Hypertension in acute setting - Nursing Case Study
Pathophysiology
• Primary mechanism: Increased resistance in blood vessels causes the heart to pump harder, elevating blood pressure. This can occur due to stress, pain, or fluid overload, leading to acute hypertension.
• Secondary mechanism: Activation of the sympathetic nervous system releases hormones like adrenaline, which further constricts blood vessels and increases heart rate, contributing to higher blood pressure.
• Key complication: Acute hypertension can lead to minor complications like headaches or blurred vision due to increased pressure on small blood vessels in the brain and eyes.

Section 1
Initial Assessment Findings:
Upon further examination, the nurse conducts a thorough assessment to gather more data about the patient's current condition. The patient reports that her headaches have been occurring more frequently over the past week, typically in the late afternoon, but they resolve with rest and hydration. She denies any visual disturbances or other neurological symptoms. Physical examination reveals no focal neurological deficits, and the patient's pupils are equal, round, and reactive to light. Her skin is warm and dry, and there are no signs of edema.
The nurse checks the patient's blood pressure again, noting a slight increase to 142/92 mmHg. A review of her medication regimen confirms that she has been compliant with her daily dose of Lisinopril. However, she admits that her workload has been particularly stressful recently, which could be contributing to her elevated blood pressure. The nurse also notes that the patient has not been monitoring her blood pressure at home, which may provide valuable information about daily fluctuations.
Based on these findings, the nurse determines that the patient's symptoms are likely related to her mild hypertension and recent increase in stress levels. The nurse reinforces the importance of lifestyle modifications, such as stress management techniques and regular physical activity, to help control her blood pressure. The patient is encouraged to maintain a blood pressure log at home and schedule a follow-up appointment with her primary care provider to evaluate the need for any adjustments in her treatment plan. This assessment leads to the next steps in managing her condition, focusing on non-pharmacological interventions and close monitoring.

In the following days, the patient diligently follows the nurse's advice to log her blood pressure readings at home. She utilizes a home blood pressure monitor and records her measurements twice daily, in the morning and evening, to capture any variations throughout the day. The patient notices a pattern of higher readings in the late afternoon, consistent with the times she experiences headaches. Her blood pressure readings range from 138/88 mmHg in the morning to 145/94 mmHg in the late afternoon. These findings suggest a correlation between her stress levels and her blood pressure fluctuations.
The patient also begins incorporating stress management techniques, such as deep breathing exercises and short walks during her work breaks, which she finds helpful in reducing her overall tension. She reports feeling slightly more relaxed and less overwhelmed by her workload. At the follow-up appointment with her primary care provider, she shares her blood pressure log and describes the lifestyle changes she has implemented. Her provider commends her efforts and emphasizes the importance of continuing these non-pharmacological interventions alongside her medication regimen.
To further support the patient's progress, the primary care provider orders a set of basic laboratory tests, including a complete blood count (CBC), basic metabolic panel (BMP), and lipid profile, to assess any underlying factors that may contribute to her hypertension. These tests reveal slightly elevated cholesterol levels but are otherwise unremarkable. The provider discusses the results with the patient, highlighting the need for dietary modifications to address her cholesterol levels. This discussion leads to a referral to a dietitian for personalized dietary guidance, marking the next step in her hypertension management plan.
Section 3
In the weeks following her visit to the dietitian, the patient diligently incorporates the recommended dietary changes, which include reducing her intake of saturated fats and increasing her consumption of fruits, vegetables, and whole grains. She also continues her stress management techniques and adheres to her medication regimen. During a routine follow-up visit, the nurse conducts an initial assessment, noting that the patient appears more energetic and reports feeling less fatigued. Her blood pressure readings have improved, now averaging 130/85 mmHg in the morning and 135/88 mmHg in the late afternoon.
The nurse also reviews the patient’s recent laboratory results and finds a notable improvement in her lipid profile. Her total cholesterol has decreased to 190 mg/dL from a previous 210 mg/dL, and her LDL cholesterol has dropped from 140 mg/dL to 120 mg/dL. These changes suggest that the dietary modifications and lifestyle interventions are positively impacting her cardiovascular risk factors. The nurse reinforces the importance of maintaining these lifestyle changes and encourages the patient to continue monitoring her blood pressure and adhering to her treatment plan.
Despite these positive developments, the patient mentions experiencing occasional dizziness when standing up quickly. The nurse performs an orthostatic blood pressure assessment, revealing a drop of 15 mmHg systolic when the patient moves from sitting to standing. This finding indicates orthostatic hypotension, likely a side effect of her antihypertensive medication. The nurse advises the patient to rise slowly from sitting or lying positions and discusses these findings with the primary care provider. The provider considers adjusting her medication dosage to alleviate this side effect, ensuring her treatment plan remains effective and tolerable. This adjustment marks the next phase in optimizing her hypertension management while minimizing adverse effects.

