HESI LPN
HESI Fundamental Practice Exam
1. A client has been tentatively diagnosed with Graves' disease (hyperthyroidism). Which of these findings noted on the initial nursing assessment requires quick intervention by the nurse?
- A. A report of 10 pounds weight loss in the last month
- B. A comment by the client 'I just can't sit still.'
- C. The appearance of eyeballs that appear to 'pop' out of the client's eye sockets
- D. A report of the sudden onset of irritability in the past 2 weeks
Correct answer: C
Rationale: The appearance of eyeballs that appear to 'pop' out of the client's eye sockets, known as exophthalmos, requires quick intervention as it is a severe symptom of Graves' disease. Exophthalmos can indicate an acute condition and may lead to serious complications such as optic nerve damage or corneal ulceration. Weight loss, restlessness, and irritability are common manifestations of hyperthyroidism but do not pose immediate risks compared to the ocular complications associated with exophthalmos.
2. A nurse is admitting a client who has an abdominal wound with a large amount of purulent drainage. Which of the following types of transmission precautions should the nurse initiate?
- A. Protective environment
- B. Airborne precautions
- C. Droplet precautions
- D. Contact precautions
Correct answer: D
Rationale: The correct answer is D: Contact precautions. When a client has an abdominal wound with purulent drainage, contact precautions are necessary to prevent the spread of infection through direct contact. Protective environment precautions are used for immunocompromised clients, airborne precautions are for diseases transmitted by airborne particles, and droplet precautions are for diseases transmitted by respiratory droplets. In this case, the focus is on preventing direct contact transmission, making contact precautions the most appropriate choice. Protective environment, airborne, and droplet precautions are not indicated in this scenario because the primary concern is the direct contact transmission of pathogens through the wound drainage.
3. What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquids, and gases
- B. Excessive peristaltic movement
- C. Absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct answer: C
Rationale: The correct answer is C: Absence of parasympathetic ganglion cells in a portion of the colon. Hirschsprung disease is a congenital condition characterized by the absence of nerve cells (ganglia) in parts of the colon. This absence leads to a lack of peristalsis in the affected segment, resulting in severe constipation and bowel obstruction. Choices A, B, and D are incorrect. Choice A describes symptoms of diarrhea rather than a causative factor of Hirschsprung disease. Excessive peristaltic movement (choice B) is not a causative factor but rather the opposite, as Hirschsprung disease is associated with reduced peristalsis. Choice D, which refers to intussusception, is a different condition unrelated to Hirschsprung disease.
4. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?
- A. 16 ml/hour.
- B. 18 ml/hour.
- C. 20 ml/hour.
- D. 22 ml/hour.
Correct answer: C
Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.
5. A male client with delirium becomes disoriented and confused in his room at night. The best initial nursing intervention is to:
- A. Move the client next to the nurse's station
- B. Use an indirect light source and turn off the television
- C. Keep the television and a soft light on during the night
- D. Play soft music during the night, and maintain a well-lit room
Correct answer: B
Rationale: The best initial nursing intervention for a male client with delirium who becomes disoriented and confused in his room at night is to use an indirect light source and turn off the television. This approach helps to reduce stimulation and confusion, aiding in the client's orientation and comfort. Moving the client next to the nurse's station (Choice A) may not address the root cause of disorientation and could disrupt the client's routine. Keeping the television and a soft light on (Choice C) may further contribute to the client's confusion. Playing soft music and maintaining a well-lit room (Choice D) may not be as effective in reducing stimulation and promoting orientation as using an indirect light source and turning off the television.
