HESI LPN
HESI Fundamentals Exam
1. A healthcare provider is assessing a client with a diagnosis of acute pancreatitis. Which laboratory value would be most concerning?
- A. Serum amylase of 200 U/L
- B. Serum lipase of 250 U/L
- C. Blood glucose of 200 mg/dL
- D. Serum calcium of 7.5 mg/dL
Correct answer: D
Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.
2. A client who has a history of hyperthyroidism was initially admitted with lethargy and confusion. Which additional finding warrants the most immediate action by the nurse?
- A. Facial puffiness and periorbital edema
- B. Hematocrit of 30%
- C. Cold and dry skin
- D. Further decline in LOC
Correct answer: D
Rationale: A further decline in LOC can indicate severe complications and requires immediate attention. This change may signify worsening neurological status, which could lead to life-threatening consequences if not addressed promptly. Choices A, B, and C may also be concerning in a client with a history of hyperthyroidism, but a further decline in LOC takes priority due to its potential for rapid deterioration and the need for urgent intervention.
3. A client has an order for 1000 ml of D5W over an 8-hour period. The nurse discovers that 800 ml has been infused after 4 hours. What is the priority nursing action?
- A. Ask the client if there are any breathing problems
- B. Have the client void as much as possible
- C. Check the vital signs
- D. Auscultate the lungs
Correct answer: D
Rationale: The correct answer is D: Auscultate the lungs. When a significant amount of fluid has been infused, especially in a short period, it is crucial to assess for signs of fluid overload or pulmonary complications, such as crackles or decreased breath sounds. This can be achieved by auscultating the lungs. Choice A, asking the client about breathing problems, may provide valuable information, but direct assessment through auscultation takes priority. Choice B, having the client void, and Choice C, checking vital signs, are important nursing actions but are not as urgent as assessing the lungs for potential complications in this scenario.
4. Which nutrient is classified as a micronutrient?
- A. minerals
- B. proteins
- C. alcohols
- D. carbohydrates
Correct answer: A
Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.
5. While caring for a client who, while sitting in a chair, starts to experience a seizure, what action should the nurse take?
- A. Lower the client to the floor and place a pad under the client's head.
- B. Hold the client's head still to prevent injury.
- C. Restrain the client to prevent movement.
- D. Place the client in a supine position.
Correct answer: A
Rationale: During a seizure, the priority is to lower the client to the floor to prevent injury and ensure their safety. Placing a pad under the client's head helps protect the head from injury. Choice B, holding the client's head still, is incorrect as it can lead to harm; it's essential to allow movement during a seizure to prevent neck injury. Choice C, restraining the client, is dangerous and can cause harm by restricting movement. Choice D, placing the client in a supine position, is also not recommended during a seizure as it does not provide adequate protection for the client.
