Calculating parenteral feedings: a programmed instruction

A programmed learning tool on how to calculate and use parenteral feedings is presented. The format includes a brief text (frame), then questions and answers about the text. The 42 frames provide the reader a step-by-step explanation of (a) when parenteral feedings are used; (b) the differences between central and peripheral administration; (c) the calculation of nutrient needs, including calories, protein, carbohydrate, fat, fluids, vitamins, and minerals; (d) the percent solutions of those nutrients available and their caloric value; (e) the calculation of the solution osmolarity; and (f) the integration of the nutrients needed into the composition of the parenteral solution for the patient. The programmed instruction gives readers the basic framework for beginning their use of parenteral nutrition.
