Question 1 of 5
A patient with septic shock has a BP of 70/46 mm Hg, pulse of 136 beats/min, respirations of 32 breaths/min, temperature of 104°F, and blood glucose of 246 mg/dL. Which intervention ordered by the health care provider should the nurse implement first?
Correct Answer: C
Rationale: Fluid resuscitation with normal saline is the priority in septic shock to address hypotension and restore perfusion.
Question 2 of 5
Which action should the nurse take first when the low pressure alarm sounds for a patient who has an arterial line in the left radial artery?
