HESI Fundamentals Practice Test
1. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?
- A. Superficial veins are more easily found in the feet and ankles.
- B. A decreased flow rate could lead to thrombosis formation.
- C. It is more challenging to move a cannulated extremity when using the leg or foot.
- D. Veins in the feet and ankles are located deep, making the procedure more painful.
Correct answer: B
Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
2. At 42-weeks gestation, a client refuses induction and desires a natural delivery. What is the most important action for the nurse to take?
- A. Discuss alternative ways to support her birth plan.
- B. Explain the indications for induction in post-term pregnancy.
- C. Discuss the differences between labor with oxytocin and natural labor.
- D. Ask the healthcare provider to discuss the issue with the client.
Correct answer: A
Rationale: The correct answer is to discuss alternative ways to support her birth plan. It is crucial to respect the client's autonomy and desires while ensuring their safety and well-being. Choice B is incorrect because while educating the client about the indications for induction is important, it is not the most immediate action to take in this scenario. Choice C is incorrect as it focuses on comparing labor types rather than supporting the client's birth plan. Choice D is incorrect as the nurse should first engage with the client directly before involving the healthcare provider.
3. After the administration of t-PA, what should the nurse do?
- A. Observe the client for chest pain.
- B. Monitor for fever.
- C. Review the 12-lead electrocardiogram (ECG).
- D. Auscultate breath sounds.
Correct answer: A
Rationale: After the administration of t-PA, the nurse should observe the client for chest pain. Chest pain post t-PA administration could indicate reocclusion of the coronary artery, a serious complication that requires immediate intervention. Monitoring for fever (choice B) is not specifically associated with t-PA administration. While reviewing the 12-lead ECG (choice C) is important for assessing cardiac function, it may not be the immediate priority right after t-PA administration. Auscultating breath sounds (choice D) is important for assessing respiratory status but is not the most crucial assessment following t-PA administration.
4. A nurse is assessing a postoperative client on an hourly basis. The nurse notes that the client’s urine output for the past hour was 25 mL. Based on this finding, the nurse first:
- A. Calls the physician
- B. Increases the rate of the IV infusion
- C. Checks the client’s overall intake and output record
- D. Administers a 250-mL bolus of normal saline solution (0.9%)
Correct answer: C
Rationale: Clients are at risk of hypovolemia postoperatively, and decreased urine output can be an early sign. However, to accurately interpret this finding, the nurse must assess the overall fluid balance by checking the client’s intake and output records. Increasing the IV infusion rate or administering a bolus of normal saline solution without a physician's order would not be appropriate as these interventions require a prescription. The physician should be notified once the nurse has collected all necessary assessment data, including fluid status and vital signs.
5. The healthcare provider is assessing a 2-hour-old infant born by cesarean delivery at 39-weeks gestation. Which assessment finding should receive the highest priority when planning the infant’s care?
- A. Blood pressure 76/42 mmHg.
- B. Faint heart murmur.
- C. Respiratory rate of 76 breaths/minute.
- D. Blood glucose 45 mg/dl.
Correct answer: C
Rationale: A high respiratory rate in a newborn is concerning as it may indicate respiratory distress, which requires immediate attention to ensure adequate oxygenation. Monitoring and addressing respiratory issues take precedence over other parameters in the initial assessment of a newborn. The blood pressure, heart murmur, and blood glucose levels are important but not as urgent as addressing potential respiratory distress in a newborn.
