CAT Exam Practice
1. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
- A. Ate an extra peanut butter sandwich before gym class
- B. Incorrectly drew up and administered too much insulin
- C. Was not hungry, so she skipped eating lunch
- D. Has had a cold and ear infection for the past two days
Correct answer: B
Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.
2. The nurse is performing a peritoneal dialysis exchange on a client with chronic kidney disease (CKD). Which assessment finding should the nurse report to the healthcare provider?
- A. The appearance of the returning dialysate fluid is cloudy
- B. The client complains of slight shortness of breath during installation
- C. The amount of the returning dialysate fluid is greater than the amount instilled
- D. The client complains of abdominal fullness and cramping during instillation
Correct answer: A
Rationale: Cloudy dialysate fluid can indicate peritonitis, a serious complication of peritoneal dialysis. Peritonitis is an urgent condition that requires immediate evaluation and treatment. Reporting this finding promptly is crucial to prevent further complications. Choices B, C, and D are not indicative of peritonitis and do not require immediate reporting to the healthcare provider. Complaining of slight shortness of breath, having a greater return volume, and experiencing abdominal fullness and cramping are common occurrences during peritoneal dialysis and do not necessarily indicate an emergent issue.
3. At 1130, the nurse assumes care of an adult client with diabetes mellitus who was admitted with an infected foot ulcer. After reviewing the client’s electronic health record, which priority nursing action should the nurse implement?
- A. Administer insulin based on the sliding scale
- B. Assess the appearance of the foot wound
- C. Obtain antibiotic peak and trough levels
- D. Initiate hourly measurements of urine output
Correct answer: B
Rationale: Assessing the appearance of the foot wound is the priority action in this scenario. This assessment is crucial to monitor for any signs of infection progression or complications related to the foot ulcer, especially in a client with diabetes mellitus. Administering insulin based on the sliding scale (Choice A) is important but not the immediate priority compared to assessing the foot wound. Obtaining antibiotic peak and trough levels (Choice C) is relevant but not as immediate as assessing the wound for signs of infection. Initiating hourly measurements of urine output (Choice D) is not the priority when compared to assessing the foot wound in a client with an infected foot ulcer.
4. A mother brings her child, who has a history of asthma, to the emergency room. The child is wheezing and speaking one word between each breath. The child is anxious, tachycardic, and has labored respirations. Which assessment is most important for the nurse to obtain?
- A. Type of inhaler the child typically uses on a regular basis
- B. Frequency of rescue inhaler use during the week
- C. Last dose and type of rescue inhaler used by the child
- D. Type of allergen exposure or trigger for the current episode
Correct answer: C
Rationale: The correct answer is C because knowing the last dose and type of rescue inhaler used helps assess if the child has received adequate treatment and if further intervention is needed. This information is crucial in managing an acute asthma exacerbation. Choice A, the type of inhaler the child typically uses, is less critical during an emergency. Choice B, the frequency of rescue inhaler use during the week, is important for general asthma management but does not provide immediate guidance in the acute situation. Choice D, the type of allergen exposure or trigger, is more relevant for preventive strategies and does not directly impact the immediate treatment of the child's acute asthma attack.
5. The unlicensed assistive personnel (UAP) reports that a client’s blood pressure cannot be measured because the client has casts on both arms and is unable to be turned to the prone position for blood pressure measurement in the legs. What action should the nurse implement?
- A. Advise the UAP to document the last blood pressure obtained on the client's graphic sheet
- B. Estimate the blood pressure by assessing the pulse volume of the client’s radial pulses
- C. Demonstrate how to palpate the popliteal pulse with the client supine and the knee flexed
- D. Document why the blood pressure cannot be accurately measured at the present time
Correct answer: D
Rationale: When a client cannot have their blood pressure measured due to specific circumstances such as casts on both arms, the nurse should document the reason why the blood pressure cannot be obtained accurately. This documentation is crucial for maintaining a clear record of the client's condition and for continuity of care. Advising the UAP to document the last blood pressure obtained (Choice A) does not address the current inability to measure the blood pressure. Estimating the blood pressure by assessing the pulse volume of radial pulses (Choice B) is not a reliable method for obtaining accurate blood pressure readings. Demonstrating how to palpate the popliteal pulse (Choice C) is irrelevant in this situation as it does not provide a solution for accurately measuring the blood pressure.
