HESI Fundamental Practice Exam
1. At a mobile screening clinic, a nurse is assessing a client who reports a history of a heart murmur due to aortic stenosis. To auscultate the aortic valve, where should the nurse place the stethoscope?
- A. Second intercostal space to the right of the sternum
- B. Fifth intercostal space to the left of the sternum
- C. Third intercostal space to the left of the sternum
- D. Fourth intercostal space at the midclavicular line
Correct answer: A
Rationale: The correct location to auscultate the aortic valve is the second intercostal space to the right of the sternum. This area corresponds to the aortic valve area where aortic valve sounds are best heard. Choices B, C, and D are incorrect for auscultating the aortic valve. The fifth intercostal space to the left of the sternum is where the mitral valve is best heard, the third intercostal space to the left of the sternum is where the pulmonic valve is best heard, and the fourth intercostal space at the midclavicular line is where the tricuspid valve is best auscultated.
2. A client reports insomnia. Which of the following actions should the nurse perform shortly before bedtime?
- A. Provide a late supper
- B. Offer a wet washcloth for the client to wash their face
- C. Perform range of motion exercises
- D. Prepare a hot cocoa or tea for the client
Correct answer: B
Rationale: Offering a wet washcloth for the client to wash their face is a soothing and calming activity that can help the client relax before bedtime, promoting better sleep. Providing a late supper can lead to indigestion and disrupt sleep. Performing range of motion exercises may increase alertness rather than promoting relaxation. Preparing a hot cocoa or tea containing caffeine close to bedtime can interfere with falling asleep.
3. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
- A. Inhibits pepsin production
- B. Stimulates hydrochloric acid production
- C. Delays stomach emptying time
- D. Reduces hydrochloric acid production
Correct answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
4. During a mass casualty event, a nurse is caring for multiple clients. Which of the following clients is the nurse’s priority?
- A. A client who received crush injuries to the chest and abdomen and is expected to die.
- B. A client who has a 4-inch laceration to the head.
- C. A client who has partial-thickness and full-thickness burns to his face, neck, and chest.
- D. A client who has a fractured fibula and tibia.
Correct answer: C
Rationale: During a mass casualty event, the priority client for the nurse is the one with partial-thickness and full-thickness burns to the face, neck, and chest. Clients with severe burns in critical areas require immediate attention due to the potential for life-threatening complications such as airway compromise, fluid loss, and infection. Crush injuries and fractures, although serious, are generally less urgent in comparison and can be managed after addressing the burns. Therefore, the client with burns to the face, neck, and chest should be the nurse's priority over the other clients described.
5. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?
- A. 400 mg
- B. 200 mg
- C. 1600 mg
- D. 100 mg
Correct answer: A
Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
