Chapter 38 : Antibiotics Part 1 Questions
Question 1 of 5
During drug therapy for pneumonia, a female patient develops a vaginal superinfection. The nurse explains that this infection is caused by which of these?
Correct Answer: A
Rationale: Normally occurring bacteria are killed during antibiotic therapy, allowing other flora to take over and resulting in superinfections.
Question 2 of 5
The nurse is preparing to use an antiseptic. Which statement is correct regarding how antiseptics differ from disinfectants?
Correct Answer: D
Rationale: Antiseptics primarily inhibit microorganisms but do not necessarily kill them. They are applied exclusively to living tissue. Disinfectants are able to kill organisms and are used only on nonliving objects.
Question 3 of 5
A patient with a long-term intravenous catheter is going home. The nurse knows that if the patient is allergic to seafood, which antiseptic agent is contraindicated?
Correct Answer: C
Rationale: Iodine compounds are contraindicated in patients with allergies to seafood.
Question 4 of 5
During antibiotic therapy, the nurse will monitor closely for signs and symptoms of a hypersensitivity reaction. Which of these assessment findings may be an indication of a hypersensitivity reaction? (Select all that apply.)
Correct Answer: A,C,D,E
Rationale: Hypersensitivity reactions may be manifested by wheezing; shortness of breath; swelling of the face, tongue, or hands; itching; or rash. Diarrhea and black, hairy tongue are not typically associated with hypersensitivity reactions but may be other side effects of antibiotic therapy.
Question 5 of 5
The nurse is reviewing the medication history of a patient who will be taking a sulfonamide antibiotic. During sulfonamide therapy, a significant drug interaction may occur with which of these drugs or drug classes? (Select all that apply.)
Correct Answer: B,C,E,F
Rationale: Sulfonamides may potentiate the hypoglycemic effects of sulfonylureas in diabetes treatment and the toxic effects of phenytoin. They also enhance the anticoagulant effects of warfarin, which can lead to hemorrhage. Sulfonamides may also reduce the efficacy of oral contraceptives. Opioids and antihistamines are not typically associated with significant interactions with sulfonamides.
