Discuss the major complications MRSA may have on wound healing and other body systems.

Discuss the major complications MRSA may have on wound healing and other body systems.

John Jones, age 32, is admitted to your ward  after post-surgical lancing of a cutaneous abscess located on his perineum.  The abscess was caused by MRSA bacteria.  The abscess required excision and drainage to remove pus and debris.

Mr. Jones is under police guard as he has been on remand at the nearby Correctional Centre for the past 2 days awaiting trial related to holding an illegal drug.  Mr. Jones has a history of IV heroin use and homelessness. He states that he last used heroin “about 4 days ago”.  Mr. Jones’s medical history reveals that he has previously been admitted to hospital for depression and a suicide attempt.  His blood tests returned positive for Hepatitis C.  Insulin levels are within the normal range and chest x ray returned clear.  His BMI is 20kg/m2, weight is 65kg and height 180cm.

You read the surgeon’s post-operative instructions:

Wound cavity to be dressed daily with Betadine-soaked gauze packing

Mr. Jones  is visited by the wound management nurse who documented the following in his notes:

Wound to heal by secondary intention

Wound cavity measures 12mm long x 11mm wide and 10mm deep, extending to the subcutaneous tissue layer

Wound bed consists of 100% granulation tissue; is malodorous and is oozing large amounts of haemoserous exudate.

Based on this assessment, the wound management nurse disagreed with the surgeon’s post-operative wound management strategy.

b)  Why is it antibiotic resistant? (150 WORDS)

c) Discuss the major complications MRSA may have on wound healing and other body systems. (150 WORDS) REFERENCE EACH SECTION.


2. What special infection control considerations would you implement for Mr Jones? In your answer include the following –

a) the chain of infection – include each step in the chain eg. reservoir/ host, portal of entry/exit, transmission and show how these occurred in Mr. Jones’ case. (150 WORDS)

b) standard/additional precautions – clearly identify the differences between them (150 WORDS)

c)  infection control education required for Mr. Jones and the police guard.  (150 WORDS)


3. What is a secondary intention wound?  Include in your answer a description of primary and tertiary intention wounds. (150 WORDS)


4. There are three overlapping phases in wound healing known as the inflammatory, proliferative and maturation phases.  Explain each of these physiological processes. (150 WORDS)



5. Wound Bed Preparation uses four principles in the acronym T.I.M.E which provides a systematic approach to the management of wounds.  Discuss what is meant by:

a. Wound bed preparation

b. T.I.M.E – give a definition for each initial (150 WORDS)


6. Why do you think the wound management nurse disagrees with betadine-soaked gauze packing as a dressing choice for Mr Jones’s cavity wound?  Support your answer with evidence-based research. (Check the journal article in “additional resources” on Healing By Secondary Intention as it discusses the correct answer). (150 WORDS)


7. Discuss one (1) contemporary (recent) wound management strategy for any wound patient. Support your answer with evidence-based research. This could be a new dressing, vac systems, maggot or honey therapy or ANY new wound strategy.  Give both the advantages and disadvantages of your chosen therapy. (150 WORDS)



8. What impact will the following issues have on Mr. Jones wound healing?

a) poor nutrition

b) depression

c) homelessness

d) IV drug use

e) hepatitis


Put each of the above issues under a heading and discuss each in detail.  Support each issue with research and a clear rationale (reason) for why it will affect his healing. In this question we are looking for your ability to problem solve and critically think.
