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 D
Explanation
Nasogastric suction removes gastric secretions that contain potassium, leading to a loss of potassium from the body. This can cause hypokalemia, which is a low level of potassium in the blood.
Choice A is wrong because Addison’s disease causes hyperkalemia, which is a high level of potassium in the blood.
Choice B is wrong because tissue damage can release potassium from the cells into the blood, causing hyperkalemia.
Choice C is wrong because uric acid level is not related to potassium level.
Uric acid is a waste product of purine metabolism that can cause gout or kidney stones if elevated.
Correct Answer is B
Explanation
Hyponatremia is a condition where sodium levels in your blood are lower than normal. This can cause symptoms such as nausea, headache, confusion, muscle weakness and seizures. A hypertonic saline solution is a fluid that has a higher concentration of sodium than normal blood. It can help restore the sodium balance and prevent or treat the complications of hyponatremia.
Choice A is wrong because restricting fluid intake may not be enough to correct severe hyponatremia and may worsen the symptoms if the cause is sodium loss.
Choice C is wrong because encouraging increased fluid intake may further dilute the sodium levels and worsen the condition.
Choice D is wrong because administering a loop diuretic may increase the urine output and cause more sodium loss, leading to more severe hyponatremia.
Normal ranges for blood sodium levels are between 135 and 145 milliequivalents per liter (mEq/L).
