HESI Fundamentals Exam Questions
Question 1 of 5
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?
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 Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.
Question 2 of 5
A client with iron-deficiency anemia asks a nurse why the Z-track method is necessary for administering iron dextran. Which response should the nurse provide?
Correct Answer: C
Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.
Question 3 of 5
In an emergency department, a nurse is assessing a client who reports right lower quadrant pain, nausea, and vomiting for the past 48 hours. Which of the following actions should the nurse take first?
Correct Answer: A
Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.
Question 4 of 5
During a Weber test, what is an appropriate action for the nurse to take?
Correct Answer: B
Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.
Question 5 of 5
A client reports mild back pain after receiving analgesia 1 hour ago. Which non-pharmacological pain method should the nurse plan to use?
Correct Answer: C
Rationale: In this scenario, the nurse should instruct the client to take deep rhythmic breaths as a non-pharmacological pain management method. Deep breathing can help the client relax, reduce stress, and manage pain effectively. Applying heat or ice for prolonged periods can lead to tissue damage. Removing distractions can be helpful for promoting relaxation but may not directly address the pain itself.
