[{'content': 'The antibiotic that may accentuate the neuromuscular blockade produces by d-tubocurarine is: \nSelect and explain. \nA. Penicillin G, B. Erythromycin, C. Streptomycin, D. Chloramphenicol', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Streptomycin inhibits acetylcholine release from the preganglionic terminal (through competition with\xa0 calcium) and reduces the post-junctional membrane sensitivity to acetylcholine, thus produce neuromuscular blockade.\xa0\nTetracycline antibiotics chelate calcium thus produce neuromuscular blockade.\xa0\nOther antibiotics that have neuromuscular blocking action include polymyxin B, colistin, clindamycin and lincomycin through pre and postsynaptic actions.\xa0\nThere are no reports of neuromuscular blockade produced by penicillin G, erythromycin and chloramphenicol.', 'role': 'assistant'}]
