Example Question #31 : Pharmacology
Which of the following is an appropriate reason to delay antibiotic administration in a stable patient?
A blood type and screen is not up to date
The patient is nauseated
A stool sample must be obtained first
A complete blood count has not been drawn today
Blood cultures must be obtained first
Blood cultures must be obtained first
Obtaining a set of blood cultures before treating a bacterial infection helps to individualize care and reduce antibiotic resistance (using a narrow-spectrum antibiotic doesn't work against so many types of bacteria). By identifying specific bacteria in the blood, a narrow-spectrum antibiotic may be chosen. A physician may prescribe a broad-spectrum antibiotic initially and change treatment later based on the results of the blood cultures.
Example Question #11 : Drug Administration And Distribution
The nurse is teaching a patient who has just been prescribed antibiotics. The nurse knows that teaching has been effective when the patient states which of the following?
"I should use a back-up method of birth control if I use oral contraceptives while taking antibiotics."
"An antibiotic will help me get over my case of the flu."
"My mother was previously prescribed the same antibiotic. I may take some of her leftover pills if my symptoms return."
"I can stop taking the antibiotics when I feel better."
"An antibiotic might help prevent me from getting sick in the future."
"I should use a back-up method of birth control if I use oral contraceptives while taking antibiotics."
Antibiotics may interfere with the function of oral contraceptives. A woman who is on oral contraceptives must use a back-up method of birth control to prevent pregnancy. Antibiotics should only be taken as prescribed. They should be taken continuously until all pills are gone. It is dangerous to take leftover antibiotics. Antibiotics will not prevent illness and do not work against viruses such as influenza. Misuse of antibiotics may contribute to antibiotic resistance and the rise of antibiotic resistant bacteria.
