HESI LPN
HESI Fundamentals Exam
1. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?
- A. Assess the client for a gag reflex
- B. Measure the pH of the gastric aspirate
- C. Place the end of the NG tube in water to observe for bubbling
- D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water
Correct answer: B
Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.
2. The nurse is preparing to administer a blood transfusion to a client. Which action should the LPN/LVN take to ensure the client's safety?
- A. Check the client's identification and blood type.
- B. Monitor the client's vital signs every hour during the transfusion.
- C. Administer the blood through a peripheral IV line.
- D. Verify the blood product with another nurse before administration.
Correct answer: D
Rationale: To ensure the client's safety during a blood transfusion, it is crucial to verify the blood product with another nurse before administration. This step helps confirm the correct blood type and prevents transfusion reactions. While checking the client's identification and blood type (Choice A) is important, the ultimate responsibility lies with confirming the blood product before administration. Monitoring vital signs (Choice B) is necessary during a transfusion but does not directly address verifying the blood product. Administering blood through a peripheral IV line (Choice C) is a common practice but does not specifically ensure that the correct blood product is being administered, which is essential for the client's safety.
3. A client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the LPN monitor closely while the client is taking this medication?
- A. Sodium
- B. Potassium
- C. Calcium
- D. Magnesium
Correct answer: B
Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.
4. While a client is receiving total parenteral nutrition (TPN), which of the following actions should the nurse take?
- A. Monitor the client's blood glucose level every 4 hours.
- B. Change the TPN tubing every 72 hours.
- C. Weigh the client daily.
- D. Change the TPN bag every 24 hours.
Correct answer: D
Rationale: The correct action is to change the TPN bag every 24 hours to reduce the risk of infection. Changing the TPN tubing every 72 hours (Choice B) may increase the risk of contamination. Monitoring the client's blood glucose level every 4 hours (Choice A) is important but not specific to TPN administration. Weighing the client daily (Choice C) is essential for monitoring fluid status but is not directly related to TPN administration.
5. While changing the linen on the client's bed, what should the nurse do?
- A. Hold the linen away from their body and clothing.
- B. Fold the linen neatly before placing it in the laundry.
- C. Wear clean gloves while handling the linen.
- D. Place the linen directly on the floor until the new linen is in place.
Correct answer: A
Rationale: When changing the linen on a client's bed, it is essential for the nurse to hold the linen away from their body and clothing. This practice helps prevent contamination and maintain a clean environment. Folding the linen neatly before placing it in the laundry (Choice B) is a good practice but not the immediate action required during linen changing. Wearing clean gloves while handling the linen (Choice C) is important in certain situations but may not be necessary for routine linen changing. Placing the linen directly on the floor until the new linen is in place (Choice D) is incorrect as it can lead to contamination and is not hygienic.
