CAT Exam Practice Test
1. An older male client is admitted to the mental health unit with a sudden onset of global disorientation and is continuously conversing with his mother, who died 50 years ago. The nurse reviews the multiple prescriptions the client is currently taking and assesses his urine specimen, which is cloudy, dark yellow, and has a foul odor. These findings suggest that this client is experiencing which condition?
- A. Psychotic episode
- B. Dementia
- C. Delirium
- D. Depression
Correct answer: C
Rationale: The correct answer is C, delirium. The sudden onset of global disorientation along with cloudy, dark yellow urine with a foul odor are indicative of delirium. Delirium is an acute condition characterized by a fluctuating disturbance in awareness and cognition. In this case, the symptoms are suggestive of an underlying physiological cause, such as infection or medication side effects. Choice A, psychotic episode, is less likely as the symptoms are more in line with delirium than a primary psychotic disorder. Choice B, dementia, is a chronic and progressive condition, not typically presenting with sudden onset disorientation. Choice D, depression, does not align with the acute cognitive changes and urine abnormalities described in the scenario.
2. A female client on the mental health unit tells the nurse that her roommate is sitting on the bathroom floor with superficial cuts on her wrists. The nurse cleans and assesses the client’s wrists and asks what happened. She doesn’t respond. What should the nurse do next?
- A. Find supplies to put a dressing on the client’s wrists
- B. Take the client to a room for supervision by staff
- C. Call the healthcare provider to report the client’s behavior
- D. Go find a staff member to stay in the room with the client
Correct answer: B
Rationale: In this situation, the nurse's priority is to ensure the safety and supervision of the client. Moving the client to a room for direct supervision by staff is crucial to prevent further harm and provide immediate support. While cleaning and assessing the client's wrists are important, ensuring ongoing supervision is vital in this scenario. Calling the healthcare provider to report the behavior may be necessary but is not the immediate action required. Finding supplies to dress the client's wrists is important but not as urgent as ensuring constant supervision by staff.
3. After successful resuscitation, a client is given propranolol and transferred to the Intensive Coronary Care Unit (ICCU). On admission, magnesium sulfate 4 grams IV in 250 ml D5W at one gram/hour. Which assessment findings require immediate intervention by the nurse?
- A. Dark amber urine draining via an indwelling catheter at a rate of 40 ml per hour
- B. Serum calcium of 9.0 mg/dl (2.2 mmol/L SI) and magnesium of 1.8 mg/dl or Eq/L (0.74 mmol/L SI)
- C. Sinus rhythm at 72 beats/minute and peripheral blood pressure of 99/62
- D. Respiratory rate of 10 breaths per minute
Correct answer: D
Rationale: The correct answer is D. A low respiratory rate of 10 breaths per minute is indicative of possible magnesium toxicity, which can be a serious condition requiring immediate intervention. It is a critical finding that needs prompt attention to prevent further complications. The other options are not as urgent: A - dark amber urine may indicate dehydration but does not require immediate intervention, B - serum calcium and magnesium levels are within normal limits, C - sinus rhythm and blood pressure values are also within normal range and do not require immediate action.
4. 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.
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.
