A client who has atrial fibrillation is prescribed warfarin therapy.

Which of the following statements by the client indicates an understanding of the medication?

Choice B rationale:

Stroke is a condition that occurs when the blood supply to a part of the brain is interrupted, causing brain tissue damage. Facial drooping and garbled speech are common signs of stroke, especially if they occur suddenly and on one side of the face.Stroke is a medical emergency that requires immediate treatment to prevent further brain damage and complications

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.

Choice A rationale:

A pH level of 7.35 to 7.45 and HCO3- level of 22 to 26 mEq/L indicate a resolution of ketoacidosis. The normal pH range for the body is 7.35 to 7.45, and a return to this range indicates that the body’s acid-base balance has been restored. The bicarbonate (HCO3-) level is a measure of the metabolic component of the body’s acid-base balance, and the normal range is 22 to 26 mEq/L. A return to this range indicates that the metabolic acidosis caused by the ketoacidosis has been resolved.

Choice B rationale:

A pH level of 7.25 to 7.35 and HCO3- level of 18 to 22 mEq/L would indicate that the client is still in a state of mild acidosis, as the pH is below the normal range and the bicarbonate level is also slightly low, indicating a metabolic acidosis.

Choice C rationale:

A pH level of 7.15 to 7.25 and HCO3- level of 14 to 18 mEq/L would indicate a moderate acidosis. Both the pH and bicarbonate levels are significantly below their normal ranges, indicating a significant disruption in the body’s acid-base balance.

Choice D rationale:

A pH level of 7.05 to 7.15 and HCO3- level of 10 to 14 mEq/L would indicate severe acidosis, which would be life-threatening if not corrected. Both the pH and bicarbonate levels are far below their normal ranges, indicating a severe disruption in the body’s acid-base balance. In conclusion, choice A is correct because it represents values within the normal ranges for both pH and bicarbonate, indicating a resolution of ketoacidosis.
