Final answer:
The patients who would be at greatest risk in a healthcare visit are the elderly with multiple chronic conditions, pregnant women, and children with a common cold.
Step-by-step explanation:
The patients who would be at greatest risk in a healthcare visit are the elderly with multiple chronic conditions, pregnant women, and children with a common cold.
The elderly with multiple chronic conditions are at greater risk due to their weaker immune systems and higher likelihood of developing severe complications from infections.
Pregnant women are also at greater risk because pregnancy puts stress on the immune system and can make them more susceptible to infections. Additionally, certain infections can be harmful to the developing fetus.
Children with a common cold are more vulnerable to complications because their immune systems are still developing and they may not be able to effectively fight off the infection on their own.
