HESI Fundamentals Practice Exam
1. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
2. The healthcare professional observes a UAP taking a client's blood pressure in the lower extremity. Which observation of this procedure requires the healthcare professional's intervention?
- A. The cuff wraps around the girth of the leg.
- B. The UAP auscultates the popliteal pulse with the cuff on the lower leg.
- C. The client is placed in a prone position.
- D. The systolic reading is 20 mm Hg higher than the blood pressure in the client's arm.
Correct answer: B
Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.
3. An unlicensed assistive personnel (UAP) places a client in a left lateral position prior to administering a soap suds enema. Which instruction should the nurse provide the UAP?
- A. Position the client on the right side of the bed in reverse Trendelenburg.
- B. Fill the enema container with 1000 ml of warm water and 5 ml of castile soap.
- C. Reposition the client in the Sims' position.
- D. Raise the side rails on both sides of the bed and elevate the bed to waist level.
Correct answer: C
Rationale: The correct position for administering a soap suds enema is the Sims' position, not the left lateral position. The Sims' position allows the enema solution to follow the anatomical course of the intestines and provides the best overall results. By repositioning the client in the Sims' position, the weight is distributed to the anterior ilium, facilitating the enema administration process.
4. What action should be implemented to prevent the formation of a sacral ulcer for an immobile client?
- A. Maintain the client in a lateral position using protective wrist and vest restraints.
- B. Position the client prone with a small pillow below the diaphragm.
- C. Raise the head and knee gatch when lying in a supine position.
- D. Transfer the client to a wheelchair close to the nursing station for observation.
Correct answer: B
Rationale: Positioning the client prone with a small pillow below the diaphragm helps maintain proper alignment and provides optimal pressure relief over the sacral area, reducing the risk of developing a pressure ulcer. This position redistributes pressure away from bony prominences, such as the sacrum, which is crucial in preventing ulcer formation in immobile clients. Choice A is incorrect because using restraints can lead to further complications and does not address pressure relief. Choice C is incorrect as raising the head and knee gatch in a supine position does not directly alleviate pressure over the sacrum. Choice D is incorrect as transferring to a wheelchair does not address pressure relief or optimal positioning to prevent sacral ulcers.
5. Which assessment data would provide the most accurate determination of proper placement of a nasogastric tube?
- A. Aspirating gastric contents to assure a pH value of 4 or less.
- B. Hearing air pass in the stomach after injecting air into the tubing.
- C. Examining a chest x-ray obtained after the tubing was inserted.
- D. Checking the remaining length of tubing to ensure that the correct length was inserted.
Correct answer: C
Rationale: The most accurate method to confirm the proper placement of a nasogastric tube is by examining a chest x-ray obtained after the tubing was inserted. This visual assessment allows healthcare providers to directly visualize the position of the tube in relation to anatomical landmarks, ensuring it is correctly placed in the stomach. Aspirating gastric contents or hearing air pass may provide some information but are not as definitive as a chest x-ray for confirming placement. Checking the remaining length of tubing is not a reliable method for determining proper placement as it does not indicate where the tip of the tube lies within the body.
