CAT Exam Practice
1. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?
- A. 12.5
- B. 5
- C. 10
- D. 20
Correct answer: B
Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.
2. After a sudden loss of consciousness, a female client is taken to the ED, and initial assessment indicates that her blood glucose level is critically low. Once her glucose level is stabilized, the client reports that she was recently diagnosed with anorexia nervosa and is being treated at an outpatient clinic. Which intervention is more important to include in this client’s discharge plan?
- A. Describe the importance of maintaining stable blood glucose levels.
- B. Encourage a balanced and nutritious diet.
- C. Reinforce the need to continue outpatient treatment.
- D. Educate on the risks of untreated anorexia nervosa.
Correct answer: C
Rationale: Continuing outpatient treatment is crucial for managing anorexia nervosa and preventing future complications. Reinforcing the need to continue outpatient treatment ensures ongoing support, monitoring, and therapy for the client's anorexia nervosa. Describing the importance of maintaining stable blood glucose levels (Choice A) is relevant but does not address the underlying eating disorder directly. Encouraging a balanced and nutritious diet (Choice B) is important; however, specific dietary recommendations should be tailored to the individual's condition by healthcare providers. Educating on the risks of untreated anorexia nervosa (Choice D) is informative but does not provide a direct actionable step for the client's immediate discharge plan, unlike the importance of continuing outpatient treatment.
3. The nurse is assessing a 3-month-old infant who had a pylorotomy yesterday. This child should be medicated for pain based on which finding?
- A. Restlessness
- B. Clenched Fist
- C. Increased pulse rate
- D. Increased respiratory rate
Correct answer: A
Rationale: In infants, restlessness can be a significant indicator of discomfort or pain, necessitating appropriate pain management. While choices B, C, and D can also be associated with pain, restlessness is a more general and reliable indicator in this scenario. A clenched fist might indicate pain or distress, but it is not as specific as restlessness in assessing pain in infants. Increased pulse rate and respiratory rate can be influenced by various factors other than pain, making them less reliable indicators of pain in this context.
4. A 10-year-old who has terminal brain cancer asks the nurse, 'What will happen to my body when I die?' How should the nurse respond?
- A. The heart will stop beating, and you will stop breathing.
- B. You will go to sleep and not wake up.
- C. Your body will stop functioning, and you will no longer feel pain.
- D. You will feel very tired, and your body will shut down slowly.
Correct answer: C
Rationale: The correct answer is C because it provides a truthful yet sensitive response to the child's question. Saying that the body will stop functioning and that there will be no more pain helps the child understand what to expect without unnecessary details or causing distress. Choice A is too technical and may not be suitable for a child. Choice B might give the impression of a peaceful passing, which may not always be the case. Choice D introduces the concept of feeling tired, which might not be accurate or helpful in this context.
5. The urinary drainage of a client with continuous bladder irrigation is becoming increasingly red. Which intervention should the nurse implement?
- A. Increase the irrigation rate
- B. Lower the head of the bed
- C. Milk the catheter tubing
- D. Evaluate for fluid overload
Correct answer: A
Rationale: Increasing the irrigation rate can help clear any blood clots and reduce the redness in the urinary drainage. This intervention aims to improve the flushing of the bladder and potentially resolve the issue. Lowering the head of the bed would not directly address the red urinary drainage. Milking the catheter tubing is not recommended as it can cause trauma to the catheter or bladder, leading to further complications. While evaluating for fluid overload is an important nursing consideration, it does not directly address the immediate concern of redness in the urinary drainage, which requires a focused intervention to clear any blockages or clots in the system.
