A nurse is preparing to administer perphenazine 200 mg divided into four equal doses daily to a client who has psychosis. Available is perphenazine oral solution16 mg\/mL. How many mL should the nurse administer per dose? Round the answer to the nearest tenth. (Use a leading zero if it applies. Do not use trailing zeros.)<\/p>\n\n\n\n
The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To determine the amount of perphenazine oral solution to administer per dose, follow these steps:<\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n Perphenazine is administered to manage psychosis, and the correct dosage is crucial for effective treatment while minimizing side effects. The medication is available as a 16 mg\/mL oral solution, which means each milliliter contains 16 mg of perphenazine. To administer 50 mg per dose, you need to determine how much of the solution corresponds to that dosage.<\/p>\n\n\n\n By dividing the desired dose (50 mg) by the concentration of the solution (16 mg\/mL), you calculate the volume of solution needed per dose. This volume, calculated as 3.125 mL, is rounded to the nearest tenth to provide a practical amount to administer, which is 3.1 mL.<\/p>\n\n\n\n Rounding ensures that the medication administration is accurate and manageable in a clinical setting, where precise measurements are essential for patient safety and treatment efficacy.<\/p>\n","protected":false},"excerpt":{"rendered":" A nurse is preparing to administer perphenazine 200 mg divided into four equal doses daily to a client who has psychosis.

The total daily dosage of perphenazine is 200 mg, which is to be divided into four equal doses. [
\\text{Dose per administration} = \\frac{\\text{Total daily dosage}}{\\text{Number of doses per day}} = \\frac{200 \\text{ mg}}{4} = 50 \\text{ mg}
] Therefore, each dose should be 50 mg.<\/li>\n\n\n\n
The available perphenazine oral solution is 16 mg\/mL. To find out how many mL are needed to get 50 mg, use the formula: [
\\text{Volume} = \\frac{\\text{Dose}}{\\text{Concentration}} = \\frac{50 \\text{ mg}}{16 \\text{ mg\/mL}}
] Perform the division: [
\\text{Volume} = 3.125 \\text{ mL}
] Rounding 3.125 to the nearest tenth, we get 3.1 mL.<\/li>\n<\/ol>\n\n\n\n
