A nurse is reviewing the medication administration record of a client who has a wound infection. The client has prescriptions for cefotetan and an NSAID. The nurse should monitor for which of the following medication interactions?

Choice A rationale Jaundice, a yellow discoloration of the skin and sclera, indicates liver dysfunction or hemolysis. While some medications can cause hepatotoxicity, the combination of cefotetan and an NSAID does not primarily or commonly lead to jaundice through direct interaction mechanisms to warrant monitoring as the primary concern. Choice B rationale Dizziness can be a side effect of various medications but is not a specific or prominent interaction risk between cefotetan and NSAIDs. NSAIDs can cause dizziness, but the interaction with cefotetan primarily concerns other physiological systems, especially those related to coagulation. Choice C rationale Bleeding is a significant concern when NSAIDs are co-administered with certain antibiotics, including cefotetan. NSAIDs inhibit platelet aggregation by blocking cyclooxygenase, reducing thromboxane A2. Cefotetan, a second-generation cephalosporin, can also interfere with vitamin K metabolism, leading to hypoprothrombinemia, thus synergistically increasing the risk of hemorrhage. Choice D rationale Dysrhythmias, abnormal heart rhythms, are not a recognized primary interaction between cefotetan and NSAIDs. While certain medications can affect cardiac electrical activity, the interaction between these two drug classes is predominantly related to their impact on coagulation and gastrointestinal integrity.
