Question 72

Immediate referral to an emergency department

In cases of significantly elevated calcium levels, such as the patient's calcium concentration of 16.0 mg/dL, immediate referral to an emergency department is crucial for further evaluation and management of potential complications associated with hypercalcemia.

A) Gastroscopy

Gastroscopy is a procedure used to examine the upper gastrointestinal tract and is not immediately relevant in this situation. The patient's symptoms of nausea and vomiting could be due to hypercalcemia, but a gastroscopy would not address the underlying cause or the urgent need for treatment.

B) Emergency comprehensive blood test and glucose

While obtaining blood tests is important, in this scenario, it is not the first step. The patient's hypercalcemia is severe and requires immediate intervention rather than just additional testing, which can delay necessary treatment.

C) Immediate referral to an emergency department

This option is the most appropriate first step. The patient exhibits symptoms of severe hypercalcemia, which can lead to life-threatening complications if not addressed promptly. An emergency department is equipped to provide the necessary urgent care and interventions.

D) Electroencephalogram

An electroencephalogram (EEG) is used to evaluate electrical activity in the brain. This option is not suitable in this context, as it does not address the immediate medical issues related to the patient's elevated calcium levels or associated symptoms.

Conclusion

Immediate referral to an emergency department is the correct action due to the potential severity of the patient's hypercalcemia and associated symptoms. Other options either do not provide timely intervention or are irrelevant to the patient's critical condition. Prompt action is essential in such cases to prevent complications and ensure appropriate treatment.
