HESI CAT Exam 2022
1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
2. The client with diabetes mellitus type 1 has a fruity breath odor. What is the priority nursing action?
- A. Evaluate the client’s intake and output
- B. Measure the client’s capillary blood glucose
- C. Consult with the dietitian about the client’s diet
- D. Apply a pulse oximeter to the client’s finger
Correct answer: B
Rationale: Fruity breath odor in a client with diabetes mellitus type 1 can indicate ketoacidosis, a serious complication. Measuring the client’s capillary blood glucose is the priority nursing action in this scenario as it helps diagnose and manage the condition effectively. Evaluating intake and output may be important for overall assessment but not the priority when dealing with a potential emergency like ketoacidosis. Consulting with a dietitian about the client’s diet is important for long-term management but not the immediate priority. Applying a pulse oximeter is not relevant to addressing the fruity breath odor and suspected ketoacidosis.
3. At 1130, the nurse assumes care of an adult client with diabetes mellitus who was admitted with an infected foot ulcer. After reviewing the client’s electronic health record, which priority nursing action should the nurse implement?
- A. Administer insulin based on the sliding scale
- B. Assess the appearance of the foot wound
- C. Obtain antibiotic peak and trough levels
- D. Initiate hourly measurements of urine output
Correct answer: B
Rationale: Assessing the appearance of the foot wound is the priority action in this scenario. This assessment is crucial to monitor for any signs of infection progression or complications related to the foot ulcer, especially in a client with diabetes mellitus. Administering insulin based on the sliding scale (Choice A) is important but not the immediate priority compared to assessing the foot wound. Obtaining antibiotic peak and trough levels (Choice C) is relevant but not as immediate as assessing the wound for signs of infection. Initiating hourly measurements of urine output (Choice D) is not the priority when compared to assessing the foot wound in a client with an infected foot ulcer.
4. A 17-year-old adolescent is brought to the emergency department by both parents because the adolescent has been coughing and running a fever with flu-like symptoms for the past 24 hours. Which intervention should the nurse implement first?
- A. Obtain a chest X-ray per protocol.
- B. Place a mask on the client’s face.
- C. Assess the client’s temperature.
- D. Determine the client’s blood pressure
Correct answer: B
Rationale: The correct intervention for the nurse to implement first is to place a mask on the client's face. This is crucial to prevent the potential spread of infectious agents to others in the emergency department, considering the presenting symptoms of coughing and fever. Placing a mask helps in containing respiratory secretions and reducing the risk of airborne transmission. Assessing the client’s temperature or blood pressure can be done after ensuring infection control measures. Obtaining a chest X-ray would be a secondary intervention once immediate infection control is addressed.
5. To reduce the risk of symptoms exacerbation for a client with multiple sclerosis (MS), which instructions should the nurse include in the client’s discharge plan? (Select all that apply).
- A. Practice relaxation exercises
- B. Limit fluids to avoid bladder distention
- C. Space activities to allow for rest periods
- D. Avoid persons with infections
Correct answer: A
Rationale: The correct instruction to include in the discharge plan for a client with MS to reduce symptom exacerbation is practicing relaxation exercises. Relaxation exercises can help manage MS symptoms by reducing stress. Limiting fluids to avoid bladder distention is not appropriate as adequate hydration is essential for overall health and helps prevent complications like urinary tract infections. While spacing activities to allow for rest periods can be beneficial for general well-being, it is not directly related to symptom exacerbation in MS. Avoiding persons with infections is important to prevent infections, but it is not specifically targeted at reducing MS symptom exacerbation.
