A nurse is preparing to administer lorazepam 50 mcg\/kg IM to a client who weighs 176 lb. Available is lorazepam 4 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:<\/mark><\/strong><\/p>\n\n\n\n To calculate the amount of lorazepam to administer, we need to follow these steps:<\/p>\n\n\n\n The nurse should administer 1 mL<\/strong> of lorazepam. This calculation ensures that the patient receives the correct dosage based on their weight and the available medication concentration. Administering the precise dose is crucial in preventing both under-treatment and potential overdose, particularly with medications like lorazepam, which is used for anxiety and sedation. Always confirm calculations and dosages, especially with medications that have a narrow therapeutic range.<\/p>\n","protected":false},"excerpt":{"rendered":" A nurse is preparing to administer lorazepam 50 mcg\/kg IM to a client who weighs 176 lb.

The client weighs 176 lb. To convert pounds to kilograms, we use the conversion factor:1\u00a0lb=0.453592\u00a0kg1 \\text{ lb} = 0.453592 \\text{ kg}1\u00a0lb=0.453592\u00a0kgThus,176\u00a0lb\u00d70.453592\u00a0kg\/lb\u224879.832\u00a0kg176 \\text{ lb} \\times 0.453592 \\text{ kg\/lb} \\approx 79.832 \\text{ kg}176\u00a0lb\u00d70.453592\u00a0kg\/lb\u224879.832\u00a0kgFor practical purposes, we can round this to 79.8 kg.<\/li>\n\n\n\n
The prescribed dose is 50 mcg\/kg. Therefore, the total dosage for the client is:50\u00a0mcg\/kg\u00d779.8\u00a0kg=3990\u00a0mcg50 \\text{ mcg\/kg} \\times 79.8 \\text{ kg} = 3990 \\text{ mcg}50\u00a0mcg\/kg\u00d779.8\u00a0kg=3990\u00a0mcg<\/li>\n\n\n\n
Since 1 mg = 1000 mcg, we convert:3990\u00a0mcg\u00f71000=3.99\u00a0mg3990 \\text{ mcg} \\div 1000 = 3.99 \\text{ mg}3990\u00a0mcg\u00f71000=3.99\u00a0mg<\/li>\n\n\n\n
The available concentration of lorazepam is 4 mg\/mL. To find the volume in mL to administer, we use the formula:Volume\u00a0(mL)=Dosage\u00a0(mg)Concentration\u00a0(mg\/mL)\\text{Volume (mL)} = \\frac{\\text{Dosage (mg)}}{\\text{Concentration (mg\/mL)}}Volume\u00a0(mL)=Concentration\u00a0(mg\/mL)Dosage\u00a0(mg)\u200bSubstituting the values:Volume\u00a0(mL)=3.99\u00a0mg4\u00a0mg\/mL\u22480.9975\u00a0mL\\text{Volume (mL)} = \\frac{3.99 \\text{ mg}}{4 \\text{ mg\/mL}} \\approx 0.9975 \\text{ mL}Volume\u00a0(mL)=4\u00a0mg\/mL3.99\u00a0mg\u200b\u22480.9975\u00a0mL<\/li>\n\n\n\n
Rounding 0.9975 mL gives us 1 mL.<\/li>\n<\/ol>\n\n\n\nConclusion<\/h3>\n\n\n\n
