A male client reports to the on-call clinic nurse that he took tadalafil 10 mg by mouth two hours ago and his skin now feels flushed. He reports a history of stable angina, but denies experiencing any current or recent chest pain. Which action should the nurse take?

Choice A: Applying an allergy identification wrist band is an intervention that the nurse should implement, as this can alert other health care providers of the client's allergies and prevent adverse reactions. Therefore, this is a correct choice.

Choice B: Instructing the client to avoid medication containing milk and eggs is not an intervention that the nurse should implement, as this is not a common or relevant source of allergens for this client. This is an incorrect choice.

Choice C: Entering allergy information in the client's electronic medical record is an intervention that the nurse should implement, as this can ensure accurate and updated documentation of the client's allergies and facilitate communication among health care providers. Therefore, this is another correct choice.

Choice D: Ensuring the client's selections from her dietary menu is an intervention that the nurse should implement, as this can help avoid foods that may trigger allergic reactions or intolerance for this client. Therefore, this is another correct choice.

Choice E: Notifying the dietary department of the client's egg intolerance is an intervention that the nurse should implement, as this can help modify or substitute foods that contain eggs for this client. Therefore, this is another correct choice.

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.
