HESI LPN
HESI Practice Test for Fundamentals
1. The healthcare provider is assessing a client diagnosed with rheumatoid arthritis. Which assessment finding would be most concerning?
- A. Morning stiffness
- B. Joint deformities
- C. Weight loss
- D. Fever
Correct answer: D
Rationale: Fever in a client with rheumatoid arthritis can indicate an underlying infection or a more serious systemic involvement, such as vasculitis or inflammation of internal organs. These conditions can lead to serious complications and require immediate medical attention. Joint deformities and morning stiffness are common manifestations of rheumatoid arthritis itself and may not be indicative of an acute issue. Weight loss can be seen in chronic inflammatory conditions like rheumatoid arthritis but is not as concerning as fever, which suggests an acute process requiring prompt evaluation and intervention.
2. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?
- A. The nurse opens the sterile field on a wet surface.
- B. The nurse turns away from the sterile field.
- C. The nurse uses a non-sterile glove to touch the sterile field.
- D. The nurse touches the edge of the sterile drape with her hand.
Correct answer: A
Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.
3. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:
- A. Refrigerates the collected specimen
- B. Collects the specimen in a sterile container
- C. Delays the collection of the specimen
- D. Uses a non-contaminated collection container
Correct answer: A
Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
4. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid-volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?
- A. Increase in hematocrit
- B. Increase in respiratory rate
- C. Decrease in heart rate
- D. Decrease in capillary refill time
Correct answer: C
Rationale: Fluid-volume deficit causes tachycardia. With correction of the imbalance, the heart rate should return to the expected range. An increase in hematocrit (Choice A) would indicate hemoconcentration, not a successful fluid replacement. An increase in respiratory rate (Choice B) could indicate respiratory distress or hypoxia, not improvement in fluid volume status. A decrease in capillary refill time (Choice D) may indicate improved peripheral perfusion but is not a direct indicator of fluid replacement success.
5. When preparing to apply dressing to a stage 2 pressure injury, which type of dressing should the nurse use?
- A. Hydrocolloid
- B. Gauze
- C. Transparent film
- D. Alginate
Correct answer: A
Rationale: The correct answer is A: Hydrocolloid. Hydrocolloid dressings are recommended for stage 2 pressure injuries as they help maintain a moist wound environment, which supports the healing process. Gauze (choice B) is not ideal for stage 2 pressure injuries as it can stick to the wound bed and disrupt the healing process. Transparent film dressings (choice C) are more suitable for superficial wounds or as a secondary dressing. Alginate dressings (choice D) are typically used for wounds with heavy exudate, which is not typically seen in stage 2 pressure injuries.
