A nurse was instructed by a physician to give clarithromycin
(Biaxin) for a child whose BSA is 0.55 m2. The usual adult dose is
500 mg. Biaxin is available in an oral suspension. The 100ml bottle
is labeled 50 mg/ml. How many ml would the nurse give per dose?
Fill in the blanks. Record your answer using one decimal place.
Answer: (3.2) mL.
Incorrect
Correct
answer:
3.2 mL.
Formula: BSA
Formula: BSA Formula:
Rationale:
Use the BSA formula first then the standard formula as
shown above.
To get the childʼs dose, multiply 0.55m2(childʼs BSA) to
500 mg (usual adult dose) to get 275.
Divide 275 with 1.7 m2to get 161.76
mg. Use the standard formula above.
Divide 161.76 mg (desired pedia dose) with 50 mg (drug
on hand) and multiply by 1 ml (vehicle) to get 3.2 ml.

unnecessary. A computerized tomography (CT) scan
combines a series of X-ray images taken from different
angles around the body and uses computer processing
to create cross-sectional images (slices) of the bones,
blood vessels, and soft tissues inside the body. CT scan
images provide more detailed information than plain X-
rays do.
Option C: A blood culture test helps the doctor figure out
if the client has a kind of infection that is in the
bloodstream and can affect the entire body. Doctors call
this a systemic infection. The test checks a sample of
the blood for bacteria or yeast that might be causing the
infection.
Option D: An arterial blood gas (ABG) test measures
oxygen and carbon dioxide levels in the blood. It also
measures the bodyʼs acid-base (pH) level, which is
usually in balance when healthy.
