The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for a urinary tract infection. Which action is most important prior to administering the antibiotic?
a. Administering a small test dose to determine whether hypersensitivity exists
b. Having epinephrine available in the event of a severe hypersensitivity reaction
c. Monitoring baseline vital signs, including temperature and blood pressure
d. Obtaining a specimen for culture and sensitivity
ANS: D
To obtain the most accurate culture, the specimen should be obtained before antibiotic therapy begins. It is important to obtain cultures when possible in order to correctly identify the organism and help determine which antibiotic will be most effective. Administering test doses to determine hypersensitivity is sometimes done when there is a strong suspicion of allergy when a particular antibiotic is needed. Epinephrine is kept close at hand when there is a strong suspicion of allergy.
