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 C
Explanation
According to Healthline1 and Mayo Clinic, the normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L).
Choice A is wrong because it is the normal range for potassium, not sodium.
Choice B is wrong because it is the normal range for calcium, not sodium.
Choice D is wrong because it is the normal range for chloride, not sodium
Correct Answer is A
Explanation
Increased urine output is a sign of adequate hydration, as it means the kidneys are filtering waste and fluids from the body through the urine. The urine should be pale straw or lemonade colored, which indicates good hydration.
Choice B is wrong because decreased urine output is a sign of dehydration, as it means the kidneys are not working well and waste products are accumulating in the blood.
The urine may be dark and strong smelling, which indicates poor hydration.
Choice C is wrong because dry mucous membranes are a sign of dehydration, as they indicate a lack of fluid in the body tissues.
Choice D is wrong because hypertension is not a direct indicator of hydration status, although dehydration can cause low BP due to reduced blood volume.
