CAT Exam Practice Questions
Question 1 of 9
A client is admitted to the intensive care unit with diabetes insipidus due to a pituitary gland tumor. Which potential complication should the nurse monitor closely?
Correct Answer: A
Rationale: The correct answer is A: Hypokalemia. In diabetes insipidus, there is excessive urination leading to fluid loss, which can result in electrolyte imbalances such as hypokalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices B, C, and D are incorrect. Ketonuria is typically seen in diabetic ketoacidosis, peripheral edema is more commonly associated with conditions like heart failure or kidney disease, and elevated blood pressure is not a direct complication of diabetes insipidus related to a pituitary gland tumor.
Question 2 of 9
The nurse is preparing to administer an IM dose of vitamin B1 (Thiamine) to a male client experiencing acute alcohol withdrawal and peripheral neuritis. The client belligerently states, "What do you think you're doing?" How should the nurse respond?
Correct Answer: B
Rationale: The correct response is to provide a relevant explanation to the client. Choice B, "This shot will help relieve the pain in your feet," is the best answer because it directly addresses the client's concern about the purpose of the medication. By explaining the potential benefit of the injection, the nurse can alleviate the client's anxiety and increase their cooperation during the procedure. Choice A is incorrect as it dismisses the client's question and may escalate the situation. Choice C is not suitable as it deviates from addressing the client's immediate query. Choice D is incorrect because it fails to specifically address the client's concern regarding the medication's purpose.
Question 3 of 9
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?
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.
Question 4 of 9
A 20-year-old male client is diagnosed with Ewing's sarcoma following an examination for a knee injury. Which instruction is most important for the nurse to provide the client?
Correct Answer: D
Rationale: The most crucial instruction for the nurse to provide the client is to seek treatment for the sarcoma immediately. Ewing's sarcoma is a type of cancer that necessitates prompt and aggressive treatment for the best possible outcome. While managing pain (Choice A) and monitoring swelling (Choice B) are important, addressing the underlying sarcoma is the priority. Instructing the client to avoid weight-bearing (Choice C) is not directly related to the treatment of Ewing's sarcoma and may not be the most critical instruction at this point.
Question 5 of 9
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?
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.
Question 6 of 9
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?
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.
Question 7 of 9
A client with complaints of shortness of breath and abdominal pain 1 week after bariatric surgery is admitted for follow-up evaluation. Which assessment finding warrants immediate intervention by the nurse?
Correct Answer: C
Rationale: A blood pressure of 88/50 mmHg indicates possible hypovolemia or shock, which requires immediate attention. Hypotension can be a sign of decreased perfusion to vital organs, potentially leading to organ failure. The other options, such as a rectal temperature of 101°F, complaints of left shoulder pain, or sustained sinus tachycardia, while important, do not present the same level of immediate threat to the client's well-being as a critically low blood pressure.
Question 8 of 9
Which medication should the nurse anticipate administering to a client who is diagnosed with myxedema coma?
Correct Answer: A
Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.
Question 9 of 9
What actions should the nurse take regarding an older adult male who had an abdominal cholecystectomy and has become increasingly confused and disoriented over the past 24 hours, found wandering into another client's room and returned to his own room by the unlicensed assistive personnel (UAP)? (Select all that apply)
Correct Answer: B
Rationale: In this situation, the appropriate action for the nurse to take is to report the mental status change to the healthcare provider. Confusion and disorientation post-surgery can be indicative of various factors, such as electrolyte imbalances or respiratory issues, necessitating comprehensive assessment by the healthcare team. Applying restraints and raising bed rails may not address the underlying cause of the confusion, and assigning the UAP to reassess the client's risk for falls does not directly address the cognitive changes observed.
