A patient who is receiving immunotherapy has just received an allergen injection. Which assessment finding is most important to communicate to the health care provider?
a. The patient's IgG level is increased.
b. The injection site is red and swollen.
c. The patient's allergy symptoms have not improved.
d. There is a 2-cm wheal at the site of the allergen injection.
ANS: D
A local reaction larger than quarter size may indicate that a decrease in the allergen dose is needed. An increase in IgG indicates that the therapy is effective. Redness and swelling at the site are not unusual. Because immunotherapy usually takes 1 to 2 years to achieve an effect, an improvement in the patient's symptoms is not expected after a few months.
