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. After undergoing an uncomplicated gastric bypass surgery, a client is experiencing difficulty managing their diet. What dietary instruction is most important for the nurse to explain to the client?
- A. Chew food slowly and thoroughly before attempting to swallow
- B. Plan volume-controlled evenly spaced meals throughout the day
- C. Sip fluid slowly with each meal and between meals
- D. Eliminate or reduce intake of fatty and gas-forming foods
Correct answer: A
Rationale: The correct answer is A. Thoroughly chewing food is crucial for clients who have undergone gastric bypass surgery to aid in digestion and prevent complications. Proper chewing helps break down food into smaller particles, making it easier for the digestive system to process. This instruction is essential to prevent issues such as food blockages or inadequate nutrient absorption. Choices B and C are also important for post-gastric bypass clients to maintain proper nutrition and hydration, but they are not as critical as ensuring thorough chewing. Choice D addresses dietary concerns but is not as immediately crucial as ensuring the client chews food properly to support digestion and prevent complications.
3. The nurse is completing a neurological assessment on a client with a closed head injury. The Glasgow Coma Scale (GCS) score was 13 on admission. It is now assessed at 6. What is the priority nursing intervention based on the client’s current GCS?
- A. Notify the healthcare provider of the GCS score
- B. Prepare the family for the client’s imminent death
- C. Monitor the client q1 hour for changes in the GCS score
- D. Begin cardiopulmonary resuscitation (CPR)
Correct answer: A
Rationale: A significant drop in GCS indicates a severe decline in neurological status, necessitating immediate communication with the healthcare provider. Notifying the healthcare provider allows for prompt evaluation and intervention to address the worsening condition. Choice B is incorrect because preparing the family for imminent death is premature and not supported by the information provided. Choice C is incorrect as the frequency of monitoring should be increased to every 15 minutes rather than every hour due to the significant drop in GCS. Choice D is incorrect because initiating CPR is not indicated based solely on a decreased GCS score.
4. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, “Amoxicillin (Amoxil) suspension 200 mg/5 ml.” How many ml should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
- A. 12.5
- B. 7.5
- C. 10.0
- D. 15.0
Correct answer: A
Rationale: To calculate the amount in ml that the nurse should administer every 8 hours, first, determine the amount of amoxicillin needed per dose. 1.5 grams daily divided by 3 doses equals 0.5 grams per dose. Since 0.5 grams is equivalent to 500 mg (1 gram = 1000 mg), and each 5 ml of the suspension contains 200 mg of amoxicillin, the nurse needs to administer (500 mg / 200 mg) * 5 ml = 12.5 ml every 8 hours. Therefore, the correct answer is 12.5 ml. Choices B, C, and D are incorrect because they do not reflect the accurate calculation based on the provided information.
5. A client with major depression who is taking fluoxetine calls the psychiatric clinic reporting being more agitated, irritable, and anxious than usual. Which intervention should the nurse implement?
- A. Tell the client to have a complete blood count (CBC) drawn
- B. Instruct the client to seek medical attention immediately
- C. Encourage them to take the medication at night with a snack
- D. Explain that these are common side effects of the medication
Correct answer: B
Rationale: Increased agitation, irritability, and anxiety can be signs of serotonin syndrome or other serious side effects, not common side effects of fluoxetine. Instructing the client to seek medical attention immediately is crucial to address any potential serious adverse reactions. Option A is unnecessary as a CBC would not address the symptoms described. Option C is not the priority when serious side effects are suspected. Option D is incorrect as these symptoms should not be dismissed as common side effects.
