A nurse is caring for a client who has positive manifestations of schizophrenia. Which of the following behaviors should the nurse anticipate?

Choice A reason: This statement is incorrect because it suggests that higher oxygen levels trigger breathing, which is not the case in hypoxic drive.

Choice B reason: While carbon dioxide levels do influence breathing, this statement is not accurate in the context of hypoxic drive, which is specifically about oxygen levels.

Choice C reason: This choice is incorrect because the client does notice the need to breathe, but the trigger is low oxygen rather than high carbon dioxide levels.

Choice D reason: This is correct. In clients with COPD, chronic high levels of carbon dioxide can lead to a reliance on low oxygen levels to stimulate breathing.

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.
