1. Process through which bacteria develop resistance to antibiotics (2 marks):

Bacteria develop resistance to antibiotics through a process of natural selection. When a population of bacteria is exposed to an antibiotic, those that are sensitive to the drug will be killed off, leaving behind only those that have some form of resistance. These resistant bacteria then reproduce, passing on their resistance to their offspring. Over time, the population of bacteria becomes more and more resistant to the antibiotic. This process can be accelerated by the misuse and overuse of antibiotics, which provides more opportunities for resistance to develop. In the case of MRSA (Methicillin-resistant Staphylococcus aureus), the bacteria have developed resistance to methicillin and other common antibiotics, making infections difficult to treat.

2. Short-term and long-term effects on patient outcomes and healthcare costs (2 marks):

In the short term, antibiotic resistance can lead to longer hospital stays and increased mortality rates, as infections are harder to treat. This can also lead to increased healthcare costs, as more resources are needed to care for these patients. In the long term, if antibiotic resistance continues to rise, we could see a return to the pre-antibiotic era, where simple infections could be deadly. This would have a significant impact on healthcare costs, as more invasive and expensive treatments would be needed to deal with these infections.

3. Potential societal implications if antibiotic resistance continues to rise (2 marks):

If antibiotic resistance continues to rise, it could have serious societal implications. It could lead to a public health crisis, with increased mortality rates from common infections and diseases that were once easily treatable. This could also put a strain on healthcare systems, leading to increased healthcare costs. Furthermore, it could impact food production, as antibiotics are often used in agriculture. Finally, it could lead to increased social inequality, as those who can't afford the more expensive treatments needed to combat resistant infections would be disproportionately affected.
