In a client with mononucleosis, which organ should not be palpated to avoid complications?

In a client with mononucleosis, the spleen should not be palpated because there is a significant risk of splenic enlargement (splenomegaly), which is a common complication associated with this viral infection. The spleen can become distended and very fragile during mononucleosis, making it susceptible to rupture. If palpated, there is a risk of this rupture occurring, which can lead to internal bleeding and potentially life-threatening complications.

While the liver, kidneys, and pancreas can also be considered in various pathological conditions, they do not carry the same urgent risk associated with palpating the spleen in this context. In cases of mononucleosis, it is particularly important to avoid any action that could compromise the integrity of an already vulnerable spleen. Thus, avoiding palpation of the spleen is critical for ensuring patient safety and preventing severe complications.
