A dehydrated client quickly receives a liter of intravenous fluid infusion to increase circulating blood volume. The nurse would expect which changes in the client's vital signs?
1. A decrease in respiratory rate from 20 breaths/min to 12 breaths/min
2. A blood pressure decrease from 180/100 to 90/60
3. A pulse increase from 75 beats/min to 120 beats per minute
4. A blood pressure increase from 90/60 to 120/78
Correct Answer: 4
Rationale 1: The respiratory rate should not be affected by this intervention.
Rationale 2: Blood pressure is expected to increase, not decrease, after an intravenous infusion.
Rationale 3: The pulse should decrease if a volume-depleted client receives volume replacement.
Rationale 4: Infusion of intravenous fluids quickly increases blood volume and raises blood pressure.
Global Rationale: Infusion of intravenous fluids quickly increases blood volume and raises blood pressure. The respiratory rate should not be affected by this intervention. Blood pressure is expected to increase, not decrease, after an intravenous infusion. The pulse should decrease if a volume-depleted client receives volume replacement.
