A client is receiving intravenous fluid therapy with 0.9% sodium chloride solution.
The nurse understands that this type of solution is classified as:
Hypotonic.
Isotonic.
Hypertonic.
Colloid.
Colloid.
The Correct Answer is B
An isotonic solution has the same concentration of solutes as the blood plasma. 0.9% sodium chloride solution is an example of an isotonic solution.
It is used to supply water and salt to the body and to prevent hypotension induced by spinal anaesthesia.
Choice A is wrong because a hypotonic solution has a lower concentration of solutes than the blood plasma.
It can cause water to move into the cells and cause them to swell.
Choice C is wrong because a hypertonic solution has a higher concentration of solutes than the blood plasma.
It can cause water to move out of the cells and cause them to shrink.
Choice D is wrong because a colloid solution contains large molecules that do not pass through the capillary walls.
It is used to increase the blood volume and pressure in cases of shock or severe blood loss.

Correct Answer is A
Explanation
This is because hemodialysis removes excess fluid and waste products from the blood, but it also removes some electrolytes, such as potassium.
Potassium is important for nerve and muscle function, especially the heart.
If potassium levels are too high or too low, it can cause irregular heartbeat or cardiac arrest.
Choice B is wrong because hypokalemia means low potassium levels, which is unlikely in renal failure unless there is excessive potassium loss from diarrhea, vomiting or diuretics.
Choice C is wrong because hyponatremia means low sodium levels, which can occur in renal failure due to fluid retention, but it is not directly related to hemodialysis.
Choice D is wrong because hypernatremia means high sodium levels, which can occur in renal failure due to reduced urine output, but it is also not directly related to hemodialysis.
Normal ranges for electrolytes are: Potassium: 3.5 to 5.0 mmol/L
Sodium: 135 to 145 mmol/L
Calcium: 8.5 to 10.5 mg/dL
Chloride: 96 to 106 mmol/L
Magnesium: 1.7 to 2.2 mg/dL
Phosphate: 2.5 to 4.5 mg/dL
Bicarbonate: 22 to 29 mmol/L
Correct Answer is ["A","B","D"]
Explanation
These are all signs and symptoms of hypokalemia, which is a condition where the blood potassium level is too low. This can affect the function of the muscles, nerves, and heart. Therefore, the nurse would expect to find these signs and symptoms in a client with dehydration and hypokalemia.
Choice C is wrong because hyperreflexia is not a sign or symptom of hypokalemia.
Hyperreflexia is a condition where the reflexes are exaggerated or overactive.
This can be caused by conditions such as spinal cord injury, stroke, or electrolyte imbalances such as hypocalcemia or hypomagnesemia.
