Quick answerThe correct matches are based on the pharmacological profiles and clinical administration requirements of each insulin product.
Why this is correctEach cue describes a clinical situation that aligns with the characteristics of a specific insulin product. For example, a clear basal insulin given once daily without mixing matches glargine, while a cloudy insulin requiring resuspension matches NPH.
Clinical pictureInsulin products differ in onset, peak, duration, appearance, and compatibility. Rapid-acting insulins like lispro are used for prandial coverage. Short-acting regular insulin can be given intravenously. Intermediate-acting NPH is a cloudy suspension. Long-acting glargine is clear and cannot be mixed with other insulins.
Memory hookRemember the mnemonic: 'Clear before cloudy' for drawing up insulins, and 'Glargine is clear and alone' for administration. NPH is the only cloudy insulin among the common products.
NCLEX decision ruleMatch insulin products to their clinical use: rapid-acting for meals, short-acting for IV use, intermediate-acting for twice-daily basal coverage with mixing, and long-acting for once-daily basal without mixing.
Why the alternatives are wrongIncorrect matches would result from confusing onset times (e.g., using lispro for basal coverage), mixing incompatible insulins (e.g., glargine with regular), or failing to recognize that NPH requires resuspension.
