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 B
Explanation
Respiratory acidosis.
Choice A rationale:
Metabolic alkalosis occurs when there is an increase in pH and bicarbonate (HCO₃⁻) levels, which is not the case here. The pH value in this scenario is 7.22, indicating acidosis.
Choice B rationale:
Respiratory acidosis results from the retention of carbon dioxide (PaCO₂) in the blood, leading to a decrease in pH. In this case, the pH is low (7.22), and the PacO₂ is elevated (68 mm Hg), supporting the diagnosis of respiratory acidosis.
Choice C rationale:
Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels, along with a possible negative base excess. However, in this scenario, the base excess is -2, which does not indicate metabolic acidosis.
Choice D rationale:
Respiratory alkalosis occurs when there is a decrease in PaCO₂, leading to an increase in blood pH. The ABG values provided (pH 7.22, PacO₂ 68 mm Hg) are not consistent with respiratory alkalosis.
Correct Answer is ["A","B","D"]
Explanation
The correct answer is choices A, B, and D. Here are the rationales for each choice:
Choice A rationale:
Sweet potatoes are an excellent source of potassium. One medium sweet potato contains about 542 mg of potassium, making it a great option for a high-potassium diet.
Choice B rationale:
Bananas are well-known for their high potassium content. A medium banana provides approximately 451 mg of potassium, which is beneficial for maintaining proper muscle and nerve function.
Choice C rationale:
Grapes are not particularly high in potassium compared to other fruits. They contain some potassium, but not enough to be considered a significant source for a high-potassium diet.
Choice D rationale:
Watermelon is a good source of potassium. Two wedges of watermelon contain about 640 mg of potassium, making it a suitable choice for increasing potassium intake.
