CAT Exam Practice Test
1. A nurse who works in the nursery is attending the vaginal delivery of a term infant. What action should the nurse complete before leaving the delivery room?
- A. Obtain the infant's vital signs.
- B. Observe the infant latching onto the breast.
- C. Administer a vitamin K injection.
- D. Place the ID bands on the infant and mother.
Correct answer: D
Rationale: Placing ID bands on the infant and mother is crucial to ensure correct identification and prevent mix-ups. This step is essential for maintaining proper identification of the newborn and the mother, facilitating safe care delivery. Before leaving the delivery room, ensuring proper identification is a priority to prevent any errors. Obtaining the infant's vital signs may be important but does not take precedence over ensuring correct identification. Observing the infant latching onto the breast is crucial for breastfeeding initiation but can be done after proper identification. Administering a vitamin K injection is also important but should not delay the immediate identification process.
2. 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.
3. A client is admitted with hepatitis A (HAV) and dehydration. Subjective symptoms include anorexia, fatigue, and malaise. What additional assessment should the nurse expect to find during the preicteric phase?
- A. RUQ abdominal pain
- B. Clay-colored stools
- C. Icteric sclera
- D. Pruritus
Correct answer: A
Rationale: During the preicteric phase of hepatitis A, the nurse should expect to find RUQ (right upper quadrant) abdominal pain. This pain is common in the early phase of hepatitis A and is associated with liver inflammation. Clay-colored stools (Choice B) are typically seen in the icteric phase when there is a lack of bile flow. Icteric sclera (Choice C) refers to yellowing of the eyes, which is a characteristic of the icteric phase. Pruritus (Choice D), which is itching of the skin, is also more commonly associated with the icteric phase when bile salts accumulate in the skin.
4. A 12-year-old client who had an appendectomy two days ago is receiving 0.9% normal saline at 50 ml/hour. The client’s urine specific gravity is 1.035. What action should the nurse implement?
- A. Encourage popsicles and fluids of choice
- B. Evaluate postural blood pressure measurements
- C. Obtain a specimen for urinalysis
- D. Assess bowel sounds in all quadrants
Correct answer: A
Rationale: Encouraging fluids helps address dehydration and potentially high urine specific gravity, which is often related to inadequate fluid intake. In this scenario, the client may be at risk of dehydration due to the appendectomy and the high urine specific gravity. Encouraging popsicles and fluids of choice can help increase fluid intake and improve hydration status. The other options are not the priority at this time. Postural blood pressure measurements may be relevant for assessing fluid status but are not the immediate action needed. Obtaining a specimen for urinalysis and assessing bowel sounds are not the priority actions based on the client's condition.
5. What nursing intervention is most important to implement after a client has completed a myelogram?
- A. Lie-sit-stand blood pressure measurement
- B. Abdominal assessment for distention and bowel sounds
- C. Neurovascular assessment of lower extremities
- D. Assessment of skin temperature and turgor
Correct answer: C
Rationale: The correct answer is C: Neurovascular assessment of the lower extremities. After a myelogram, it is crucial to monitor the neurovascular status to detect any signs of complications such as impaired circulation or nerve damage. This assessment helps in identifying early signs of vascular compromise or neurological deficits. Choices A, B, and D are not the priority after a myelogram. Lie-sit-stand blood pressure measurement is not directly related to post-myelogram care. Abdominal assessment and skin assessment are important but not the priority immediately after this procedure.
