CAT Exam Practice Test
1. A client with cervical cancer is hospitalized for insertion of a sealed internal cervical radiation implant. While providing care, the nurse finds the radiation implant in the bed. What action should the nurse take?
- A. Call the radiology department
- B. Reinsert the implant into the vagina
- C. Apply double gloves to retrieve the implant for disposal
- D. Place the implant in a lead container using long-handled forceps
Correct answer: D
Rationale: The correct action for the nurse to take when finding a radiation implant in the bed is to place the implant in a lead container using long-handled forceps. This action is crucial to minimize radiation exposure to both the patient and healthcare providers and ensure the safe disposal of the radioactive material. Calling the radiology department (choice A) may lead to unnecessary delays in addressing the immediate safety concern. Reinserting the implant into the vagina (choice B) is contraindicated and can cause harm. Applying double gloves to retrieve the implant for disposal (choice C) is not adequate for ensuring proper containment and handling of the radioactive implant, which requires specialized equipment like a lead container and long-handled forceps.
2. During discharge teaching, the nurse discusses the parameters for weight monitoring with a client recently diagnosed with heart failure (HF). Which information is most important for the client to acknowledge?
- A. Weigh at the same time every day
- B. Report weight gain of 2 pounds (0.9kg) in 24 hours
- C. Maintain a daily weight record
- D. Limit dietary salt intake
Correct answer: B
Rationale: The correct answer is B. Reporting a weight gain of 2 pounds in 24 hours is crucial for detecting fluid retention or worsening heart failure. This rapid weight gain indicates possible fluid overload, which can be a sign of worsening HF. Option A is not as critical as the timing of weighing can vary. Option C is important for tracking trends but does not emphasize the significance of a sudden weight gain. Option D is relevant for managing HF but does not address the immediate need for reporting rapid weight gain.
3. In what order should the nurse assess a lethargic one-hour-old infant brought to the nursery?
- A. Heel stick
- B. Respirations
- C. Heart rate
- D. Temperature
Correct answer: D
Rationale: When assessing a lethargic one-hour-old infant, the nurse should prioritize assessing the most critical parameters first. Temperature and heart rate are vital signs that provide immediate information about the infant's well-being. Therefore, the correct order of assessment should be temperature, heart rate, respirations, and then a heel stick. Temperature is crucial to determine if the infant is hypothermic or hyperthermic, while heart rate gives insight into the circulatory system's function. Respirations follow to evaluate the infant's breathing pattern. Lastly, the heel stick is important for certain screenings but is not as urgent as evaluating temperature and heart rate in a lethargic infant.
4. Following a thyroidectomy, a client experiences tetany. The nurse should expect to administer which intravenous medication?
- A. Sodium iodide solution
- B. Levothyroxine sodium (Synthroid)
- C. Calcium gluconate
- D. Propranolol (Inderal)
Correct answer: C
Rationale: Following a thyroidectomy, tetany can occur due to hypoparathyroidism, leading to low calcium levels. Therefore, the nurse should administer calcium gluconate intravenously to raise the calcium levels. Choice A, Sodium iodide solution, is incorrect as it is used for thyroid conditions, not for treating tetany. Choice B, Levothyroxine sodium (Synthroid), is incorrect as it is a thyroid hormone replacement and does not address low calcium levels. Choice D, Propranolol (Inderal), is incorrect as it is a beta-blocker used for conditions like hypertension and not indicated for tetany after thyroidectomy.
5. The client who is to avoid any weight-bearing on the left leg is using a 3-point crutch gait for ambulation. What is the best action for the nurse to initiate?
- A. Encourage continued use of the 3-point crutch gait by the client
- B. Encourage the client to use a wheelchair for mobility
- C. Instruct the client in the use of a 4-point crutch gait
- D. Instruct the client in the use of a 2-point crutch gait
Correct answer: C
Rationale: In this scenario, the client needs to avoid weight-bearing on the left leg. A 4-point crutch gait involves using both crutches and both legs, making it more appropriate for weight-bearing restrictions. Encouraging the use of a 3-point gait (choice A) would not provide adequate support for the client's condition. While using a wheelchair (choice B) could be an option, instructing the client in a 4-point crutch gait would promote mobility while adhering to weight-bearing restrictions. A 2-point crutch gait (choice D) involves using both crutches and one leg, which is not suitable for avoiding weight-bearing on the left leg.
