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 nurse on a medical-surgical unit is caring for a client who has a new prescription for wrist restraints. Which of the following actions should the nurse take?
- A. Pad the client’s wrists before applying the restraints
- B. Tie the restraints to the side rails of the bed
- C. Secure the restraints to the bed frame
- D. Use a quick-release knot to tie the restraints
Correct answer: A
Rationale: The correct action for the nurse to take when a client has a new prescription for wrist restraints is to pad the client’s wrists before applying the restraints. This is important to prevent skin breakdown and injury. Tying the restraints to the side rails of the bed (Choice B) is unsafe and can lead to potential harm for the client. Similarly, securing the restraints to the bed frame (Choice C) is not appropriate as it can restrict the client's movement and cause discomfort. Using a quick-release knot to tie the restraints (Choice D) is also incorrect as it may compromise the effectiveness of the restraints in ensuring client safety.
3. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:
- A. Cleanse the entry port prior to withdrawing urine.
- B. Use a sterile syringe to collect urine from the collection bag.
- C. Obtain the specimen from the drainage tubing.
- D. Replace the catheter before obtaining the specimen.
Correct answer: A
Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.
4. When caring for a patient diagnosed with diabetes mellitus and circulatory insufficiency, experiencing peripheral neuropathy and urinary incontinence, on which areas does the nurse focus care?
- A. Decreased pain sensation and increased risk of skin impairment
- B. Decreased caloric intake and accelerated wound healing
- C. High risk for skin infection and low saliva pH level
- D. High risk for impaired venous return and dementia
Correct answer: A
Rationale: The nurse should focus on decreased pain sensation and increased risk of skin impairment due to the patient's conditions. Peripheral neuropathy can lead to decreased pain sensation, making the patient more prone to injuries without realizing it. Additionally, the combination of circulatory insufficiency, peripheral neuropathy, and urinary incontinence can increase the risk of skin breakdown and impaired healing. Choices B, C, and D are incorrect because they do not address the specific issues related to the patient's diagnoses and symptoms.
5. When parents call the emergency room to report that a toddler has swallowed drain cleaner, the nurse instructs them to call for emergency transport to the hospital. While waiting for an ambulance, what substance should the nurse suggest the parents give the child sips of?
- A. Tea
- B. Water
- C. Milk
- D. Soda
Correct answer: B
Rationale: The correct answer is B: Water. Giving sips of water can help dilute the drain cleaner while waiting for emergency transport, which may help reduce the potential harm caused by the ingestion. Choices A, C, and D are incorrect because tea, milk, and soda can interact with the chemicals in the drain cleaner or increase the risk of vomiting, which is not recommended in this situation.
