Clients with impaired immune systems are at __________ risk of infection should they encounter pathogens.

Clients with impaired immune systems are at a very high risk of infection if they encounter pathogens because their bodies are less capable of defending against harmful microorganisms. The immune system plays a crucial role in identifying and neutralizing pathogens such as bacteria, viruses, fungi, and parasites. When an individual's immune response is compromised due to factors like chronic illness, medications (such as immunosuppressants), or medical treatments (like chemotherapy), they are unable to mount an effective defense against infections.

This heightened vulnerability means that even common pathogens that might not pose a significant threat to healthy individuals can cause serious illness in those with weakened immune systems. Understanding this risk is essential for healthcare providers to implement appropriate infection control measures, ensuring that these clients receive the necessary precautions to minimize their exposure to infectious agents.
