Left Sided Heart Failure Concept Map
Information 1 – Getting started.
Your first assessment is generating a concept map for left heart failure and answering three questions related to a case study about a patient who has an acute exacerbation of heart failure. When preparing your assignment refer to the criteria and standards in the Learning Guide. Left Sided Heart Failure Concept Map
You can begin this assessment now by finding readings about heart failure and summarising the information under the headings of the pathophysiology template. This information can then be used for your concept map.
Some readings that you may find helpful to start your assignment are:
Craft,J.A., Gordon,C.J., Huether,S.E., McCance, K.L., Brashers, V.L. & Rote,N.E.
(2015). Understanding pathophysiology – ANZ adaptation (2nd ed.).
Chatswood, NSW: Elsevier Australia. Chapter 23.
Aitken, L., Marshall,A. & Chaboyer, W. (2015). ACCCN’s critical care nursing
(3rd ed.). Chatswood, NSW: Elsevier Australia. Chapter 10.
Wagner, K.D. (2014). High acuity nursing (6th ed.). Upper Saddler River, New
Jersey: Pearson. Chapter13.
(These books are available online from the Western Sydney University library).
This is just to begin. You will then find more readings to add to your information.
Remember that the information in your concept map and answers to the questions must correlate with the references that you cite so keep an accurate record when preparing your assignment. The marker of your assessment will check your citations. Left Sided Heart Failure Concept Map
An example of a pathophysiology template for a left-sided ischaemic stroke and a concept map using this information has been attached to start you thinking about how you will approach your assignment. The concept map has been generated using Word. However, if you wish, you may prefer to use a concept map template that you may find on the web.

· Reperfusion Thrombolytic (tPA )
Nursing acute phase
· Frequent evaluation of neurological status and vital signs
· Oxygen saturations – administer oxygen if required
· Screen for swallowing – manage hydration and nutrition
· Manage activities of daily living
· Address appropriate communication strategies
· Prevent complications
· Passive and active movement
· Encourage activities provided by physiotherapists, speech and occupational therapists e.g. mobility, speech, ADL
· Neuroprotection – e.g, aspirin
Course of disease
With reperfusion – blood restored to area, many symptoms gradually resolve
Without treatment – ischaemia extends to penumbra –symptoms worsen. Recovery may continue 6 months to a year but left with disability. Requires rehabilitation to optimise function 8
· Mood disturbances
· Dysarthria and aphasia
