normal circumstances. Monitoring the site of injection and continuing therapy until 2 days after the symptoms have resolved would represent good general nursing practice. Question 14 1 out of 1 points A patient has been prescribed oral tetracycline. The nurse will instruct the patient to take the drug Response Feedback : Oral preparations of tetracycline should be administered on an empty stomach 1 hour before or 2 hours after taking a meal or other drugs to maximize absorption. Tetracycline is not absorbed effectively if taken with food or dairy products. The dosage must be distributed around the clock, and not just at bedtime, to increase effectiveness. Question 15 1 out of 1 points
Mr. Laird is a 49-year-old electrician who experienced severe burns on his trunk, arms, and hands in a workplace accident 2 weeks ago. Part of his current wound care regimen involves the daily application of silver sulfadiazine to his wounds. The nurses who are providing care for Mr. Laird in the burns and plastics unit of the hospital should perform what action when administering this medication? Response Feedback : Before applying silver sulfadiazine, it is necessary to cleanse the wound completely and remove dead or burned skin and other debris. It would be inappropriate to perform wound care after the application of the drug and it should be applied in a thin layer no more than about 1/16 inch. Application of topical sulfonamides is a sterile, not clean, procedure. Question 16 1 out of 1 points A nurse is instructing a colleague on how an antimicrobial produces a therapeutic effect. Which of the following should be included in the nurse's teaching? Response Feedback : The action of antimicrobials is to interfere with the normal function of the invading organism to prevent it from reproducing and to cause cell death without affecting host cells. Penicillin interferes with biosynthesis of the bacterial cell wall. Because bacteria cells have a slightly different composition than human cells, the bacteria are destroyed without interfering with the host. The first drugs used to treat systemic infections were developed in the early 20th century. Fluoroquinolones act by interfering with DNA synthesis. Sulfonamides interfere with growth and development of bacterial cells. The term selective toxicity refers to the ability to affect certain proteins or enzyme systems that are used by infecting organisms but not by human cells.
