HESI Fundamentals Exam Questions
Question 1 of 5
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?
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.
Question 2 of 5
A nurse is preparing to administer methylprednisolone 10 mg by IV bolus. The amount available is methylprednisolone injection 40-mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Do not use a trailing zero.)
Correct Answer: A
Rationale: To calculate the mL to administer, use the formula: Dose required (mg) · Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg · 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.
Question 3 of 5
A nurse in an outpatient surgical center is admitting a client for a laparoscopic procedure. The client has a prescription for preoperative diazepam. Prior to administering the medication, which of the following actions is the nurse's priority?
Correct Answer: C
Rationale: The correct answer is C: Identifying the client's medication allergies. This is the priority action before administering any medication to prevent allergic reactions or adverse effects. Teaching the client about the medication's purpose is important for client understanding but not as critical as ensuring the absence of allergies. While giving medication at the prescribed time is crucial, verifying allergies takes precedence to ensure patient safety. Documenting the client's anxiety level is relevant for holistic care but is not the priority compared to ensuring safe medication administration.
Question 4 of 5
A client is being taught about medications at discharge. Which statement should the nurse identify as an indication that the client understands the instructions?
Correct Answer: B
Rationale: The correct answer is B. Adding liquid medication to pudding can help with swallowing difficulties, demonstrating understanding of the instructions. Options A and C are incorrect as altering time-release capsules and enteric-coated pills is not recommended in medication administration. Option A is incorrect as time-release capsules should not be opened and sprinkled on food, affecting their efficacy. Option C is incorrect as crushing enteric-coated pills can affect their absorption. Option D is unrelated to medication administration and does not demonstrate understanding of the instructions.
Question 5 of 5
A client with amphetamine toxicity and sensory overload is being cared for by a nurse. Which intervention should the nurse implement?
Correct Answer: C
Rationale: The most appropriate intervention for a client with amphetamine toxicity and sensory overload is to provide a private room and limit stimulation. This approach helps reduce external stimuli, which can exacerbate sensory overload, and creates a calming environment for the client. Encouraging visitors to distract the client may worsen sensory overload by adding more stimulation. Speaking softly, rather than at a higher volume, is more suitable to help maintain a calm environment. Therefore, the correct choice is to provide a private room and limit stimulation (option C) in this scenario.
