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. The nurse is managing the care of a client with Cushing's syndrome. Which interventions should the nurse delegate to the unlicensed assistive personnel (UAP)? (Select all that apply)
- A. Evaluate the client for sleep disturbances
- B. limit client exercise
- C. Report any client complaint of pain or discomfort
- D. Note and report the client's food and liquid intake during meals and snacks
Correct answer: D
Rationale: Weighing the client and monitoring food and liquid intake are appropriate tasks to delegate to the unlicensed assistive personnel (UAP) when managing a client with Cushing's syndrome. These tasks provide essential information for evaluating the client's condition and response to treatment. Evaluating for sleep disturbances and reporting client complaints of pain or discomfort require a higher level of assessment and interpretation, which should be performed by licensed healthcare providers. Therefore, options A and C are tasks that involve assessment and interpretation beyond the scope of practice for UAP.
3. An IV antibiotic is prescribed for a client with a postoperative infection. The medication is to be administered in 4 divided doses. What schedule is best for administering this prescription?
- A. 1000, 1600, 2200, 0400
- B. Give in equally divided doses during waking hours
- C. Administer with meals and a bedtime snack
- D. 0800, 1200, 1600, 2000
Correct answer: D
Rationale: The best schedule for administering the IV antibiotic in 4 divided doses is 0800, 1200, 1600, and 2000. This timing allows for equal spacing between doses, ensuring consistent therapeutic levels of the medication in the client's system. Choice A provides doses too close together, increasing the risk of medication errors and potential toxicity. Choice B's suggestion of giving doses during waking hours is vague and lacks specific timing, which may result in irregular dosing intervals. Choice C, administering with meals and a bedtime snack, is unrelated to the timing of the antibiotic doses and does not optimize the drug's effectiveness.
4. The nurse is planning care for a family whose children did not receive childhood immunizations. After one of the children contracted mumps, the father is diagnosed with orchitis. Which intervention should be included in the father's plan of care?
- A. Use of bedrest with scrotal support
- B. Administration of antibiotics for 10 days
- C. Applying heat to promote the healing process
- D. Using an ice pack to reduce scrotal pain
Correct answer: A
Rationale: For orchitis, the recommended intervention is bedrest with scrotal support. This helps reduce swelling and discomfort in the scrotum. Antibiotics are generally not required for viral orchitis, so administering antibiotics for 10 days (Choice B) is not indicated. Applying heat (Choice C) may worsen swelling and should be avoided. Using an ice pack (Choice D) is not the preferred method for managing orchitis; it may not be as effective as providing support and rest for the scrotum.
5. Following an open reduction and internal fixation of a compound fracture of the leg, a male client complains of “a tingly sensation†in his left foot. The nurse determines the client’s left pedal pulses are diminished. Based on these findings, what is the client’s greatest risk?
- A. Reduce pulmonary ventilation and oxygenation related to fat embolism.
- B. Neurovascular and circulation compromise related to compartment syndrome.
- C. Wound infection and delayed healing due to fractured bone protrusion.
- D. Venous stasis and thrombophlebitis related to postoperative immobility.
Correct answer: B
Rationale: The correct answer is B. Compartment syndrome is a serious condition that can occur following trauma or surgery, leading to compromised neurovascular status in the affected limb. Symptoms include pain, paresthesia (tingling sensation), and diminished pulses. If left untreated, compartment syndrome can result in tissue damage and potential loss of limb function. Options A, C, and D are incorrect because they do not directly address the neurovascular compromise associated with compartment syndrome.
