A nurse is preparing to administer ondansetron 4 mg IM stat. The amount available is ondansetron for injection 2 mg\/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)<\/p>\n\n\n\n

The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To determine how many mL of ondansetron to administer, you can use the formula:<\/p>\n\n\n\n

[
\\text{Volume (mL)} = \\frac{\\text{Desired Dose (mg)}}{\\text{Available Concentration (mg\/mL)}}
]<\/p>\n\n\n\n

In this case, the desired dose of ondansetron is 4 mg, and the available concentration is 2 mg\/mL.<\/p>\n\n\n\n

Substituting the values into the formula:<\/p>\n\n\n\n

[
\\text{Volume (mL)} = \\frac{4 \\text{ mg}}{2 \\text{ mg\/mL}} = 2 \\text{ mL}
]<\/p>\n\n\n\n

So, the nurse should administer 2 mL<\/strong> of ondansetron.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n
    \n
  1. Understanding the Dosage Calculation<\/strong>: This calculation is essential in nursing and pharmacology to ensure patients receive the correct medication dose. Accurate dosing is crucial for efficacy and safety.<\/li>\n\n\n\n
  2. Desired Dose vs. Available Concentration<\/strong>: The “desired dose” refers to the amount prescribed by a physician or required for treatment. The “available concentration” indicates how much of the drug is present in each mL of the solution. Understanding these terms helps in performing accurate calculations.<\/li>\n\n\n\n
  3. Performing the Calculation<\/strong>: By dividing the desired dose by the available concentration, you convert the required medication amount into a volume (in mL). Here, you calculated how many mL of a solution are needed to achieve the therapeutic effect intended with 4 mg of ondansetron.<\/li>\n\n\n\n
  4. Rounding Rules<\/strong>: The instructions specify rounding to the nearest whole number and using a leading zero if needed. In this case, the answer (2 mL) already meets this requirement.<\/li>\n\n\n\n
  5. Importance of Accuracy<\/strong>: In a clinical setting, administering the wrong dose can lead to under-treatment or potential overdose, so mastering these calculations is vital for patient safety.<\/li>\n<\/ol>\n\n\n\n

    This precise calculation ensures that the patient receives the appropriate medication dose quickly, particularly in urgent situations, such as those requiring an immediate intervention for nausea or vomiting.<\/p>\n","protected":false},"excerpt":{"rendered":"
