CAT Exam Practice
1. The nurse instructs an unlicensed assistive personnel (UAP) to turn an immobilized elderly client with an indwelling urinary catheter every two hours. What additional action should the nurse instruct the UAP to take each time the client is turned?
- A. Empty the urinary drainage bag
- B. Feed the client a snack
- C. Offer the client oral fluids
- D. Assess the breath sounds
Correct answer: A
Rationale: The correct additional action the nurse should instruct the UAP to take each time the immobilized elderly client with an indwelling urinary catheter is turned is to empty the urinary drainage bag. This action helps to prevent backflow of urine, reduces the risk of infection, and prevents bladder distention, which are crucial for the client's comfort and health. Choices B, C, and D are incorrect as they are not directly related to the care of a client with an indwelling urinary catheter. Feeding a snack, offering oral fluids, or assessing breath sounds are important aspects of care but not the immediate action needed when turning a client with an indwelling urinary catheter to prevent complications.
2. The nurse is teaching a male adolescent recently diagnosed with type 1 diabetes mellitus (DM) about self-injecting insulin. Which approach is best for the nurse to use to evaluate the effectiveness of the teaching?
- A. Observe him demonstrating the self-injection technique to another diabetic adolescent.
- B. Ask the adolescent to describe his comfort level with injecting himself with insulin.
- C. Review his glycosylated hemoglobin level 3 months after the teaching session.
- D. Have the adolescent list the steps for safe insulin administration.
Correct answer: C
Rationale: Reviewing the glycosylated hemoglobin level after a few months is the best approach to evaluate the effectiveness of teaching self-injection. This measurement provides an objective indicator of the adolescent's glucose control over time, reflecting the impact of insulin self-administration education. Choices A, B, and D do not directly assess the long-term impact of the teaching on the adolescent's diabetes management.
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. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Review of recent laboratory test results shows that the client’s serum magnesium level has decreased below the normal range. In addition to contacting the healthcare provider, what nursing action is most important?
- A. Check the visual difficulties
- B. Note the most recent hemoglobin level
- C. Assess for hand and joint pain
- D. Observe rhythm on telemetry monitor
Correct answer: D
Rationale: The correct answer is to observe the rhythm on the telemetry monitor. Decreased magnesium levels can lead to cardiac issues, such as arrhythmias. Monitoring the heart rhythm is crucial in this situation. Checking visual difficulties (choice A) is not directly related to the potential cardiac effects of low magnesium levels. Noting the hemoglobin level (choice B) and assessing for hand and joint pain (choice C) are not the priority when dealing with low magnesium levels and possible cardiac complications.
5. Why is it important to initiate nursing interventions that promote good nutrition, rest, exercise, and stress reduction for clients diagnosed with an HIV infection?
- A. Prevent the spread of infection to others
- B. Improve the function of the immune system
- C. Increase the ability to carry out activities of daily living
- D. Promote a feeling of general well-being
Correct answer: B
Rationale: The correct answer is B: 'Improve the function of the immune system.' Initiating interventions focusing on good nutrition, rest, exercise, and stress reduction aims to enhance the immune system function in clients with HIV infection. For individuals with HIV, maintaining a strong immune system is crucial in fighting the virus and preventing opportunistic infections. Choices A, C, and D are important aspects of care but are secondary to the primary goal of boosting the immune system to combat the effects of the HIV virus.