Following the adjustment of her antihypertensive medication, the patient returns for another follow-up visit after two weeks. During the initial assessment, the nurse notes that the patient appears well-rested and continues to report improvements in energy levels. The patient states that she has been diligent in following the nurse's advice to rise slowly from sitting or lying positions, and she has experienced a significant reduction in episodes of dizziness. Her blood pressure readings are now more consistent, averaging 128/82 mmHg in the morning and 132/85 mmHg in the late afternoon, indicating that the medication adjustment has been beneficial in stabilizing her blood pressure without causing orthostatic hypotension.
The nurse reviews the patient's recent laboratory results and observes further positive changes. Her total cholesterol has decreased to 185 mg/dL and her LDL cholesterol is now at 115 mg/dL, reflecting ongoing improvements in her lipid profile. The patient's blood glucose level remains stable at 95 mg/dL, and her kidney function tests show normal creatinine and blood urea nitrogen levels, suggesting that her kidneys are functioning well and not adversely affected by her current medication regimen.
These findings indicate that the combination of lifestyle modifications and optimized medication management is effectively controlling her hypertension and improving her overall cardiovascular health. The nurse commends the patient for her commitment and encourages her to maintain these healthy habits. Additionally, the nurse schedules the next follow-up visit to continue monitoring the patient's progress and ensure that any potential complications are addressed promptly. As the patient leaves the clinic, she feels reassured by her progress and motivated to continue her journey toward better health.
Section 5
Two weeks later, the patient returns for her scheduled follow-up visit and the nurse conducts another thorough assessment. The patient continues to report feeling well, but mentions experiencing occasional mild headaches, particularly in the evenings. During the vital signs check, her blood pressure readings are noted to be slightly elevated, averaging 135/88 mmHg in the morning and 138/90 mmHg in the late afternoon. While these readings are still within a manageable range, they indicate a slight upward trend compared to her previous visit. Her heart rate remains steady at 72 beats per minute, and her respiratory rate is normal at 16 breaths per minute. The nurse also observes that the patient's weight has remained stable, and her body mass index (BMI) is within a healthy range, reflecting her continued dedication to lifestyle modifications.
The nurse reviews the patient's most recent laboratory results and finds that her lipid profile remains favorable, with a total cholesterol of 180 mg/dL and an LDL cholesterol level of 110 mg/dL. However, there is a slight increase in her fasting blood glucose level, now at 100 mg/dL, which is still within the normal range but warrants monitoring. Her kidney function tests remain normal, with creatinine and blood urea nitrogen levels consistent with previous results. The nurse discusses these findings with the patient, emphasizing the importance of vigilance in monitoring her blood pressure and blood glucose levels to prevent any potential complications.
The nurse decides to collaborate with the healthcare provider to evaluate whether a minor adjustment to the antihypertensive medication might be beneficial to address the slight increase in blood pressure and occasional headaches. Additionally, the nurse reinforces the importance of maintaining a balanced diet, regular physical activity, and stress management techniques. The patient is encouraged by the overall positive trajectory of her health and agrees to continue her current regimen while staying alert to any changes in her condition. A follow-up appointment is scheduled to reassess her response to any modifications and to ensure her continued progress towards optimal health.
