CAT Exam Practice Test
1. The urinary drainage of a client with continuous bladder irrigation is becoming increasingly red. Which intervention should the nurse implement?
- A. Increase the irrigation rate
- B. Lower the head of the bed
- C. Milk the catheter tubing
- D. Evaluate for fluid overload
Correct answer: A
Rationale: Increasing the irrigation rate can help clear any blood clots and reduce the redness in the urinary drainage. This intervention aims to improve the flushing of the bladder and potentially resolve the issue. Lowering the head of the bed would not directly address the red urinary drainage. Milking the catheter tubing is not recommended as it can cause trauma to the catheter or bladder, leading to further complications. While evaluating for fluid overload is an important nursing consideration, it does not directly address the immediate concern of redness in the urinary drainage, which requires a focused intervention to clear any blockages or clots in the system.
2. Which action should the school nurse take first when conducting a screening for scoliosis?
- A. Compare dorsal trunk measurements
- B. Have the individual extend arms over the head for visualization
- C. Inspect for symmetrical shoulder height
- D. Observe weight-bearing on each leg
Correct answer: C
Rationale: Inspecting for symmetrical shoulder height is a crucial initial step in screening for scoliosis. Asymmetry in shoulder height can indicate the presence of spinal curvature, which is a key indicator of scoliosis. This assessment is prioritized as it provides a visual clue to potential spinal abnormalities. Choices A, B, and D are not the first steps in scoliosis screening. Choice A involves a more detailed measurement that is not the primary visual indicator for scoliosis; choice B is not a primary indicator of scoliosis but can be used for further examination, and choice D is not directly related to identifying spinal curvature.
3. A male client with schizophrenia tells the nurse that the hospital has installed cameras that watch him and listening devices that record what everyone says. Which nursing problem should the nurse document for this client?
- A. Noncompliance with medication related to thought broadcasting
- B. Situational self-esteem disturbance secondary to schizophrenia
- C. Disturbed sensory perception related to auditory hallucinations
- D. Impaired environmental interpretation related to paranoid delusions
Correct answer: D
Rationale: The correct answer is D: Impaired environmental interpretation related to paranoid delusions. The client's belief about cameras watching and recording him is a manifestation of paranoid delusions, indicating a misinterpretation of the environment. Choice A is incorrect because thought broadcasting is not directly related to the client's belief about surveillance equipment. Choice B is incorrect as self-esteem disturbance is not the primary issue presented. Choice C is also incorrect as the client is not experiencing auditory hallucinations but rather paranoid delusions about surveillance.
4. After years of struggling with weight management, a middle-aged man is evaluated for gastroplasty. He has experienced difficulty managing his diabetes mellitus and hypertension, but he is approved for surgery. Which intervention is most important for the nurse to include in this client’s plan of care?
- A. Monitor for signs of depression
- B. Apply sequential compression stockings
- C. Provide a wide variety of meal choices
- D. Observe for signs of depression
Correct answer: D
Rationale: Observing for signs of depression is crucial in this patient's plan of care as depression can impact his overall recovery and management post-surgery. Depression is common in individuals struggling with weight management, diabetes mellitus, and hypertension. Monitoring for urinary incontinence (Choice A) is not the priority in this case as the patient is undergoing gastroplasty for weight management, not a urinary issue. Applying sequential compression stockings (Choice B) is important for preventing deep vein thrombosis in immobile patients but is not the priority in this scenario. Providing a wide variety of meal choices (Choice C) is not the most crucial intervention at this stage, as post-gastroplasty dietary restrictions are essential for successful weight management.
5. The charge nurse of a cardiac telemetry unit is assigning client care to a registered nurse (RN) and a practical nurse (PN). Which client should be assigned to the RN?
- A. One day after a permanent pacemaker insertion, a client's telemetry monitor shows a pacer rhythm.
- B. Two hours after undergoing cardioversion, a client's telemetry monitor shows a normal sinus rhythm.
- C. A client started on carvedilol the previous day for heart failure has controlled atrial fibrillation.
- D. Four hours after admission, a client with syncope shows complete heart block on the telemetry monitor.
Correct answer: D
Rationale: The correct answer is D because complete heart block is a critical condition that requires immediate assessment and management by a registered nurse (RN). In complete heart block, there is a significant conduction disturbance that can lead to serious complications. The RN is better equipped to handle such complex and potentially life-threatening situations. Choices A, B, and C involve less critical conditions that can be managed by a practical nurse (PN) under the supervision of the RN. Therefore, assigning the client with complete heart block to the RN ensures prompt and appropriate intervention.
