A 12-year-old African American patient presents with unilateral eye swelling
and lower lip swelling. The patient's parent reports that the swelling is
spontaneous and resolves over several days. The patient does not have
complaints of fever, hives, or vomiting. Serum lab results show hyperactivation
of three plasma protein systems. The APRN suspects hereditary angioedema.
What is the cause of the genetic defect suspected in this situation? - Ans✔✔-
C1 esterase inhibitor
The parent of a child diagnosed with Down syndrome expresses concerns
about the child's recurrent respiratory tract infections to an advanced practice
registered nurse (APRN). The infections have occurred regularly since birth.
What should the APRN tell the parent is the underlying cause of this illness? -

gain, sedentary activity, and insomnia. The APRN plans on providing the patient
with several exercises to reduce the physiological effect of stress.
