HESI LPN
HESI Fundamental Practice Exam
1. The nurse is teaching the parents of a child who has head lice (pediculosis capitis). Which information will the nurse include in the teaching session?
- A. Treatment involves using regular shampoo.
- B. Products containing lindane are not recommended.
- C. Head lice may spread to furniture and other people.
- D. Manual removal is essential in treatment.
Correct answer: C
Rationale: The correct answer is C. Head lice are highly contagious and can spread to furniture and other people if not treated promptly. Informing the parents about the potential spread of head lice emphasizes the importance of thorough treatment and prevention measures. Choice A is incorrect as regular shampoo is not typically effective in treating head lice. Choice B is incorrect as products containing lindane are not recommended due to safety concerns. Choice D is incorrect as manual removal, though labor-intensive, is a crucial step in effectively treating head lice infestations, but it is not the most pertinent information to include in the teaching session.
2. An 18-year-old client is admitted to the intensive care unit from the emergency room following a diving accident. The injury is suspected to be at the level of the 2nd cervical vertebra. The nurse's priority assessment should be
- A. Response to stimuli
- B. Bladder control
- C. Respiratory function
- D. Muscle strength
Correct answer: C
Rationale: Injuries at the level of the 2nd cervical vertebra can affect the phrenic nerve, leading to potential impairment of respiratory function. Assessing respiratory function is crucial as compromised breathing can quickly escalate to life-threatening situations. While response to stimuli is important, ensuring adequate oxygenation takes precedence due to the immediate threat to life. Bladder control may be affected by spinal cord injuries at higher levels, but it is not the priority in this scenario. Muscle strength is a potential consequence of cervical spinal cord injury, but assessing respiratory function is more critical in the acute phase.
3. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
4. A nurse is caring for a group of clients. How should the nurse prevent the spread of infection?
- A. Place a client with TB in a negative pressure room.
- B. Use standard precautions only.
- C. Place a client with TB in a private room.
- D. Use barrier precautions only.
Correct answer: A
Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.
5. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: A
Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.
