CAT Exam Practice

HESI LPN

1. The nurse enters the room of a client who is awaiting surgery for appendicitis. The unlicensed assistive personnel (UAP) has helped the client to a position of comfort with the right leg flexed and has applied a heating pad to the clientâ€™s abdomen to relieve the clientâ€™s pain. Which action should the nurse implement first?

A. Remove the heating pad.
B. Reposition the clientâ€™s right leg.
C. Monitor for signs of inflammation.
D. Assess the clientâ€™s pain level.

Correct answer: A

Rationale: The correct action for the nurse to implement first is to remove the heating pad. Heating pads should not be used for suspected appendicitis as they can mask symptoms and potentially worsen inflammation. Choice B is not the priority as the position of comfort chosen by the UAP may be appropriate. Monitoring for signs of inflammation (Choice C) is important but not the initial action to address the immediate issue of the heating pad. Assessing the client's pain level (Choice D) can be done after removing the heating pad to evaluate the effectiveness of pain relief measures.

2. The client had gastric bypass surgery yesterday. Which intervention is most important for the nurse to implement during the first 24 postoperative hours?

A. Insert an indwelling urinary catheter
B. Monitor for the appearance of an incisional hernia
C. Instruct the client to eat small frequent meals
D. Measure hourly urinary output

Correct answer: D

Rationale: Monitoring hourly urinary output is crucial during the first 24 postoperative hours to assess kidney function, fluid balance, and early detection of complications like dehydration or inadequate kidney perfusion. Inserting an indwelling urinary catheter is not routinely necessary after gastric bypass surgery unless there are specific indications. Monitoring for an incisional hernia is important but not the highest priority in the immediate postoperative period. Instructing the client to eat small frequent meals is essential for long-term dietary management after gastric bypass surgery, but not the most critical intervention during the initial 24 hours.

3. A 3-year-old boy was successfully toilet trained prior to his admission to the hospital for injuries sustained from a fall. His parents are very concerned that the child has regressed in his toileting behaviors. Which information should the nurse provide to the parents?

A. Children usually resume their toileting behaviors when they leave the hospital
B. A retraining program will need to be initiated when the child returns home
C. Diapering will be provided since hospitalization is stressful to preschoolers
D. A potty chair should be brought from home so he can maintain his toileting skills

Correct answer: A

Rationale: Children often regress in toileting behaviors during hospitalization due to stress and changes in routine. However, they usually resume normal behaviors once they are discharged and back in their familiar environment. Providing reassurance to the parents that the child is likely to return to his previous toileting habits after leaving the hospital can help alleviate their concerns. Choices B, C, and D are incorrect because they do not address the normal pattern of behavior regression and recovery in toileting skills associated with hospitalization.

4. To differentiate adventitious lung sounds associated with heart failure from those associated with bacterial pneumonia, what information should the nurse review?

A. Sputum culture findings
B. Oxygen saturation level
C. Amount of coughing
D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Sputum culture findings. Reviewing sputum culture findings can provide valuable information to differentiate between bacterial pneumonia and heart failure, as the type of bacteria present in the sputum can help identify the specific infection. Oxygen saturation level (Choice B) is important for assessing oxygenation status but does not directly help in distinguishing between the two conditions based on lung sounds. The amount of coughing (Choice C) and respiratory rate (Choice D) may offer some clinical insights but are not as specific or diagnostic as sputum culture findings when differentiating between heart failure and bacterial pneumonia.

5. 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.
