CAT Exam Practice Test
1. While caring for a client with bilateral chest tubes, the bubbling in the water-seal chamber of the right chest tube stops. What action is most important for the nurse to take?
- A. Check the chest tube connections to the water-seal container
- B. Replace the water-seal collection container
- C. Increase the amount of wall suction connected to the right chest tube
- D. Milk the tubing connected to the right chest tube
Correct answer: A
Rationale: The most important action for the nurse to take when the bubbling in the water-seal chamber of the right chest tube stops is to check the chest tube connections to the water-seal container. This is crucial to ensure there are no disconnections or leaks affecting the bubbling. Replacing the water-seal collection container (choice B) is not necessary unless there is a malfunction; increasing suction (choice C) without assessing the connections can be harmful, and 'milking' the tubing (choice D) is an inappropriate action that can cause damage to the system.
2. Two weeks following a Billroth II (gastrojejunostomy), a client develops nausea, diarrhea, and diaphoresis after every meal. When the nurse develops a teaching plan for this client, which expected outcome statement is the most relevant?
- A. Describes a schedule for antacid use in combination with other prescribed medications
- B. Selects a pattern of small meals interspersed with fluid intake
- C. Commits to engaging in a variety of stress reduction techniques
- D. Expresses a commitment to decrease nicotine intake
Correct answer: B
Rationale: The symptoms described are indicative of dumping syndrome, a common complication following a Billroth II procedure. Dumping syndrome presents with symptoms such as nausea, diarrhea, and diaphoresis after meals. To manage these symptoms effectively, the client should opt for small, frequent meals and avoid consuming fluids along with meals. Choice A is inaccurate because antacid use does not directly address the symptoms of dumping syndrome. Choice C is irrelevant as stress reduction techniques are not the primary intervention for dumping syndrome. Choice D is unrelated to the symptoms experienced by the client, making it an inappropriate choice.
3. An adult suffered burns to the face and chest resulting from a grease fire. On admission, the client was intubated, and a 2-liter bolus of normal saline was administered IV. Currently, the normal saline is infusing at 250 ml/hour. The client’s heart rate is 120 beats/minute, blood pressure is 90/50 mmHg, respirations are 12 breaths/minute over the ventilated 12 breaths for a total of 24 breaths/minute, and the central venous pressure (CVP) is 4 mm H2O. Which intervention should the nurse implement?
- A. Increase the rate of normal saline infusion
- B. Infuse an additional bolus of normal saline
- C. Lower the head of the bed to a recumbent position
- D. Bring a tracheostomy tray to the bedside
Correct answer: B
Rationale: The correct intervention is to infuse an additional bolus of normal saline. The client's presentation with a heart rate of 120 beats/minute, hypotensive blood pressure of 90/50 mmHg, and low CVP of 4 mm H2O indicates hypovolemic shock. Administering more normal saline can help in restoring intravascular volume and improving perfusion. Increasing the rate of normal saline infusion (Choice A) is not the best choice as it may lead to fluid overload. Lowering the head of the bed to a recumbent position (Choice C) could worsen hypotension by reducing venous return. Bringing a tracheostomy tray to the bedside (Choice D) is not a priority at this time as the client is already intubated, and the immediate concern is addressing the hypovolemia.
4. 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.
5. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, “Amoxicillin (Amoxil) suspension 200 mg/5 ml.†How many ml should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
- A. 12.5
- B. 7.5
- C. 10.0
- D. 15.0
Correct answer: A
Rationale: To calculate the amount in ml that the nurse should administer every 8 hours, first, determine the amount of amoxicillin needed per dose. 1.5 grams daily divided by 3 doses equals 0.5 grams per dose. Since 0.5 grams is equivalent to 500 mg (1 gram = 1000 mg), and each 5 ml of the suspension contains 200 mg of amoxicillin, the nurse needs to administer (500 mg / 200 mg) * 5 ml = 12.5 ml every 8 hours. Therefore, the correct answer is 12.5 ml. Choices B, C, and D are incorrect because they do not reflect the accurate calculation based on the provided information.
