HESI LPN
HESI Practice Test for Fundamentals
1. A client with a history of severe anxiety is scheduled for surgery. Which preoperative medication is the most appropriate for the LPN/LVN to administer to this client?
- A. Lorazepam (Ativan)
- B. Morphine sulfate
- C. Meperidine (Demerol)
- D. Promethazine (Phenergan)
Correct answer: A
Rationale: Lorazepam (Ativan) is the most appropriate preoperative medication for a client with severe anxiety. Lorazepam belongs to the benzodiazepine class and is commonly used to manage anxiety before surgical procedures due to its anxiolytic properties. Morphine sulfate and Meperidine (Demerol) are opioid analgesics, not typically indicated for preoperative anxiety. Promethazine (Phenergan) is an antihistamine used for nausea and vomiting, not anxiety management.
2. A client has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?
- A. Monitor blood glucose levels daily.
- B. Change the PN infusion bag every 24 hours.
- C. Prepare the client for a central venous line.
- D. Administer the PN and fat emulsion together.
Correct answer: C
Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.
3. A client is scheduled for an IVP (Intravenous Pyelogram). Which of the following data from the client's history indicates a potential hazard for this test?
- A. Reflex incontinence
- B. Allergic to shellfish
- C. Claustrophobia
- D. Hypertension
Correct answer: B
Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.
4. A cerebrovascular accident patient is placed on a ventilator. The client’s daughter arrives with a durable power of attorney and a living will that indicates no extraordinary life-saving measures. What action should the nurse take?
- A. Refer to the risk manager
- B. Notify the healthcare provider
- C. Discontinue the ventilator
- D. Review the medical record
Correct answer: B
Rationale: The correct action for the nurse to take is to notify the healthcare provider. In this situation, involving the healthcare provider ensures appropriate review and adherence to legal and ethical standards based on the living will and durable power of attorney. Referring to the risk manager may not be directly related to the immediate decision-making process regarding the ventilator. Discontinuing the ventilator without proper authorization from the healthcare provider could lead to legal and ethical implications. Reviewing the medical record alone may not provide guidance on how to proceed with the specific instructions from the living will and durable power of attorney.
5. A client with a history of heart failure presents with increased shortness of breath and swelling in the legs. What is the most important assessment for the LPN/LVN to perform?
- A. Monitor the client's oxygen saturation level.
- B. Assess the client's apical pulse.
- C. Check for jugular vein distention.
- D. Measure the client's urine output.
Correct answer: C
Rationale: Checking for jugular vein distention is crucial in assessing fluid overload in clients with heart failure. Jugular vein distention indicates increased central venous pressure, which can be a sign of worsening heart failure. Monitoring oxygen saturation (Choice A) is important but may not provide immediate information on fluid status. Assessing the apical pulse (Choice B) is relevant for monitoring heart rate but may not directly indicate fluid overload. Measuring urine output (Choice D) is essential for assessing renal function and fluid balance but does not provide immediate information on fluid overload in this scenario.
