72. The primary care provider assesses a patient at the office with a calcium concentration of 16.0 mg/dL, nausea, and vomiting. What does the provider do first for this patient?
Answer: C
Immediate referral to an emergency department
In a patient presenting with a calcium concentration of 16.0 mg/dL, which is significantly elevated, along with symptoms such as nausea and vomiting, the first step is to refer the patient to an emergency department. This condition, likely indicative of hypercalcemia, requires urgent medical attention due to potential severe complications.
A) Gastroscopy
Gastroscopy is a procedure used to examine the upper gastrointestinal tract but is not appropriate in this context. The symptoms of nausea and vomiting, combined with elevated calcium levels, suggest a metabolic emergency that needs immediate evaluation rather than an endoscopic procedure.
B) Emergency comprehensive blood test and glucose
While a comprehensive blood test may be useful in evaluating the underlying cause of hypercalcemia, it is not the immediate action needed in this scenario. The patient's condition is urgent, and stabilization in an emergency setting takes precedence over further laboratory evaluation.
C) Immediate referral to an emergency department
This option is correct as it prioritizes the patient's immediate health needs. Hypercalcemia can lead to serious complications such as cardiac arrhythmias and renal failure, necessitating emergency treatment and further assessment that can only be provided in a hospital setting.
D) Electroencephalogram
An electroencephalogram (EEG) is used to assess electrical activity in the brain and is not relevant in this case. The symptoms and lab results do not indicate a neurological issue that would warrant an EEG; instead, the focus should be on managing the hypercalcemia.
Conclusion
The immediate referral to an emergency department is the most appropriate course of action given the patient's critical condition characterized by severe hypercalcemia. Other options do not address the urgency of the situation or are not relevant to the presented symptoms, highlighting the necessity of prompt medical intervention to prevent serious health complications.
