CAT Exam Practice
1. A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client’s plan of care?
- A. Monitor the client’s cardiac activity via telemetry.
- B. Maintain venous access with an infusion of normal saline.
- C. Assess glucose levels via finger stick every 4 to 6 hours.
- D. Evaluate hourly urine output for the return of normal renal function.
Correct answer: A
Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client’s cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
2. A heparin infusion is prescribed for a client who weighs 220 pounds. After administering a bolus dose of 80 units/kg, the nurse calculates the infusion rate for the heparin sodium at 18 units/kg/hour. The available solution is Heparin Sodium 25,000 units in 5% Dextrose Injection 250 ml. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: B
Rationale: To calculate the infusion rate, first, find the total dose required per hour, which is the patient's weight (220 pounds) multiplied by the prescribed rate (18 units/kg/hour). This equals 3960 units/hour. Next, determine how many ml of the solution contain 25,000 units; this is 250 ml. Divide the total dose required per hour (3960 units) by the units per ml (25,000 units/250 ml) to find how many ml are needed per hour. This results in 27 ml/hour. Therefore, the nurse should program the infusion pump to deliver 27 ml/hour. Choice A (18) is incorrect as it does not account for the concentration of the heparin solution. Choices C (36) and D (45) are incorrect as they do not reflect the accurate calculations based on the patient's weight and the heparin concentration in the solution.
3. Following morning care, a client with C-5 spinal cord injury who is sitting in a wheelchair becomes flushed and complains of a headache. Which intervention should the nurse implement first?
- A. Check for any kinks or obstructions in the client’s Foley tubing
- B. Assess the client’s blood pressure every 15 minutes
- C. Administer a prescribed PRN dose of hydralazine (Apresoline)
- D. Educate the client on recognizing symptoms of dysreflexia
Correct answer: B
Rationale: In a client with a C-5 spinal cord injury experiencing flushing and a headache, the priority intervention is to assess the client's blood pressure every 15 minutes. These symptoms could indicate autonomic dysreflexia, a potentially life-threatening condition. Assessing the blood pressure is crucial to identify and address this emergency situation promptly. Checking for kinks or obstructions in the Foley tubing (Choice A) is important but not the priority in this scenario. Administering hydralazine (Choice C) without knowing the blood pressure could be harmful as it may lead to a sudden drop in blood pressure. Educating the client on recognizing symptoms of dysreflexia (Choice D) is important for long-term management but is not the immediate action needed in this acute situation.
4. After receiving report, which client should the nurse assess last?
- A. An older client with dark red drainage on a postoperative dressing, but no drainage in the Hemovac
- B. An adult client with no postoperative drainage in the Jackson-Pratt drain with the bulb compressed
- C. An older client with a distended abdomen and no drainage from the nasogastric tube
- D. An adult client with rectal tube draining clear pale red liquid drainage
Correct answer: D
Rationale: The correct answer is D because the client with rectal tube drainage of clear pale red liquid is likely to be the least urgent since this is a normal post-operative finding. Clear pale red liquid drainage from a rectal tube is typically not a cause for immediate concern. Choices A, B, and C present clients with concerning signs that may require more immediate assessment and intervention. A client with dark red drainage on a postoperative dressing may indicate active bleeding, a client with a compressed Jackson-Pratt drain bulb may have inadequate drainage resulting in complications, and a client with a distended abdomen and no drainage from the nasogastric tube may be experiencing gastrointestinal issues that need prompt evaluation.
5. Which situation is a violation of client confidentiality, as described in the Health Insurance Portability and Accountability Act (HIPAA)?
- A. A sign-in sheet kept at the front desk listing clients' last names and the time of their arrival
- B. A nurse's handwritten notes from a telephone report discarded in the office wastebasket
- C. A computer monitor screen located at the nurse's station in a high-traffic area
- D. Privileged Health Information (PHI) given to an ambulance driver for the transfer of a client
Correct answer: C
Rationale: Choice C is a violation of client confidentiality as it exposes patient information to unauthorized individuals due to its location in a high-traffic area. HIPAA regulations require that electronic protected health information (ePHI) be safeguarded against unauthorized access, making the situation described in choice C a violation. Choices A, B, and D do not directly involve the exposure of patient information to unauthorized individuals. While choices A and B may pose some risks, they are not as severe as the direct exposure described in choice C. Choice D involves sharing information with an ambulance driver for a legitimate purpose, which does not violate HIPAA if done securely and in compliance with regulations.
