HESI LPN
Practice HESI Fundamentals Exam
1. A client with diabetes mellitus is being taught by a nurse about mixing regular and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should roll the NPH vial between my hands before drawing it up.
- B. I should draw up the NPH insulin before the regular insulin.
- C. I should inject air into the vial of regular insulin first.
- D. I should wait 10 minutes after mixing the insulin to inject it.
Correct answer: A
Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.
2. 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.
3. What intervention should be implemented by the LPN to reduce the risk of aspiration in a client with a nasogastric tube receiving continuous enteral feedings?
- A. Elevate the head of the bed to 30-45 degrees.
- B. Check residual volumes every 4 hours.
- C. Verify tube placement every shift.
- D. Flush the tube with water every 4 hours.
Correct answer: A
Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.
4. A client is scheduled to have his alanine aminotransferase (ALT) level checked. The client asks the nurse to explain the laboratory test. Which of the following is an appropriate response by the nurse?
- A. “This test will indicate if you are at risk for developing blood clots.â€
- B. “This test will determine if your heart is performing properly.â€
- C. “This test will provide information about the function of your liver.â€
- D. “This test is used to check how your kidneys are working.â€
Correct answer: C
Rationale: The correct answer is C: “This test will provide information about the function of your liver.†Alanine aminotransferase (ALT) is an enzyme mainly found in the liver. An elevated ALT level may indicate liver damage or disease. Choices A, B, and D are incorrect because ALT is specifically related to liver function and not indicative of blood clot risk, heart performance, or kidney function.
5. A client with Guillain-Barre syndrome is in a non-responsive state, yet vital signs are stable and breathing is independent. What should the nurse document to most accurately describe the client's condition?
- A. Comatose, breathing unlabored
- B. Glasgow Coma Scale 8, respirations regular
- C. Appears to be sleeping, vital signs stable
- D. Glasgow Coma Scale 13, no ventilator required
Correct answer: B
Rationale: The correct answer is B: 'Glasgow Coma Scale 8, respirations regular.' A Glasgow Coma Scale of 8 with regular respirations accurately describes a non-responsive state with independent breathing. Choice A is incorrect because 'comatose' implies a deep state of unconsciousness, which may not be accurate in this case. Choice C is incorrect as stating the client 'appears to be sleeping' may not accurately reflect the severity of the situation. Choice D is incorrect because a Glasgow Coma Scale of 13 would not typically correspond to a non-responsive state.
