Samatha, age 4, has a glucose level of 329mg/dl. She is eating the following for lunch: grilled chicken, juice(15g carb), mashed potatoes (30g carb), applesauce (15g carb). Her insulin order is as follows: Provide insulin coverage for meals at 1 unit novolog/1 carbohydrate exchange (15g carb=1 carb exchange) and, Provide insulin correction for blood glucose level based on scale: Up to 249mg/dl: no correction 250-299 mg/dl: 0.5 unit novolog 300-349 mg/dl: 1 unit novolog 350-399 mg/dl: 1.5 unit novolog How much total insulin should Samantha receive?

A. Carbohydrate coverage: Samantha's meal includes 60g of carbs, which is 4 carb exchanges (60g ÷ 15g). She needs 4 units of Novolog for the carbohydrates. Correction dose: Since her glucose level is 329mg/dl, it falls within the 300-349mg/dl range, so she needs 1 unit of Novolog for correction. Total insulin = 4 units (meal coverage) + 1 unit (correction) = 5 units Novolog. B. 5.5 units novolog: This would be incorrect because it adds an extra 0.5 units without a clear justification based on either the carbohydrate coverage or the blood glucose correction scale. C. 4 units novolog: This is incorrect because it only accounts for the insulin needed to cover the carbohydrates in the meal and does not include the necessary 1-unit correction for her elevated blood glucose level. D. 2.5 units novolog: This is incorrect as it significantly underestimates the insulin needed for both meal coverage and blood glucose correction. It doesn't accurately reflect either the carbohydrate content of the meal or the correction needed based on the provided scale.
