How many days would a bottle of Humulin N 10 mL last a patient using 28 units in the morning and 8 units in the evening?
A bottle of Humulin N 10 mL would last 27 days for a patient using 28 units in the morning and 8 units in the evening.
To determine how long the bottle lasts, first calculate the total daily usage of insulin. The patient uses 28 units in the morning and 8 units in the evening, resulting in a total of 36 units per day. With a 10 mL bottle, which contains 1000 units of insulin (since 1 mL contains 100 units), the bottle would last approximately 27 days.
This choice is incorrect as it suggests that the bottle would last only 3 days. Given that the total daily usage is 36 units, a 10 mL bottle containing 1000 units would last significantly longer than just 3 days.
This option also miscalculates the duration. Using 36 units per day, a 10 mL bottle would last for approximately 27 days, not just 10 days, making this choice inaccurate.
This is the correct answer. With a total consumption of 36 units per day, the 10 mL bottle (or 1000 units) would last for 27 days, calculated by dividing 1000 units by 36 units/day.
This choice is misleading as it overestimates the duration the bottle would last. At a usage of 36 units daily, the 10 mL bottle would not last for 30 days; it would run out sooner, specifically in 27 days.
Understanding the dosage calculation is essential for managing insulin effectively. In this scenario, with a total daily intake of 36 units calculated from both morning and evening doses, the 10 mL bottle of Humulin N, containing 1000 units, would indeed last 27 days. This highlights the importance of precise dosage management for patients relying on insulin therapy.
