1. Conductive hearing loss involves the middle ear and is usual-
inner ear ly the result of one of the
middle ear following: blockage of the
5th cranial nerve ear canal, a hole in the
8th cranial nerve ear drum, problems with
three small bones in the
ear, or fluid in the space
between the ear drum and
cochlea

2. A 30-day-old infant presents to the emergency room relative deficiency of factor
with decreased oral intake, decreased urine output, B
and a fever of 101.8. The infant is admitted for further
evaluation with a workup to include a blood culture, a
urine culture, a spinal tap, and a chest X-ray.
Which issue of innate immunity, as it relates to
neonates, is of concern?
dysfunctional chemotactic factor response
excess collectin and collectin like protein
relative deficiency of factor b
high levels of mannose

3. 12-year-old African American patient presents with C1 esterase inhibitor
unilateral eye swelling and lower lip swelling. The pa-
tient'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.
C1 esterase inhibitor
Plasminogen

, Bradykinin
Hageman factor

the skin, triggered by an
allergy to animal dan-
der, pollen, drugs, venom,
food, or medication.

istered nurse (APRN). The infections have occurred
regularly since birth.
What should the APRN tell the parent is the underlying
cause of this illness?
Hyperthyroidism causes an increased risk of infec-
tion.
Gastroesophageal reflux disease causes aspiration of
thin fluids.
Short stature causes poor lung development.
Hypertonia causes airway restriction.

pressed due to a major life change. Additional symp-
toms include weight gain, sedentary activity, and in-
somnia. The APRN plans on providing the patient with
