HESI RN Medical Surgical Practice Exam
1. A client presents with a urine specific gravity of 1.018. What action should the nurse take?
- A. Evaluate the client’s intake and output for the past 24 hours.
- B. Document the finding in the chart and continue to monitor.
- C. Obtain a specimen for a urine culture and sensitivity.
- D. Encourage the client to drink more fluids, especially water.
Correct answer: B
Rationale: A urine specific gravity of 1.018 falls within the normal range, indicating adequate hydration. Therefore, the appropriate action is to document this finding in the client's chart and continue monitoring. There is no need to evaluate intake and output, as the specific gravity is normal. Obtaining a urine culture and sensitivity or encouraging increased fluid intake is unnecessary in this situation.
2. A client who underwent surgery and experienced significant blood loss is being cared for by a nurse. Which findings by the nurse should prompt immediate action to prevent acute kidney injury? (Select all that apply.)
- A. Urine output of 100 mL in 4 hours
- B. Large amount of sediment in the urine
- C. A & B
- D. Amber, odorless urine
Correct answer: C
Rationale: The nurse must monitor for signs of acute kidney injury in a postoperative client who had major blood loss. Low urine output, presence of sediment in the urine, and low blood pressure should raise concerns and be reported to the healthcare provider promptly. Postoperatively, assessing urine characteristics is crucial. Sediment, hematuria, and urine output less than 0.5 mL/kg/hour for 3 to 4 hours should be reported. While a urine output of 100 mL in 4 hours is low, it should be compared to the recommended 0.5 mL/kg/hour over a longer period. Perfusion to the kidneys is a priority, hence the importance of addressing low blood pressure. Amber, odorless urine is considered normal and does not indicate an immediate concern for acute kidney injury, unlike low urine output and presence of sediment.
3. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?
- A. Carbon dioxide is converted in the kidneys for elimination.
- B. Blood oxygen levels are stimulating the respiratory rate.
- C. Hyperventilation is eliminating carbon dioxide rapidly.
- D. High levels of carbon dioxide have accumulated in the blood.
Correct answer: D
Rationale: The correct answer is D. High levels of carbon dioxide in the blood are indicative of respiratory acidosis, often due to inadequate ventilation. In respiratory acidosis, there is retention of carbon dioxide (hypercapnia) leading to an increase in carbonic acid levels in the blood, resulting in an acidic pH. Option A is incorrect because carbon dioxide elimination primarily occurs through the lungs, not the kidneys. Option B is incorrect because blood oxygen levels primarily affect the respiratory rate to regulate oxygen levels, not carbon dioxide levels. Option C is incorrect because hyperventilation would lead to a decrease, not an increase, in carbon dioxide levels.
4. Which of the following conditions is the most significant risk factor for the development of type 2 diabetes mellitus?
- A. Cigarette smoking.
- B. High-cholesterol diet.
- C. Obesity.
- D. Hypertension.
Correct answer: C
Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.
5. The nurse is caring for a client who is scheduled for hemodialysis. Which of the following laboratory values should the nurse monitor closely before, during, and after the procedure?
- A. Hemoglobin level.
- B. Blood urea nitrogen (BUN) level.
- C. Creatinine level.
- D. Serum potassium level.
Correct answer: D
Rationale: The correct answer is D: Serum potassium level. Before, during, and after hemodialysis, monitoring the serum potassium level is crucial to prevent hyperkalemia, a potentially life-threatening complication. Hemodialysis is done to remove waste products and excess electrolytes like potassium from the blood. Monitoring other laboratory values like hemoglobin, BUN, and creatinine is important in assessing kidney function and anemia, but serum potassium level requires close monitoring during hemodialysis due to the risk of rapid shifts that can lead to cardiac arrhythmias.
