HESI LPN
HESI Fundamental Practice Exam
1. A client with pneumonia has a decrease in oxygen saturation from 94% to 88% while ambulating. Based on these findings, which intervention should the LPN/LVN implement first?
- A. Assist the ambulating client back to the bed.
- B. Encourage the client to ambulate to resolve pneumonia.
- C. Obtain a prescription for portable oxygen while ambulating.
- D. Move the oximetry probe from the finger to the earlobe.
Correct answer: A
Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.
2. When providing hygiene for an older-adult patient, why does the nurse closely assess the skin?
- A. Outer skin layer becomes less resilient.
- B. Less frequent bathing may be required.
- C. Skin becomes more subject to bruising.
- D. Sweat glands become less active.
Correct answer: B
Rationale: The correct answer is B: 'Less frequent bathing may be required.' In older adults, daily bathing or using hot water and harsh soap can lead to excessively dry skin. Therefore, the nurse closely assesses the skin to determine if less frequent bathing is necessary to prevent skin dryness and maintain skin integrity. Choice A is incorrect because the outer skin layer does not become less resilient with age. Choice C is incorrect as aging skin is actually more prone to bruising due to thinning of the skin. Choice D is incorrect because sweat gland activity generally decreases with age, leading to reduced skin moisture rather than increased activity.
3. During a follow-up visit, a home health nurse notices that a client with a gastrostomy tube, who receives intermittent feedings and medications, has developed diarrhea. Which of the following findings should the nurse identify as a possible cause of the diarrhea?
- A. The client’s caregiver washes out the feeding bag once every 24 hours with warm water.
- B. The client’s caregiver washes out the feeding bag with hot water every 24 hours.
- C. The client’s caregiver changes the feeding bag every 48 hours.
- D. The client’s caregiver adds water to the formula before administration.
Correct answer: A
Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
4. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What is the best initial action for the LPN/LVN to take?
- A. Administer glucagon intramuscularly.
- B. Give the client 4 ounces of orange juice.
- C. Give the client a snack containing protein and carbohydrates.
- D. Encourage the client to rest until symptoms resolve.
Correct answer: B
Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.
5. When replacing a client's surgical dressing, what should the nurse do?
- A. Don sterile gloves to remove the old dressing
- B. Wash hands thoroughly before removing the old dressing
- C. Use sterile gloves to remove the old dressing
- D. Apply a new dressing before removing the old one
Correct answer: C
Rationale: When replacing a client's surgical dressing, the nurse should use sterile gloves to remove the old dressing. Sterile technique is essential to prevent introducing infection to the wound. Choice A is incorrect because clean gloves are not sufficient; sterile gloves are necessary to maintain asepsis. Choice B, washing hands, is an important step before and after the procedure to maintain hand hygiene, but sterile gloves are required during the dressing change. Choice D is incorrect because a new dressing should only be applied after the old one has been removed to prevent contamination and ensure proper wound care.
