Answer:
The best example of the chain of infection from the given options is B. "I once got very sick from sitting next to a lady at the park who was coughing."
Explanation:
The chain of infection refers to the process through which infections are transmitted from one person to another. It typically involves a series of events or links that must be present for an infection to occur. These links include:
1. Infectious agent: The coughing lady in this example represents the infectious agent, as she was likely carrying a respiratory infection that can spread through respiratory droplets.
2. Reservoir: The coughing lady's respiratory system serves as the reservoir, where the infectious agent is harbored and can be transmitted to others.
3. Portal of exit: When the coughing lady coughs, she releases respiratory droplets containing the infectious agent, which act as the portal of exit.
4. Mode of transmission: In this case, the mode of transmission is direct contact, as the person writing the example got sick from sitting next to the coughing lady.
5. Portal of entry: The person's respiratory system is the portal of entry, as they inhale the respiratory droplets containing the infectious agent.
6. Susceptible host: The person who got sick from sitting next to the coughing lady represents the susceptible host, as they were susceptible to contracting the infection.
This example demonstrates how the chain of infection can be initiated by an infectious agent, transmitted through direct contact, and result in illness in a susceptible host. It illustrates the importance of taking precautions to prevent the spread of infections, such as covering the mouth while coughing and practicing good respiratory hygiene.

It is not necessary to wear sunscreen during recreational activities when it is indoors. Therefore, option D is correct.
Sunscreen shields keep skin safe. They are crucial in preventing the skin from absorbing ultraviolet (UV) radiation. Sunburns and skin cancer are both caused by UV radiation, which also affects the skin.
Your elastin, collagen, and skin cells can become damaged from repeated sun exposure with little to no protection. This can eventually result in early ageing symptoms such as discolouration, wrinkles, fine lines, and a leathery appearance. People who spend time in the sun without protection, especially those in their 20s and 30s, are more likely to experience photoaging, or premature ageing. Thankfully, consistent sunscreen use can avoid these skin problems.
It is not necessary to wear sunscreen when recreational activities are indoors and at night. Therefore, option D is correct.

Explanation:
Brachytherapy is a type of cancer radiation therapy/ treatment which involves the placement of radioactive material within specific regions of the body. This maybe utilized to deliver more specific cancer treatments in affected areas. Available within higher doses in comparison to whole body radiation treatments.
Bone density tests called DEXA (dual energy x-ray) scans measure the bones density by focusing on specific regions namely the spine and hip bones This diagnoses and can even determine a person's risk of developing developing osteoporosis which is a condition in which the bones are weakened and fragile
The test uses small doses of ionizing radiation (X-rays) to provide internal scans.
DXAs are also used prior to cancer treatment in order to potentially diagnose cancer present in the bone and to monitor bone health throughout treatment uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower (or lumbar) spine and hips) to measure bone loss.

DXA, which measures bone density, should be completed before brachytherapy to evaluate the risk of radiation-related bone damage. This step aids in developing a safe and effective treatment plan.
The DXA (Dual-energy X-ray Absorptiometry) should be completed before brachytherapy because DXA is used for bone density measurement. Brachytherapy, on the other hand, is a type of radiotherapy where a sealed radiation source is placed inside or next to the area requiring treatment. Before implementing brachytherapy, especially when the pelvic area or prostate is involved, a DXA scan is necessary to measure the bone density and evaluate the risk of radiation-related bone damage. This precautionary measure is essential for developing an effective and safe treatment plan.
