HESI LPN
HESI Fundamental Practice Exam
1. The client is receiving discharge instructions for warfarin (Coumadin). Which statement by the client indicates a need for further teaching?
- A. I will avoid eating foods high in vitamin K.
- B. I will have my blood tested regularly to monitor my INR levels.
- C. I will take the medication at the same time every day.
- D. I will use a soft toothbrush to prevent bleeding gums.
Correct answer: A
Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.
2. A parent tells the nurse, “My 9-month-old baby no longer has the same strong grasp that was present at birth and no longer acts startled by loud noises.” How should the nurse explain these changes in behavior?
- A. “I will check these responses before deciding how to proceed.”
- B. “Failure of these responses may be related to a developmental delay.”
- C. “Additional sensory stimulation is needed to aid in the return of these responses.”
- D. “These responses are replaced by voluntary activity at about five months of age.”
Correct answer: D
Rationale: The correct answer is D: “These responses are replaced by voluntary activity at about five months of age.” The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. Choice A is incorrect because checking the responses before deciding a course of action does not address the developmental milestone related to the reflexes. Choice B is incorrect as it jumps to a conclusion of developmental delay without considering the normal developmental process. Choice C is incorrect as additional sensory stimulation is not necessary for the return of these reflexes, as they are expected to naturally diminish as part of normal development.
3. The nurse is caring for a 15-year-old boy who has sustained burn injuries. The nurse observes the burn developing a purplish color with discharge and a foul odor. The nurse suspects which infection?
- A. Burn wound cellulitis.
- B. Invasive burn cellulitis.
- C. Burn impetigo.
- D. Staphylococcal scalded skin syndrome.
Correct answer: B
Rationale: The correct answer is B: Invasive burn cellulitis. Invasive burn cellulitis presents with the burn developing a dark brown, black, or purplish color with discharge and a foul odor. Burn wound cellulitis (choice A) typically involves redness, warmth, and swelling around the burn site. Burn impetigo (choice C) is a superficial infection characterized by honey-colored crusting. Staphylococcal scalded skin syndrome (choice D) is a condition caused by exotoxins from Staphylococcus aureus, leading to widespread skin peeling.
4. The nurse documents that a male client with paranoid schizophrenia is delusional. Which statement by the client confirms this assessment?
- A. The voices are telling me to kill the next person I see.
- B. The fire is burning my skin away right now.
- C. The snakes on the wall are going to eat me.
- D. The nurse at night is trying to poison me with pills.
Correct answer: D
Rationale: The correct answer is D. Believing that the nurse is trying to poison him with pills is a clear indication of delusional paranoia, a common symptom in paranoid schizophrenia. Choices A, B, and C do not directly relate to paranoid delusions and are more indicative of hallucinations or other forms of delusions not specific to paranoia.
5. The healthcare provider is caring for a client with tuberculosis (TB). Which type of isolation precautions should the healthcare provider implement?
- A. Droplet precautions
- B. Airborne precautions
- C. Contact precautions
- D. Standard precautions
Correct answer: B
Rationale: When caring for a client with tuberculosis (TB), airborne precautions should be implemented. Tuberculosis is spread through the air via droplet nuclei, requiring the use of airborne precautions to prevent the transmission of the infection. Droplet precautions are used for diseases spread by large respiratory droplets, such as influenza or pertussis. Contact precautions are used for diseases that spread through direct contact, such as MRSA. Standard precautions are used for all clients to prevent the transmission of infections from blood, body fluids, non-intact skin, and mucous membranes.
