The client has a history of renal failure and is receiving hemodialysis. The nurse should monitor for which electrolyte imbalance.
Hyperkalemia.
Hypokalemia.
Hyponatremia.
Hypernatremia.
The Correct Answer is A
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
Explanation
This is the only solution that is isotonic and compatible with blood products. It will not cause hemolysis or clotting of the blood cells.
Choice B is wrong because lactated Ringer’s is a balanced electrolyte solution that contains calcium, which can cause clotting of the blood cells.
Choice C is wrong because 5% dextrose is a hypotonic solution that can cause hemolysis of the blood cells.
Choice D is wrong because 5% dextrose in 0.45% sodium chloride is a hypertonic solution that can cause hemolysis of the blood cells.
Correct Answer is A
Explanation
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.
