HESI Fundamentals Practice Test
1. The healthcare provider plans to administer diazepam, 4 mg IV push, to a client with severe anxiety. How many milliliters should the healthcare provider administer? (Round to the nearest tenth.)
- A. 0.2 mL
- B. 0.8 mL
- C. 1.25 mL
- D. 2.0 mL
Correct answer: B
Rationale: To calculate the volume to administer, use the formula (1 mL × 4 mg) / 5 mg = 0.8 mL. The healthcare provider should administer 0.8 mL of diazepam for a dosage of 4 mg IV push. Choice A is incorrect because it results from an incorrect calculation. Choices C and D are incorrect as they do not align with the correct calculation based on the provided dosage.
2. The client is being instructed on the proper use of a metered-dose inhaler. Which instruction should be provided to ensure the optimal benefits from the drug?
- A. Fill your lungs with air through your mouth and then compress the inhaler.
- B. Compress the inhaler while slowly breathing in through your mouth.
- C. Compress the inhaler while inhaling quickly through your nose.
- D. Exhale completely after compressing the inhaler and then inhale.
Correct answer: B
Rationale: The correct technique for using a metered-dose inhaler involves compressing the inhaler while slowly breathing in through the mouth. This method helps ensure that the medication reaches deep into the lungs, allowing for optimal bronchodilation effect. Inhaling quickly through the nose or filling the lungs with air before compressing the inhaler are not recommended techniques for using a metered-dose inhaler effectively.
3. A client with frequent urinary tract infections (UTIs) asks the nurse about drinking juice daily to prevent future UTIs. Which response is best for the nurse to provide?
- A. Orange juice has vitamin C, which deters bacterial growth.
- B. Apple juice is the most useful in acidifying the urine.
- C. Cranberry juice stops pathogens' adherence to the bladder.
- D. Grapefruit juice increases the absorption of most antibiotics.
Correct answer: C
Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs. Choices A, B, and D are incorrect because while vitamin C in orange juice may have some benefits, it is not specifically known for deterring bacterial growth in the urinary tract. Apple juice does not significantly impact urine acidity, and grapefruit juice does not enhance antibiotic absorption, making them less effective choices for preventing UTIs compared to cranberry juice.
4. In completing a client's preoperative routine, the nurse finds that the operative permit is not signed. The client begins to ask more questions about the surgical procedure. Which action should the nurse take next?
- A. Witness the client's signature on the permit.
- B. Answer the client's questions about the surgery.
- C. Inform the surgeon that the operative permit is not signed and the client has questions about the surgery.
- D. Reassure the client that the surgeon will answer any questions before the anesthesia is administered.
Correct answer: C
Rationale: The nurse should inform the surgeon promptly that the operative permit is not signed and the client has questions about the surgery. It is crucial for the surgeon to be aware of these issues as it is their responsibility to explain the procedure to the client and ensure that the necessary consent is obtained before proceeding with the surgery. Answering the client's questions directly (choice B) may not be appropriate as the surgeon is the one responsible for providing detailed information about the procedure. Witnessing the client's signature (choice A) is premature since the permit is not signed. Reassuring the client (choice D) is not the most appropriate action at this point; the priority is to involve the surgeon in addressing the unsigned permit and the client's questions.
5. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?
- A. Regular insulin
- B. NPH insulin
- C. Lispro insulin
- D. Glargine insulin
Correct answer: A
Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.
