HESI LPN
HESI Practice Test for Fundamentals
1. 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.
2. Seconal 0.1 gram PRN at bedtime is prescribed to a client for rest. The scored tablets are labeled 1.5 grains per tablet. How many tablets should the LPN/LVN plan to administer?
- A. 0.5 tablet
- B. 1 tablet
- C. 1.5 tablets
- D. 2 tablets
Correct answer: B
Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.
3. A client is receiving teaching from a healthcare provider about reducing the adverse effects of immobility. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will perform ankle and knee exercises every hour - Range of motion (ROM) is needed to prevent contractures.
- B. I will hold my breath when rising from a sitting position.
- C. I will remove my antiembolic stockings while I am in bed.
- D. I will have my partner help me change positions every 4 hours.
Correct answer: A
Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.
4. A client with lower extremity weakness is being taught a four-point crutch gait by a nurse. Which of the following instructions should the nurse include in the teaching?
- A. Bear weight on both legs.
- B. Move the crutches and the weak leg in unison.
- C. Advance the crutches and the strong leg simultaneously.
- D. Move the crutches forward, then move one leg at a time.
Correct answer: D
Rationale: The correct technique for a four-point crutch gait involves moving the crutches forward, then moving one leg at a time. This method provides stability and support by alternating movement between the crutches and legs. Choice A is incorrect because bearing weight on both legs simultaneously is not the correct method for a four-point gait. Choice B is incorrect as moving the crutches and weak leg together does not provide the required stability. Choice C is incorrect as advancing the crutches and strong leg together does not promote the alternating movement needed for a four-point gait.
5. When assessing a client's skin turgor, a nurse should:
- A. Grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression
- B. Check skin elasticity on the back of the hand
- C. Press on the skin over the abdomen
- D. Measure skin turgor on the lower leg
Correct answer: A
Rationale: Correct answer: When assessing a client's skin turgor, a nurse should grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression. This method is reliable for evaluating hydration status as it is less influenced by age-related skin changes or adipose tissue. Choice B, checking skin elasticity on the back of the hand, is not the preferred method for assessing skin turgor. Choice C, pressing on the skin over the abdomen, is not a standard location for assessing skin turgor. Choice D, measuring skin turgor on the lower leg, is not a recommended site for assessing skin turgor in clinical practice.
