A patient is receiving Gabapentin (Neurontin), an anticonvulsant, but has no history of seizures. The nurse expects that the patient is receiving this drug for which condition?

Acute adrenal insufficiency, also known as adrenal crisis, is characterized by low levels of adrenal hormones, particularly cortisol. One of the primary manifestations of adrenal insufficiency is electrolyte imbalance, specifically hyponatremia (low sodium) and hyperkalemia (high potassium). Inadequate cortisol levels can lead to impaired sodium reabsorption in the kidneys, resulting in sodium loss and low serum sodium levels.

When the patient receives appropriate therapies for acute adrenal insufficiency, such as administration of glucocorticoids (e.g., hydrocortisone), the cortisol levels begin to normalize. As a result, the impaired sodium reabsorption improves, leading to an increase in serum sodium levels.

Pernicious anemia is a type of anemia that occurs due to a lack of intrinsic factor, a protein necessary for the absorption of vitamin B12 (cobalamin) in the digestive system. As a result, patients with pernicious anemia are unable to absorb sufficient amounts of vitamin B12 from dietary sources. The treatment for pernicious anemia involves regular administration of cobalamin (B12) injections to bypass the impaired absorption and provide the necessary vitamin B12 directly.

Oral ferrous sulfate tablets are not the appropriate treatment for pernicious anemia. Ferrous sulfate is a form of iron supplement used to treat iron deficiency anemia, which is different from pernicious anemia.

Iron dextran infusions are also not indicated for pernicious anemia. Iron dextran is used for iron replacement therapy in cases of iron deficiency anemia, but it does not address the underlying issue of vitamin B12 deficiency in pernicious anemia.

Routine blood transfusions may be necessary in some cases of pernicious anemia, especially if the patient is severely anemic. However, the primary treatment for pernicious anemia is cobalamin (B12) injections, which provide the necessary vitamin B12 that the patient is unable to absorb.
