Referencing Styles : APA Case Study 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. Answer the following questions in relation to the information provided in this case study: 1.a) Define MRSA? (150 WORDS) Methicillin-resistant Staphylococcus aureus (MRSA) is an infection that is caused by a certain type of staph bacteria and is commonly known as a “super bug”. It’s a bacterium that causes infections in different parts of the human body and is very hard to treat because most strains of staphylococcus aureus or staph becomes very resistant to beta-lactam antibiotics. The majority of MRSA infections fall under the category known as CA-MRSA (commonly acquired) or HA-MRSA (hospital or healthcare acquired).MRSA isn’t found in our natural environment, being soil and water, but instead it lives in the nose and on the skin of humans. MRSA is spread when a person comes in contact with an infection person or by being exposed to a MRSA contaminated object or surface in which an infected person has touched (MedicineNet,2015). CA-MRSA will start out as a skin infection, for example sores or boils, but HA-MRSA begins as an infection of the skin, sometimes a surgical wound or even a site where medical devices have been placed, for example catheters or IV lines. Although most MRSA infections aren’t serious, but some can certainly be life threatening (WEBMD n.d.). b) Why is it antibiotic resistant? (150 WORDS) c) Discuss the complications this organism 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 reservoir/ host, portal of entry/exit, transmission and discuss how these occurred in Mr. Jones’ case. (150 WORDS) b) standard/additional precautions (150 WORDS) c) 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)
