Nursing Elites

1. A client with chronic renal failure is on a low-protein diet. Which of the following is the best response by the nurse when the client asks why this diet is necessary?

• A. It reduces the workload on your kidneys.
• B. It helps prevent the buildup of waste products.
• C. It helps maintain electrolyte balance in your body.
• D. It helps prevent dehydration.

Correct answer: B

Rationale: A low-protein diet is necessary for clients with chronic renal failure because it helps prevent the buildup of waste products, such as urea, in the body. Excess protein can lead to the accumulation of waste products that the compromised kidneys may not effectively filter out, further burdening the already impaired renal function. Choices A, C, and D are incorrect because the primary reason for a low-protein diet in chronic renal failure is to reduce the workload on the kidneys by minimizing the production of waste products that can exacerbate the condition, not specifically to reduce kidney workload, maintain electrolyte balance, or prevent dehydration.

2. The healthcare provider is assessing a client with chronic renal failure who is receiving hemodialysis. Which of the following findings would indicate that the client is experiencing a complication of the treatment?

• A. Clear dialysate outflow.
• B. Blood pressure of 150/90 mm Hg.
• C. Increased heart rate.
• D. Fatigue.

Correct answer: B

Rationale: A blood pressure of 150/90 mm Hg during hemodialysis may indicate fluid overload or an ineffective dialysis session, which can lead to complications such as heart failure or pulmonary edema. This finding should be reported promptly for further evaluation and intervention. Clear dialysate outflow is a normal and expected finding during hemodialysis, indicating proper filtration of waste products. Increased heart rate can be a normal compensatory response to hemodialysis due to fluid shifts and should be monitored but does not necessarily indicate a complication. Fatigue is a common symptom in clients with chronic renal failure undergoing hemodialysis and is not specific to complications of the treatment.

3. Blood is drawn from a client with suspected uric acid calculi for a serum uric acid determination. Which value does the nurse recognize as a normal uric acid level?

• A. 1.7 mg/dL
• B. 5.8 mg/dL
• C. 8.9 mg/dL
• D. 12.8 mg/dL

Correct answer: B

Rationale: The normal range for uric acid is 4.5 to 8 mg/dL for males and 2.5 to 6.2 mg/dL for females. A uric acid level of 5.8 mg/dL falls within the normal range. Choices A, C, and D are outside the normal reference range, making them incorrect. Choice B is the correct answer as it aligns with the typical uric acid levels in the blood.

4. A client has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?

• A. Pulse rate
• B. Blood pressure
• C. Pulmonary artery systolic pressure
• D. Pulmonary artery end-diastolic pressure

Correct answer: A

Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.

5. Which electrolyte imbalance is most likely to be seen in a patient with chronic kidney disease?

• A. Hypernatremia.
• B. Hyperkalemia.
• C. Hypocalcemia.
• D. Hypokalemia.

Correct answer: B

Rationale: In chronic kidney disease, hyperkalemia is the most common electrolyte imbalance due to the kidneys' reduced ability to excrete potassium. This impaired kidney function leads to potassium retention in the body, resulting in elevated serum potassium levels. Hypernatremia (increased sodium levels) is less likely in chronic kidney disease as the kidneys typically still function to regulate sodium levels. Hypocalcemia (low calcium levels) is not a prominent electrolyte imbalance in chronic kidney disease unless there are additional factors involved. Hypokalemia (low potassium levels) is less common in chronic kidney disease, as the primary issue is usually potassium retention rather than deficiency.
