Survey Note: Comprehensive Analysis of Pharmacotherapy Case Studies for Cardiovascular Disorders

This section provides a detailed examination of the suggested pharmacotherapy case study assignments, designed to align with the provided example and cater to nursing education needs. Each case study is crafted to facilitate academic writing and analysis, focusing on factors influencing pharmacokinetic and pharmacodynamic processes. The analysis includes patient profiles, medical histories, and potential areas for student exploration, ensuring a robust learning experience.

Background and Methodology

The development of these case studies draws from existing literature and clinical examples, such as those found in Case Studies: Cardiovascular Health and Clinical case studies in heart failure management, to ensure realism and educational value. Each case is structured to include comprehensive patient data, mirroring the provided example’s format, which includes past medical history (PMH), medications, allergies, social history, vitals, labs, and physical examination (PE). The focus is on cardiovascular disorders, with each case highlighting a different factor—genetics, gender, ethnicity, age, or behavior—for students to analyze in their 2- to 3-page papers.

The process involved reviewing case studies from credible sources to ensure alignment with current pharmacotherapy practices. The cases are designed to allow students to select one factor (genetics, gender, ethnicity, age, or behavior) and reflect on its influence on drug therapy, as per the assignment instructions.

Detailed Case Study Descriptions

Below is a table summarizing the five case studies, followed by in-depth descriptions:

Case Study 1: Heart Failure

• Patient Profile: Mr. JW, a 75-year-old male, presents with shortness of breath and fatigue, diagnosed with heart failure with reduced ejection fraction (HFrEF, EF 30%), hypertension, type 2 diabetes, and chronic kidney disease stage 3.
• Medical Details: Retired engineer, lives with wife, former smoker (quit 10 years ago), occasional alcohol use. Vitals include BP 130/80 mmHg, HR 70 bpm, weight 85 kg, height 170 cm. Labs show Na 138, K+ 4.5, glucose 120, SCr 1.5, eGFR 45, HbA1c 7.0%, BNP 500. PE shows S3 gallop, bibasilar crackles, 1+ edema.
