A nurse is administering albumin to a client who has hypovolemic shock due to hemorrhage. The nurse understands that albumin is which of the following types of solutions?
Crystalloid.
Colloid.
Hypertonic.
Hypotonic.
The Correct Answer is B
Choice A reason:
Crystalloid solutions are fluids that contain electrolytes and can diffuse across semipermeable membranes. They are used to treat dehydration, electrolyte imbalances, and hypovolemia. However, they are not as effective as colloids in expanding the intravascular volume and maintaining the blood pressure. Therefore, choice A is incorrect.
Choice B reason:
Colloid solutions are fluids that contain large molecules such as proteins, starches, or gelatin that cannot cross the capillary membrane. They exert an osmotic pressure that draws fluid from the interstitial and intracellular spaces into the intravascular space. They are used to treat hypovolemic shock, burns, and hemorrhage. Albumin is a type of colloid solution that is derived from human plasma and contains 5% or 25% protein. It increases the plasma volume and the blood pressure by increasing the oncotic pressure. Therefore, choice B is correct.
Choice C reason:
Hypertonic solutions are fluids that have a higher osmolarity than the blood plasma. They draw water out of the cells and into the intravascular space. They are used to treat hyponatremia, cerebral edema, and severe dehydration. However, they can cause fluid overload, hypertension, and cellular dehydration if given in excess. Therefore, choice C is incorrect.
Choice D reason:
Hypotonic solutions are fluids that have a lower osmolarity than the blood plasma. They provide free water and electrolytes to the cells and the interstitial space. They are used to treat hypernatremia, cellular dehydration, and fluid loss due to burns or diuresis. However, they can cause fluid shifts from the intravascular space to the interstitial and intracellular spaces, resulting in hypovolemia, hypotension, and edema. Therefore, choice D is incorrect.

Correct Answer is ["A","B","C","D"]
Explanation
Choice A reason:
Jugular vein distension is a sign of fluid overload because it indicates increased pressure in the right atrium and superior vena cava due to excess blood volume.
Choice B reason:
Weight gain of 2 kg in one day is a sign of fluid overload because it reflects fluid retention in the body. A weight gain of 1 kg (2.2 lb) is equivalent to 1 L of fluid.
Choice C reason:
Decreased hematocrit is a sign of fluid overload because it indicates hemodilution or dilution of the blood due to excess fluid in the intravascular space.
Choice D reason:
Bounding pulse is a sign of fluid overload because it reflects increased cardiac output and stroke volume due to excess blood volume.
Choice E reason:
Flat neck veins are not a sign of fluid overload, but rather a sign of fluid deficit or dehydration. In fluid overload, neck veins will be distended or elevated.
Correct Answer is D
Explanation
Choice A reason:
Serum sodium is not directly related to the acid-base balance of the body. Sodium bicarbonate therapy does not affect the serum sodium level significantly. Therefore, monitoring serum sodium is not an effective way to evaluate the effectiveness of the therapy.
Choice B reason:
Serum potassium is inversely related to the serum pH. As the pH increases, the potassium level decreases, and vice versa. Sodium bicarbonate therapy raises the pH and lowers the potassium level. Therefore, monitoring serum potassium is important to prevent hypokalemia, but it does not directly reflect the acid-base balance of the body.
Choice C reason:
Serum chloride is inversely related to the serum bicarbonate level. As the bicarbonate level increases, the chloride level decreases, and vice versa. Sodium bicarbonate therapy increases the bicarbonate level and decreases the chloride level. Therefore, monitoring serum chloride is important to prevent hypochloremia, but it does not directly reflect the acid-base balance of the body.
Choice D reason:
Serum bicarbonate is directly related to the acid-base balance of the body. The normal range of serum bicarbonate is 22 to 26 mEq/L. In metabolic acidosis, the bicarbonate level is low, and in metabolic alkalosis, it is high. Sodium bicarbonate therapy aims to increase the bicarbonate level and correct metabolic acidosis. Therefore, monitoring serum bicarbonate is the most effective way to evaluate the effectiveness of the therapy.
