Cost Analysis:

The cost of atenolol can vary depending on the pharmacy and dosage. However, it is generally considered an affordable medication.

Patient Case Study

Patient: A 65-year-old male with a history of hypertension and type 2 diabetes mellitus.

Presentation: The patient presents with complaints of chest pain, shortness of breath, and fatigue. Physical examination reveals a blood pressure of 160/90 mmHg.

Diagnosis: Stable angina pectoris

Treatment: Atenolol 25 mg once daily is prescribed.

Peer-Reviewed Evidence-Based Studies:

1. The Cardiac Outcomes and Mortality in Patients with Chronic Heart Failure in the Elderly (COME-CHF) Trial: This study demonstrated the effectiveness of atenolol in reducing mortality and improving symptoms in patients with chronic heart failure.
2. The Randomized Intervention for Cardiovascular Events in Women (RIWEN) Study: This study found that atenolol was effective in reducing cardiovascular events in women with hypertension.

Patient Education:

• Medication Adherence: Emphasize the importance of taking atenolol as prescribed, even if symptoms improve.
• Side Effects: Inform the patient about common side effects and advise them to report any significant adverse reactions.
• Blood Pressure Monitoring: Instruct the patient to monitor their blood pressure regularly and report any significant changes.
• Lifestyle Modifications: Advise the patient to make lifestyle modifications, such as quitting smoking, reducing alcohol consumption, and maintaining a healthy diet and exercise regimen.

Role of the Nurse Practitioner:

As a nurse practitioner, I would:

• Diagnose the patient's condition based on their symptoms, medical history, and physical examination.
• Prescribe the appropriate dose of atenolol based on the patient's individual needs and risk factors.
• Monitor the patient's response to treatment and adjust the dosage as needed.
• Educate the patient about the medication, its side effects, and the importance of adherence.
• Refer the patient to a cardiologist for further evaluation if necessary.

Monitoring and Follow-Up:

• Blood Pressure: Monitor the patient's blood pressure regularly to assess the effectiveness of the medication.
• Heart Rate: Monitor the patient's heart rate for signs of bradycardia.
• Side Effects: Assess for any adverse effects and adjust the dosage or consider alternative medications if necessary.
• Follow-Up Visits: Schedule regular follow-up visits to evaluate the patient's response to treatment and make any necessary adjustments.

By providing comprehensive care and education, nurse practitioners can play a vital role in managing patients with hypertension, angina, and heart failure.
