A nurse is teaching a client with diabetes mellitus who asks, "Why is it necessary to maintain my blood glucose levels no lower than about 60 mg/dL?" How should the nurse respond?

Choice A rationale: The described symptoms—diaphoresis, palpitations, nervousness, and tachycardia—are classic signs of hypoglycemia, or low blood glucose. These symptoms are caused by the release of counter-regulatory hormones like epinephrine and cortisol. The first appropriate action is to check the blood glucose level to confirm hypoglycemia and then administer carbohydrates to rapidly raise it back to a safe range.
Choice B rationale: Giving nitroglycerin and performing an electrocardiogram are interventions for cardiac issues, such as angina or myocardial infarction. While palpitations and tachycardia are present, they are secondary to the hypoglycemia-induced stress response, not a primary cardiac event. Addressing the underlying hypoglycemia is the priority, as these cardiac symptoms are a direct physiological consequence of the low blood sugar.
Choice C rationale: Checking pulse oximetry and administering oxygen are interventions for respiratory compromise or hypoxemia. The client's symptoms are not indicative of an issue with oxygenation. Although the body is under stress, the primary problem is a metabolic imbalance, specifically low blood glucose. Providing oxygen would not correct the underlying physiological cause of the symptoms.
Choice D rationale: Restricting salt, administering diuretics, and performing paracentesis are treatments for fluid overload, ascites, and conditions like congestive heart failure or severe liver disease. The client's symptoms are not consistent with these conditions. These interventions would be inappropriate and could be harmful, as they do not address the metabolic derangement causing the hypoglycemia.

Choice A rationale: Oxygen delivery equipment is essential post-thyroidectomy due to the risk of respiratory distress. Surgical manipulation near the trachea can cause swelling, compromising the airway. Additionally, laryngeal nerve damage is a potential complication, which can lead to vocal cord paralysis and airway obstruction. Having oxygen readily available ensures immediate intervention for hypoxemia.
Choice B rationale: Humidified air is not a primary, immediately essential piece of emergency equipment for a client from the PACU post-thyroidectomy. While it can be used to soothe an irritated airway and reduce coughing, it is not a life-saving intervention for acute respiratory distress. The most critical concerns are airway obstruction and bleeding.
Choice C rationale: Suction equipment is vital to manage potential airway obstruction from secretions or blood. Post-thyroidectomy, there is a risk of hemorrhage and edema, which can lead to pooling of blood or fluid in the pharyngeal area. A functional suction setup allows for the immediate clearance of the airway to maintain patency.
Choice D rationale: A tracheostomy tray is crucial emergency equipment because of the high risk of airway compromise. Postoperative edema, hematoma formation, or laryngeal nerve damage can cause acute respiratory distress. If intubation is not possible, an emergency tracheostomy may be required to secure the airway and prevent suffocation.
Choice E rationale: A padded tongue blade is not a recommended piece of equipment for a client post-thyroidectomy. The use of a tongue blade is associated with a risk of damaging the oral tissues and is ineffective for managing the specific airway complications, such as edema or hematoma, that are most likely to occur after this surgery.
