HESI LPN
HESI Practice Test for Fundamentals
1. A client is scheduled for hip surgery in an hour. Which of the following actions is the nurse’s priority?
- A. Ensure that the client signs the consent form.
- B. Lock the client’s valuables in a secure location.
- C. Verify the client’s lab values in the medical record.
- D. Administer the prescribed preoperative sedative.
Correct answer: A
Rationale: The nurse’s priority is to ensure that the client signs the consent form before the hip surgery. This is crucial as it ensures that the client has provided informed consent for the procedure. Locking valuables, verifying lab values, and administering sedatives are important tasks but ensuring consent takes precedence as it directly impacts the client’s right to make decisions about their care.
2. What does a positive correlation between two variables indicate?
- A. One variable causes the other.
- B. Both variables move in the same direction.
- C. Both variables move in opposite directions.
- D. There is no relationship between the variables.
Correct answer: B
Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.
3. A client with a new diagnosis of diabetes mellitus is being taught how to administer insulin. Which of the following instructions should the nurse include?
- A. Administer the insulin in the same body area each time.
- B. Store the insulin according to the manufacturer's instructions.
- C. Rotate injection sites within the same body area.
- D. Inject the insulin at a 45-degree angle.
Correct answer: C
Rationale: The correct instruction the nurse should include is to rotate injection sites within the same body area. This practice helps prevent lipodystrophy, a condition characterized by the thickening or thinning of subcutaneous fat at the injection sites, which can affect insulin absorption. Choice A is incorrect because administering insulin in the same area each time can lead to lipodystrophy. Choice B is incorrect as insulin should be stored according to the manufacturer's instructions, which may include refrigeration. Choice D is incorrect because the angle of insulin injection (usually 90 degrees) is determined by the length of the needle and the amount of subcutaneous fat, not a fixed 45-degree angle.
4. What is the expected date of delivery for a woman whose last menstrual period was on April 20th?
- A. January 20th
- B. January 27th
- C. January 29th
- D. January 31st
Correct answer: B
Rationale: The expected date of delivery is calculated by adding 9 months and 7 days to the last menstrual period. For April 20th, the expected date is January 27th. Therefore, the correct answer is B. Choice A, January 20th, is incorrect as it does not account for the additional 7 days. Choice C, January 29th, and Choice D, January 31st, are also incorrect as they do not consider the standard calculation method for estimating the due date.
5. The healthcare provider is teaching a patient about contact lens care. Which instructions will the healthcare provider include in the teaching session?
- A. Use tap water to clean soft lenses.
- B. Wash and rinse the lens storage case daily.
- C. Reuse storage solution for no longer than a week.
- D. Keep the lenses in a cool, dry place when not in use.
Correct answer: B
Rationale: The correct answer is B. Washing and rinsing the lens storage case daily is essential to prevent contamination and infections. Choice A is incorrect as tap water should not be used to clean soft lenses due to the risk of introducing harmful microorganisms. Choice C is incorrect as the storage solution should not be reused for longer than recommended to maintain its effectiveness and prevent eye infections. Choice D is incorrect because lenses should be stored in a clean, disinfected case, not just in a cool, dry place, to avoid contamination.
