Nursing Elites

1. A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?

• A. Albumin level of 2.5 g/dL
• B. Phosphorus level of 5 mg/dL
• C. Sodium level of 135 mmol/L
• D. Potassium level of 5.5 mmol/L

Correct answer: A

Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.

2. In a patient with chronic kidney disease, which of the following lab values would be expected?

• A. Elevated creatinine levels.
• B. Low hemoglobin levels.
• C. Elevated potassium levels.
• D. Low sodium levels.

Correct answer: A

Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.

3. The nurse is administering intravenous fluids to a dehydrated patient. On the second day of care, the patient's weight has increased by 2.25 pounds. The nurse would expect that the patient's fluid intake has

• A. equaled urine output.
• B. exceeded urine output by 1 L.
• C. exceeded urine output by 2.5 L.
• D. exceeded urine output by 3 L.

Correct answer: B

Rationale: A weight gain of 1 kg, or approximately 2.2 to 2.5 lb, is generally equivalent to 1 liter (L) of fluid retained by the body. In this case, the patient's weight gain of 2.25 pounds suggests an excess fluid retention of approximately 1 liter, indicating that the patient's fluid intake has exceeded urine output by 1 liter. Choices C and D are incorrect as they overestimate the fluid excess based on the patient's weight gain. Choice A is incorrect as it implies an exact balance between fluid intake and urine output, which is not reflected in the given weight increase.

4. 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.

5. In a client with heart failure presenting bilateral +4 edema of the right ankle extending up to midcalf while sitting with legs dependent, what is the priority goal?

• A. Decrease venous congestion.
• B. Maintain normal respirations.
• C. Maintain body temperature.
• D. Prevent injury to lower extremities.

Correct answer: A

Rationale: The priority goal in this scenario is to decrease venous congestion. By elevating the legs above the heart level, venous return is improved, reducing congestion in the lower extremities. This intervention helps decrease swelling and prevents complications such as impaired tissue perfusion. Maintaining normal respirations and body temperature are important aspects of care but are secondary to addressing the immediate issue of venous congestion. Preventing injury to lower extremities is also essential but takes precedence after managing the venous congestion to prevent further complications.
