A nurse is reviewing laboratory results for a client who is taking warfarin. Which of the following laboratory tests determines if the dose of medication is within the recommended target range?

Choice A reason: Preventing leakage is not the primary purpose of flushing an intermittent infusion device. Flushing maintains patency by clearing blood or medication residue, preventing clots or blockages. Leakage is addressed by proper capping or clamping, not flushing, making this statement incorrect as it misrepresents the procedure’s purpose.
Choice B reason: Flushing an infusion device does not contribute to hydration, as the flush solution (typically saline) is minimal and not intended for fluid replacement. The purpose is to maintain catheter patency by clearing debris or clots. This statement is incorrect, as it inaccurately suggests a hydration benefit unrelated to the procedure.
Choice C reason: Flushing an intermittent infusion device with saline clears blood or medication residue from the catheter, preventing occlusion and maintaining patency. Blood left in the line can clot, increasing infection risk or blocking the device. This statement accurately reflects the procedure’s purpose, ensuring continued functionality for future medication administration.
Choice D reason: Flushing does not ensure sterility, as the device is already in place and exposed to the bloodstream. Sterility is maintained during insertion or access, not flushing. The primary goal is patency, not sterilization, making this statement incorrect as it misaligns with the procedure’s clinical purpose.

Choice A reason: Reassuring the client about future children minimizes her current grief and loss, which is inappropriate during initial grieving. This dismisses the emotional significance of the stillbirth, potentially causing distress, making it an insensitive and incorrect action.
Choice B reason: Discouraging friends from seeing the newborn restricts the client’s support system and grieving process. Allowing such interactions can provide closure and comfort, so this action is counterproductive and insensitive, making it incorrect for supporting grief.
Choice C reason: Offering to take pictures of the newborn provides a tangible memory, supporting the client’s grieving process. This sensitive intervention validates the loss and aids emotional healing, aligning with best practices for stillbirth care, making it the correct action.
Choice D reason: Advising against discussing the stillbirth isolates the client and hinders grief processing. Open communication with family fosters support and healing, so this action is harmful and contradicts grief support principles, making it incorrect.
