HESI LPN
Practice HESI Fundamentals Exam
1. A client requires a 24-hour urine collection. Which statement by the client indicates an understanding of the teaching?
- A. "I had a bowel movement, but I was able to save the urine."
- B. "I have a specimen in the bathroom from about 30 minutes ago."
- C. "I flushed what I urinated at 7 a.m. and have saved all urine since."
- D. "I drink a lot, so I will fill up the bottle and complete the test quickly."
Correct answer: C
Rationale: The correct answer is C because for a 24-hour urine collection, the first void is discarded, and all subsequent urine should be saved. Choice A is incorrect because bowel movements do not contribute to a urine collection. Choice B indicates a single specimen rather than continuous collection over 24 hours. Choice D is incorrect as it incorrectly suggests rushing the test by drinking excessively.
2. During auscultation of a client experiencing chest pain worsened by inspiration, a nurse hears a high-pitched scratching sound in both systole and diastole with the diaphragm of the stethoscope placed at the left sternal border. Which of the following heart sounds should the nurse document?
- A. Pericardial friction rub
- B. Murmur
- C. S1 and S2
- D. Bruit
Correct answer: A
Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.
3. A client with a history of coronary artery disease is experiencing chest pain. What is the priority action for the LPN/LVN to take?
- A. Administer nitroglycerin sublingually.
- B. Obtain a 12-lead ECG.
- C. Measure the client's vital signs.
- D. Administer oxygen via nasal cannula.
Correct answer: A
Rationale: The correct answer is to administer nitroglycerin sublingually. Administering nitroglycerin sublingually is the priority action for a client with chest pain and a history of coronary artery disease. Nitroglycerin helps dilate the coronary arteries, improving blood flow to the heart muscle and providing rapid relief of chest pain. Obtaining a 12-lead ECG, measuring vital signs, and administering oxygen are important actions but should follow the administration of nitroglycerin in the management of chest pain in a client with coronary artery disease.
4. The nurse is caring for a client with a pressure ulcer on the sacrum. Which action should the LPN/LVN take to prevent further skin breakdown?
- A. Apply a hydrocolloid dressing to the ulcer.
- B. Reposition the client every 2 hours.
- C. Use a donut-shaped cushion when the client is sitting.
- D. Massage the area around the ulcer to promote circulation.
Correct answer: B
Rationale: Repositioning the client every 2 hours is the most appropriate action to prevent further skin breakdown in a client with a pressure ulcer on the sacrum. This practice helps relieve pressure on the affected area, promoting circulation and reducing the risk of tissue damage. Applying a hydrocolloid dressing (Choice A) may be beneficial for wound healing but is not the initial preventive measure. Using a donut-shaped cushion (Choice C) can actually increase pressure on the sacrum and worsen the condition. Massaging the area around the ulcer (Choice D) can further damage delicate skin and tissues, leading to more harm instead of prevention.
5. While assessing an 18-month-old child, a nurse observes that the toddler can crawl upstairs but needs assistance when climbing the stairs upright. What does this action indicate to the nurse?
- A. Presence of talipes equinovarus
- B. Reflective of neurologic damage
- C. Expected behavior in a toddler of this age
- D. Existence of developmental dysplasia of the hip
Correct answer: C
Rationale: At 18 months of age, needing assistance to climb stairs upright is considered normal behavior for a toddler. Crawling upstairs is a different motor skill and does not necessarily correlate with the ability to climb stairs. The child is still developing gross motor skills, and climbing stairs upright typically requires more coordination and strength, which may not be fully developed at this age. Choices A, B, and D are not relevant in this scenario as the observed behavior is within the expected range of development for an 18-month-old child.
