CAT Exam Practice
1. A female client presents to the emergency department in the early evening complaining of abdominal cramping, watery diarrhea, and vomiting. She tells the nurse that she was at a picnic and ate barbecue that afternoon. What question is most important for the triage nurse to ask this client?
- A. Have you recently traveled outside the United States?
- B. How high was your temperature when you returned home?
- C. Have you taken any medication to treat these symptoms?
- D. Is anyone else sick who was also at the picnic?
Correct answer: D
Rationale: The most important question for the triage nurse to ask the client in this scenario is whether anyone else who attended the picnic is also sick. This is crucial to identify a potential outbreak or common source of infection. Asking about recent travel may be important for infectious diseases but is not as relevant as identifying a common source among individuals who shared the same food. Inquiring about the client's temperature is important but does not provide immediate insight into the cause of symptoms. Asking about medication taken is relevant but not as critical as determining if others are affected, which could indicate a foodborne illness.
2. A client who is diagnosed with amyotrophic lateral sclerosis (ALS) is having difficulty swallowing and articulating words. Which intervention is most important to include in this client’s plan of care?
- A. Encourage speaking slowly and articulating words
- B. Sit upright and flex chin forward while swallowing
- C. Position a communication board at the bedside
- D. Provide feeding utensils with large grip handles
Correct answer: B
Rationale: The correct intervention for a client with ALS experiencing difficulty swallowing and articulating words is to sit upright and flex the chin forward while swallowing. This position helps manage dysphagia associated with ALS by facilitating the swallowing process. Encouraging speaking slowly and articulating words (Choice A) may be helpful for speech clarity but does not address the swallowing issue. Positioning a communication board (Choice C) would not directly address the swallowing difficulty. Providing feeding utensils with large grip handles (Choice D) is not the priority intervention for managing dysphagia in ALS.
3. The healthcare provider prescribes a fluid challenge of 0.9% sodium chloride 1,000 ml to be infused over 4 hours. The IV administration set delivers 10gtt/ml. How many gtt/minute should the nurse regulate the infusion? (Enter a numeric value only. If rounding is required, round to the nearest whole number.)
- A. 42
- B.
- C.
- D.
Correct answer: A
Rationale: To calculate the rate: (1000 ml / 4 hours) = 250 ml/hour; (250 ml/hour) / (60 minutes/hour) = 4.17 ml/minute; (4.17 ml/minute) * (10 gtt/ml) = 41.7 gtt/minute, rounded to 42 gtt/minute. Therefore, the nurse should regulate the infusion at 42 gtt/minute to deliver the prescribed fluid challenge accurately. The other choices are incorrect as they do not reflect the correct calculation based on the given information.
4. To prevent aspiration in a client on mechanical ventilation receiving continuous enteral feedings through a nasogastric tube, which intervention is most important for the nurse to implement?
- A. Verify the feeding tube position with a daily chest x-ray
- B. Maintain head of bed elevated while enteral feeding is infusing
- C. Check feeding tube placement with air bolus prior to use
- D. Aspirate stomach contents every 4 hours to assess residuals
Correct answer: B
Rationale: The most important intervention to prevent aspiration in a client receiving continuous enteral feedings through a nasogastric tube while on mechanical ventilation is to maintain the head of the bed elevated while the feeding is infusing. This position helps reduce the risk of regurgitation and aspiration. Options A, C, and D are not as crucial as maintaining proper positioning to prevent aspiration. Verifying tube position with a daily chest x-ray is important but not the most crucial. Checking tube placement with an air bolus and aspirating stomach contents are important procedures but do not directly address the prevention of aspiration during enteral feedings.
5. In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?
- A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
- B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
- C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
- D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.
Correct answer: A
Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
