A client is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH).
The nurse would monitor the client for which of the following electrolyte imbalances?

SIADH is a condition in which your body makes too much antidiuretic hormone (ADH), which controls how your body releases and conserves water.

SIADH makes it harder for your kidneys to release water and causes the levels of electrolytes, like sodium, to fall due to water retention.

This leads to hyponatremia, which is when you have low levels of sodium in your blood.

Choice B is wrong because hypernatremia is when you have high levels of sodium in your blood.

This can occur due to dehydration, excessive salt intake, or kidney problems.

Choice C is wrong because hyperkalemia is when you have high levels of potassium in your blood.

This can occur due to kidney failure, acidosis, or certain medications.

Choice D is wrong because hypokalemia is when you have low levels of potassium in your blood.

This can occur due to vomiting, diarrhea, diuretics, or alkalosis.

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.
