HESI LPN
HESI Practice Test for Fundamentals
1. 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.
2. A client is admitted for evaluation and control of HTN. Several hours after the client's admission, the nurse discovers the client supine on the floor, unresponsive to verbal or painful stimuli. The nurse's first reaction at this time is to:
- A. Establish an airway
- B. Call for assistance
- C. Check the client's pulse and blood pressure
- D. Perform CPR
Correct answer: A
Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.
3. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hr. The professional should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 107 mL/hr
- B. 120 mL/hr
- C. 95 mL/hr
- D. 100 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, divide the total volume (750 mL) by the total time (7 hr). 750 ÷ 7 ≈ 107 mL/hr. Choice A is correct because it accurately calculates the infusion rate based on the total volume and time. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate in this scenario.
4. The nurse is caring for a patient who is immobile and needs to be turned every 2 hours. The patient has poor lower extremity circulation, and the nurse is concerned about irritation of the patient's toes. Which device will the nurse use?
- A. Hand rolls
- B. A foot cradle
- C. A trapeze bar
- D. A trochanter roll
Correct answer: B
Rationale: A foot cradle is the correct choice for this situation. A foot cradle is used to reduce pressure on the tips of a patient's toes in individuals with poor lower extremity circulation. Hand rolls are not designed to address toe irritation specifically. A trapeze bar is used to assist patients with repositioning in bed, and a trochanter roll is used to support the hips and prevent external rotation of the legs, neither of which directly address toe irritation in this scenario.
5. A client with a history of seizures is prescribed phenytoin (Dilantin). Which statement should the LPN/LVN include when teaching the client about this medication?
- A. Do not take the medication with milk to avoid reduced absorption.
- B. Brush and floss your teeth regularly to prevent gum disease.
- C. Avoid taking antacids within 2 hours of the medication.
- D. Report any unusual bleeding or bruising to the healthcare provider.
Correct answer: C
Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.
