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. This assessment facilitates the development of the following skills:critical appraisal of the nurse’s role in infection control, literature searching, and academic writing and referencing.
Mary Smith, 21 years old, is admitted to the ward with an infected laceration on her left foot. Mary was at a beach resort four days ago, when she trod on a broken glass bottle and sustained a deep 2 cm long jagged laceration over the lateral aspect of her left foot. She used her handkerchief to bandage the wound. This morning the wound was extremely painful, swollen and had a discharge that had an unpleasant smell.
On inspection of the wound the following observations were made:
- Painful and gaping wound that felt warm when touched, with red and swollen edges.
- Purulent discharge.
A wound swab was taken for culture and sensitivity.A stat dose of ceftriaxone 1g was administered IVI immediately.
She was then commenced on oral cephalexin 500mg to be taken every 6 hours before being sent home.
Answer the following questions:
1.Describe the physiological basis for the appearance of Mary’s wound.
2.Explain TWO likely sources for the contamination of the wound and the mode of transmission of the microorganism from each source.
Culture and sensitivity test confirmed the microorganism infecting the wound to beStaphylococcus aureus. The drug cephalexin was discontinued and replaced with oral dicloxacillin 500 mg every 6 hours.
3.Explain the rationale for the initial choice of antibiotics, and then indicate why the subsequent change in antibiotic therapy. State any TWO common adverse reactions to dicloxacillin
4.Describe the process by which Mary’s wound will heal.
