CAT Exam Practice Questions
Question 1 of 5
A client with leukemia who is receiving myelosuppressive chemotherapy has a platelet count of 25,000/mm3. Which intervention is most important for the nurse to include in this client's plan of care?
Correct Answer: C
Rationale: The correct answer is to assess urine and stool for occult blood. With a low platelet count, there is an increased risk of bleeding. Monitoring for occult blood is essential to detect any signs of internal bleeding. Choices A, B, and D are not the priority interventions in this situation. While monitoring for signs of activity intolerance, requiring visitors to wear respiratory masks, and obtaining the client's temperature are important aspects of care, they are not as critical as assessing for occult blood in a client with a low platelet count.
Question 2 of 5
Which type of wound would most likely require immediate intervention by the healthcare provider?
Correct Answer: A
Rationale: A laceration would most likely require immediate intervention by the healthcare provider due to its deeper tissue damage, significant bleeding, and higher risk of infection compared to abrasions, contusions, and ulcerations. Lacerations often need prompt attention to control bleeding, clean the wound, and reduce the risk of infection. Abrasions are superficial wounds that usually do not require urgent attention as they tend to heal well on their own with basic wound care. Contusions are bruises that typically resolve on their own without immediate intervention. Ulcerations are open sores that may require intervention but not necessarily immediate action unless complicated by infection or other issues.
Question 3 of 5
Which intervention should the nurse include in a long-term plan of care for a client with Chronic Obstructive Pulmonary Disease (COPD)?
Correct Answer: D
Rationale: The correct answer is D. Diaphragmatic breathing is a beneficial intervention for clients with COPD as it helps improve breathing efficiency and manage symptoms by promoting better air exchange in the lungs. It aids in achieving better exhalation, reducing air trapping, and enhancing overall lung function. Choices A, B, and C are incorrect. While reducing risk factors for infection is important for overall health, it is not a specific long-term intervention for COPD. Administering high-flow oxygen during sleep may be necessary in some cases but is not typically a long-term strategy for managing COPD. Limiting fluid intake to reduce secretions is not recommended as hydration is essential for individuals with COPD to maintain optimal respiratory function and prevent complications like mucus plugs.
Question 4 of 5
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?
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.
Question 5 of 5
A client is admitted to the intensive care unit with diabetes insipidus due to a pituitary gland tumor. Which potential complication should the nurse monitor closely?
Correct Answer: A
Rationale: The correct answer is A: Hypokalemia. In diabetes insipidus, there is excessive urination leading to fluid loss, which can result in electrolyte imbalances such as hypokalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices B, C, and D are incorrect. Ketonuria is typically seen in diabetic ketoacidosis, peripheral edema is more commonly associated with conditions like heart failure or kidney disease, and elevated blood pressure is not a direct complication of diabetes insipidus related to a pituitary gland tumor.
