HESI LPN
HESI Fundamental Practice Exam
1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
2. The healthcare provider is educating a client about dietary changes to prevent the recurrence of calcium oxalate kidney stones. Which food should the provider advise the client to avoid?
- A. Spinach
- B. Bananas
- C. Chicken
- D. Rice
Correct answer: A
Rationale: The correct answer is A: Spinach. Spinach is high in oxalate, a compound that can contribute to the formation of calcium oxalate kidney stones. Therefore, advising the client to avoid spinach is crucial in reducing the risk of stone recurrence. Bananas (choice B) are not high in oxalate and do not directly contribute to the formation of calcium oxalate stones, so they do not need to be avoided. Similarly, choices C and D, chicken, and rice, are not typically associated with high oxalate content, making them safe choices and do not need to be avoided specifically to prevent calcium oxalate kidney stones.
3. A client with Guillain-Barre syndrome is in a non-responsive state, yet vital signs are stable and breathing is independent. What should the nurse document to most accurately describe the client's condition?
- A. Comatose, breathing unlabored
- B. Glasgow Coma Scale 8, respirations regular
- C. Appears to be sleeping, vital signs stable
- D. Glasgow Coma Scale 13, no ventilator required
Correct answer: B
Rationale: The correct answer is B: 'Glasgow Coma Scale 8, respirations regular.' A Glasgow Coma Scale of 8 with regular respirations accurately describes a non-responsive state with independent breathing. Choice A is incorrect because 'comatose' implies a deep state of unconsciousness, which may not be accurate in this case. Choice C is incorrect as stating the client 'appears to be sleeping' may not accurately reflect the severity of the situation. Choice D is incorrect because a Glasgow Coma Scale of 13 would not typically correspond to a non-responsive state.
4. A nurse is preparing to check a client's blood pressure. Which of the following actions should the nurse take?
- A. Apply the cuff above the client's antecubital fossa.
- B. Use a cuff with a width that is about 60% of the client's arm circumference.
- C. Have the client sit with their arm resting at the level of their heart.
- D. Release the pressure on the client's arm at a rate of 5 to 6 mm per second.
Correct answer: A
Rationale: The correct action when checking a client's blood pressure is to apply the cuff above the client's antecubital fossa. Placing the cuff above this area allows for an accurate measurement of blood pressure. Choice B is incorrect because the cuff width should be approximately 40% of the arm circumference, not 60%. Choice C is incorrect as the client's arm should rest at heart level, not above it, to ensure an accurate reading. Choice D is incorrect as the pressure on the client's arm should be released at a rate of 2 to 3 mm per second, not 5 to 6 mm per second.
5. The nurse is assessing body alignment for a patient who is immobilized. Which patient position will the nurse use?
- A. Supine position
- B. Lateral position
- C. Lateral position with positioning supports
- D. Supine position with no pillow under the patient's head
Correct answer: B
Rationale: When assessing body alignment for an immobilized patient, the nurse should use the lateral position. This position helps in assessing alignment and preventing complications such as pressure ulcers. The supine position (Choice A) may not provide an accurate assessment of body alignment in an immobilized patient. While a lateral position with positioning supports (Choice C) may be used for comfort, it is not specifically for assessing body alignment. Using the supine position without a pillow under the patient's head (Choice D) is not ideal for assessing body alignment in an immobilized patient as it may not accurately reflect the patient's overall alignment.
