CAT Exam Practice Test
1. To manage the client’s constipation, which suggestions should the nurse provide? (Select all that apply)
- A. Decrease laxative use to every other day and use oil retention enemas as needed.
- B. Include oatmeal with stewed prunes for breakfast as often as possible.
- C. Increase fluid intake by keeping a water glass next to the recliner.
- D. Recommend seeking help with regular shopping and meal preparation.
Correct answer: C
Rationale: The correct answer is C. Increasing fluid intake is essential for managing constipation. Adequate hydration helps soften stool and promotes bowel movements. Choices A and B are incorrect as decreasing laxative use without medical advice and suggesting specific foods like oatmeal with stewed prunes may not be suitable for every individual with constipation. Choice D is also incorrect as while seeking help with meal preparation can indirectly aid in managing constipation, the immediate need is to increase fluid intake.
2. A client has a history of vasovagal attacks resulting in brady-dysrhythmias. Which instruction is most important to include in the teaching plan?
- A. Use stool softeners regularly
- B. Avoid electromagnetic fields
- C. Maintain a low-fat diet
- D. Do not use aspirin products
Correct answer: A
Rationale: The correct answer is A: 'Use stool softeners regularly.' Vasovagal attacks can be triggered by straining, and using stool softeners can help prevent such attacks. Choices B, C, and D are not directly related to preventing vasovagal attacks in this context. Avoiding electromagnetic fields, maintaining a low-fat diet, or not using aspirin products are important for various health reasons but not specifically for preventing vasovagal attacks related to brady-dysrhythmias.
3. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?
- A. 7
- B. 10
- C. 14
- D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.
Correct answer: D
Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.
4. 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.
5. The public health nurse received funding to initiate a primary prevention program in the community. Which program best fits the nurse’s proposal?
- A. Case management and screening for clients with HIV.
- B. Regional relocation center for earthquake victims.
- C. Vitamin supplements for high-risk pregnant women.
- D. Lead screening for children in low-income housing.
Correct answer: C
Rationale: The correct answer is C: Vitamin supplements for high-risk pregnant women. This option aligns with primary prevention by preventing deficiencies before they occur, which is a key aspect of primary prevention. Providing vitamin supplements to high-risk pregnant women can help prevent birth defects and complications. Choices A, B, and D do not align with primary prevention strategies. Case management and screening for clients with HIV (Choice A) is more of a secondary prevention strategy aimed at early detection and management. A regional relocation center for earthquake victims (Choice B) is focused on addressing the aftermath of a disaster rather than preventing it. Lead screening for children in low-income housing (Choice D) is more about early detection and intervention rather than primary prevention.
