Answer to Question 1

a. Estimate: The concentration is or 2 mL for each unit; therefore, the flow rate estimate is 8 mL per hour.
b.
c. Equation is balanced. Estimate supports answer. Only mL per hour remain.
d. Regular insulin products and insulin lispro (Humalog) may be administered intravenously. Intermediate, long-acting, mixed insulins, and insulin aspart (NovaLog) cannot be adminis-tered intravenously due to additives.

Answer to Question 2

a. Estimate: 6 mL per hour
b.
c. Equation is balanced. Only mL per hour remains. Note: If the concentration is 1:1, such as 100 mL, mL per hour will equal the ordered units per hour.
d. Dextrose is needed to elevate blood glucose levels. Diet beverages contain dextrose substi-tutes, which do not affect blood glucose promptly or adequately.
