CAT Exam Practice Test
1. When should the nurse conduct an Allen’s test?
- A. When obtaining pulmonary artery pressures
- B. To assess for the presence of a deep vein thrombus in the leg
- C. Just before arterial blood gases are drawn peripherally
- D. Prior to attempting a cardiac output calculation
Correct answer: C
Rationale: The correct time to conduct an Allen’s test is just before arterial blood gases are drawn peripherally. This test is performed to assess the adequacy of collateral circulation in the hand before obtaining arterial blood gases. Choice A is incorrect because an Allen’s test is not specifically done when obtaining pulmonary artery pressures. Choice B is incorrect because an Allen’s test is not used to assess deep vein thrombosis. Choice D is incorrect because an Allen’s test is not done specifically before attempting a cardiac output calculation.
2. A client with intestinal obstructions has a nasogastric tube to low intermittent suction and is receiving an IV of lactated Ringer’s at 100 ml/H. Which finding is most important for the nurse to report to the healthcare provider?
- A. Gastric output of 900 mL in the last 24 hours
- B. Serum potassium level of 3.1 mEq/L or mmol/L (SI)
- C. Increased blood urea nitrogen (BUN)
- D. 24-hour intake at the current infusion rate
Correct answer: B
Rationale: The most crucial finding to report to the healthcare provider in this scenario is a serum potassium level of 3.1 mEq/L. Hypokalemia can lead to serious complications, including cardiac issues. Gastric output, increased BUN, and monitoring the 24-hour intake are essential but do not pose an immediate risk as hypokalemia does in this situation.
3. The nurse is developing a teaching plan for a client with acute gastritis caused by drinking contaminated water. The nurse should emphasize the need to report the onset of which problem?
- A. Low-grade fever
- B. Bruising of the skin
- C. Abdominal cramping
- D. Bloody emesis
Correct answer: D
Rationale: The correct answer is D: Bloody emesis. Bloody emesis indicates potential bleeding or severe irritation, which should be reported immediately. In the context of acute gastritis, bloody emesis could indicate a more serious complication that requires urgent medical attention. Choices A, B, and C are not typically associated with acute gastritis caused by contaminated water and do not signal as critical of a condition as bloody emesis. Low-grade fever, bruising of the skin, and abdominal cramping are more commonly associated with other conditions or may be less urgent in this context.
4. Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?
- A. Ensure that the knot can be quickly released.
- B. Tie the knot with a double turn or square knot.
- C. Move the ties so the restraints are secured to the side rails.
- D. Ensure that the restraints are snug against the client's wrist.
Correct answer: A
Rationale: The correct action for the nurse to take before leaving the room is to ensure that the knot can be quickly released. Using a half bow knot to attach the client's wrist restraints allows for quick release in case of an emergency. This is crucial for ensuring the safety of the client and complying with restraint policies. Tying the knot with a double turn or square knot (Choice B) would make it difficult to release quickly when needed. Moving the ties so the restraints are secured to the side rails (Choice C) does not address the immediate need for a quick release. Ensuring that the restraints are snug against the client's wrist (Choice D) may not be appropriate if the restraints need to be quickly removed for the client's safety.
5. A client with active tuberculosis (TB) is receiving isoniazid (INH) and rifampin (RMP) daily, so direct observation therapy (DOT) is initiated while the client is hospitalized. Which instruction should the nurse provide this client?
- A. Describe feelings about taking daily medications
- B. Take medications in the presence of the nurse
- C. Notify the nurse after self-medication is completed
- D. Keep a daily record of all medications taken
Correct answer: B
Rationale: The correct instruction for the nurse to provide the client undergoing direct observation therapy for TB is to take medications in the presence of the nurse. This approach ensures that the client is actually taking the medications as prescribed, reducing the risk of noncompliance. Choice A is incorrect because the focus should be on ensuring the client physically takes the medications rather than discussing feelings. Choice C is incorrect as it does not ensure direct observation. Choice D is incorrect because self-reporting or keeping a record does not guarantee that the client is actually taking the medications.
