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 charge nurse is discussing the responsibility of nurses caring for clients who have a Clostridium difficile infection. Which of the following information should the nurse include in the teaching?
- A. Assign the client to a room with a negative air-flow system.
- B. Use alcohol-based hand sanitizer when leaving the client's room.
- C. Clean contaminated surfaces in the client's room with a phenol solution.
- D. Have family members wear a gown and gloves when visiting.
Correct answer: D
Rationale: When caring for clients with Clostridium difficile infection, it is important to prevent the transmission of spores. Having family members wear a gown and gloves when visiting helps reduce the spread of the infection. Choices A, B, and C are incorrect because assigning the client to a room with a negative air-flow system, using alcohol-based hand sanitizer, and cleaning surfaces with a phenol solution are not specific measures targeted at preventing the transmission of Clostridium difficile spores.
3. A client with brain cancer is transferring to hospice care. The client's son tells the nurse, 'I don’t know what to tell my dad if he asks how he is going to die.' Which of the following is an appropriate response by the nurse?
- A. “Let’s talk more about your dad’s condition.”
- B. “The social worker will help you answer those questions.”
- C. “I think that you should discuss this with the hospice nurse.”
- D. “Try to help your dad enjoy this time as much as he can.”
Correct answer: D
Rationale: Choosing option D, 'Try to help your dad enjoy this time as much as he can,' is the most appropriate response by the nurse. This response shows empathy and compassion towards the client and their family during this difficult transition. The focus on supporting the client in enjoying their remaining time reflects a holistic approach to care. Options A, B, and C are not the best responses in this situation. Option A could lead to unnecessary details that might be overwhelming for the family. Option B shifts the responsibility to the social worker without providing immediate support. Option C deflects the son's concerns to another healthcare professional when emotional support is needed.
4. The client has a nasogastric (NG) tube in place for decompression. What action should the LPN/LVN take to maintain patency of the NG tube?
- A. Irrigate the tube with normal saline every shift.
- B. Check the tube placement by auscultation.
- C. Secure the tube to the client's gown.
- D. Flush the tube with 5 mL of sterile water before and after medication administration.
Correct answer: A
Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.
5. 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.
