Nursing Elites

1. The client with chronic renal failure who is on a low-sodium diet should avoid which of the following foods?

• A. Fresh fruits.
• B. Canned soups.
• C. Lean meats.
• D. Whole grain bread.

Correct answer: B

Rationale: Canned soups are high in sodium, which can lead to fluid retention and hypertension in clients with chronic renal failure who are on a low-sodium diet. Fresh fruits, lean meats, and whole grain bread are generally lower in sodium and can be included in a low-sodium diet. Lean meats provide essential protein, fresh fruits offer vitamins and minerals, and whole grain bread provides fiber, making them suitable choices for individuals with chronic renal failure.

2. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.

3. A client with cardiovascular disease is scheduled to receive a daily dose of furosemide (Lasix). Which potassium level would cause the nurse to contact the physician before administering the dose?

• A. 3.0 mEq/L
• B. 3.8 mEq/L
• C. 4.2 mEq/L
• D. 5.1 mEq/L

Correct answer: A

Rationale: The normal serum potassium level in adults ranges from 3.5 to 5.1 mEq/L. A potassium level of 3.0 mEq/L is low, indicating hypokalemia and necessitating physician notification before administering furosemide, a loop diuretic that can further lower potassium levels. Potassium levels of 3.8 and 4.2 mEq/L are within the normal range, while a level of 5.1 mEq/L is high (hyperkalemia), but the critical value in this case is the low potassium level that requires immediate attention to prevent potential complications.

4. The provider has ordered Kayexalate and sorbitol to be administered to a patient. The nurse caring for this patient would expect which serum electrolyte values prior to administration of this therapy?

• A. Sodium 125 mEq/L and potassium 2.5 mEq/L
• B. Sodium 150 mEq/L and potassium 3.6 mEq/L
• C. Sodium 135 mEq/L and potassium 6.9 mEq/L
• D. Sodium 148 mEq/L and potassium 5.5 mEq/L

Correct answer: C

Rationale: Severe hyperkalemia, with a potassium level of 6.9 mEq/L, requires aggressive treatment with Kayexalate and sorbitol to increase the body’s excretion of potassium. The normal range for serum potassium is 3.5 to 5.5 mEq/L, so patients with the other potassium levels would not be treated aggressively or would need potassium supplementation. Therefore, option C (Sodium 135 mEq/L and potassium 6.9 mEq/L) is the correct choice as it indicates severe hyperkalemia warranting the administration of Kayexalate and sorbitol. Options A, B, and D have either potassium levels within normal limits, which would not necessitate this aggressive treatment, or potassium levels that are lower than what would typically prompt the need for Kayexalate and sorbitol.

5. In a patient with liver cirrhosis, which of the following lab results would be expected?

• A. Increased bilirubin levels.
• B. Decreased albumin levels.
• C. Increased liver enzymes.
• D. Decreased platelet count.

Correct answer: A

Rationale: In a patient with liver cirrhosis, increased bilirubin levels would be expected. Liver cirrhosis leads to impaired liver function, causing a decrease in the liver's ability to process bilirubin, leading to its accumulation in the blood. This results in elevated bilirubin levels. Decreased albumin levels (choice B) may occur in liver cirrhosis due to impaired liver synthesis of proteins, but it is not as specific as increased bilirubin levels. Increased liver enzymes (choice C) can be seen in liver damage but are not as characteristic as elevated bilirubin levels. Decreased platelet count (choice D) can occur in liver cirrhosis due to hypersplenism, but it is not as specific as increased bilirubin levels in this context.
