HESI RN Medical Surgical Practice Exam
1. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?
- A. As a single-dose 200 mEq oral tablet
- B. As an intravenous bolus over 15 to 20 minutes
- C. In an intravenous solution at a rate of 10 mEq/hour
- D. In an intravenous solution at a rate of 45 mEq/hour
Correct answer: C
Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.
2. A client has a serum potassium level of 6.5 mmol/L, a serum creatinine level of 2 mg/dL, and a urine output of 350 mL/day. What is the best action by the nurse?
- A. Place the client on a cardiac monitor immediately.
- B. Teach the client to limit high-potassium foods.
- C. Continue to monitor the client’s intake and output.
- D. Ask to have the laboratory redraw the blood specimen.
Correct answer: A
Rationale: The best immediate action by the nurse in this situation is to place the client on a cardiac monitor immediately. A serum potassium level of 6.5 mmol/L indicates hyperkalemia, which can lead to life-threatening dysrhythmias. Monitoring the cardiac status is crucial to detect any potential arrhythmias promptly. Teaching the client to limit high-potassium foods (Choice B) may be important for long-term management, but it is not the priority at this moment. Continuing to monitor intake and output (Choice C) is important for assessing renal function but does not address the immediate risk of dysrhythmias. Asking to have the laboratory redraw the blood specimen (Choice D) is unnecessary since the current results indicate a critical situation that requires immediate action.
3. A client is scheduled for a barium swallow (esophagography) in 2 days. The nurse, providing preprocedure instructions, should tell the client to:
- A. Eat a regular supper and breakfast
- B. Remove all metal and jewelry before the test
- C. Expect diarrhea for a few days after the procedure
- D. Take all oral medications as scheduled with milk on the day of the test
Correct answer: B
Rationale: The correct answer is B: 'Remove all metal and jewelry before the test.' Before a barium swallow procedure, the client should fast for 8 to 12 hours to ensure the stomach and intestines are empty for optimal visualization. Removing all metal and jewelry is essential to prevent any interference with x-ray imaging. Choice A is incorrect because the client should fast, not eat supper and breakfast, before the test. Choice C is incorrect as diarrhea is not an expected outcome of a barium swallow. Choice D is incorrect as the client should not take any oral medications with milk on the day of the test to ensure accurate test results.
4. A client recovering from a cystoscopy is being assessed by a nurse. Which assessment findings should alert the nurse to urgently contact the health care provider? (Select all that apply.)
- A. Decrease in urine output
- B. Blood clots present in the urine
- C. Prescription for metformin
- D. A & B
Correct answer: D
Rationale: After a cystoscopy, the nurse should monitor urine output and promptly contact the provider if there is a decrease or absence of urine output. Additionally, the nurse should assess for blood in the urine. While some pink-tinged urine may be expected, the presence of gross bleeding or blood clots warrants immediate provider notification. Tolerating oral fluids is a positive sign and does not require urgent intervention. Metformin would be a concern if the client received contrast dye, which is not used in a cystoscopy. A burning sensation when urinating is a common post-procedure experience and does not necessitate contacting the provider. Therefore, choices A and B are the correct answers as they indicate potentially serious complications that require immediate attention, while choices C and D do not align with urgent concerns following a cystoscopy.
5. When obtaining the health history of a client suspected of having bladder cancer, which question should the nurse ask to determine the client's risk factors?
- A. Do you smoke cigarettes?
- B. Do you consume alcohol?
- C. Do you use recreational drugs?
- D. Do you take any prescription drugs?
Correct answer: A
Rationale: The correct answer is A: 'Do you smoke cigarettes?' Smoking is a major risk factor for bladder cancer. Cigarette smoke contains harmful chemicals that can accumulate in the urine and damage the lining of the bladder, increasing the risk of developing cancer. Alcohol use, recreational drug use, and most prescription drugs are not directly linked to an increased risk of bladder cancer. It is important for the nurse to assess smoking history as a significant risk factor in determining the client's risk for bladder cancer.
