Which of the following would be the best indicator of adequate hydration?
Increased urine output.
Decreased urine output.
Dry mucous membranes.
Hypertension.
The Correct Answer is A
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.

Correct Answer is C
Explanation
This is because intravenous potassium supplementation is indicated for patients with profound hypokalemia (plasma K+ <2.5 mmol/L) or cardiac arrhythmia. The rate of infusion should not exceed 10 mmol/hour to prevent complications such as hyperkalemia, cardiac arrhythmias, and phlebitis.
Choice A is wrong because monitoring urine output every 8 hours is not sufficient to prevent complications from intravenous potassium replacement therapy.
Urine output should be monitored more frequently (at least every 4 hours) to assess renal function and fluid balance.
Choice B is wrong because administering potassium via a bolus injection is dangerous and can cause fatal cardiac arrhythmias.
Potassium should never be given by intravenous push or intramuscular injection.
Choice D is wrong because encouraging the client to eat potassium-rich foods is not appropriate for patients receiving intravenous potassium replacement therapy.
Oral potassium supplementation is preferred for patients with mild to moderate hypokalemia (plasma K+ 2.5-3.5 mmol/L) who can eat and absorb oral potassium.
Potassium-rich foods include potatoes, legumes, juices, seafood, leafy greens, dairy, tomatoes and bananas.
Correct Answer is C
Explanation
This is because acute renal failure is a condition where the kidneys lose their ability to filter waste and excess fluid from the blood. This can lead to fluid overload, electrolyte imbalances, and metabolic acidosis. Therefore, the nurse should monitor the patient’s urine output and fluid balance to assess the severity of the renal impairment and prevent complications.
Choice A is wrong because administering a potassium-sparing diuretic would worsen the patient’s hyperkalemia, which is a common complication of acute renal failure.
Choice B is wrong because encouraging the patient to consume a high-sodium diet would increase the patient’s fluid retention and blood pressure, which can further damage the kidneys.
Choice D is wrong because administering intravenous antibiotics is not a priority intervention for acute renal failure unless there is a specific indication of infection.
