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. When teaching adult cardiopulmonary resuscitation (CPR) to a group of newly licensed nurses, what should the charge nurse instruct as the initial response in CPR?
- A. Confirm unresponsiveness
- B. Check for a pulse
- C. Begin chest compressions
- D. Call for emergency help
Correct answer: A
Rationale: The correct initial response in CPR is to confirm unresponsiveness. This step is crucial to ensure that the person actually needs CPR before proceeding with further actions. Checking for unresponsiveness is essential to determine if the individual is in need of immediate assistance. Checking for a pulse or beginning chest compressions without confirming unresponsiveness could waste valuable time and potentially harm the individual. Calling for emergency help is important, but it should follow the confirmation of unresponsiveness to ensure timely activation of emergency services.
3. The nurse is assessing a 17-year-old female client with bulimia. Which of the following laboratory reports would the nurse anticipate?
- A. Increased serum glucose
- B. Decreased albumin
- C. Decreased potassium
- D. Increased sodium retention
Correct answer: C
Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.
4. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
5. A nurse is teaching the parents of a toddler about discipline. Which of the following actions should the nurse suggest?
- A. Establish consistent boundaries for the toddler.
- B. Place the toddler in a room with the door closed.
- C. Inform the toddler how you feel when he misbehaves.
- D. Use a favorite snack to reward the toddler.
Correct answer: A
Rationale: The correct answer is to establish consistent boundaries for the toddler. This approach helps toddlers understand expectations and promotes consistent behavior. Placing the toddler alone or using food rewards may not effectively teach discipline and could be inappropriate. Informing the toddler about feelings when misbehaving may not be developmentally appropriate for a toddler to understand the consequences of their actions.
