The healthcare provider prescribes the antibiotic cefdinir 300 mg by mouth every 12 hours for a client with a postoperative wound infection.
Which foods should the nurse encourage this client to eat?

Choice A rationale:

Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise1. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.

Choice B rationale:

Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.

Choice C rationale:

Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.

Choice D rationale:

Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.

Choice E rationale:

Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.

Choice F rationale:

Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.

The correct answer is choice B.

Choice A rationale: Metabolic alkalosis is caused by a loss of acid or a gain of base. It is not typically associated with anxiety or hyperventilation.

Choice B rationale: Respiratory alkalosis is caused by hyperventilation, which leads to a decrease in carbon dioxide levels in the blood. This can occur in response to anxiety, pain, or other stressors.

Choice C rationale: Metabolic acidosis is caused by a buildup of acid in the blood or a loss of bicarbonate. It is not typically associated with anxiety or hyperventilation.

Choice D rationale: Respiratory acidosis is caused by hypoventilation, which leads to an increase in carbon dioxide levels in the blood. It is not typically associated with anxiety or hyperventilation.
