CAT Exam Practice Test
1. Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?
- A. Neutrophils
- B. Lymphocytes
- C. Eosinophils
- D. Monocytes
Correct answer: C
Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (Choice A) are mainly involved in fighting bacterial infections. Lymphocytes (Choice B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (Choice D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.
2. When a UAP reports to the charge nurse that a client has a weak pulse with a rate of 44 beats per minute, what action should the charge nurse implement?
- A. Instruct the UAP to count the client's apical pulse rate for sixty seconds.
- B. Determine if the UAP also measured the client's capillary refill time.
- C. Assign a practical nurse (LPN) to determine if an apical radial pulse deficit is present.
- D. Notify the health care provider of the abnormal pulse rate and pulse volume.
Correct answer: D
Rationale: The correct action for the charge nurse to implement is to notify the health care provider of the abnormal pulse rate and pulse volume. A weak pulse with bradycardia (pulse rate of 44 beats per minute) requires immediate follow-up to investigate potential underlying issues. In this situation, it is crucial to involve the healthcare provider for further assessment and intervention. Instructing the UAP to count the client's apical pulse rate for sixty seconds (Choice A) may delay necessary actions. Determining capillary refill time (Choice B) is not directly related to addressing a weak pulse, and assigning an LPN to assess an apical radial pulse deficit (Choice C) is not as urgent as involving the healthcare provider.
3. An older female client living in a low-income apartment complex tells the home health nurse that she is concerned about her 81-year-old neighbor, a widow whose son recently assumed her financial affairs. Lately, her neighbor has become reclusive but is occasionally seen walking outside wearing only a robe and slippers. What response should the nurse offer?
- A. Explain that it is not unusual for older adults to suffer from dementia, which often causes such behaviors.
- B. Tell the client to talk to a healthcare provider before reporting suspicion of neglect to the authorities.
- C. Provide the number for Adult Protective Services so the client can report any suspicion of elder abuse.
- D. Encourage the client to avoid becoming involved in the neighbor’s problems for one’s protection.
Correct answer: C
Rationale: The correct response is to provide the number for Adult Protective Services so the client can report any suspicion of elder abuse. This action allows for an official investigation into possible elder abuse or neglect, ensuring the neighbor’s safety and well-being. Choice A is incorrect because assuming dementia without evidence is premature and could lead to overlooking potential abuse. Choice B is incorrect as the situation raises concerns about possible neglect or abuse, which should be reported promptly to the appropriate authorities. Choice D is incorrect as it dismisses the importance of ensuring the safety and well-being of the neighbor in need.
4. The nurse receives change of shift report on a group of clients for the upcoming shift. A client with which condition requires the most immediate attention by the nurse?
- A. Gunshot wound three hours ago with dark drainage of 2 cm on the dressing
- B. Mastectomy 2 days ago with 50 ml bloody drainage in the Jackson-Pratt drain
- C. Collapsed lung after a fall 8 hours ago with 100 ml blood in the chest tube collection container
- D. Abdominal-perineal resection 2 days ago with no drainage on dressing and fever and chills
Correct answer: C
Rationale: A collapsed lung with significant blood accumulation requires immediate attention to prevent respiratory compromise. Option A may also require attention, but the immediate threat to airway and breathing in option C takes precedence over the others. Option B has expected drainage after a mastectomy, and option D's fever and chills, while concerning, do not pose an immediate life-threatening risk as in option C.
5. When administering ceftriaxone sodium intravenously to a client before surgery, which assessment finding requires the most immediate intervention by the nurse?
- A. Headache
- B. Pruritus
- C. Nausea
- D. Stridor
Correct answer: D
Rationale: Stridor is a high-pitched, noisy breathing sound that can indicate a serious condition like airway obstruction or a severe allergic reaction, necessitating immediate intervention to maintain the client's airway and prevent further complications. While headache, pruritus, and nausea are important to assess and manage, they are not as immediately life-threatening as stridor, which requires prompt attention to prevent respiratory compromise.
