A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?

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 rise. 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.

Based on the collected data, the nurse recognizes that the client is most likely exhibiting signs of Stroke as evidenced by Neurological defects and Garbled speech. The symptoms of facial drooping, garbled speech, and high blood pressure are common signs of a stroke. However, it’s important to get a professional medical diagnosis as soon as possible. Please seek immediate medical attention.

Choice A rationale:

Intoxication is a plausible explanation for the client’s symptoms, especially given the report of alcohol consumption. However, intoxication typically does not cause facial drooping, which is a common sign of neurological issues such as a stroke. Therefore, while intoxication may contribute to the client’s condition, it is not the most likely primary cause.

Choice B rationale:

Stroke is a medical emergency that often presents with facial drooping and garbled speech, both of which are observed in this client. A stroke occurs when blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. This can lead to brain cells dying in minutes. The client’s high blood pressure (210/98 mm Hg) is a significant risk factor for stroke. Normal blood pressure ranges from 90/60 mm Hg to 120/80 mm Hg.

Choice C rationale:

An allergic reaction could cause various symptoms, but it typically does not result in facial drooping or garbled speech. Common signs of an allergic reaction include hives, itching, redness, and swelling of the skin, as well as difficulty breathing in severe cases (anaphylaxis). There is no mention of these symptoms in the client’s presentation.

Choice D rationale:

Malignant hypertension is a possibility given the client’s extremely high blood pressure reading. This condition refers to severe hypertension that can quickly lead to organ damage. However, while it can cause neurological symptoms if it leads to a hypertensive crisis, the specific symptoms of facial drooping and garbled speech are more indicative of a stroke. In conclusion, based on the collected data, the nurse recognizes that the client is most likely exhibiting signs of a stroke as evidenced by neurological defects (facial drooping and garbled speech). The client’s high blood pressure and reported alcohol consumption are both risk factors for stroke. Immediate medical intervention is crucial to minimize brain damage and potential complications.
