A nurse is caring for a client who has schizophrenia. The nurse should expect the client to exhibit which of the following manifestations? (Select all that apply.)

A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.

B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.

C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.

D. Lower urine specific gravity: Dehydration causes increased urine concentration, resulting in higher urine specific gravity, not lower.

- A: A heart rate greater than 60/min indicates that the transcutaneous pacing is effectively maintaining a heart rate within a normal range, which is crucial for adequate cardiac output and systemic perfusion.
- B: While 2+ pedal pulses indicate good peripheral perfusion, they do not directly reflect the effectiveness of transcutaneous pacing in treating complete heart block.
- C: Pacer spikes should appear before the QRS complex to show that the pacing stimulus is being delivered appropriately. Spikes after the QRS complex suggest that the pacing is not capturing the heart effectively.
- D: Distended jugular veins would be more indicative of heart failure or fluid overload and do not directly relate to the effectiveness of pacing therapy.
