The nurse is preparing to contact the physician for an antibiotic order for the patient's infection. What information will the nurse be prepared to provide for the physician to choose the proper antibiotic?
A) First day of infection symptoms
B) Culture and sensitivity test results
C) The patient's intake and output for past 2 days
D) Results of complete blood count with differential
B
Feedback:
Antibiotics are best selected based on culture results that identify the type of organism causing the infection and sensitivity testing that shows what antibiotics are most effective in eliminating the bacteria. First day of symptoms of infection is likely already known if culture and sensitivity testing has been performed. Although measurement of intake and output is one indicator of renal function, a blood–urea–nitrogen test and assessment of creatinine levels would be better ways of assessing renal function, which will be used to determine dose of medication but not for selection of the correct antibiotic. The white blood cell count and differential would indicate the possibility of an infection but are not needed in choosing the proper antibiotic.
