CAT Exam Practice
1. The nurse instructs an unlicensed assistive personnel (UAP) to turn an immobilized elderly client with an indwelling urinary catheter every two hours. What additional action should the nurse instruct the UAP to take each time the client is turned?
- A. Empty the urinary drainage bag
- B. Feed the client a snack
- C. Offer the client oral fluids
- D. Assess the breath sounds
Correct answer: A
Rationale: The correct additional action the nurse should instruct the UAP to take each time the immobilized elderly client with an indwelling urinary catheter is turned is to empty the urinary drainage bag. This action helps to prevent backflow of urine, reduces the risk of infection, and prevents bladder distention, which are crucial for the client's comfort and health. Choices B, C, and D are incorrect as they are not directly related to the care of a client with an indwelling urinary catheter. Feeding a snack, offering oral fluids, or assessing breath sounds are important aspects of care but not the immediate action needed when turning a client with an indwelling urinary catheter to prevent complications.
2. A client with deep vein thrombosis (DVT) in the left leg is on a heparin protocol. Which intervention is most important for the nurse to include in this client's plan of care?
- A. Observe for bleeding side effects related to heparin therapy.
- B. Assess blood pressure and heart rate at least every 4 hours.
- C. Measure calf girth to evaluate edema in the affected leg.
- D. Encourage mobilization to prevent pulmonary embolism.
Correct answer: A
Rationale: The correct answer is to 'Observe for bleeding side effects related to heparin therapy.' This is the most crucial intervention for a client with deep vein thrombosis (DVT) on a heparin protocol. Heparin, being an anticoagulant, increases the risk of bleeding as a side effect. Therefore, close monitoring for signs of bleeding, such as bruising, petechiae, or blood in stool or urine, is essential to prevent severe complications. While assessing blood pressure and heart rate (Choice B) is important, it is not as critical as monitoring for bleeding. Measuring calf girth (Choice C) may help evaluate edema but is not as vital as observing for bleeding complications. Encouraging mobilization (Choice D) is beneficial for preventing complications like pulmonary embolism, but in this scenario, monitoring for bleeding takes precedence due to the immediate risk associated with anticoagulant therapy.
3. After medicating the client for pain and collecting granules and stones from strained urine, which action is most important for the nurse to implement next?
- A. Send the calculi for laboratory analysis of stone composition.
- B. Evaluate the client for persistent pain.
- C. Assess the clarity of urine.
- D. Encourage high fluid intake to produce urine output of 2L/day.
Correct answer: A
Rationale: Sending the calculi for analysis is crucial in determining the type of stone present. Identifying the stone composition helps in developing an effective treatment plan and preventive measures to avoid future episodes of urolithiasis. This step is essential in providing targeted care for the client. Options B, C, and D are not the most important actions at this point. While evaluating for persistent pain is essential, determining the stone composition takes precedence to guide appropriate interventions.
4. A postoperative client returns to the nursing unit following a ureterolithotomy via a flank incision. Which potential nursing problem has the highest priority when planning nursing care for this client?
- A. Ineffective airway clearance
- B. Altered nutrition less than body requirements
- C. Fluid volume excess
- D. Activity intolerance
Correct answer: A
Rationale: In this scenario, the highest priority nursing problem for the postoperative client following a ureterolithotomy via a flank incision is ineffective airway clearance. After surgery, there is a risk of airway obstruction due to factors like anesthesia, positioning during surgery, or the presence of secretions. Maintaining a clear airway is crucial to prevent respiratory complications, such as atelectasis or pneumonia. Altered nutrition, fluid volume excess, and activity intolerance are important considerations but are secondary to the immediate threat of compromised airway clearance in the postoperative period.
5. The healthcare provider is completing a head-to-toe assessment for a client admitted for observation after falling out of a tree. Which finding warrants immediate intervention by the healthcare provider?
- A. Sluggish pupillary response to light
- B. Clear fluid leaking from the nose
- C. Complaint of severe headache
- D. Periorbital ecchymosis of the right eye
Correct answer: B
Rationale: Clear fluid leaking from the nose is concerning for cerebrospinal fluid leakage, which is a medical emergency requiring immediate intervention. Sluggish pupillary response to light may indicate neurological issues but is not as urgent as CSF leakage. Complaint of severe headache is important but not as critical as the possibility of CSF leakage. Periorbital ecchymosis of the right eye could be indicative of trauma but does not pose an immediate threat to the patient's life.
