CAT Exam Practice Test

1. 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?

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.

2. The mother of a school-age child calls the school to ask when her daughter can return to school after treatment for Pediculosis capitis. What is the nurse’s best response?

Correct answer: D

Rationale: The correct answer is 'After the treatment kills all the live lice.' The child can return to school once all live lice are eliminated to prevent the spread of Pediculosis capitis. This is essential as live lice are highly contagious. Choices A, B, and C are incorrect. Waiting for the itching to stop or for an epidemic to subside does not ensure that all live lice are eradicated, which is crucial to prevent reinfestation and transmission.

3. What information should the nurse include in the discharge teaching plan of a client with low back pain who is taking cyclobenzaprine to control muscle spasms?

Correct answer: C

Rationale: The correct answer is C: 'Use cold and allergy medications only as directed by a healthcare provider.' It is essential to inform the client not to self-medicate with cold and allergy medications or make changes without consulting a healthcare provider to prevent potential drug interactions or adverse effects. Choice A is incorrect because cyclobenzaprine can be taken with or without food, so there is no specific requirement to take it on an empty stomach. Choice B is incorrect because using heat or ice on injured muscles while taking cyclobenzaprine is generally safe and can help with symptom management. Choice D is also incorrect because discontinuing nonsteroidal anti-inflammatory medications should be done under the guidance of a healthcare provider, but it is not a direct concern related to taking cyclobenzaprine for muscle spasms.

4. Several months after a foot injury, an adult woman is diagnosed with neuropathic pain. The client describes the pain as severe and burning and is unable to put weight on her foot. She asks the nurse when the pain will 'finally go away.' How should the nurse respond?

Correct answer: B

Rationale: The correct answer is B: 'Assist the client in developing a goal of managing the pain.' In cases of chronic neuropathic pain, complete resolution is often not achievable. Therefore, the most appropriate approach is to help the client develop strategies to manage the pain effectively. Choice A is incorrect because it may give false hope of immediate resolution, which is unlikely with neuropathic pain. Choice C is incorrect as it does not directly address the client's need for pain management. Choice D is incorrect as it focuses on functional ability assessment, which is not the priority when addressing the client's pain concerns.

5. Two days after an abdominal hysterectomy, an elderly female with diabetes has a syncopal episode. The nurse determines that her vital signs are within normal limits, but her blood sugar is 325 mg/dL or 18.04 mmol/L (SI). What intervention should the nurse implement first?

Correct answer: A

Rationale: In this case, the nurse should implement the intervention of administering regular insulin per sliding scale. High blood sugar levels, as indicated by a reading of 325 mg/dL, require insulin administration to prevent complications such as hyperglycemia. Canceling the client's dinner tray (choice B) would not address the immediate need to lower the blood sugar level. Giving the client orange juice (choice C) might further increase the blood sugar level as it contains sugar. Administering the next scheduled dose of metformin (choice D) is not appropriate as metformin is not typically used for acute management of high blood sugar levels.
