CAT Exam Practice Test
1. A 37-year-old client diagnosed with chronic kidney disease (CKD) is being treated for renal osteodystrophy. Which nursing diagnosis is most likely to be included in this client’s plan of care?
- A. High risk for infection related to subclavian catheter
- B. High risk of injury related to ambulation
- C. Knowledge deficit related to a high-protein diet
- D. Hygiene self-care deficit related to uremic frost
Correct answer: D
Rationale: The correct answer is D. Uremic frost is a condition in which urea and other waste products are excreted through the skin, leaving a powdery residue. This indicates poor hygiene and self-care, common issues in patients with CKD and renal osteodystrophy. Proper hygiene measures are essential to prevent complications. Choices A, B, and C are less likely to be included in the plan of care for a CKD patient with renal osteodystrophy. Choice A is more related to a vascular access issue, choice B is more related to mobility concerns, and choice C is more related to dietary education.
2. Which assessment is most important for the nurse to perform before ambulating a client with a history of syncope?
- A. Pedal pulses
- B. Breath sounds
- C. Oxygen saturation
- D. Blood pressure
Correct answer: D
Rationale: The correct answer is 'D: Blood pressure.' It is crucial to check the client's blood pressure before ambulating them, especially if they have a history of syncope. Monitoring blood pressure helps to prevent falls by ensuring that the client's blood pressure is stable enough to tolerate the activity. Choices A, B, and C are not as critical in this scenario. Checking pedal pulses, breath sounds, or oxygen saturation is important but not as crucial as assessing blood pressure when preparing to ambulate a client with a history of syncope.
3. The nurse is demonstrating wound care to a client following abdominal surgery. In what order should the nurse teach the technique?
- A. Remove old dressing using clean gloves. Discard gloves with old dressing
- B. Moisten sterile gauze with normal saline. Clean wound from least contaminated area to most contaminated area
- C. Apply sterile gauze dressing to wound area
- D. Secure dressing with tape
Correct answer: A
Rationale: The correct order ensures proper aseptic technique and wound care to prevent infection. The first step is to remove the old dressing using clean gloves to prevent contamination. Discarding the gloves with the old dressing helps maintain cleanliness. Choices B, C, and D are incorrect because cleaning the wound, applying a new dressing, and securing it should come after removing the old dressing to maintain asepsis and prevent infection.
4. After the diagnosis and initial treatment of a 3-year-old with Cystic fibrosis, the nurse provides home care instructions to the mother. Which statement by the child's mother indicates that she understands home care treatment to promote pulmonary functions?
- A. Chest physiotherapy should be performed twice a day before a meal
- B. Energy should be conserved by scheduling minimally strenuous activities
- C. Administer a cough suppressant every 8 hours
- D. Maintain supplemental oxygen at 4 to 6 L/minute
Correct answer: A
Rationale: The correct answer is A. Chest physiotherapy is essential for maintaining pulmonary function in cystic fibrosis. It should be performed regularly, often twice daily, to clear mucus from the lungs. Choice B is incorrect because conserving energy does not directly promote pulmonary function. Choice C is incorrect as cough suppressants are not typically used to promote pulmonary function in cystic fibrosis. Choice D is incorrect as maintaining supplemental oxygen at 4 to 6 L/minute is not a standard home care treatment for promoting pulmonary functions in cystic fibrosis.
5. A 46-year-old male client who had a myocardial infarction 24 hours ago comes to the nurse’s station fully dressed and wanting to go home. He tells the nurse that he is feeling much better at this time. Based on this behavior, which nursing problem should the nurse formulate?
- A. Anxiety related to treatment plan
- B. Deficient knowledge of lifestyle changes
- C. Ineffective coping related to denial
- D. Decisional conflict due to stress
Correct answer: C
Rationale: The correct answer is C: 'Ineffective coping related to denial.' The client's behavior of wanting to go home and feeling much better shortly after a myocardial infarction indicates denial of the severity of his condition. This denial can lead to ineffective coping mechanisms, hindering his recovery and treatment. Choices A, B, and D are incorrect because the client's behavior is not primarily driven by anxiety about the treatment plan, deficient knowledge of lifestyle changes, or decisional conflict due to stress, but rather by denial and ineffective coping mechanisms.
