CAT Exam Practice Questions
Question 1 of 5
A client has had several episodes of clear, watery diarrhea that started yesterday. What action should the nurse implement?
Correct Answer: D
Rationale: The correct action for the nurse to implement in a client experiencing clear, watery diarrhea is to review the client's current list of medications. Certain medications can cause diarrhea as a side effect, so identifying any potential culprits is essential. Administering an antiemetic (Choice A) is not appropriate for diarrhea, as antiemetics are used to control nausea and vomiting, not diarrhea. Assessing for hemorrhoids (Choice B) is not the priority when the client is experiencing watery diarrhea; addressing the root cause is crucial. Checking the client's hemoglobin level (Choice C) is not the immediate action needed for this situation as it does not directly address the cause of diarrhea.
Question 2 of 5
A client prescribed warfarin is being taught about dietary modifications by a nurse. Which statement by the client indicates understanding of the teaching?
Correct Answer: B
Rationale: The correct answer is B. Consistency in vitamin K intake is crucial for clients on warfarin to maintain stable anticoagulation levels. Option A is incorrect as vitamin C does not directly interact with warfarin. Option C is incorrect because although leafy greens are high in vitamin K, excessive consumption can affect warfarin's effectiveness. Option D is incorrect as any changes in diet, particularly in vitamin K intake, can impact the efficacy of warfarin.
Question 3 of 5
The public health nurse received funding to initiate a primary prevention program in the community. Which program best fits the nurse's proposal?
Correct Answer: C
Rationale: The correct answer is C: Vitamin supplements for high-risk pregnant women. This option aligns with primary prevention by preventing deficiencies before they occur, which is a key aspect of primary prevention. Providing vitamin supplements to high-risk pregnant women can help prevent birth defects and complications. Choices A, B, and D do not align with primary prevention strategies. Case management and screening for clients with HIV (Choice A) is more of a secondary prevention strategy aimed at early detection and management. A regional relocation center for earthquake victims (Choice B) is focused on addressing the aftermath of a disaster rather than preventing it. Lead screening for children in low-income housing (Choice D) is more about early detection and intervention rather than primary prevention.
Question 4 of 5
A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client's plan of care?
Correct Answer: A
Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client's cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
Question 5 of 5
A male client with cirrhosis has jaundice and pruritus. He tells the nurse that he has been soaking in hot baths at night with no relief of his discomfort. What action should the nurse take?
Correct Answer: D
Rationale: Cooler water and oil-based lotion can help relieve pruritus and improve comfort in clients with cirrhosis experiencing jaundice and pruritus. Hot baths can exacerbate itching, so it is important to suggest cooler showers instead. Choice A is incorrect because symptoms like pruritus can be managed. Choice B is not the most appropriate initial intervention for pruritus related to liver disease. Choice C suggests the use of calamine lotion, which may not be as effective as oil-based lotion for relieving pruritus in this case.
