Answer to Question 1

D
The presence of blanching and the loss of peripheral pulses, sensation, or motor function in a limb indicate peripheral vascular thrombi. Neurologic signs and symptoms such as confusion, headache, and impaired speech can signal the onset of cerebral artery occlusion and stroke. Acute myocardial infarction may be heralded by dyspnea, chest pain, pallor, and alterations in blood pressure. Thrombi in the pulmonary vasculature may be evidenced by pleuritic pain, rales, and dyspnea.

Answer to Question 2

B
Frequent verification of the serum potassium concentration is required for patients with DKA receiving fluid resuscitation and insulin therapy. The serum phosphate level is sometimes low (hypophosphatemia) in DKA. Insulin treatment may make this more obvious as phosphate is returned to the interior of the cell. If the serum phosphate level is less than 1 mg/dL, phosphate replacement is recommended.
