NR507 Advanced Pathophysiology

Week 2 Discussion

Purpose

The purpose of the graded collaborative discussions is to engage faculty and students in an interactive dialogue to assist the student in organizing, integrating, applying, and critically appraising knowledge regarding advanced nursing practice. Scholarly information obtained from credible sources as well as professional communication are required. Application of information to professional experiences promotes the analysis and use of principles, knowledge, and information learned and related to real-life professional situations. Meaningful dialogue among faculty and students fosters the development of a learning community as ideas, perspectives, and knowledge are shared.

Activity Learning Outcomes

Through this discussion, the student will demonstrate the ability to:

Explain the pathophysiology of heart failure by analyzing a patient's symptoms. (CO1)

Differentiate between systolic and diastolic heart failure. (CO1)

Explain the significance of physical exam and diagnostic findings in the diagnosis of heart failure. (CO4)

Requirements:

Read the case study below.

In your initial discussion post, answer the questions related to the case scenario and support your response with at least one evidence-based reference by Wed., 11:59 pm MT.

Respond to at least one peer and all faculty questions directed at you, using appropriate resources, before Sun., 11:59 pm MT.

Case Scenario:

A 72-year-old male presents to the primary care office with shortness of breath, leg swelling, and fatigue. He reports that he stopped engaging in his daily walk with friends three weeks ago because of shortness of breath that became worse with activity. He decided to come to the office today because he is now propping up on at least 3 pillows at night to sleep. He tells the NP that he sometimes sleeps better in his recliner chair. PMH includes hypertension, hyperlipidemia and Type 2 diabetes.

Physical Exam:

BP 106/74 mmHg, Heart rate 110 beats per minute (bpm)

HEENT: Unremarkable

Lungs: Fine inspiratory crackles bilateral bases

Cardiac: S1 and S2 regular, rate and rhythm; presence of 3rd heart sound; jugular venous distention. Bilateral pretibial and ankle 2+pitting edema noted

ECG: Sinus rhythm at 110 bpm

Echocardiogram: decreased wall motion of the anterior wall of the heart and an ejection fraction of 25%

Diagnosis: Heart failure, secondary to silent MI

Discussion Questions:

Differentiate between systolic and diastolic heart failure.

State whether the patient is in systolic or diastolic heart failure.

Explain the pathophysiology associated with each of the following symptoms: dyspnea on exertion, pitting edema, jugular vein distention, and orthopnea.

Explain the significance of the presence of a 3rd heart sound and ejection fraction of 25%.
