Chapter 38 : Antibiotics Part 1 Questions
Question 1 of 5
A patient will be receiving amoxicillin suspension 300 mg via a gastrostomy tube every 8 hours. The medication comes in a bottle that contains 400 mg/5 mL. Identify how many milliliters the nurse will administer with each dose. (record answer using one decimal place)
Correct Answer: 3.8 mL
Rationale: 400 mg:5 mL::300 mg:x mL. Solve for x: (400 ?? x) = (5 ?? 300); 400x = 1500; x = 3.75, rounding to 3.8; administer 3.8 mL.
Question 2 of 5
A patient will be receiving penicillin G potassium, 12 million units daily in divided doses every 4 hours IVPB. Identify how many units the patient will receive for each dose each day.
Correct Answer: 2 million
Rationale: If a medication is given every 4 hours, then there will be 6 doses in each 24-hour day. (24 ?· 4 = 6). 12 million units ?· 6 doses = 2 million units/dose.
Question 3 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 4 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 5 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.
