. A follow-up appointment is scheduled in another three months to ensure the patient's condition remains under control and to make any necessary adjustments based on future assessments.

Section 3

Three months later, the patient returns for his scheduled follow-up appointment. During the initial assessment, the nurse notes a further improvement in his blood pressure, now reading 128/80 mmHg, indicating continued success with the treatment plan. The patient expresses satisfaction with his progress and shares that he has incorporated additional lifestyle changes, such as joining a community walking group, which has increased his physical activity levels to 45 minutes of brisk walking five times a week. He also reports feeling more energetic and experiencing fewer episodes of fatigue.

The nurse conducts a comprehensive physical examination and observes that the patient's vital signs remain stable, with a heart rate of 68 bpm, respiratory rate of 14 breaths per minute, and a temperature of 98.6°F. There are no signs of edema or abnormal heart sounds, and the patient's skin appears well-hydrated. These findings suggest that the patient's cardiovascular health is not only stable but potentially improving. The patient mentions that he continues to practice stress management techniques, and he attributes his improved mood and energy levels to these practices.

Laboratory results show further positive changes, with the patient's total cholesterol now at 178 mg/dL, HDL increased to 55 mg/dL, LDL reduced to 110 mg/dL, and triglycerides decreased to 140 mg/dL. These results are encouraging and demonstrate the effectiveness of the patient's adherence to his lifestyle modifications. The healthcare team decides to maintain the current management plan, praising the patient for his commitment and encouraging him to sustain these healthy habits. Another follow-up is scheduled in three months to monitor ongoing improvements and ensure the patient's condition remains well-managed.

Section 4

Three months later, the patient returns for his next follow-up appointment. During the initial assessment, the nurse observes that the patient's blood pressure remains stable at 126/78 mmHg. The patient continues to report satisfaction with his progress and mentions that he has maintained his physical activity regimen, now including light strength training twice a week. He reports feeling even more energetic and states that his episodes of fatigue have nearly disappeared. The nurse notes that the patient’s heart rate is 70 bpm, respiratory rate is 15 breaths per minute, and temperature is 98.7°F, all within normal ranges. Additionally, the patient’s skin remains well-hydrated, with no signs of edema, and heart sounds are normal upon auscultation.

The patient expresses a new concern regarding occasional dizziness when standing up quickly.
