Which vital sign change in a client with hypovolemic shock indicates to the nurse that the therapy is effective?

A) Urine output increases from 5 mL/hr to 25 mL/hr
B) Pulse pressure decreases from 35 mm Hg to 28 mm Hg
C) Respiratory rate increases from 22 breaths/min to 26 breaths/min
D) Core body temperature increases from 98.2 degrees F (36.8 degrees C) to 98.8 degrees F (37.1 degrees C)

An increase in urine output from 5mL/hr to 25mL/hr in a patient with hypovolemic shock indicates to the nurse that the therapy is effective. This is an important sign as it shows that the circulatory system is recovering and is able to deliver blood to the kidneys.

Explanation:

In the context of hypovolemic shock, the answer is A) Urine output increases from 5 mL/hr to 25 mL/hr. In hypovolemic shock, the body's system is trying to compensate for a loss of bodily fluids, often due to factors such as hemorrhage, diarrhea, extensive burns, or certain conditions like diabetes insipidus or ketoacidosis. The body generally reacts to such a situation with a rapid heart rate, a weak pulse, and restricted peripheral blood flow which make the skin cool and clammy, rapid and shallow breathing, and a dry mouth.

Therapies for hypovolemic shock typically involve intravenous fluid to help restore the patient's bodily function to its norm. Signs that the therapy is effective could include a gradual increase in urine output which signifies that the circulatory system is recovering and successfully delivering blood to the kidneys. This is deemed more critical than minor changes in body temperature, breathing rate, or pulse pressure, which can fluctuate for various reasons.
