Microorganisms, Pathogens, and Pharmacological Interventions - A Case Study of Influenza - Medical Science Assignment Help

Assignment Task

Aim of assessment
The aim of this assessment is to increase students` understanding of how microorganisms can cause health breakdown, and the role of relevant pharmacological interventions in the recovery processes. Students will explore various modes of transmission, relevant characteristics of pathogens and the importance of breaking the chain of infection.

Assessment details:

A minimum of five of the eight references provided as resources must be used and cited in this case study.
You must use the supplied template, which must be accessed from the Assessment 2 tab in the subject`s vUWS site, to answer the questions that follow the case study below.

Case Study:

Peter Smith, a 19-year-old man, was suffering from influenza and visited his local GP. He said he began to feel unwell two days earlier and his condition had worsened since, with an acute onset of a sore throat (pharyngitis)

On examination the following observations were made:

• Fever of 38.9 degrees C
• Runny nose
• Sneezing
• Enlarged anterior cervical lymph nodes (lymphadenopathy)
  

Peter`s throat was observed to have the following signs:

• Redness
• Swelling
• Having a patchy covering of yellow-white exudate over his tonsils

The doctor prescribed phenoxymethylpenicillin 500 mg twice per day for ten days.

Answer the following questions:
Q1. Explain what fever is and the pathophysiology of how Peter`s fever developed. State, with explanation, two benefits of fever.

Q2. Given that influenza is caused by a virus, why was Peter prescribed an antibiotic? The doctor prescribed phenoxymethylpenicillin. Discuss the mode of action of phenoxymethylpenicillin. Explain why antibiotics are not effective against viruses. 

Q3. Name and describe three (3) possible ways that Peter could have contracted the influenza virus (starting from the source followed by modes of transmission). Identify and explain two (2) ways by which these three modes of transmission could be broken. 

Q4. Compare and contrast the processes by which viruses and bacteria replicate.
