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

A patient would need 3 bottles of NPH insulin for a 60-day supply.

To calculate the total insulin requirement, first determine the daily dosage: 23 units in the morning plus 17 units in the evening equals 40 units per day. Over 60 days, this results in a total of 2400 units needed. Given that each bottle contains 1000 units, the patient would require 3 bottles to meet this demand.

A (2) YOUR ANSWER

If the patient were to receive only 2 bottles, that would total 2000 units (2 x 1000 units), which is insufficient for the required 2400 units over 60 days. This option does not meet the patient's needs.

B (3) CORRECT

This answer accounts for the total dosage calculated. With 3 bottles, the patient would have 3000 units (3 x 1000 units), which exceeds the required 2400 units, thus ensuring sufficient supply for the 60 days.

C (12) YOUR ANSWER

Twelve bottles would provide 12,000 units (12 x 1000 units), far exceeding the total requirement of 2400 units. While this option meets the need, it is impractically excessive and not the correct minimum number of bottles required.

D (24) YOUR ANSWER

Twenty-four bottles would yield 24,000 units (24 x 1000 units), which is also significantly more than necessary. Similar to option C, while it covers the requirement, it is unnecessarily high and not the optimal answer.

Conclusion

In summary, the patient requires 3 bottles of NPH insulin to adequately cover a 60-day supply based on their prescribed daily dosage. The calculations confirm that 2400 units are needed, making 3 bottles the correct and most efficient choice for their treatment.

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.
