Question 32 1 out of 1 points Which of the following is critical to helping prevent development of resistant strains of microbes in patients? Response Feedback: Exposure to an antimicrobial agent leads to the development of resistance, so it is important to limit the use of these agents to the treatments of specific pathogens known to be sensitive to the drug being used. Drug dosages are also important in preventing the development of resistance. However, the duration of drug use is critical to ensure that microbes are completely eliminated and not given the chance to grow and develop resistant strains. It is hard to convince patients that the timing of the dose and length of time they continue to take the drug are important. Patients who stop the drug when they start to feel better encourage the emergence of resistant strains. Question 33 1 out of 1 points A 72-year-old patient is prescribed ophthalmic ciprofloxacin for a bacterial infection in her right eye. The nurse will teach her to observe for which of the following adverse effects of the drug? Response Feedback: Adverse reactions to ophthalmic ciprofloxacin usually involve local effects such as burning or discomfort. Other adverse effects of ophthalmic
ciprofloxacin are lid margin crusting, crystals, scales, foreign body sensation, pruritus, conjunctival hyperemia, and a bad taste in the mouth. Increased intracranial pressure and tendon ruptures are not identified adverse effects of ophthalmic ciprofloxacin. Nephrotoxicity and neurotoxicity are the primary adverse effects of polymyxin B. Question 34 1 out of 1 points A 7-year-old child has tonsillitis and is prescribed penicillin V, which is to be administered at home. The nurse will instruct the parents to administer the drug Response Feedback: The nurse should instruct the parents to administer penicillin V exactly as prescribed at regular intervals. Penicillin V should be taken on an empty stomach 1 hour before or 2 hours after a meal with a glass of water. Penicillin V should not be taken with meals because food may affect the absorption of the drug. Penicillin V is easy to administer in the home setting; it does not need to be given IV under the supervision of a home health nurse. Question 35 1 out of 1 points A patient is receiving long-term clindamycin therapy for a life-threatening infection. The nurse will begin by monitoring this drug therapy by obtaining Response Feedback: Patients on long-term clindamycin therapy should have a baseline complete blood count because of clindamycin's potential to induce blood dyscrasias. Blood sugar levels, auditory abilities, and liver enzymes need not to be evaluated for long-term or short-term therapy. Wednesday, July 19, 2017 10:32:20 PM EDT
