A nurse is preparing to administer the antibiotic for a hospitalized patient who acquired a Methicillin-resistant Staph. aureus (MRSA) infection. Based on the nurses' knowledge of antibiotics for the treatment of MRSA, which medication may be ordered? Vancomycin Neomycin Cefazolin Ceftaroline Metronidazole Piperacillin Ans: Answer: Vancomycin and ceftaroline 2 | P a g e Rationale: Methicillin-resistant Staph. aureus(MRSA), highly resistant bacteria, are resistant to all penicillins and all cephalosporins. Because most strains of MRSA are multidrug resistant, many other antibiotics are ineffective, including tetracyclines, clindamycin, trimethoprim/sulfamethoxazole, and beta-lactam agents (except ceftaroline). Preferred drugs are IV vancomycin, linezolid [Zyvox], daptomycin [Cubicin], telavancin [Vibativ], clindamycin, and ceftaroline. See Lehne p. 1017 A patient who works as a landscaper is preparing to be discharged home. Ciprofloxacin (Cipro) has been prescribed for outpatient therapy. Which of the following will the nurse include in the discharge teaching for this patient? "You may take the medication with milk of magnesia." 3 | P a g e "Use sunscreen and protective clothing when outdoors." "Take the medication with crackers and cheese." "Take the medication until all symptoms subside." Ans: "Use sunscreen and protective clothing when outdoors." Rationale: The patient, a landscaper, should be advised to wear sunscreen and protective clothing when outdoors, because the medication may cause phototoxicity. The medication should be taken until it is gone, not just until the patient's symptoms are improved. Absorption of fluoroquinolones is reduced when taken with a number of products including aluminum or magnesium containing antacids and milk or other dairy products. See Lehne p. 1087 4 | P a g e A nurse transcribes a new prescription for potassium penicillin G given intravenously (IV) q 8 hours and gentamicin IV q 12 hours. Which plan is the best schedule for administering these drugs? a.) penicillin at 0800, 1600, and 2400; gentamicin at 1200 and 2400 b.) penicillin at 0600, 1400, and 2200; gentamicin at 0600 and 1800 c.) penicillin at 0800, 1600, and 2400; gentamicin at 0600 and 1800 d.) penicillin at 0100, 0900, and 1700; gentamicin at 0900 and 1800 Ans: Answer: C Rationale: Gentamicin should never be administered concurrently with penicillin, because they will interact, and the penicillin may inactivate the aminoglycoside. All options except A show concurrent administration. See Lehne p. 1064 5 | P a g e A patient has acquired hospital-associated MRSA. Which drug does the nurse anticipate will be ordered to treat this infection? vancomycin (Vancocin) TMP/SMZ (Bactrim) imipenem (Primaxin) azithromycin (Zithromax) Ans: Answer: Vancomycin Rationale: MRSA is resistant to all penicillins and cephalosporins. These include beta lactam antibiotics such as imipenem. Most strains of MRSA are also resistant to many other antibiotics. The drug of choice is vancomycin although there are others that may be used. 6 | P a g e TMP/SMZ is a preferred drug for community-acquired MRSA. Azithromycin is a macrolide used for respiratory and skin infections as well as other infections such as mycobacterium avium and chlamydia. A hospitalized patient is receiving gentamicin (Garamycin) 80 mg IV twice daily for acute osteomyelitis. Which data about the patient is most important for the nurse to obtain before administering the gentamicin? a.) oral temperature b.) reports of nausea c.)
