A nurse in an emergency department (ED) is caring for a client

Exhibits

Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

A. Hyponatremia: While hyponatremia can cause neurological symptoms, such as confusion and seizures, it is not typically associated with a positive Trousseau's sign. Trousseau's sign is more specifically related to calcium imbalances.
B. Hypocalcemia: A positive Trousseau's sign (a spasm of the hand and wrist when a blood pressure cuff is inflated) is a classic sign of hypocalcemia, which is low calcium levels in the blood. Numbness and tingling of the toes (paresthesia) are also common symptoms of hypocalcemia.
C. Hyperkalemia: Hyperkalemia typically causes muscle weakness, fatigue, and potential cardiac arrhythmias, but it does not directly cause a positive Trousseau's sign or numbness and tingling in the extremities.
D. Hypermagnesemia: Hypermagnesemia (high magnesium levels) typically causes symptoms such as muscle weakness, respiratory depression, and hypotension. It is not associated with a positive Trousseau's sign.

Rationale for correct choices:

• Hyperthyroidism: The client presents with classic signs of hyperthyroidism or thyroid storm: heat intolerance, tremors, tachycardia, palpitations, agitation, insomnia, weight loss despite good appetite, diarrhea, and recent illness (influenza) acting as a trigger. These symptoms indicate an acutely increased metabolic state.
• Place client on telemetry: Tachycardia and palpitations suggest cardiac involvement. Continuous cardiac monitoring helps detect life-threatening arrhythmias, such as atrial fibrillation, which are common in hyperthyroid crises.
• Initiate hydration therapy: Hypermetabolism, fever, and diarrhea can cause fluid loss and increase the risk for dehydration. Hydration supports perfusion and reduces cardiac strain during a hypermetabolic state.
• Cardiac dysrhythmias: Excess thyroid hormones increase the heart's sensitivity to catecholamines, heightening the risk for dysrhythmias. Monitoring rhythm helps identify complications early.
• Neurological status: Agitation, tremors, and insomnia may progress to delirium or seizures in thyroid storm. Regular neuro checks allow early recognition of worsening symptoms.

Rationale for incorrect choices:

• Hypoparathyroidism: This typically presents with signs of hypocalcemia such as tetany or paresthesias, not the metabolic hyperactivity seen here. The client's symptoms do not reflect this condition.
• Hyperparathyroidism: It usually causes hypercalcemia, bone pain, and kidney stones, none of which are evident. Diarrhea, fever, and cardiac signs are not typical.
• Hypothyroidism: Presents with fatigue, cold intolerance, constipation, bradycardia, and weight gain—opposite of this client’s hyperactive symptoms.
• Check for Chvostek and Trousseau’s signs: These are used to assess for hypocalcemia, which is not indicated in this scenario. There are no neuromuscular irritability symptoms present.
• Monitor for hypoglycemia: There's no indication of low blood sugar, and the client does not report symptoms like shakiness, confusion, or hunger related to hypoglycemia.
• Provide nutritional support: While the client has lost weight, the priority is stabilizing the acute condition (thyroid storm), not nutritional rehabilitation at this moment.
• Phosphorus levels: These are not directly affected in hyperthyroidism and monitoring them wouldn't provide information relevant to the current crisis.
• Weight gain: This client has experienced weight loss, and tracking weight gain is not a relevant short-term indicator of improvement in acute hyperthyroidism.
• Calcium levels: There is no evidence of calcium imbalance or parathyroid involvement, so monitoring calcium is not pertinent in this case.
