HESI LPN
HESI Fundamental Practice Exam
1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
2. A client is grieving the loss of her partner and expresses thoughts of not seeing the point of living anymore. What action should the nurse take?
- A. Recommend that the client seek spiritual guidance
- B. Request additional support from the client's family
- C. Tell the client that this is a normal response to grief
- D. Ask the client if she plans to harm herself
Correct answer: D
Rationale: When a client expresses feelings of hopelessness or worthlessness, it is crucial for the nurse to assess for suicidal ideation. Asking the client directly if she plans to harm herself is essential to determine the level of risk and ensure appropriate interventions are implemented. Recommending spiritual guidance (Choice A) may not address the immediate safety concerns related to suicidal ideation. Requesting additional support from the client's family (Choice B) is not as direct in addressing the client's safety. While stating that the client's response is a normal part of grief (Choice C) may provide validation, it does not address the potential risk of harm to the client.
3. A staff nurse is teaching a newly hired nurse about alternatives to the use of restraints on clients who are confused. Which of the following instructions should the nurse include?
- A. “Use full-length side rails on the client’s bed.”
- B. “Check on the client frequently while they are in the restroom.”
- C. “Encourage physical activity throughout the day to expend energy.”
- D. “Remove clocks from the client’s room.”
Correct answer: C
Rationale: Encouraging physical activity is an effective non-restraint intervention for managing confused clients. It helps reduce agitation, promotes circulation, and may decrease the need for restraints. Choice A is incorrect as using full-length side rails can potentially restrict a client's movement, which is counterproductive to avoiding restraints. Choice B, while emphasizing monitoring, does not directly address alternatives to restraint use. Choice D is also incorrect as removing clocks from the client's room does not directly address managing confusion and reducing the need for restraints.
4. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?
- A. Bleeding time
- B. Coagulation time
- C. Prothrombin time
- D. Partial thromboplastin time
Correct answer: C
Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
5. A healthcare professional is instructing an AP about caring for a client who has a low platelet count. Which of the following instructions is the priority for measuring vital signs for this client?
- A. Avoid measuring the client’s temperature rectally.
- B. Count the client’s radial pulse for 30 seconds and multiply it by 2.
- C. Count the client’s respirations discreetly.
- D. Allow the client to rest for 5 minutes before measuring their BP.
Correct answer: A
Rationale: The correct answer is to avoid measuring the client’s temperature rectally. Rectal temperatures can cause bleeding in clients with low platelet counts. It is crucial to avoid invasive methods that could increase the risk of bleeding or discomfort. Choice B, counting the radial pulse, is not directly related to the risk of bleeding in a client with low platelet count. Choice C, counting respirations discreetly, is important for accuracy but is not the priority when considering the risk of bleeding. Choice D, letting the client rest before measuring blood pressure, is beneficial but is not the priority in preventing potential harm due to low platelet counts.
