A nurse is assessing an older adult client at a health fair. Which of the following statements by the client is the nurse's priority?

Rationale for Correct Choices:

• Hyperthyroidism: The client's symptoms—including a high fever, chest pain, palpitations, tremors, tachycardia, weight loss, diarrhea, and hyperactive bowel sounds—are indicative of hyperthyroidism. The lab results showing elevated T3 and T4 with suppressed TSH further support this diagnosis..
• Place client on telemetry: Given the client's tachycardia (heart rate of 125/min), chest pain, and potential for arrhythmias (a common complication of hyperthyroidism), placing the client on telemetry is essential to monitor for any cardiac dysrhythmias.
• Initiate hydration therapy: Hyperthyroidism can lead to dehydration due to increased metabolic activity and diarrhea. The client has reported weight loss and diarrhea, indicating the need for fluid replacement.
• Cardiac dysrhythmias: Hyperthyroidism often causes tachycardia and increases the risk of arrhythmias, especially atrial fibrillation. Monitoring for cardiac dysrhythmias is crucial in this case to ensure the client’s heart rhythm is stable and to prevent complications.
• Neurological Status: The client is oriented x 3 but appears nervous, agitated, and has tremors. In thyroid storm, severe agitation, delirium, psychosis, and even coma can develop. Close monitoring of neurological status is essential to assess the severity of encephalopathy.

Rationale for Incorrect Choices:

• Hypoparathyroidism: Hypoparathyroidism typically causes symptoms such as muscle spasms, tetany, and hypocalcemia, which do not match the client’s presentation. The client has symptoms more consistent with hyperthyroidism.
• Hypothyroidism: Hypothyroidism is characterized by fatigue, weight gain, bradycardia, and cold intolerance, which is the opposite of what the client is presenting with. The lab results (elevated T3 and T4 levels) also exclude hypothyroidism as a possibility.
• Hyperparathyroidism: Hyperparathyroidism typically presents with hypercalcemia, muscle weakness, and fatigue. The client’s calcium levels are normal (9.5 mg/dL) and the clinical symptoms are more indicative of hyperthyroidism, not hyperparathyroidism.
• Provide nutritional support: While nutritional support may be needed for managing hyperthyroidism long-term, it is not the priority action in this acute setting. Immediate interventions should focus on stabilizing the patient’s heart rate and fluid balance.
• Check for Chvostek and Trousseau signs: Chvostek and Trousseau signs are used to assess for hypocalcemia, which is more relevant to conditions like hypoparathyroidism. In this case, hyperthyroidism is more likely, and these signs would not be helpful in this scenario.
• Monitor for hypoglycemia: While endocrine disorders can sometimes have overlapping symptoms or comorbidities, there's no specific indication or direct risk for hypoglycemia from hyperthyroidism in this presentation.
• Phosphorus levels: Phosphorus levels are typically monitored in cases involving kidney function, bone metabolism, or certain endocrine disorders like hypoparathyroidism or hyperparathyroidism, not hyperthyroidism.
• Weight gain: Weight gain is not relevant in the context of hyperthyroidism, where the typical presentation includes weight loss despite an increased appetite. Monitoring weight gain would be more appropriate in cases of hypothyroidism.
• Calcium levels: The client's calcium level is currently normal. While thyroid conditions can sometimes affect calcium, it's not the primary or most dynamic parameter to monitor for the acute phase and progress of thyroid storm compared to vital signs and mental status

Rationale:

• Skin turgor: In DKA, dehydration is a common result due to fluid loss from excessive urination and hyperglycemia. Decreased skin turgor, or slight tenting, is an indicator of dehydration. HHS is characterized by severe hyperglycemia and profound dehydration, leading to significant fluid deficits and impaired skin turgor.
• Blood glucose greater than expected reference range: Both DKA and HHS present with elevated blood glucose levels. The client's blood glucose level of 468 mg/dL is higher than the expected range. However, blood glucose levels tend to be much higher in HHS, sometimes exceeding 1000 mg/dL, while DKA usually ranges between 250–600 mg/dL.
• Blood pH: A blood pH of 7.30 is low and indicative of acidosis, which is a hallmark of DKA. In DKA, the body produces ketones as a byproduct of fat metabolism, which causes the blood pH to drop, leading to metabolic acidosis. HHS typically does not cause significant acidosis, and pH is generally within normal limits.
• Creatinine greater than expected reference range: Elevated creatinine levels suggest kidney impairment, which is common in DKA and HHS due to severe dehydration and osmotic diuresis. Dehydration significantly impairs renal perfusion and function, leading to elevated creatinine and BUN levels.
• Urine ketones: Ketones form when the body starts breaking down fat for energy due to a lack of insulin, which is characteristic of DKA. In HHS, the body does not typically produce significant amounts of ketones, as some insulin is still present and inhibiting fat metabolism.
