Problem Statement: Salbutamol Dosage Calculation
Our problem involves a child who weighs 15 kg and requires a salbutamol dosage of 15 micrograms/kg. We have a salbutamol solution with a concentration of 0.5 mg per 5 ml. The question we need to answer is: How many mL of this solution are required to administer the correct dosage to the child? This is a common scenario in pediatric practice, where medications are often dosed based on a child's weight. The challenge lies in converting units (micrograms to milligrams) and calculating the volume of solution needed to deliver the prescribed dose. To solve this, we will first calculate the total dosage required by the child in micrograms, then convert it to milligrams to match the concentration of our solution. Next, we will use the concentration of the solution to determine the volume needed. This step-by-step approach ensures accuracy and minimizes the risk of errors. It is essential to pay close attention to units throughout the calculation to avoid mistakes. A clear understanding of unit conversions is fundamental to accurate dosage calculation. The information provided in the problem statement is crucial for solving it correctly. We have the child's weight, the required dosage per kilogram, and the concentration of the available solution. Using these pieces of information, we can systematically calculate the required volume of salbutamol solution. This problem highlights the importance of precision in medication administration, especially in pediatric cases. We will now proceed with the calculation, demonstrating each step clearly and concisely.
Step-by-Step Solution: Calculating the Required Salbutamol Volume
Let's break down the solution into manageable steps:
- Calculate the total salbutamol dosage required: The child weighs 15 kg and needs 15 micrograms of salbutamol per kg. So, the total dosage required is 15 kg * 15 micrograms/kg = 225 micrograms.
- Convert micrograms to milligrams: Since the solution concentration is in milligrams, we need to convert the dosage to milligrams. There are 1000 micrograms in 1 milligram. Therefore, 225 micrograms = 225 / 1000 = 0.225 mg.
- Determine the volume of solution required: The solution contains 0.5 mg of salbutamol in 5 ml. This can be expressed as a ratio: 0.5 mg / 5 ml. To find the volume needed for 0.225 mg, we can set up a proportion: (0.5 mg / 5 ml) = (0.225 mg / x ml). Solving for x, we get: x = (0.225 mg * 5 ml) / 0.5 mg = 2.25 ml.
Therefore, 2.25 ml of the salbutamol solution is required to administer the correct dosage to the child. This calculation demonstrates the importance of unit conversion and proportional reasoning in dosage calculations. Each step is crucial to arrive at the correct answer. By following these steps, you can confidently calculate the required volume of medication for various scenarios. This method ensures accurate dosing, promoting patient safety and treatment effectiveness. The use of proportions is a fundamental technique in pharmaceutical calculations. It allows us to relate the concentration of a solution to the desired dosage, enabling precise medication administration. This example showcases a practical application of this technique in pediatric care. We will now discuss the correct answer choice and briefly explain why the other options are incorrect.
Correct Answer and Explanation
Based on our calculations, the correct answer is A. 2.25 mL. This volume of the salbutamol solution will deliver the required 225 micrograms (0.225 mg) of salbutamol to the child. It is crucial to double-check the calculations to ensure accuracy. Now, let's briefly explain why the other options are incorrect:
- B. 4.5 mL: This would deliver twice the required dosage (0.45 mg), which could potentially lead to adverse effects.
- C. 5 mL: This would deliver 0.5 mg of salbutamol, which is more than twice the required dosage and potentially dangerous.
- D. 9.25 mL: This would deliver an even higher dose of salbutamol (0.925 mg), significantly exceeding the prescribed amount and posing a serious risk to the child.
These incorrect options highlight the critical importance of accurate dosage calculation. Administering too much medication can have serious consequences, especially in children. Therefore, always verify your calculations and seek a second opinion if you are unsure. This example underscores the need for precision and attention to detail in medication administration. By understanding the calculations and potential errors, healthcare professionals and caregivers can ensure the safe and effective use of medications. We will now move on to discuss the importance of double-checking calculations and seeking clarification when needed.
The Importance of Double-Checking and Seeking Clarification
In medication dosage calculations, especially in pediatrics, accuracy is paramount. A small error in calculation can lead to a significant overdose or underdose, potentially causing serious harm to the child. Therefore, it is crucial to double-check every step of the calculation to ensure its correctness. One effective method is to repeat the calculation independently, preferably using a different approach if possible. This helps to identify any potential errors in the initial calculation. Another valuable practice is to have another healthcare professional review the calculations. A fresh pair of eyes can often spot mistakes that might have been overlooked. This collaborative approach enhances safety and reduces the risk of errors. In addition to double-checking, it is equally important to seek clarification whenever there is any doubt or ambiguity. If the prescription is unclear or the calculation seems unusual, consult with the prescribing physician or a pharmacist. Never assume or guess when it comes to medication dosages. It is always better to err on the side of caution and seek clarification. This proactive approach is a key component of safe medication practices. Furthermore, it is important to stay updated on the latest guidelines and recommendations for medication dosage calculations. Medical knowledge and practices are constantly evolving, and healthcare professionals have a responsibility to stay informed. By combining careful calculation, double-checking, seeking clarification, and staying updated, we can significantly minimize the risk of medication errors and ensure the safety and well-being of our patients.
