A nurse is preparing to administer vitamin K 1 mg IM to a newborn. Available is vitamin K injection 1 mg\/0.5 mL. How many mL should the nurse administer per dose?<\/p>\n\n\n\n

A.
Choice A: 0.25 mL<\/p>\n\n\n\n

B.
Choice B: 0.5 mL<\/p>\n\n\n\n

C.
Choice C: 0.75 mL<\/p>\n\n\n\n

D.
Choice D: 1 mL<\/p>\n\n\n\n

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

The correct answer is B. 0.5 mL<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the correct amount to administer, the nurse needs to calculate the dose based on the available concentration of the medication. Here’s the breakdown of how to approach this:<\/p>\n\n\n\n

    \n
  1. Ordered dose:<\/strong> The provider has prescribed 1 mg<\/strong> of vitamin K to be given to the newborn.<\/li>\n\n\n\n
  2. Available concentration:<\/strong> The medication available is vitamin K injection at a concentration of 1 mg\/0.5 mL<\/strong>, meaning that each 0.5 mL of the solution contains 1 mg of vitamin K.<\/li>\n\n\n\n
  3. Dosage calculation:<\/strong>
    The formula to calculate how much to administer is: [
    \\text{Dose to administer (mL)} = \\left(\\frac{\\text{Prescribed dose (mg)}}{\\text{Available concentration (mg\/mL)}}\\right)
    ] Plugging in the values: [
    \\text{Dose to administer} = \\left(\\frac{1 \\text{ mg}}{1 \\text{ mg\/0.5 mL}}\\right) = 0.5 \\text{ mL}
    ]<\/li>\n<\/ol>\n\n\n\n

    This means the nurse should administer 0.5 mL<\/strong> to deliver the ordered dose of 1 mg of vitamin K.<\/p>\n\n\n\n

    Rationale for Using Vitamin K in Newborns:<\/h3>\n\n\n\n

    Vitamin K is routinely administered to newborns shortly after birth to prevent Vitamin K Deficiency Bleeding (VKDB), previously known as hemorrhagic disease of the newborn. Newborns are naturally deficient in vitamin K due to limited placental transfer, a sterile gut (hence no gut flora to synthesize vitamin K), and low vitamin K content in breast milk. This deficiency can lead to serious bleeding issues if not corrected.<\/p>\n\n\n\n

    By administering vitamin K intramuscularly, the newborn’s risk of bleeding complications, particularly brain hemorrhages and gastrointestinal bleeds, is significantly reduced.<\/p>\n\n\n\n

    Conclusion:<\/h3>\n\n\n\n

    By following the dosage calculation formula, the nurse will administer 0.5 mL<\/strong> of vitamin K to ensure the newborn receives the full prescribed dose of 1 mg.<\/p>\n","protected":false},"excerpt":{"rendered":"
