Chapter 38 : Antibiotics Part 1 Questions
Question 1 of 5
A patient will be having oral surgery and has received an antibiotic to take for 1 week before the surgery. The nurse knows that this is an example of which type of therapy?
Correct Answer: B
Rationale: Prophylactic antibiotic therapy is used to prevent infection. Empiric therapy involves selecting the antibiotic that can best kill the microorganisms known to be the most common causes of an infection. Definitive therapy occurs once the culture and sensitivity results are known. Resistance is not a type of antibiotic therapy.
Question 2 of 5

Therefore, they are often used in the treatment of urinary tract infections.
Question 3 of 5

Question 4 of 5
