A nurse is preparing to administer ceftriaxone (Rocephin) to a client who has bacterial meningitis.
The nurse should recognize that this medication is effective against which type of bacteria?
Gram-positive
Gram-negative
Anaerobic
Aerobic.
The Correct Answer is B
Ceftriaxone (Rocephin) is a third-generation cephalosporin antibiotic that works by interfering with the formation of bacterial cell walls. It is effective against gram-negative bacteria, such as Neisseria gonorrhoeae and Haemophilus species, which are common causes of bacterial meningitis.
Choice A is wrong because ceftriaxone is less active against gram-positive bacteria, such as Staphylococcus and Streptococcus species.
Choice C is wrong because ceftriaxone is not effective against anaerobic bacteria, which are bacteria that do not require oxygen to grow. Anaerobic bacteria are usually treated with metronidazole or clindamycin.
Choice D is wrong because ceftriaxone can treat both aerobic and anaerobic gram-negative bacteria, but not all aerobic bacteria are gram-negative.
Aerobic bacteria are bacteria that require oxygen to grow. Some examples of aerobic gram-positive bacteria are Listeria monocytogenes and Bacillus anthracis, which are resistant to ceftriaxone.

Correct Answer is A
Explanation
Warfarin (Coumadin) can interact with metronidazole (Flagyl) and increase the risk of bleeding.This is because metronidazole may inhibit the enzyme that metabolizes warfarin, leading to higher warfarin levels and enhanced anticoagulant effect.If a patient is taking warfarin and metronidazole, they may need a dose adjustment and frequent monitoring of their INR.They should also watch for any signs of bleeding or bruising and report them to their doctor.
Choice B is wrong because levothyroxine (Synthroid) does not have a significant interaction with metronidazole.
Choice C is wrong because lisinopril (Prinivil) does not have a significant interaction with metronidazole.
Choice D is wrong because omeprazole (Prilosec) does not have a significant interaction with metronidazole.
