A nurse is preparing a client with Crohn’s disease for a barium enema. What should the nurse do the day before the test?

Choice A Reason:

Metabolic alkalosis is characterized by an elevated pH (greater than 7.45) and an increased bicarbonate (HCO3) level. In this case, the pH is 7.30, indicating acidosis, and the HCO3 level is 18 mEq/L, which is below the normal range (22-26 mEq/L). Therefore, metabolic alkalosis is not the correct diagnosis.

Choice B Reason:

Respiratory alkalosis is indicated by a high pH (greater than 7.45) and a low PaCO2 (less than 35 mm Hg). Although the PaCO2 is low at 28 mm Hg, the pH is 7.30, indicating acidosis rather than alkalosis. Therefore, respiratory alkalosis is not the correct diagnosis.

Choice C Reason:

Respiratory acidosis is characterized by a low pH (less than 7.35) and an elevated PaCO2 (greater than 45 mm Hg). In this case, the pH is low, indicating acidosis, but the PaCO2 is also low at 28 mm Hg, which does not fit the criteria for respiratory acidosis. Therefore, respiratory acidosis is not the correct diagnosis.

Choice D Reason:

Metabolic acidosis is indicated by a low pH (less than 7.35) and a low bicarbonate (HCO3) level (less than 22 mEq/L). In this case, the pH is 7.30, indicating acidosis, and the HCO3 level is 18 mEq/L, which is below the normal range. The low PaCO2 of 28 mm Hg suggests a compensatory respiratory response to the metabolic acidosis. Therefore, metabolic acidosis is the correct diagnosis.

Choice A reason:

Elevating the head of the client’s bed can help reduce blood pressure slightly by promoting venous return and decreasing intracranial pressure. However, this action alone is not sufficient to address the severe hypertension (254/139 mm Hg) the client is experiencing. Immediate medical intervention is required to prevent complications such as stroke, heart attack, or organ damage.

Choice B reason:

Contacting the Rapid Response Team is the highest priority action. The Rapid Response Team is trained to handle critical situations and can provide immediate interventions to stabilize the client’s condition. Severe hypertension at this level requires urgent medical attention to prevent life-threatening complications. The team can administer medications to lower blood pressure quickly and monitor the client closely.

Choice C reason:

Telling the client to report vision changes is important because vision changes can indicate hypertensive retinopathy or increased intracranial pressure. However, this action is not the immediate priority. The client’s blood pressure needs to be controlled urgently to prevent further complications.

Choice D reason:

Inserting a peripheral IV is necessary for administering medications and fluids. While this is an important step, it should follow the immediate action of contacting the Rapid Response Team. The team can then use the IV access to administer antihypertensive medications promptly.

Choice E reason:

Initiating seizure precautions is important because severe hypertension can lead to seizures. However, this action is not the first priority. The primary focus should be on stabilizing the client’s blood pressure through immediate medical intervention.
