CAT Exam Practice Test

1. An adult suffered burns to the face and chest resulting from a grease fire. On admission, the client was intubated, and a 2-liter bolus of normal saline was administered IV. Currently, the normal saline is infusing at 250 ml/hour. The client’s heart rate is 120 beats/minute, blood pressure is 90/50 mmHg, respirations are 12 breaths/minute over the ventilated 12 breaths for a total of 24 breaths/minute, and the central venous pressure (CVP) is 4 mm H2O. Which intervention should the nurse implement?

A. Increase the rate of normal saline infusion
B. Infuse an additional bolus of normal saline
C. Lower the head of the bed to a recumbent position
D. Bring a tracheostomy tray to the bedside

Correct answer: B

Rationale: The correct intervention is to infuse an additional bolus of normal saline. The client's presentation with a heart rate of 120 beats/minute, hypotensive blood pressure of 90/50 mmHg, and low CVP of 4 mm H2O indicates hypovolemic shock. Administering more normal saline can help in restoring intravascular volume and improving perfusion. Increasing the rate of normal saline infusion (Choice A) is not the best choice as it may lead to fluid overload. Lowering the head of the bed to a recumbent position (Choice C) could worsen hypotension by reducing venous return. Bringing a tracheostomy tray to the bedside (Choice D) is not a priority at this time as the client is already intubated, and the immediate concern is addressing the hypovolemia.

2. A male client with diabetes mellitus takes NPH/regular 70/30 insulin before meals and azithromycin PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of azithromycin an hour before breakfast as instructed. What action should the nurse implement?

A. Provide a PRN dose of an antacid to take with the azithromycin right after breakfast
B. Offer to obtain a new breakfast tray in an hour so the client can take the azithromycin
C. Instruct the client to eat his breakfast and take the azithromycin two hours after eating
D. Tell the client to skip that day's dose and resume taking the azithromycin the next day

Correct answer: C

Rationale: Azithromycin should ideally be taken on an empty stomach; however, if taken after breakfast, it should not affect its efficacy. Instructing the client to eat his breakfast and take the azithromycin two hours after eating allows for proper absorption without compromising its effectiveness. Providing an antacid with azithromycin is not necessary in this case. Offering a new breakfast tray in an hour or skipping the dose is not the best course of action as it may lead to missed doses and potential effectiveness issues.

3. A 20-year-old male client is diagnosed with Ewing’s sarcoma following an examination for a knee injury. Which instruction is most important for the nurse to provide the client?

A. Take analgesics regularly to manage pain
B. Notify the healthcare provider if the swelling worsens
C. Avoid weight-bearing on the affected knee until the injury heals
D. Seek treatment for the sarcoma immediately

Correct answer: D

Rationale: The most crucial instruction for the nurse to provide the client is to seek treatment for the sarcoma immediately. Ewing's sarcoma is a type of cancer that necessitates prompt and aggressive treatment for the best possible outcome. While managing pain (Choice A) and monitoring swelling (Choice B) are important, addressing the underlying sarcoma is the priority. Instructing the client to avoid weight-bearing (Choice C) is not directly related to the treatment of Ewing's sarcoma and may not be the most critical instruction at this point.

4. Based on the information provided in this client’s medical record during labor, which intervention should the nurse implement?

A. Apply oxygen at 10 L per minute via mask
B. Stop the oxytocin infusion
C. Turn the client to the right lateral position
D. Continue monitoring the progress of labor

Correct answer: C

Rationale: Turning the client to the right lateral position is essential as it can improve fetal oxygenation and uterine blood flow, promoting better labor outcomes. This intervention helps relieve pressure on blood vessels, enhancing blood flow to the placenta and improving oxygen supply to the fetus. Applying oxygen at a specific rate may not address the underlying issue of compromised blood flow and oxygenation. Stopping the oxytocin infusion is not the priority unless medically indicated as it can affect labor progression. While monitoring the progress of labor is important, actively addressing the compromised fetal oxygenation and uterine blood flow by changing the client's position takes precedence in this scenario.

5. Three hours following a right carotid endarterectomy, the nurse notes a moderate amount of bloody drainage on the client’s dressing. Which additional assessment finding warrants immediate intervention by the nurse?

A. Sore throat when swallowing
B. Tongue deviation to the left
C. Palpable temporal pulses
D. Temperature of 99.2°F (37.3°C)

Correct answer: B

Rationale: Tongue deviation to the left is the correct answer. It could indicate a complication such as nerve injury or hematoma, which requires immediate attention. A sore throat when swallowing may be expected postoperatively but does not indicate an immediate complication. Palpable temporal pulses are a normal finding and do not require immediate intervention. A temperature of 99.2°F (37.3°C) is slightly elevated but does not suggest a critical issue related to the surgery.
