A nurse is caring for a client who has hypovolemic shock. Which of the following should the nurse recognize as an expected finding?
Hypertension
Bradypnea
Oliguria
Flushing of the skin
The Correct Answer is C
Choice A Reason: This is incorrect because hypertension is a condition of high blood pressure. A client who has hypovolemic shock is more likely to have hypotension, which is a condition of low blood pressure, due to fluid loss and reduced cardiac output.
Choice B Reason: This is incorrect because bradypnea is a condition of slow breathing. A client who has hypovolemic shock is more likely to have tachypnea, which is a condition of fast breathing, due to hypoxia and increased respiratory demand.
Choice C Reason: This is correct because oliguria is a condition of low urine output. A client who has hypovolemic shock may have oliguria due to decreased renal perfusion and activation of the renin-angiotensin-aldosterone system, which causes sodium and water retention.
Choice D reason: This is incorrect because flushing of the skin is a condition of redness and warmth of the skin. A client who has hypovolemic shock may have pallor and coolness of the skin due to vasoconstriction and reduced blood flow.

Correct Answer is A
Explanation
Choice A Reason: This is correct because an osmotic diuretic, such as mannitol, works by creating an osmotic gradient that draws fluid from the brain tissue into the blood vessels, thereby reducing cerebral edema and intracranial pressure.
Choice B Reason: This is incorrect because an osmotic diuretic would decrease, not increase, the cell size in the brain by removing fluid from the intracellular space.
Choice C Reason: This is incorrect because an osmotic diuretic would decrease, not expand, the extracellular fluid volume by increasing the urine output and excreting excess fluid from the body.
Choice D Reason: This is incorrect because an osmotic diuretic would not provide fluid hydration, but rather cause fluid loss and dehydration.
Correct Answer is A
Explanation
Choice A Reason: Packed RBCs are indicated for clients who have hypovolemic shock due to blood loss, as they increase the oxygen-carrying capacity of the blood and restore the blood volume.
Choice B Reason: Cryoprecipitates are indicated for clients who have hemophilia or von Willebrand disease, as they contain clotting factors that help stop bleeding.
Choice C Reason: Albumin is indicated for clients who have hypovolemic shock due to fluid loss, such as from burns or ascites, as it increases the plasma oncotic pressure and draws fluid into the vascular space.
Choice D Reason: Platelets are indicated for clients who have thrombocytopenia or platelet dysfunction, as they help prevent or control bleeding.
