The client who has been taking glipizide for 6 months reports to the nurse that his urine has become darker since starting the medication. What is the nurse's first action?

A. Lethargy can occur in DKA due to the effects of hyperglycemia, acidosis, and dehydration. Even if the client is oriented, confusion about the reason for care suggests an altered mental state, which can be common in DKA.
B. This ABG indicates alkalosis (pH > 7.45), which is not typical for DKA. In DKA, we would expect a lower pH (acidosis). This set of values does not align with the expected clinical picture of DKA.
C. This ABG shows a pH of 7.31, indicating acidosis. The low HCO3 (17) supports metabolic acidosis, which is characteristic of DKA. This finding is consistent with the expected laboratory results in a patient experiencing DKA.
D. A heart rate of 52 (bradycardia) is not a common finding in DKA. In fact, tachycardia (elevated heart rate) is typically observed due to dehydration and compensatory mechanisms. Bradycardia would not be expected in this context.
E. A respiratory rate of 31, particularly if deep (known as Kussmaul respirations), is a classic sign of metabolic acidosis, including DKA. Kussmaul respirations are the body’s attempt to compensate for acidosis by increasing carbon dioxide elimination.

A. The nurse should notify the prescriber about the current dose (7 mL/hr) because the patient is ordered 1600 units of heparin per hour. The current infusion rate needs to be assessed in relation to the aPTT result, especially if the aPTT indicates that the patient may be at risk for bleeding.
B. While having a second IV may be useful for administering fluids or medications in case of a bleeding emergency, there is no immediate indication for IV 0.9 saline in this scenario. The priority is to assess the heparin dosage and aPTT before making additional IV arrangements.
C. It’s important to assess the IV site for signs of infiltration, especially since the patient is on heparin therapy. Infiltration can affect the effectiveness of the medication and cause complications, so this assessment is vital.
D. While it is important to verify lab results, the nurse should primarily focus on addressing the current situation regarding the heparin infusion and the patient’s anticoagulation status rather than confirming lab results with the lab technician at this moment.
E. While protamine sulfate is an antidote to heparin, it is not warranted based solely on the aPTT result of 37 seconds. The normal aPTT range is typically around 30-40 seconds, depending on the laboratory standards, and the aPTT may not indicate that the patient requires reversal of heparin at this time.
