HESI Dosage Calculations Practice Test
The HESI Dosage Calculations Practice Test is a comprehensive assessment designed to evaluate nursing students’ proficiency in performing dosage calculations. This test is typically administered as part of the HESI Admission Assessment Exam (HESI A2), which is used by many nursing schools for admission purposes.
The HESI Dosage Calculations Practice Test consists of 25 multiple-choice questions that cover a wide range of dosage calculation concepts and methods. These questions are designed to assess students’ understanding of the following areas:
- Units of measurement
- Medication forms
- Calculation methods
- Dimensional analysis
- Ratio and proportion
- Formula methods
Students who are preparing for the HESI Dosage Calculations Practice Test should focus on developing a strong understanding of these concepts and practicing solving dosage calculation problems using various methods.
Dosage Calculation Concepts
Dosage calculations involve converting the prescribed dose of a medication into the appropriate amount to be administered to a patient. To perform dosage calculations accurately, it is essential to understand the following concepts:
Units of Measurement, Hesi dosage calculations practice test
Medications can be measured in a variety of units, including milligrams (mg), grams (g), micrograms (mcg), and milliliters (mL). It is important to understand the relationships between these units and to be able to convert between them.
Medication Forms
Medications can be administered in various forms, including tablets, capsules, liquids, and injections. The form of the medication will affect the way it is dosed.
Calculation Methods
There are several different methods that can be used to perform dosage calculations. The most common methods include:
- Dimensional analysis
- Ratio and proportion
- Formula methods
The choice of which method to use will depend on the specific problem being solved.
Methods for Dosage Calculations
The following are the three main methods used for dosage calculations:
Dimensional Analysis
Dimensional analysis is a method of solving dosage calculation problems by using the units of measurement to guide the calculations. This method involves setting up a series of equations that convert the prescribed dose into the desired amount to be administered.
Ratio and Proportion
Ratio and proportion is a method of solving dosage calculation problems by using ratios and proportions to find the unknown amount. This method involves setting up a proportion that compares the prescribed dose to the desired amount to be administered.
Formula Methods
Formula methods involve using a specific formula to calculate the desired amount of medication to be administered. These formulas are typically provided in the medication’s package insert or in a drug reference book.
Practice Problems and Solutions
| Problem | Answer | Solution |
|---|---|---|
| A patient is prescribed 500 mg of acetaminophen every 6 hours. The available acetaminophen tablets are 325 mg each. How many tablets should the patient take each dose? | 2 | 500 mg / 325 mg/tablet = 1.53 tabletsRound up to 2 tablets |
| A patient is prescribed 1 g of vancomycin every 12 hours. The available vancomycin injection is 500 mg/mL. How many mL of vancomycin should be administered each dose? | 2 | 1 g = 1000 mg
|
| A patient is prescribed 2 mg/kg of morphine every 4 hours. The patient weighs 75 kg. How many mg of morphine should be administered each dose? | 150 | 2 mg/kg x 75 kg = 150 mg |
