Answer

Consider performing chest radiography to evaluate for pulmonary congestion or edema, if clinically indicated.

Renal ultrasound typically reveals nonspecific findings (eg, increased echogenicity) and is of little use. Ultrasonography may be helpful if the diagnosis is uncertain or if one needs evaluation of blood flow in the large renal vessels.

Abdominal ultrasonography or CT scanning may help if clinical findings raise suspicion of intestinal obstruction or perforation.

Noncontrast CT scanning or MRI of the head is indicated in patients with CNS symptoms or acute mental status changes. [7] Avoid iodinated contrast or gadolinium in patients with decreased renal function.
