HESI Fundamentals Exam
1. The healthcare provider is caring for a client with a history of atrial fibrillation. Which assessment finding would be most concerning?
- A. Blood pressure of 150/90 mmHg
- B. Irregular heart rhythm
- C. Shortness of breath
- D. Fatigue
Correct answer: C
Rationale: Shortness of breath is the most concerning assessment finding in a client with a history of atrial fibrillation. It can indicate a worsening of the condition, pulmonary edema, or the development of a complication such as heart failure. A blood pressure of 150/90 mmHg, while elevated, is not as immediately concerning as respiratory distress in this context. An irregular heart rhythm is expected in atrial fibrillation and may not necessarily be a new or concerning finding. Fatigue is a common symptom in atrial fibrillation but is not as acutely concerning as shortness of breath, which may indicate compromised oxygenation and circulation.
2. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 0.5 mL
- B. 1 mL
- C. 1.5 mL
- D. 2 mL
Correct answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
3. A healthcare provider is planning to initiate IV therapy for an older adult client who requires IV fluids. Which of the following actions should the healthcare provider take?
- A. Insert the IV catheter without using a tourniquet.
- B. Use the tourniquet minimally or not at all to avoid injury to fragile skin or veins.
- C. Insert the IV catheter at a 45-degree angle.
- D. Use a smaller gauge catheter to reduce vein trauma.
Correct answer: B
Rationale: When initiating IV therapy in older adults, it is essential to use the tourniquet minimally or not at all to prevent potential injury to fragile skin or veins. The use of a tourniquet can lead to increased venous pressure and potentially cause vein damage in older adult clients. Choice A is incorrect because inserting the IV catheter without a tourniquet can make locating veins more challenging. Choice C is incorrect as inserting the IV catheter at a 45-degree angle is not a recommended practice and can increase the risk of complications. Choice D is incorrect because using a smaller gauge catheter may not be appropriate for older adults who may require a larger gauge catheter for adequate fluid administration.
4. A client is receiving teaching from a healthcare provider about reducing the adverse effects of immobility. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will perform ankle and knee exercises every hour - Range of motion (ROM) is needed to prevent contractures.
- B. I will hold my breath when rising from a sitting position.
- C. I will remove my antiembolic stockings while I am in bed.
- D. I will have my partner help me change positions every 4 hours.
Correct answer: A
Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.
5. A nurse is caring for a client who is unstable and has vital signs measured every 15 minutes by an electronic blood pressure machine. The nurse notices the machine begins to measure the blood pressure at varied intervals and the readings are inconsistent. Which of the following actions should the nurse take?
- A. Discontinue the machine and measure the blood pressure manually every 15 minutes.
- B. Adjust the machine settings.
- C. Clean the machine to ensure accuracy.
- D. Increase the frequency of the readings.
Correct answer: B
Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.
