401210: Conceptual Map and Mrs. Brown Case of Systolic Heart Failure

2.4 Assessment Details
2.4.1 Concept Map and Guided Question Response

Word Count

There is a word limit of 1,500 words. Use your computer to total the number of words used in your assignment. However, do not include the reference list at the end of your assignment in the word count. In-text citations will be included in the additional 10% word count. If you exceed the word limit by more than 10% the marker will stop marking at 1650 words.

Aim of assessment
The purpose of this assessment is to enable students to:

1. Explain in a visual format (concept map) the causes, pathogenesis, clinical manifestations, diagnostic proce- dures, management, course, prognosis, and prevention of systolic heart failure (Learning outcomes 1 and 5).
2. Explain the underlying pathophysiology of the clinical manifestations of an acute exacerbation of chronic systolic heart failure (Learning outcomes 1 and 5).
3. Discuss nursing strategies and evidence-based rationales to manage a patient with an acute exacerbation of chronic systolic heart failure - acute pulmonary oedema (Learning outcomes 2, 4 and 5).
4. Describe the nursing role and responsibilities in the use of pharmacological interventions related to an acute exacerbation of chronic systolic heart failure (Learning outcomes 3 and 5).

Details
You are to develop a concept map for the topic systolic heart failure and answer three questions related to an acute exacerbation systolic heart failure. References are to include six (6) recent, relevant references including journal articles, textbook material and evidence-based resources.

Concept Map (250 words)

• –  The concept map must be computer generated. A template will be provided on VUWS under the assessments tab.
• –  Concept boxes should have titles with relevant content summarised within the box.
• –  The summarised content may be in point format and size 10 font (Arial or Times New Roman) may be used
  on the concept map.
• –  Concept boxes must be linked using lines and linking words/phrases to demonstrate logical relationships between
  concepts.
• –  Most of the information for your concept map will be drawn from the answers to your guided questions.
• –  Referencing of your concept map is not required.
• Guided Questions (1250 words) Case study
• Mrs Brown, a 78 year-old female, was admitted to the Emergency Department at 6am after waking up with severe breathlessness. Her family informed you that the patient has a history of heart failure that had been diagnosed two years ago. On admission to the Emergency Department the signs & symptoms were:

– Severe dyspnoea
– Respiratory rate of 24 breaths/minute
– SpO2 85%, on room air
– BP 170/95mmHg
– Pulse rate of 120 beats/minute
– Auscultation of lungs identifies bilateral basal crackles

Mrs Brown was connected to an ECG monitor that showed atrial fibrillation. A diagnosis of acute exacerbation of chronic systolic heart failure was made.

Question 1. (650 words) (Learning outcome 1 and 5)

Explain the pathogenesis causing the clinical manifestations with which Mrs Brown presented.

Question 2. (400words) (Learning outcomes 2, 4 and 5)

Discuss two high priority nursing strategies to manage Mrs Brown and provide evidence-based rationales for these strategies.

Question 3. (200 words) (Learning outcome 3 and 5)

Two of the drugs that were given to Mrs Brown were IV Furosemide (Lasix) and sublingual Glyceryl Trinitrate (GTN). a. Discuss the mechanism of action of these two drugs, and relate to the underlying pathogenesis of an acute exacerbation of chronic systolic heart failure.
