The nurse is planning discharge instructions for a client with type 2 diabetes who will be starting exenatide.

Which information should be included in the discharge instructions?

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 D.

Choice A rationale: Moving Client D into an isolation room 24 hours before surgery is not necessary. The client’s white blood cell (WBC) count is 14,000 mm (14 x 10^9/L), which is higher than the normal range of 5000 to 10,000/mm² (5 to 10 x 10^9/L). This indicates that the client may have an infection. However, it is not standard practice to isolate clients scheduled for surgery based solely on an elevated WBC count. Other factors, such as the presence of specific infectious diseases, would dictate the need for isolation.

Choice B rationale: Asking the dietitian to add a banana to Client C’s breakfast tray is not necessary. The client’s potassium level is 3.8 mEq/L (3.8 mmol/L), which is within the normal range of 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Therefore, there is no need to increase the client’s potassium intake.

Choice C rationale: Increasing Client A’s oxygen to 4 liters a minute per cannula is not necessary. The client has emphysema and their oxygen saturation is 94%, which is within the normal range. Increasing the oxygen flow rate could lead to oxygen toxicity or suppress the client’s respiratory drive, leading to respiratory depression or failure.

Choice D rationale: Verifying that Client B has two units of packed cells available is the correct intervention. The client’s postoperative hemoglobin level is 8.2 mg/dL (82 g/L), which is lower than the normal range of 14 to 18 g/dL (140 to 180 g/L). This indicates that the client is anemic and may require a blood transfusion. Therefore, it is important to ensure that packed cells are available if needed.
