Final answer:
An exanthematous (morbiliform) drug eruption does not typically have a severe systemic impact, as these are usually self-limited skin reactions. Allergies and autoimmune diseases are true examples of an over-reactive immune system. Symptoms like fluid blisters and respiratory distress warrant urgent care due to the potential for severe complications.
Step-by-step explanation:
The statement that an exanthematous (morbiliform) drug eruption has a severe systemic impact is typically considered false. Exanthematous or morbiliform drug eruptions generally present as widespread red rashes that may resemble measles, which is why they are also called measles-like rashes. While they can be uncomfortable and may require medical attention, these eruptions are often self-limited and not usually associated with severe systemic symptoms. However, it is essential to differentiate them from other conditions that could have a more significant systemic impact, such as Stevens-Johnson syndrome or toxic epidermal necrolysis, which are severe skin reactions that also involve systemic symptoms and can be life-threatening.
True or false: Allergies and autoimmune diseases both result from an over-reactive immune system. This statement is true; both allergies and autoimmune diseases are characterized by an immune system that inappropriately reacts to substances in the case of allergies, or to the body's own tissues in the case of autoimmune diseases.
Severe symptoms such as skin erythema with fluid blisters, mucosal pain, and respiratory distress may indicate more serious conditions and require immediate medical attention, as they can lead to complications such as infections, scarring, or systemic involvement.
