The nurse is reinforcing teaching for a patient who is using a continuous passive motion (CPM) machine. Which of these, if stated by the patient, indicates to the nurse correct understanding of its purpose?

Choice A reason: A urine output of 18 mL/hr is significantly lower than the normal range (typically around 0.5-1 mL/kg/hr), indicating possible renal hypoperfusion, an early sign of shock.

Choice B reason: While blood pressure is an important indicator, it may not drop until later stages of shock.

Choice C reason: Lethargy can be a sign of shock, but it is a more subjective and later symptom compared to the objective measure of urine output.

Choice D reason: An elevated pulse is a compensatory mechanism in shock, but it is not as specific an early indicator as a decrease in urine output.

Choice A reason: While nutrition is important, it is not the immediate priority in the management of septic shock.

Choice B reason: Monitoring IV fluids is important, but the initial priority is to treat the infection causing the septic shock.

Choice C reason: Obtaining blood cultures is important, but it should not delay the administration of antibiotics.

Choice D reason: The administration of broad-spectrum antibiotics within one hour of diagnosing septic shock is critical to improve outcomes and is considered a priority action.
