Final answer:
The vital sign change that should alert the nurse that the client might be hemorrhaging is a blood pressure of 90/50.
Step-by-step explanation:
The vital sign change that should alert the nurse that the client might be hemorrhaging is a blood pressure of 90/50. A blood pressure reading of 90/50 is significantly lower than the normal range of 90/60 to 120/80 mm Hg, indicating a decrease in blood volume and potential hemorrhage.
Hemorrhaging is the loss of blood from the body, and it can lead to various complications if not addressed promptly. A decrease in blood pressure can be a sign of hemorrhaging because it indicates a decrease in the force exerted by the blood against the artery walls.
The nurse should assess the client further for other signs of hemorrhaging such as tachycardia (rapid heart rate), pale skin, cool and clammy extremities, and a decrease in urine output.
