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 Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.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. A nurse is talking with an adolescent who is having difficulty dealing with several issues. Which of the following issues should the nurse identify as the priority?
- A. “I kind of like this boy in my class, but he doesn’t like me back.â€
- B. “I want to hang out with the kids in the science club, but the jocks pick on them.â€
- C. “I am so fat, I skip meals to try to lose weight.â€
- D. “My dad wants me to be a lawyer like him, but I just want to dance.â€
Correct answer: C
Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.
3. A client is reporting difficulty falling asleep. Which of the following measures should the nurse recommend?
- A. Drink a cup of hot cocoa before bedtime
- B. Exercise 1 hour before going to bed
- C. Use progressive relaxation techniques at bedtime
- D. Reflect on the day's activities before going to bed
Correct answer: C
Rationale: The correct answer is to recommend the client to use progressive relaxation techniques at bedtime. Progressive relaxation techniques help reduce stress and muscle tension, which can promote better sleep. Choice A, drinking a cup of hot cocoa before bedtime, contains caffeine which can interfere with falling asleep. Choice B, exercising 1 hour before going to bed, can stimulate the body and mind, making it harder to fall asleep. Choice D, reflecting on the day's activities before going to bed, may lead to increased mental activity and prevent relaxation, making it difficult to fall asleep.
4. During an IV catheter insertion demonstration, which statement by a nurse indicates understanding of the procedure?
- A. “I will thread the needle into the vein at an angle of 10 to 30 degrees with the bevel up.â€
- B. “I will insert the needle into the client’s skin at an angle of 10 to 30 degrees with the bevel up.â€
- C. “I will apply pressure approximately 1.2 inches below the insertion site before removing the needle.â€
- D. “I will select a vein in the antecubital fossa for IV insertion based on its size and easily accessible location.â€
Correct answer: B
Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.
5. A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulation therapy. Which of the following laboratory values would be most concerning?
- A. INR of 1.5
- B. Platelet count of 200,000/mm³
- C. Hemoglobin of 12 g/dL
- D. aPTT of 70 seconds
Correct answer: A
Rationale: An INR of 1.5 is below the therapeutic range for clients on anticoagulation therapy, increasing the risk of clot formation. A lower INR indicates inadequate anticoagulation, which can lead to thrombus formation and potential complications such as progression or recurrence of deep vein thrombosis. Platelet count, hemoglobin level, and aPTT are important parameters to monitor in a client with DVT. However, in this scenario, the most concerning value is the suboptimal INR level because it signifies a lack of anticoagulation effectiveness and poses a higher risk of clotting issues.
