CAT Exam Practice Test
1. Which client’s vital signs indicate increased intracranial pressure (ICP) that the nurse should report to the healthcare provider?
- A. P 70, BP 120/60 mmHg; P 100, BP 90/60 mmHg; rapid respirations.
- B. P 55, BP 160/70 mmHg; P 50, BP 194/70 mmHg; irregular respirations.
- C. P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations.
- D. P 110, BP 130/70 mmHg; P 100, BP 110/70 mmHg; shallow respirations.
Correct answer: C
Rationale: Choice C is the correct answer. The vital signs presented (P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations) indicate increased intracranial pressure (ICP), which can be a serious condition requiring immediate medical attention. Kussmaul respirations are deep and labored breathing patterns associated with metabolic acidosis and can be a late sign of increased ICP. Choices A, B, and D do not demonstrate vital sign patterns consistent with increased ICP. Choice A shows variations in blood pressure and pulse rate but does not provide a clear indication of increased ICP. Choice B displays fluctuations in blood pressure and pulse rate with irregular respirations, but these vital signs do not specifically suggest increased ICP. Choice D presents relatively stable vital signs with shallow respirations, which do not align with the typical vital signs seen in increased ICP.
2. The nurse is caring for a client with a tracheostomy. Which action should the nurse perform when suctioning the tracheostomy tube?
- A. Increase wall suction while removing the suction catheter
- B. Instill 10 ml of sterile saline into the tracheostomy tube before applying continuous suction
- C. Suction the client’s oropharynx after tracheal suctioning
- D. Insert the suction catheter into the trachea, and apply intermittent suction with removal of the catheter
Correct answer: D
Rationale: When suctioning a tracheostomy tube, it is essential to insert the suction catheter into the trachea and apply intermittent suction with removal of the catheter. This technique helps prevent damage to the trachea and reduces discomfort for the client. Choice A is incorrect because increasing wall suction with the removal of the suction catheter can cause trauma to the tracheal mucosa. Choice B is incorrect because instilling saline into the tracheostomy tube before suctioning is not recommended as it can lead to complications. Choice C is incorrect as oropharyngeal suctioning should be done before tracheal suctioning to prevent the risk of aspiration.
3. When attempting to establish risk reduction strategies in a community, the nurse notes that regional studies indicate a high number of persons with growth stunting and irreversible mental deficiencies caused by hypothyroidism (cretinism). The nurse should seek funding to implement which screening measure?
- A. T3 levels in school-aged children
- B. T4 levels in newborns
- C. TSH levels in women over 45
- D. Iodine levels in all persons over 60
Correct answer: B
Rationale: Screening T4 levels in newborns is crucial as it helps in the early detection of hypothyroidism, which can prevent conditions like cretinism. Checking T3 levels in school-aged children (Choice A) is not the most appropriate measure for early detection of hypothyroidism in newborns. Monitoring TSH levels in women over 45 (Choice C) is not directly related to detecting hypothyroidism in newborns. Additionally, monitoring iodine levels in all persons over 60 (Choice D) is not specifically aimed at early detection of hypothyroidism in newborns, which is crucial to prevent cretinism.
4. After changing to a new brand of laundry detergent, an adult male reports that he has a fine itchy rash. Which assessment finding warrants immediate intervention by the nurse?
- A. Bilateral Wheezing
- B. Urticaria
- C. Peripheral edema
- D. Elevated blood pressure
Correct answer: B
Rationale: The correct answer is B: Urticaria. An itchy rash following a change in detergent may indicate an allergic reaction, specifically urticaria (hives), which requires immediate attention. Urticaria can be a sign of a severe allergic reaction, such as anaphylaxis. Bilateral wheezing (choice A) may suggest respiratory issues like asthma but is not directly related to the skin rash. Peripheral edema (choice C) and elevated blood pressure (choice D) are not typically associated with an allergic reaction to laundry detergent and would not be the priority assessment findings in this scenario.
5. A client with a history of dementia has become increasingly confused at night and is picking at an abdominal surgical dressing and the tape securing the intravenous (IV) line. The abdominal dressing is no longer occlusive, and the IV insertion site is pink. What intervention should the nurse implement?
- A. Replace the IV site with a smaller gauge.
- B. Redress the abdominal incision.
- C. Leave the lights on in the room at night.
- D. Apply soft bilateral wrist restraints.
Correct answer: C
Rationale: The correct intervention for a client with dementia who is becoming increasingly confused at night and interfering with dressings and IV lines is to leave the lights on in the room at night. This intervention can help reduce confusion and disorientation. Choice A is incorrect because changing the IV site gauge is not the priority in this situation. Choice B is not necessary unless there are signs of infection or other complications at the abdominal incision site, which are not mentioned in the scenario. Choice D should be avoided as using restraints should be a last resort and is not indicated in this case.
