CAT Exam Practice
1. The nurse enters the room of a client who is awaiting surgery for appendicitis. The unlicensed assistive personnel (UAP) has helped the client to a position of comfort with the right leg flexed and has applied a heating pad to the client’s abdomen to relieve the client’s pain. Which action should the nurse implement first?
- A. Remove the heating pad.
- B. Reposition the client’s right leg.
- C. Monitor for signs of inflammation.
- D. Assess the client’s pain level.
Correct answer: A
Rationale: The correct action for the nurse to implement first is to remove the heating pad. Heating pads should not be used for suspected appendicitis as they can mask symptoms and potentially worsen inflammation. Choice B is not the priority as the position of comfort chosen by the UAP may be appropriate. Monitoring for signs of inflammation (Choice C) is important but not the initial action to address the immediate issue of the heating pad. Assessing the client's pain level (Choice D) can be done after removing the heating pad to evaluate the effectiveness of pain relief measures.
2. The practical nurse (PN) is assigned to work with three registered nurses (RN) who are caring for neurologically compromised clients. The client with which change in status is best to assign to the PN?
- A. Diabetic ketoacidosis whose Glasgow Coma Scale score changed from 10 to 7
- B. Subdural hematoma whose blood pressure changed from 150/80 mmHg to 170/60 mmHg
- C. Myxedema coma whose blood pressure changed from 80/50 mmHg to 70/40 mmHg
- D. Viral meningitis whose temperature changed from 101° F (38.3 C) to 102° F (38.9C)
Correct answer: D
Rationale: The correct answer is D because viral meningitis with a slight increase in temperature is less acute and complex compared to the other conditions. This change in temperature does not indicate a critical or urgent situation requiring immediate attention or intervention beyond the scope of a practical nurse. Choices A, B, and C present more significant changes in health status such as a decrease in Glasgow Coma Scale score, an increase in intracranial pressure indicated by blood pressure changes, and a significant drop in blood pressure, respectively. These changes require closer monitoring and intervention by registered nurses due to the higher acuity and complexity of care needed for these conditions.
3. Two weeks following a Billroth II (gastrojejunostomy), a client develops nausea, diarrhea, and diaphoresis after every meal. When the nurse develops a teaching plan for this client, which expected outcome statement is the most relevant?
- A. Describes a schedule for antacid use in combination with other prescribed medications
- B. Selects a pattern of small meals interspersed with fluid intake
- C. Commits to engaging in a variety of stress reduction techniques
- D. Expresses a commitment to decrease nicotine intake
Correct answer: B
Rationale: The symptoms described are indicative of dumping syndrome, a common complication following a Billroth II procedure. Dumping syndrome presents with symptoms such as nausea, diarrhea, and diaphoresis after meals. To manage these symptoms effectively, the client should opt for small, frequent meals and avoid consuming fluids along with meals. Choice A is inaccurate because antacid use does not directly address the symptoms of dumping syndrome. Choice C is irrelevant as stress reduction techniques are not the primary intervention for dumping syndrome. Choice D is unrelated to the symptoms experienced by the client, making it an inappropriate choice.
4. An adolescent male client is admitted to the hospital. Based on Erikson’s theory of psychosocial development, which nursing intervention best assists this adolescent’s adjustment to his hospital stay?
- A. Invite him to participate in the evening group activity
- B. Schedule frequent private phone calls to his parents
- C. Provide access to a variety of video games in his room
- D. Encourage him to learn his way around the hospital
Correct answer: A
Rationale: Inviting the adolescent to participate in group activities aligns with Erikson's theory of psychosocial development, specifically the stage of developing social relationships. By engaging in group activities, the adolescent can interact with peers, fostering social skills and aiding in adjustment to the hospital environment. Choice B is incorrect as excessive reliance on phone calls to parents may hinder the adolescent's autonomy and independence, which are crucial aspects of Erikson's theory for this age group. Choice C, providing access to video games, while potentially offering entertainment, does not directly address the need for social interaction and relationship-building. Choice D, encouraging the adolescent to learn his way around the hospital, is important for familiarity but may not directly address the need for social interaction and adjustment in the hospital setting.
5. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse’s decision to hold the client’s scheduled antihypertensive medication?
- A. Increased urinary clearance of the multiple medications has led to diuresis and lowered the blood pressure.
- B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness.
- C. The additive effect of multiple medications has caused the blood pressure to drop too low.
- D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.
Correct answer: C
Rationale: The correct answer is C. When a client experiences syncope due to a significant drop in blood pressure after receiving multiple antihypertensive medications, the additive effect of these medications can cause the blood pressure to drop excessively. This additive effect can lead to hypotension, which is why the nurse decided to hold the client's scheduled antihypertensive medication. Choices A, B, and D provide incorrect rationales. Choice A mentions diuresis, which is not directly related to the drop in blood pressure due to additive medication effects. Choice B refers to an antagonistic interaction reducing effectiveness, which is not applicable in this scenario. Choice D talks about a synergistic effect leading to drug toxicity, which is not the cause of the sudden drop in blood pressure observed in the client.
