A nurse is preparing a client for discharge who was admitted for diabetic ketoacidosis. Which of the following statements should the nurse include in the discharge teaching?

Choice A rationale:

Severe headache can be a symptom of a subdural hematoma, but it is not the earliest manifestation of a change in neurological status. Other symptoms may appear before a severe headache, such as an altered level of consciousness.

Choice B rationale:

Bradycardia can occur with a subdural hematoma, especially as intracranial pressure increases. However, it is not the earliest manifestation of a change in neurological status. Changes in heart rate may occur later in the progression of the condition.

Choice C rationale:

Widened pulse pressure can also occur in patients with a subdural hematoma due to increased intracranial pressure. However, it is not the earliest manifestation of a change in neurological status. Other neurological signs would likely appear before changes in pulse pressure are evident.

Choice D rationale:

Change in level of consciousness is the earliest manifestation of a change in neurological status with a subdural hematoma. As intracranial pressure increases, the brain's functioning can be affected, leading to alterations in consciousness, ranging from mild confusion to unconsciousness.

Choice A rationale:
The combination of widened QRS, frequent premature ventricular contractions (PVCs), and bradycardia (heart rate of 55/min) on telemetry monitoring suggests hyperkalemia. Elevated potassium levels in the blood can cause delayed repolarization of cardiac cells, leading to widened QRS complexes and PVCs. Bradycardia is another common manifestation of hyperkalemia.
Choice B rationale:
Hypocalcemia, characterized by low calcium levels in the blood, can lead to cardiac arrhythmias, but it typically presents with a prolonged QT interval rather than widened QRS complexes and PVCs.
Choice C rationale:
Hyperglycemia, which is high blood glucose levels, does not directly affect the electrocardiogram (ECG) parameters like QRS width or heart rate. It may have systemic effects, but it is not responsible for the ECG changes described in the scenario.
Choice D rationale:
Hypophosphatemia, or low levels of phosphate in the blood, can cause muscle weakness and may have systemic effects, but it is not associated with the specific ECG changes seen in hyperkalemia, such as widened QRS complexes and PVCs.
