Chapter 38 Questions
Question 1 of 5
When reviewing the allergy history of a patient, the nurse notes that the patient is allergic to penicillin. Based on this finding, the nurse would question an order for which class of antibiotics?
Correct Answer: C
Rationale: Allergy to penicillin may also result in hypersensitivity to cephalosporins. Patients reporting penicillin allergy need to describe their prior allergic reaction. It is very important to document the type of reaction.
Question 2 of 5
The nurse is providing teaching to a patient taking an oral tetracycline antibiotic. Which statement by the nurse is correct?
Correct Answer: A
Rationale: Drug-related photosensitivity occurs when patients take tetracyclines, and it may continue for several days after therapy. Milk and cheese products result in decreased levels of tetracycline when the two are taken together. Antacids also interfere with absorption and should not be taken with tetracycline. Counsel patients to take the entire course of prescribed antibiotic drugs, even if they feel that they are no longer ill.
Question 3 of 5
When reviewing the medication orders for a patient who is taking penicillin, the nurse notes that the patient is also taking the oral anticoagulant warfarin. What possible effect may occur as the result of an interaction between these drugs?
Correct Answer: A
Rationale: Administering penicillin reduces the vitamin K in the gut (intestines); therefore, enhanced anticoagulant effect of warfarin may occur.
Question 4 of 5
A patient is receiving his third intravenous dose of a penicillin drug. He calls the nurse to report that he is feeling anxious and is having trouble breathing. What will the nurse do first?
Correct Answer: C
Rationale: Hypersensitivity reactions are characterized by wheezing; shortness of breath; swelling of the face, tongue, or hands; itching; or rash. The nurse should immediately stop the antibiotic infusion, have someone notify the prescriber, and stay with the patient to monitor the patient's vital signs and condition. Checking for allergies should have been done before the infusion.
Question 5 of 5
A patient is admitted with a fever of 102.8?°F (39.3?°C), origin unknown. Assessment reveals cloudy, foul-smelling urine that is dark amber in color. Orders have just been written to obtain stat urine and blood cultures and to administer an antibiotic intravenously. The nurse will complete these orders in which sequence?
Correct Answer: D
Rationale: All culture specimens should be obtained before initiating antibiotic drug therapy; otherwise, the presence of antibiotics in the tissues may result in misleading culture and sensitivity results.
