The nurse is admitting a patient who was diagnosed with acute renal failure. Which electrolyte should the nurse expect to be most affected with this disorder?
Phosphorous.
Magnesium.
Potassium.
Calcium.
The Correct Answer is C
Choice A rationale:
While acute renal failure can affect phosphorus levels, potassium is the electrolyte most commonly affected in this condition. Kidneys play a crucial role in regulating potassium levels in the body, and when they fail, potassium levels can become dangerously elevated.
Choice B rationale:
Acute renal failure can lead to alterations in magnesium levels, but potassium is typically more affected. Magnesium imbalances may occur but are not the primary concern in this condition.
Choice C rationale:
As mentioned earlier, potassium imbalances are common in acute renal failure. The nurse should closely monitor the patient's potassium levels and be prepared to intervene if they become too high or too low.
Choice D rationale:
Calcium levels may also be affected in acute renal failure, but potassium remains the most critical electrolyte to monitor in this condition.

Correct Answer is A
Explanation
Choice A rationale:
The arterial blood gas results show a low pH (acidosis) and an elevated Paco2 (partial pressure of carbon dioxide), which indicates respiratory acidosis. This condition occurs when there is inadequate removal of carbon dioxide through ventilation, leading to an accumulation of carbonic acid in the blood and a decrease in pH.
Choice B rationale:
Metabolic acidosis would present with a low pH and a low bicarbonate (HCO3-) level, not an elevated Paco2.
Choice C rationale:
Metabolic alkalosis would present with a high pH and an elevated bicarbonate (HCO3-) level, not an elevated Paco2.
Choice D rationale:
Respiratory alkalosis would present with a high pH and a decreased Paco2, not an elevated Paco2 as seen in this case.
Correct Answer is A
Explanation
Urine specific gravity 1.020.
Choice A rationale:
Urine specific gravity is a measure of urine concentration, indicating the ability of the kidneys to concentrate or dilute urine. A specific gravity of 1.020 falls within the normal range (typically 1.010 to 1.030). An appropriate specific gravity indicates that the client's kidneys are responding well to the IV fluids, maintaining adequate urine output and concentration.
Choice B rationale:
Potassium level of 5.2 mEq/L is above the normal range of 3.5 to 5 mEq/L. However, this value does not specifically indicate whether the client is responding effectively to the IV fluids for dehydration.
Choice C rationale:
Hct (Hematocrit) of 6296 is not a valid measurement; it appears to be a typographical error or an incomplete value. Therefore, it cannot be used to assess the client's response to treatment.
Choice D rationale:
Sodium level of 165 mEq/L is elevated beyond the normal range of 136 to 145 mEq/L. However, this value does not provide information about the client's response to IV fluids for dehydration.
