# Calculating Medication Doses with the Nursing Formula: A Simple Python Application

January 4, 2023•266 words

The nursing formula or the universal formula (or “desired over have method”), the desired amount (D) is the dose prescribed and the amount on hand (H) or the amount you “have” is the available dose or concentration. The quantity (Q) is the form and amount in which the drug is supplied (i.e. tablet, capsule, liquid).

Here is a simple Python application that demonstrates how to use the nursing formula to calculate the amount of a medication to administer:

```
def calculate_dose(D, H, Q):
return (D * Q) / H
```

```
#Example usage
dose = calculate_dose(100, 50, 2)
print(dose) # Output: 4
```

This application defines a function called calculate_dose that takes three arguments: the desired dose (D), the amount on hand (H), and the quantity (Q). The function returns the calculated dose using the nursing formula.

To use the function, you would simply call it with the appropriate values for D, H, and Q. In the example above, the function is called with D = 100, H = 50, and Q = 2, which means that the desired dose is 100 units, the amount on hand is 50 units, and the quantity is 2. The function returns a calculated dose of 4 units.

You can modify this application to fit your specific needs by adding additional features or functionality. For example, you might want to add error checking to make sure that the values for D, H, and Q are valid, or you might want to add a user interface to make it easier for users to enter and view the values.
