How many bottles of NPH insulin would a patient need for a 60 day supply, given the following directions? Inject subcutaneously 23 units every morning and 17 units in the evening.

Rationale

To provide a 60-day supply, a patient would need 3 bottles of NPH insulin.

The total insulin required for 60 days can be calculated by adding the daily morning and evening doses, and then multiplying by the number of days. This results in a total requirement that can be fulfilled by purchasing three bottles of insulin.

A (2) YOUR ANSWER

Choosing 2 bottles would not meet the patient's total insulin requirement. When calculating the total units needed over 60 days, the patient requires more than what 2 bottles can provide based on the daily dosage.

B (3) CORRECT

This option is correct. The patient requires 23 units in the morning and 17 units in the evening, totaling 40 units per day. Over 60 days, this amounts to 2,400 units. If each bottle contains 1,000 units, three bottles will provide the necessary total of 3,000 units, ensuring the patient has enough insulin for the duration.

C (12) YOUR ANSWER

Selecting 12 bottles greatly exceeds the required amount for a 60-day supply. While it ensures that the patient has an ample supply, it is unnecessary and inefficient, as the calculated need is significantly lower.

D (24) YOUR ANSWER

This choice also significantly exceeds the patient's requirement. With 24 bottles, the total units provided would far surpass the 2,400 units needed for a 60-day supply, leading to excessive waste and cost.

Conclusion

Calculating the total units of NPH insulin needed for a 60-day supply shows that 3 bottles will adequately cover the patient's dosage requirements. Each incorrect option either underestimates or grossly overestimates the amount needed, highlighting the importance of accurate dosage calculations in medication management.
