HESI RN Medical Surgical Practice Exam Questions
Question 1 of 5
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?
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.
Question 2 of 5
After educating a client with a history of renal calculi, the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the teaching?
Correct Answer: A
Rationale:
To prevent the formation of renal calculi, it is essential to maintain adequate hydration as dehydration can contribute to the precipitation of minerals leading to stone formation.
Therefore, the correct statement indicating understanding of the teaching is choice A. Increasing fluid intake helps dilute urine and reduces the risk of stone formation. Eliminating all sources of calcium is not recommended as calcium is essential for various bodily functions and eliminating it can lead to other health issues. Aspirin and aspirin-containing products do not directly cause kidney stones. Antibiotics are not used to prevent or treat renal calculi, as they are not caused by bacterial infections.
Question 3 of 5
A client with a chest tube attached to a closed drainage system has undergone a chest x-ray, which revealed that the affected lung is fully reexpanded. The nurse anticipates that the next assessment of the chest tube system will reveal:
Correct Answer: A
Rationale: When the client's lung is fully reexpanded, the chest tube drainage system will no longer be actively draining, and there will be no fluctuation in the water seal chamber. Option B, continuous bubbling in the water seal chamber, indicates an air leak in the system, which is not expected when the lung is fully expanded. Option C, increased drainage in the collection chamber, would not be expected when the lung is reexpanded as there should be minimal to no drainage. Option D, continuous gentle suction in the suction control chamber, would not be appropriate when the lung is fully reexpanded and the chest tube is typically on a water seal system at this point to promote reexpansion and prevent air from entering the pleural space.
Question 4 of 5
After a lumbar puncture, into which position does the nurse assist the client?
Correct Answer: A
Rationale: After a lumbar puncture, the client should be positioned flat. This position helps prevent post-procedure spinal headaches and cerebrospinal fluid leakage. Keeping the client flat for up to 12 hours is crucial in minimizing these risks.
Choices B, C, and D are incorrect because elevating the head of the bed or sitting up can increase the risk of complications by altering the pressure in the spinal canal, potentially leading to headaches and fluid leakage.
Question 5 of 5
A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?
Correct Answer: A
Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity.
Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.
