Question 1 of 5
If both Insulin glargine (Lantus) and insulin lispro (Humalog) are due simultaneously, the nurse can mix the two insulins in the same syringe and administer them as one injection.
Correct Answer: B
Rationale: Mixing insulin glargine and lispro in the same syringe is contraindicated due to their incompatible chemical formulations. Glargine's acidic pH alters lispro's effectiveness when mixed, impairing glycemic control. Separate administration preserves their individual pharmacokinetics and therapeutic actions. Separate injections ensure each insulin maintains its unique action profile. Glargine provides basal control, while lispro manages rapid postprandial spikes. Their chemical incompatibility mandates separate administration, optimizing glycemic management and reducing potential adverse effects from mixed formulations.
