Choose the laboratory tests that you expect to be obtained preoperatively, and discuss the
rationale for your choices.
a. CHEM-7
b. Urinalysis
c. Stool sample for fat content
d. ABGs (arterial blood gases)
e. Complete blood count (CBC) with differential
a, b, e
The CHEM-7 will determine the fluid and electrolyte status of S.G. It is important to determine
whether she is dehydrated or has electrolyte imbalances. A urinalysis will reveal whether a patient
has a urinary tract infection and assesses renal function. The CBC is important to determine whether
hemoglobin and hematocrit are normal. Children who are adopted might have chronic malnutrition
and anemia, and this should be determined before surgery. In addition, the CBC will determine any
bleeding or immune disorders (platelets and WBCs). A stool sample and ABGs are not indicated.
