The client with Clostridium difficile in the stool receives a prescription for vancomycin PO. Which action should the nurse take before administering the first dose?

Drinking plenty of water whenever thirsty is not the most appropriate action for a patient with hypernatremia. While it's important to stay hydrated, excessive water intake can potentially worsen hypernatremia by diluting blood sodium levels further. This is because the body tries to balance sodium levels by either retaining water or excreting it through urine. In hypernatremia, the body is already short on water relative to sodium, so consuming too much water can exacerbate the imbalance.

Choice B rationale:

Reviewing food labels for sodium content is crucial for managing hypernatremia. It empowers patients to make informed choices and limit their sodium intake.

Sodium is a major contributor to hypernatremia, and reducing dietary sodium intake is a key strategy to lower blood sodium levels.

By carefully reading food labels and selecting low-sodium options, patients can effectively manage their sodium intake and promote a gradual return to normal sodium levels.

This approach addresses the root cause of hypernatremia and promotes long-term control of blood sodium levels.

Choice C rationale:

Monitoring daily urine output volume can be helpful in tracking fluid status, but it's not the primary action for managing hypernatremia.

While urine output can provide insights into fluid balance, it doesn't directly address the underlying issue of excessive sodium. Focusing on dietary sodium intake is a more direct and effective approach to correcting hypernatremia.

Choice D rationale:

Using salt tablets after strenuous exercise is not recommended for patients with hypernatremia.

Salt tablets are intended to replenish electrolytes lost through sweating, but they can worsen hypernatremia by further increasing sodium levels.

Patients with hypernatremia should focus on reducing sodium intake, not increasing it.

Choice A rationale:

Hemoglobin A1C (HbA1C) is a blood test that reflects a person's average blood glucose levels over the past 2-3 months. It's considered the gold standard for diagnosing and monitoring diabetes.

An HbA1C level of 8.29% is significantly elevated above the reference range of 4-5.99%, indicating a high probability of diabetes.

The patient's HbA1C has also increased from 7.59% three months ago, suggesting a worsening of glycemic control.

Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels due to impaired insulin production or action, or both.

Common symptoms of diabetes include increased thirst, frequent urination, fatigue, blurred vision, and slow-healing wounds.

Early diagnosis and treatment of diabetes are crucial to prevent complications such as heart disease, stroke, kidney disease, nerve damage, and vision loss.

Choice B rationale:

Hypoglycemia refers to abnormally low blood glucose levels, typically below 70 mg/dL. It's often caused by excessive insulin or medication, missed meals, or strenuous exercise.

The patient's HbA1C level of 8.29% does not support a diagnosis of hypoglycemia.

Choice C rationale:

Hyperglycemia refers to abnormally high blood glucose levels, typically above 180 mg/dL. It can be caused by diabetes, stress, infection, or certain medications.

While the patient's HbA1C level does indicate hyperglycemia, it's specifically the pattern of elevated HbA1C over time that points to a diagnosis of diabetes mellitus, rather than transient hyperglycemia.

Choice D rationale:

Prediabetes is a condition where blood glucose levels are higher than normal, but not high enough to be classified as diabetes. People with prediabetes are at increased risk of developing diabetes.

The patient's HbA1C level of 8.29% is above the threshold for prediabetes, which is typically 5.7-6.4%.
