An adult client is admitted to the critical care unit with systemic inflammatory response syndrome (SIRS) as a result of a postburn infection. The client has a long line peripherally inserted IV catheter for fluid and medication administration and current vital signs include temperature 102.8°F (39.3°C., heart rate 108 beats/minute, respirations 32 breaths/minute. Which action should the nurse implement first?

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.

Choice B is correct because anxiety is the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Anxiety is a feeling of fear, nervousness, or apprehension that can interfere with coping and decision making. The nurse should assess the level and source of anxiety and provide emotional support and reassurance to the client. The nurse should also review the pain management techniques and explain the benefits and risks of different analgesic options.

Choice A is incorrect because knowledge deficit is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Knowledge deficit is a lack of information or understanding about a topic or situation that can affect learning and behavior. The nurse should evaluate the client's learning needs and provide appropriate education and resources, but this is not as urgent as addressing the client's anxiety.

Choice C is incorrect because pain intolerance is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Pain intolerance is an inability or unwillingness to endure pain that can affect quality of life and recovery. The nurse should assess the client's pain level and response to analgesics and adjust the pain management plan accordingly, but this is not as urgent as addressing the client's anxiety.

Choice D is incorrect because anticipatory grieving is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Anticipatory grieving is a process of mourning that occurs before an expected loss or death that can affect emotional and physical well-being. The nurse should acknowledge the client's feelings and provide empathy and support, but this is not as urgent as addressing the client's anxiety.
