A client who is hypotensive is receiving dopamine, an adrenergic agonist, IV at the rate of 8 mcg/kg/min. Which intervention should the nurse implement while administering this medication?

Choice C is correct because vitamin K can interfere with the anticoagulant effect of warfarin and increase the risk of clotting. The client should maintain a consistent intake of vitamin K from food sources, such as dark green leafy vegetables, to avoid fluctuations in the blood levels of warfarin.

Choice A is incorrect because increasing the intake of dark green leafy vegetables while taking warfarin can decrease the effectiveness of warfarin and increase the risk of clotting.

Choice B is incorrect because eating two servings of dark green leafy vegetables daily and continuing for 30 days after warfarin therapy is completed can cause unpredictable changes in the blood levels of warfarin and increase the risk of bleeding or clotting.

Choice D is incorrect because avoiding any foods that contain any vitamin K while taking warfarin can increase the sensitivity to warfarin and increase the risk of bleeding.

Choice C is correct because pushing the undiluted Dextrose slowly through the currently infusing IV is the best way to administer the medication for a client with insulin shock. Insulin shock is a condition in which the blood glucose level drops too low due to excess insulin or insufficient food intake. This can cause symptoms such as confusion, sweating, tremors, or loss of consciousness. The nurse should administer 50% Dextrose IV as a bolus injection to raise the blood glucose level quickly and prevent brain damage.

Choice A is incorrect because asking the pharmacist to add the Dextrose to a TPN solution is not appropriate for a client with insulin shock. TPN stands for total parenteral nutrition, which is a type of intravenous feeding that provides all the nutrients needed by the body. TPN solutions contain dextrose, amino acids, lipids, vitamins, minerals, and electrolytes in specific concentrations and ratios. Adding extra dextrose to a TPN solution can alter its composition and cause complications such as hyperglycemia or fluid overload.

Choice B is incorrect because mixing the Dextrose in a 50 mL piggyback for a total volume of 100 mL is not effective for a client with insulin shock. A piggyback is a type of intravenous infusion that delivers medication through a secondary tubing attached to the primary tubing of another solution. Mixing the Dextrose in a piggyback can dilute its concentration and reduce its potency. It can also delay its delivery and onset of action.

Choice D is incorrect because diluting the Dextrose in one liter of 0.9% Normal Saline solution is not safe for a client with insulin shock. Normal Saline is a type of intravenous fluid that contains sodium chloride in isotonic concentration. Diluting the Dextrose in one liter of Normal Saline can lower its concentration and increase its volume significantly. This can cause complications such as hypoglycemia or fluid overload.
