HESI LPN
HESI Practice Test for Fundamentals
1. An elderly male client who is unresponsive following a cerebral vascular accident (CVA) is receiving bolus enteral feedings through a gastrostomy tube. What is the best client position for the administration of bolus tube feedings?
- A. Prone.
- B. Fowler's.
- C. Sims'.
- D. Supine.
Correct answer: B
Rationale: The correct answer is Fowler's position. Placing the client in Fowler's position, with the head of the bed elevated to 45-60 degrees, reduces the risk of aspiration during bolus enteral feedings by facilitating the flow of the feeding into the stomach. Prone position (choice A) is lying face down, which is not suitable for feeding. Sims' position (choice C) is a side-lying position used for rectal examinations or enemas, not for feeding. Supine position (choice D) is lying flat on the back and is not optimal for reducing the risk of aspiration during bolus tube feedings.
2. When should the nurse plan to collect a sputum specimen for culture and sensitivity as ordered by a client's provider?
- A. In the morning upon rising.
- B. Immediately after the client eats breakfast.
- C. Before the client goes to bed.
- D. After the client has had a drink of water.
Correct answer: A
Rationale: The correct time to collect a sputum specimen for culture and sensitivity is in the morning upon rising. This timing ensures the most concentrated sample as sputum produced overnight tends to accumulate and sit in the airways, providing a quality sample for testing. Collecting the specimen immediately after eating breakfast (choice B) may introduce food particles that could contaminate the sample. Collecting it before bed (choice C) may lead to a diluted sample due to daily activities. Collecting the specimen after having a drink of water (choice D) can also result in a diluted sample, impacting the accuracy of the test results.
3. 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.
4. A client has recently started using a behind-the-ear hearing aid. Which of the following statements should the nurse identify as an indication that the client understands the use of this assistive device?
- A. This type of hearing aid allows for fine-tuning of volume.
- B. I should ensure the hearing aid stays secure during exercise.
- C. I might hear a whistling sound when I first insert the hearing aid.
- D. I will be sure to remove my hearing aid before taking a shower.
Correct answer: D
Rationale: The correct answer is D because removing the hearing aid before taking a shower is essential to prevent water damage, as moisture can harm the device. Choice A is incorrect because behind-the-ear hearing aids do allow for fine-tuning of volume. Choice B is incorrect because exercise may cause the hearing aid to shift position, so it's important to ensure it stays secure. Choice C is incorrect because hearing a whistling sound when inserting the hearing aid may indicate improper placement or fit.
5. Why should a client with an ileal conduit be instructed to empty the collection device frequently?
- A. Force urine to back up into the kidneys.
- B. Suppress production of urine.
- C. Cause the device to pull away from the skin.
- D. Tear the ileal conduit
Correct answer: C
Rationale: A full urine collection bag can cause the device to pull away from the skin, leading to potential leakage and skin irritation. Choice A is incorrect because a full urine collection bag does not force urine to back up into the kidneys. Choice B is incorrect as a full collection bag does not suppress the production of urine. Choice D is incorrect as a full collection bag is unlikely to tear the ileal conduit.
