HESI LPN
HESI Practice Test for Fundamentals
1. A client with chronic kidney disease has been prescribed a low-protein diet. Which food should the healthcare provider advise the client to limit?
- A. Chicken breast
- B. Apple
- C. Rice
- D. Banana
Correct answer: A
Rationale: The correct answer is A: Chicken breast. In chronic kidney disease, a low-protein diet is often recommended to reduce the workload on the kidneys. Chicken breast is a high-protein food that should be limited in such diets to help manage the progression of kidney disease. Choices B, C, and D are low in protein and are generally suitable for individuals following a low-protein diet. Apples, rice, and bananas can be included in moderation as part of a balanced diet for individuals with chronic kidney disease.
2. Which of the following statements is true of Down’s syndrome?
- A. Down’s syndrome is usually caused by an extra copy of chromosome 21 in an individual.
- B. The symptoms of Down’s syndrome are similar to those of sickle-cell anemia.
- C. Down’s syndrome is caused by a sexually transmitted infection (STI) during conception.
- D. The probability of having a child with Down’s syndrome increases with the age of the parents.
Correct answer: D
Rationale: The correct answer is D. The likelihood of having a child with Down’s syndrome increases as the age of the parents increases, particularly the mother's age. Choice A is incorrect because Down’s syndrome is caused by an extra copy of chromosome 21, not a defect in the sex chromosomes. Choice B is incorrect as the symptoms of Down’s syndrome and sickle-cell anemia are different. Choice C is also incorrect as Down’s syndrome is not caused by a sexually transmitted infection during conception.
3. Which diet selection by a client who is depressed and taking the MAO inhibitor tranylcypromine sulfate (Parnate) indicates to the nurse that the client understands the dietary restrictions imposed by this medication regimen?
- A. Hamburger, French fries, and chocolate milkshake.
- B. Liver and onions, broccoli, and decaffeinated coffee.
- C. Pepperoni and cheese pizza, tossed salad, and a soft drink.
- D. Roast beef, baked potato with butter, and iced tea.
Correct answer: D
Rationale: Roast beef, baked potato with butter, and iced tea are safe choices as they do not contain tyramine, which must be avoided with MAO inhibitors like Parnate. Tyramine-rich foods like aged cheeses, certain meats, and fermented products can cause a hypertensive crisis when combined with MAO inhibitors. Choices A, B, and C contain foods high in tyramine and are not recommended for individuals taking MAO inhibitors.
4. 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.)
- A. 0.3 mL
- B. 0.25 mL
- C. 0.4 mL
- D. 0.5 mL
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.
5. Which task could the PN safely delegate to the UAP?
- A. Oral feeding of a two-year-old child after application of a hip spica cast
- B. Assessment of the placement and patency of a NG tube
- C. Participation in staff rounds to record notes regarding client goals
- D. Evaluation of a client's incisional pain following narcotic administration
Correct answer: A
Rationale: The correct answer is A because oral feeding of a child is a task that can be safely delegated to an unlicensed assistive personnel (UAP). This task involves providing basic care and does not require specialized nursing skills. Choices B, C, and D involve assessments, recording client goals, and evaluating pain, respectively, which all require specialized nursing knowledge, judgment, and skills. These tasks are not within the scope of practice for a UAP.
