A nurse is initiating continuous enteral feedings for a client who has a new gastrostomy tube. Which of the following actions should the nurse take?

A) Encourag’ng the client to consume more fiber is not directly related to the management of hypomagnesemia. While dietary modifications may be necessary for certain conditions, such as constipation, they are not a primary intervention for hypomagnesemia.

B) Limiting sodium-containing foods on the client's meal tray is not a specific intervention for hypomagnesemia. W’ile sodium restriction may be indicated for certain conditions, it does not address the underlying magnesium deficiency.

C) Checking the client's deep tendon reflexes every 4 hours is an appropriate action fo’ a client with hypomagnesemia. Hypomagnesemia can lead to neuromuscular irritability and hyperactive deep tendon reflexes. Monitoring the client's reflexes allows the nurse to assess for changes in neuromuscul’r status and identify potential complications such as tetany.

D) Restricting the client's fluid intake to 500 mL/day is not indicated for hypomagnesemia’ In fact, adequate hydration is important for maintaining electrolyte balance and supporting renal function. Restricting fluid intake could exacerbate dehydration and worsen electrolyte imbalances.

A. A metallic taste is not a clinical hallmark of hyperglycemia. This specific sensory alteration is more commonly associated with certain medications, such as metformin, or as a side effect of diverse pharmacological therapies. It does not correlate with the osmotic or metabolic shifts typically seen with elevated serum glucose levels. While dysgeusia occurs in various conditions, it is not a diagnostic indicator for diabetic crises.

B. Cool, clammy skin is a classic physiological sign of hypoglycemia, rather than hyperglycemia. When blood glucose levels drop, the sympathetic nervous system triggers a "fight or flight" response, leading to diaphoresis and peripheral vasoconstriction. In contrast, hyperglycemic states often present with skin that is warm, dry, and flushed due to dehydration and vasodilation. Understanding this dermatological difference is crucial for the nurse to distinguish between the two glycemic extremes.

C. Hyperventilation, specifically Kussmaul respirations, is a significant manifestation of severe hyperglycemia and impending diabetic ketoacidosis. As the body attempts to compensate for metabolic acidosis caused by ketone accumulation, the respiratory center increases the rate and depth of breaths to expel carbon dioxide. This deep, rapid breathing pattern is a critical scientific sign that the client's metabolic state is deteriorating. Identifying this early allows for rapid clinical intervention to restore acid-base balance.

D. Anxiety is a neuroglycopenic symptom predominantly associated with hypoglycemia. As the brain is deprived of its primary energy source, glucose, the resulting adrenal stress response manifests as nervousness, tremors, and tachycardia. While a client with hyperglycemia may feel unwell, they do not typically exhibit the acute adrenergic surge characterized by anxiety. The nurse should educate the client that these emotional fluctuations are more indicative of low blood sugar levels.
