HESI Fundamentals Study Guide
1. To use proper body mechanics while making an occupied bed for a client on bed rest, the nurse should:
- A. Place the bed in a high horizontal position
- B. Use a low bed position
- C. Bend at the waist
- D. Keep the bed flat and at a comfortable working height
Correct answer: A
Rationale: When making an occupied bed for a client on bed rest, the nurse should place the bed in a high horizontal position to promote better body mechanics. This positioning helps reduce strain on the nurse's back and promotes proper alignment while working. Using a low bed position can lead to awkward bending and increased risk of musculoskeletal injuries. Bending at the waist is discouraged as it can strain the back. Keeping the bed flat and at a comfortable working height may not provide the optimal ergonomic setup needed to prevent injury.
2. What action should be taken to maintain the patency of a peripherally inserted central catheter (PICC)?
- A. Flush the catheter with heparin solution daily.
- B. Change the dressing at the insertion site daily.
- C. Use sterile technique when changing the dressing.
- D. Keep the insertion site dry at all times.
Correct answer: C
Rationale: The correct answer is to use sterile technique when changing the dressing. This practice is essential for preventing infections that can compromise the patency of the PICC line. While flushing the catheter with heparin solution helps prevent clot formation, it does not directly maintain patency. Changing the dressing daily is important for hygiene but does not have a direct impact on catheter patency. Keeping the insertion site dry is crucial to prevent infections but does not specifically address patency maintenance.
3. An 86-year-old female client with Alzheimer's disease is wandering the busy halls of the extended care facility and asks the nurse, "Where should I stand for the parade?" Which response is best for the LPN/LVN to provide?
- A. Anywhere you want to stand as long as you do not get hurt by those in the parade.
- B. You are confused because of all the activity in the hall. There is no parade.
- C. Let us go back to the activity room and see what is going on in there.
- D. Remember I told you that this is a nursing home and I am your nurse.
Correct answer: C
Rationale: Redirecting the client to a less confusing environment can help reduce anxiety and reorient her to reality.
4. After a motor vehicle collision, a client is admitted to the medical unit with acute adrenal insufficiency (Addisonian crisis). Which prescription should the nurse implement?
- A. Determine serum glucose levels
- B. Withhold potassium additives to IV fluids
- C. Give IV corticosteroid replacement
- D. Prepare to initiate IV vasopressors
Correct answer: C
Rationale: In a client with acute adrenal insufficiency (Addisonian crisis) following a motor vehicle collision, the priority intervention is to administer IV corticosteroid replacement. This is crucial to manage the crisis by replacing the deficient cortisol. Determining serum glucose levels (Choice A) may be important but is not the immediate priority in this situation. Withholding potassium additives to IV fluids (Choice B) is not indicated and may exacerbate electrolyte imbalances. Initiating IV vasopressors (Choice D) is not the primary treatment for acute adrenal insufficiency and should be reserved for managing hypotension that is unresponsive to corticosteroid therapy.
5. When evaluating the laboratory report of a 1-year-old infant’s hematocrit, a healthcare professional compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?
- A. 19% to 32%
- B. 29% to 41%
- C. 37% to 47%
- D. 42% to 69%
Correct answer: C
Rationale: The correct answer is C: 37% to 47%. The normal hematocrit range for a 12-month-old infant is between 37% to 47%, which reflects the expected blood volume and red blood cell levels for this age. Choice A (19% to 32%) and Choice B (29% to 41%) are too low and do not encompass the typical hematocrit range for a healthy 1-year-old. Choice D (42% to 69%) is too high and falls outside the usual hematocrit values for this age group.
