"Cephalosporins prevent neuromuscular blockade associated with aminoglycosides." D. "Cephalosporins prolong the postantibiotic effects of the aminoglycosides so doses can be decreased."
A. "Cephalosporins enhance the actions of aminoglycosides by weakening bacterial cell walls."
A patient is prescribed an antibiotic to treat a urinary tract infection. What statement by the patient indicates a need for further teaching? A. "I can stop the medication as soon as the symptoms have disappeared." B. "I will drink more fluids to help clear up the infection." C. "I will stop the medication and contact the doctor if I develop a rash." D. "I should immediately report vaginal itching or discharge."

If at all possible, patients with penicillin allergy should not be treated with any member of the penicillin family. Use of cephalosporins depends on the intensity of the allergic response to penicillin; if the penicillin allergy is mild, use of cephalosporins is probably safe. However, if the allergy is severe, cephalosporins should be avoided.

B. Metformin
A patient is diagnosed with C. difficile infection. The nurse anticipates administering which medication? A. Daptomycin B. Metronidazole C. Rifampin D. Rifaximin
B. Metronidazole Metronidazole is a drug of choice for C. difficile infection. Daptomycin has a unique mechanism and can rapidly kill virtually all clinically relevant gram-positive bacteria, including MRSA. Rifampin [Rifadin] is a broad-spectrum antibacterial agent used primarily for tuberculosis. However, the drug is also used against several nontuberculous infections. Rifampin is useful for treating asymptomatic carriers of Neisseria meningitidis. Rifaximin [Xifaxan] is an oral, nonabsorbable analog of rifampin used to kill bacteria in the gut.

B. Skin rash, hives, or itching Hypersensitivity reactions are common with cephalosporins. Patients should be instructed to report any signs of allergy, such as skin rash, itching, or hives. Cefditoren contains a milk protein and should not be prescribed for patients with a milk protein allergy. Cefoperazone and cefotetan can promote bleeding. Diarrhea associated with antibiotic-associated pseudomembranous colitis (AAPMC) is a possible side effect with cephalosporins.

Serum creatinine and blood urea nitrogen levels B. Trough drug levels of gentamicin C. Peak drugs levels of gentamicin D. Serum alanine aminotransferase and aspartate aminotransferase levels
B. Trough drug levels of gentamicin To minimize ototoxicity, trough levels must be sufficiently low to reduce exposure of sensitive sensory hearing cells. The risk of ototoxicity is related primarily to persistently elevated trough drug levels rather than to excessive peak levels.
A patient develops CDAD. Which antibiotic is recommended for treating this infection? A. Clindamycin [Cleocin] B. Vancomycin C. Chloramphenicol D. Linezolid [Zyvox]
B. Vancomycin
A patient has been prescribed oral ciprofloxacin [Cipro] for a skin infection. When administering the medication, it is most important for the nurse to do what? A.

Inform the healthcare provider if the patient has a history of asthma D. Assess the skin for Stevens-Johnson syndrome
B. Withhold antacids and milk products for 6 hours before or 2 hours afterward Absorption of ciprofloxacin can be reduced by ingestion of antacids and milk products. Ingestion of these products should occur at least 6 hours before ciprofloxacin or 2 hours afterward. Ciprofloxacin can increase the PT if the patient is also taking warfarin. Use of ciprofloxacin is contraindicated in patients with a history of myasthenia gravis. Patients taking ciprofloxacin are at risk for development of phototoxicity.
A 65-year-old patient who receives glucocorticoids for arthritis is admitted to the hospital for treatment of a urinary tract infection. The prescriber has ordered intravenous ciprofloxacin [Cipro].

Rifampin is toxic to the liver, posing a risk of jaundice and even hepatitis. Asymptomatic elevation of liver enzymes occurs in about 14% of patients. However, the incidence of overt hepatitis is less than 1%. Hepatotoxicity is most likely in alcohol abusers and patients with pre-existing liver disease. These individuals should be monitored closely for signs of liver dysfunction.
