Read the following problem and see if<br />
it can help you figure out your basalbolus<br />
questions. Sam takes 19 units of<br />
insulin glargine (Lantus ®) at bedtime and<br />
insulin boluses of insulin lispro (Humalog)<br />
in the following amounts: 10 units for<br />

dinner. His mealtime carb amounts are 75<br />
at breakfast; 60 at lunch; and 100 grams<br />
at dinner. His insulin/carb ratio is 8:1 and<br />
his correction dose is 1 unit for every 50<br />
mg/dl and his target glucose is 100 mg/dl.<br />
On days 1-3 he always eats his normal<br />
amount of carb. He does not eat an<br />
afternoon snack. Look at his blood glucose<br />
values and insulin doses in the chart below.<br />
2. Which of the following types of<br />
problems does Sam have?<br />
A. A basal problem?<br />
B. A bolus problem?<br />
C. An eating problem?<br />
3. What should Sam do?<br />
