Answer to Question 1

Ans: D
Feedback:
When digoxin interacts with tetracyclines, the patient is at risk for digoxin toxicity. Respiratory depression is an effect observed when neuromuscular blocking drugs interact with lincosamides. A decrease in the effectiveness of tetracycline is seen when the drug is taken with antacids, dairy products, or iron. An increased risk for bleeding with prolonged clotting times is noted when tetracycline is given with anticoagulants.

Answer to Question 2

Ans: C
Feedback:
Quinupristin/dalfopristin is irritating to the vein. After peripheral infusion, the vein should be flushed with 5 dextrose in water (D5W), because the drug is incompatible with saline or heparin flush solutions.
