A 6-week-old infant with poor weight gain is scheduled for a pyloromyotomy. Which pre-operative nursing action has the highest priority?

Choice B reason: Elevating the head of the bed to a 45-degree angle is not a sufficient intervention for the nurse to implement before leaving the client. Elevating the head of the bed can help reduce snoring and improve breathing by preventing the tongue and soft palate from falling back and obstructing the airway. However, it may not be enough to prevent apnea episodes in clients with obstructive sleep apnea, especially if they have other risk factors such as obesity, enlarged tonsils, or nasal congestion. The nurse should also use other interventions such as a positive airway pressure device, weight loss, or surgery.

Choice C reason: Removing dentures or other oral appliances is not a relevant intervention for the nurse to implement before leaving the client. Dentures or other oral appliances are devices that replace missing teeth or improve dental alignment. They may help improve speech, chewing, and appearance, but they do not have a direct impact on obstructive sleep apnea. The nurse should instruct the client to remove dentures or other oral appliances before going to bed to prevent discomfort, infection, or damage.

Choice D reason: Lifting and locking the side rails in place is not a necessary intervention for the nurse to implement before leaving the client. Side rails are bars that attach to the sides of the bed frame to prevent falls or injuries. They may provide safety and security for some clients, but they may also pose risks such as entrapment, strangulation, or agitation. The nurse should assess the need for side rails on an individual basis and consider alternative measures such as bed alarms, low beds, or floor mats.

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.
