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 B
Explanation
Choice A: Hypercalcemia. This is a condition of having too much calcium in the blood. It can cause muscle weakness, constipation, nausea, vomiting, confusion, and irregular heartbeat. However, it does not typically cause paresthesias (tingling or numbness), diarrhea, or crackles in the lungs.
Choice B:
Hypokalemia. This is a condition of having too low potassium in the blood. It can cause muscle weakness, paresthesias, irregular heartbeat, shallow respirations, and increased risk of digoxin toxicity (a medication used to treat heart failure) It can also cause vomiting and diarrhea, which can worsen the potassium loss. This choice matches the symptoms of the patient.
Choice C:
Hypermagnesemia. This is a condition of having too much magnesium in the blood. It can cause muscle weakness, nausea, vomiting, low blood pressure, bradycardia (slow heart rate), and respiratory depression. However, it does not usually cause paresthesias, diarrhea, or crackles in the lungs.
Choice D:
Hypophosphatemia. This is a condition of having too low phosphate in the blood. It can cause muscle weakness, bone pain, rickets (softening of bones), and impaired cellular function. However, it does not typically cause paresthesias, irregular heartbeat, shallow respirations, or crackles in the lungs.
Correct Answer is ["A","B","C"]
Explanation
Choice A reason:
The nurse should monitor blood glucose levels because dextrose 10% in water (D10W) is a hypertonic solution that contains glucose and can raise the blood sugar level of the patient. The nurse should check the blood glucose level before and after administering D10W to prevent hyperglycemia or hypoglycemia.
Choice B reason:
The nurse should check for signs of phlebitis at the IV site because D10W is acidic and can cause venous irritation. Phlebitis is inflammation of the vein that can result from chemical, mechanical or bacterial causes. Signs of phlebitis include pain, redness, swelling, warmth and tenderness at the IV site.
Choice C reason:
The nurse should assess for fluid overload because D10W is quickly metabolized, leaving behind water that can move into the interstitial space. Fluid overload can cause edema, dyspnea, crackles, distended neck veins, increased blood pressure and decreased urine output. The nurse should monitor the intake and output, vital signs, weight and breath sounds of the patient.
Choice D reason:
The nurse does not need to evaluate serum sodium levels because D10W does not contain sodium or affect the sodium balance of the patient. D10W is used to provide some nutrition with glucose, not to correct electrolyte imbalances.
Choice E reason:
The nurse does not need to observe for signs of hypoglycemia because D10W is unlikely to cause hypoglycemia unless there is a sudden interruption or discontinuation of the infusion. Hypoglycemia is a low blood sugar level that can cause shakiness, diaphoresis, confusion, weakness, hunger and headache. The nurse should monitor the blood glucose level and administer D10W at a steady rate to prevent hypoglycemia.
