HESI Fundamentals
1. A client is admitted with a stage four pressure ulcer that has a black, hardened surface and a light-pink wound bed with malodorous green drainage. Which dressing is best for the nurse to use first?
- A. Hydrogel dressing.
- B. Exudate absorber.
- C. Wet-to-moist dressing.
- D. Transparent adhesive film.
Correct answer: C
Rationale: The best initial dressing for a stage four pressure ulcer with necrotic tissue is a wet-to-moist dressing. This dressing helps to provide moisture, soften necrotic tissue, and prepare the wound bed for healing. It promotes autolytic debridement and can help manage malodorous drainage. Once the necrotic tissue is loosened, other advanced dressings like hydrogel or alginate may be used in the wound bed to facilitate healing.
2. A female client reports that she drank a liter of a solution to cleanse her intestines but vomited immediately after. How many ml of fluid intake should the nurse document?
- A. 1000 ml
- B. 800 ml
- C. 760 ml
- D. 500 ml
Correct answer: C
Rationale: The correct answer is 760 ml. One liter equals 1000 ml. As the client vomited immediately after drinking, she would have expelled approximately 240 ml (1 cup). Subtracting this from the initial intake of 1000 ml gives us 760 ml as the remaining fluid intake that should be documented. Choices A, B, and D are incorrect because they do not reflect the correct calculation of subtracting the amount vomited from the initial intake.
3. A client has a prescription to take guaifenesin (Humibid) every 4 hours, as needed. The nurse determines that the client understands the most effective use of this medication if the client states that he or she will:
- A. Watch for irritability as a side effect.
- B. Take the tablet with a full glass of water.
- C. Take an extra dose if the cough is accompanied by fever.
- D. Crush the sustained-release tablet if immediate relief is needed.
Correct answer: B
Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.
4. What do prokaryotic cells lack in comparison to eukaryotic cells?
- A. A defined nucleus and a series of membrane-bound organelles
- B. A defined nucleus and no membrane-bound organelles
- C. No defined nucleus and a series of membrane-bound organelles
- D. No defined nucleus and no membrane-bound organelles
Correct answer: D
Rationale: Prokaryotic cells are characterized by the absence of a defined nucleus and membrane-bound organelles. Choice A is incorrect because prokaryotic cells lack membrane-bound organelles. Choice B is incorrect because prokaryotic cells lack both a defined nucleus and membrane-bound organelles. Choice C is incorrect as prokaryotic cells have no defined nucleus. Therefore, the correct answer is D.
5. The nurse is assessing a client 2 hours postoperatively after a femoral popliteal bypass. The upper leg dressing becomes saturated with blood. The nurse's first action should be to
- A. Wrap the leg with elastic bandages
- B. Apply pressure at the bleeding site
- C. Reinforce the dressing and elevate the leg
- D. Remove the dressings and re-dress the incision
Correct answer: B
Rationale: In this scenario where the upper leg dressing becomes saturated with blood post-femoral popliteal bypass, the nurse's first action should be to apply pressure at the bleeding site. Applying pressure is essential to control hemorrhage and prevent further blood loss. Choice A is incorrect as wrapping the leg with elastic bandages would not address the immediate issue of controlling the bleeding. Choice C is incorrect because reinforcing the dressing and elevating the leg should come after controlling the bleeding. Choice D is incorrect as removing the dressings and re-dressing the incision should only be done after the bleeding is under control to prevent excessive blood loss.
