Final answer:
Suctioning should not be performed over skin that is infected, burned, or has open wounds, to avoid further injury, delay healing, and increase the risk of infection.
Step-by-step explanation:
When performing suctioning, one must be cautious not to suction over certain types of skin. Suctioning is contraindicated over skin that is infected, burned, or has open wounds. This is because such skin is already compromised and suctioning can lead to further injury, delay healing, and increase the risk of infection. Moreover, it's important to remember that while the skin is an important protective barrier, it does not provide complete protection against all foreign particles. The epidermis and underlying layers can be breached, especially in these compromised conditions, making the area even more susceptible to foreign invaders and further complications.
In simpler terms, avoid suctioning over skin that is not healthy and intact. The area should be free of signs of infection, which can include redness, swelling, warmth, and pus. Burns and open wounds should also be avoided because the protective layers of the skin are damaged, reducing its barrier effectiveness and increasing vulnerability. Respect these guidelines to prevent exacerbating any existing skin conditions or creating new complications.
