CAT Exam Practice Test

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.

Correct Answer: D

Rationale: Correct Answer: The best response for the nurse is to choose option D, 'I understand you are frustrated with the wait time.' This response demonstrates empathy and validates the client's feelings, helping to defuse the situation. Choice A is not the best response as it does not directly address the client's emotions or concerns. Choice B is inappropriate as it gives preferential treatment based on the client's behavior. Choice C, while true, does not acknowledge the client's frustration or offer empathy.

Correct Answer: A

Rationale: Assisting the client in identifying goals for the day is the most important aspect of the plan of care for a client with severe depression. Setting achievable daily goals helps engage the client in activities and promotes a sense of accomplishment, which can contribute to gradual improvement in their condition. Encouraging participation in team sports may be overwhelming for a client with severe depression as it requires a significant level of energy and motivation that the client may not possess at this time. Group sessions focusing on self-esteem and daily affirmations are beneficial interventions, but they may not have an immediate impact compared to setting achievable daily goals that can provide a sense of purpose and achievement for the client.

Correct Answer: C

Rationale: The correct answer is C: 'Severe mid-epigastric pain after ingesting a heavy meal.' This symptom is characteristic of acute pancreatitis due to inflammation of the pancreas, which often presents with severe pain in the mid-epigastric region that may worsen after eating. Choices A, B, and D describe symptoms that are not typically associated with acute pancreatitis. A low-grade fever and left lower abdominal pain (Choice A) may be more indicative of other conditions like diverticulitis. Severe headache and sweating (Choice B) are commonly seen in conditions like migraines or infections. Dull, continuous, right lower quadrant pain and nausea (Choice D) could be suggestive of appendicitis rather than acute pancreatitis.
