CAT Exam Practice
1. 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?
- A. Monitor the client’s cardiac activity via telemetry.
- B. Maintain venous access with an infusion of normal saline.
- C. Assess glucose levels via finger stick every 4 to 6 hours.
- D. Evaluate hourly urine output for the return of normal renal function.
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.
2. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2 °F, and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity indicates concentrated urine, a sign of dehydration. In this scenario, the child is showing signs of dehydration with increased stool frequency, liquid consistency, fever, and vomiting. Occult blood in the stool may indicate gastrointestinal bleeding but is not a specific sign of dehydration. Abdominal distention can be seen in various conditions and is not a specific indicator of dehydration. Hyperactive bowel sounds can be present in various gastrointestinal conditions but are not directly related to dehydration.
3. A client with chronic alcoholism is admitted with a decreased serum magnesium level. Which snack option should the nurse recommend to this client?
- A. Cheddar cheese and crackers
- B. Carrot and celery sticks
- C. Beef bologna sausage slices
- D. Dry roasted almonds
Correct answer: D
Rationale: Dry roasted almonds are the most suitable snack option for a client with chronic alcoholism and a decreased serum magnesium level because they are high in magnesium. Magnesium is essential in addressing the deficiency. Cheddar cheese and crackers (Choice A) do not contain as much magnesium as almonds. Carrot and celery sticks (Choice B) are healthy choices but do not provide a significant amount of magnesium. Beef bologna sausage slices (Choice C) are not a good choice as processed meats are not rich in magnesium.
4. A client who had an intraosseous (IO) cannula placed by the healthcare provider for emergent fluid resuscitation is complaining of severe pain and numbness below the IO site. The skin around the site is pale and edematous. What action should the nurse take first?
- A. Discontinue the IO infusion
- B. Administer an analgesic via the IO site
- C. Elevate the extremity with the IO site
- D. Notify the healthcare provider
Correct answer: A
Rationale: The correct action for the nurse to take first is to discontinue the IO infusion. The client's symptoms of severe pain, numbness, pale skin, and edema below the IO site suggest a complication, such as extravasation or compartment syndrome. By discontinuing the infusion, further harm can be prevented. Administering an analgesic via the IO site or elevating the extremity would not address the underlying issue and could potentially worsen the condition. Notifying the healthcare provider can be done after stopping the infusion to seek further guidance or intervention.
5. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Review of recent laboratory test results shows that the client’s serum magnesium level has decreased below the normal range. In addition to contacting the healthcare provider, what nursing action is most important?
- A. Check the visual difficulties
- B. Note the most recent hemoglobin level
- C. Assess for hand and joint pain
- D. Observe rhythm on telemetry monitor
Correct answer: D
Rationale: The correct answer is to observe the rhythm on the telemetry monitor. Decreased magnesium levels can lead to cardiac issues, such as arrhythmias. Monitoring the heart rhythm is crucial in this situation. Checking visual difficulties (choice A) is not directly related to the potential cardiac effects of low magnesium levels. Noting the hemoglobin level (choice B) and assessing for hand and joint pain (choice C) are not the priority when dealing with low magnesium levels and possible cardiac complications.
