HESI LPN
HESI Practice Test for Fundamentals
1. A nurse educator is conducting a parenting class for new guardians of infants. Which of the following statements made by a participant indicated understanding?
- A. “I will set my water heater at 130°F.”
- B. “Once my baby can sit up, they should be safe in the bathtub.”
- C. “I will place my baby on their stomach to sleep.”
- D. “Once my infant starts to push up, I will remove the mobile from over the crib.”
Correct answer: D
Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130°F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.
2. A nurse is reviewing the correct use of a fire extinguisher with a client. Which of the following actions should the nurse direct the client to take first?
- A. Remove the safety pin from the extinguisher.
- B. Aim the extinguisher at the base of the fire.
- C. Squeeze the handle to release the extinguishing agent.
- D. Sweep the extinguisher from side to side.
Correct answer: A
Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.
3. A child has been diagnosed with classic hemophilia. A nurse teaches the child’s parents how to administer the plasma component factor VIII through a venous port. It is to be given 3 times a week. What should the nurse tell them about when to administer this therapy?
- A. Whenever a bleed is suspected
- B. In the morning on scheduled days
- C. At bedtime while the child is lying quietly in bed
- D. On a regular schedule at the parents’ convenience
Correct answer: B
Rationale: Administering factor VIII in the morning on scheduled days ensures that there is a consistent level of the plasma component throughout the day, especially when the child is active. This timing helps to maintain adequate levels of factor VIII to prevent bleeding episodes. Choice A is incorrect because administering factor VIII only when a bleed is suspected would not provide the consistent prophylactic coverage needed for children with hemophilia. Choice C is incorrect as bedtime administration may not be practical for ensuring the plasma component is available during the child's active hours. Choice D is incorrect because administering factor VIII on a regular schedule, rather than at specific times of the day, may not optimize its effectiveness in preventing bleeding episodes.
4. The nurse is teaching a client with diabetes about foot care. Which instruction is most important to prevent complications?
- A. Soak feet in warm water daily
- B. Apply moisturizer between the toes
- C. Wear cotton socks
- D. Inspect feet daily for cuts or sores
Correct answer: D
Rationale: The correct answer is D: Inspect feet daily for cuts or sores. Daily foot inspection is crucial for clients with diabetes to detect early signs of injury or infection. Soaking feet in warm water daily (choice A) can lead to skin maceration, making the skin more susceptible to breakdown. Applying moisturizer between the toes (choice B) can increase moisture and the risk of fungal infections. While wearing cotton socks (choice C) is beneficial for diabetic foot care, it is not as crucial as daily foot inspections to prevent complications.
5. Before a client undergoes a Magnetic Resonance Imaging (MRI) scan with contrast, what should the nurse assess?
- A. If the client has any metal implants
- B. If the client has allergies to iodine or shellfish
- C. If the client has a history of claustrophobia
- D. If the client has ever had a similar procedure before
Correct answer: A
Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (Choice B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (Choice C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (Choice D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.
