HESI Fundamental Practice Exam
1. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?
- A. Monitor the client's respiratory rate
- B. Check the client's urine output
- C. Administer the potassium chloride as a rapid IV push
- D. Dilute the potassium chloride in an appropriate IV solution
Correct answer: D
Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.
2. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?
- A. Assess the client's respiratory rate and effort.
- B. Measure the client's oxygen saturation level.
- C. Monitor the client's arterial blood gas levels.
- D. Check the client's blood pressure.
Correct answer: B
Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.
3. A nurse manager is preparing to review medication documentation with a group of newly licensed nurses. Which of the following statements should the nurse manager plan to include in the teaching?
- A. Use the complete name of the medication magnesium sulfate.
- B. Delete the space between the numerical dose and the unit of measure.
- C. Write the letter U when noting the dosage of insulin.
- D. Use the abbreviation SC when indicating an injection.
Correct answer: A
Rationale: The correct answer is to use the complete name of the medication magnesium sulfate. This is important to prevent confusion with morphine sulfate, which is abbreviated as MSO4. Choice B is incorrect as it is essential to maintain a space between the numerical dose and the unit of measure for clarity in medication documentation. Choice C is incorrect as the standard abbreviation for units is 'U' for international units, not for the dosage of insulin. Choice D is incorrect as the appropriate abbreviation for subcutaneous injection is 'SC,' not just 'SC.' Therefore, the nurse manager should emphasize using the full name of medications to avoid errors and ensure patient safety.
4. A client has a terminal diagnosis and their health is declining. The client requests information about advance directives. Which of the following responses should the nurse make?
- A. Offering to discuss advance directives and provide brochures respects the client's request and provides information.
- B. Informing the client that advance directives are not necessary at this time is incorrect as they play a crucial role in end-of-life care.
- C. Scheduling a meeting with the family to discuss advance directives is not the most appropriate response as the client directly requested information.
- D. Directing the client to ask their provider about advance directives does not directly address the client's request for information.
Correct answer: A
Rationale: When a client with a terminal illness asks about advance directives, it is essential to provide the information they seek. Choice A is the correct response as it acknowledges the client's request and offers to discuss advance directives while providing additional resources in the form of brochures. This approach empowers the client to make informed decisions about their end-of-life care. Choices B, C, and D are incorrect because they do not directly address the client's request or provide the information the client is seeking. Choice B dismisses the importance of advance directives, which are crucial in end-of-life care planning. Choice C involves the family unnecessarily when the client directly requested information. Choice D deflects the responsibility back to the client to seek information from their provider instead of addressing their immediate request.
5. A client with a history of alcoholism is admitted with confusion and ataxia. The LPN/LVN recognizes that these symptoms may be related to a deficiency in which vitamin?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin B1 (Thiamine)
Correct answer: D
Rationale: The correct answer is Vitamin B1 (Thiamine). Vitamin B1 deficiency, also known as Thiamine deficiency, is common in clients with a history of alcoholism. Thiamine is essential for proper brain function, and its deficiency can lead to neurological symptoms such as confusion and ataxia. Vitamin A, C, and D deficiencies do not typically present with confusion and ataxia in the context of alcoholism. Vitamin A deficiency mainly affects vision, Vitamin C deficiency leads to scurvy with symptoms like bleeding gums, and Vitamin D deficiency is associated with bone disorders. Therefore, they are not the correct choices in this scenario.
