A 13-year-old patient presents to the emergency department in a disoriented state with tachycardia, tachypnea, hypotension, and hypothermia. Upon assessment, the nurse notes the patient’s breath smells like acetone, the mucous membranes are dry, and the patient has poor skin turgor. The nurse knows which test is the priority?

The patient walks into to the emergency department (ED) complaining of significant pain in the right eye. It appears red and swollen. The pupils are not equal in size or reactivity – the right pupil remains dilated despite the bright exam room and the flash light. The patient cringes from the bright light, though, and complains the bright lights are hurting his head. He reports that over the last week, both eyes have been aching and he has been seeing halos around lights. The nurse prepares for which test to be performed first?

The 56-year-old intubated and sedated patient’s arterial blood gas results are as follows: pH = 7.25, PCO2 = 36, PaO2 = 50, HCO3- = 15, SaO2 = 86%. Other lab values are notable for a hemoglobin of 7.9 mg/dL, albumin of 2.5 g/dL, sodium of 152 mEq/L, potassium of 2.1 mEq/L, chloride of 118 mEq/L. Vital signs are notable for a heart rate of 118 bpm, blood pressure of 86/38 mmHg, temperature of 102°F, and pulse oximetry of 85% on room air. The nurse advocates for which order?
