A nurse is planning to teach a group of newly licensed nurses about hypermagnesemia. Which of the following manifestations should the nurse include in the teaching?

Rationale for indicated actions:

• Titrate the rate of infusion to maintain the client's blood pressure at least 90/60 mm Hg: The nurse should follow the ordered transfusion rate and not titrate it based on blood pressure. The priority is to transfuse the blood safely and at the prescribed rate, while monitoring the client's response. Blood pressure will improve as the blood volume is restored.
• Obtain the first unit of packed RBCs from the blood bank: This is necessary to correct the client’s anemia (Hgb 9.1 g/dL, Hct 27%) and address the suspected acute blood loss indicated by positive hemoccult stool and hemodynamic changes.
• Document the blood product transfusion in the client's medical record: Accurate documentation ensures legal compliance, tracks the administration, and records the client’s response, including any adverse events, supporting continuity of care.
• Stay with the client for the first 15 min of the transfusion: Most transfusion reactions occur during the first 15 minutes. Close observation allows for immediate intervention if the client develops fever, hypotension, or other adverse effects.

• Start an IV bolus of lactated Ringer's solution: Lactated Ringer’s contains calcium which can cause clotting in the transfusion line. Using LR can lead to hemolysis or transfusion complications. Only 0.9% sodium chloride should be used for flushing or running alongside blood transfusions.

A. Activity level: Restlessness, pacing, and inability to remain seated are early neurological manifestations of water intoxication, stemming from cerebral edema related to hyponatremia. These signs often precede more severe symptoms like seizures.

B. White blood cell count: A count of 9,100/mm³ is within normal limits and does not indicate water intoxication. This value is unrelated to the dilutional effects of excessive fluid intake.

C. Sodium level: A sodium of 130 mEq/L indicates hyponatremia, which is a hallmark laboratory finding in water intoxication due to dilutional effects from excess fluid intake. Low sodium can cause neurological changes and altered mental status.

D. Potassium level: A potassium of 3.6 mEq/L is within the normal range and does not support a diagnosis of water intoxication. Potassium is less affected by acute overhydration compared to sodium.

E. Hallucinations: Responding to unseen stimuli can occur when hyponatremia causes cerebral swelling, disrupting normal brain function. In clients with psychotic disorders, excess water intake can exacerbate hallucinations or make them more pronounced.
