CAT Exam Practice Test
1. A 70-year-old client is admitted to the hospital after 24 hours of acute diarrhea. To determine fluid status, which initial data is most important for the nurse to obtain?
- A. Usual and current weight
- B. Color and amount of urine
- C. Number and frequency of stools
- D. Intake and output 24 hours prior to admission
Correct answer: A
Rationale: The correct answer is A: Usual and current weight. Weight changes are the most direct indicator of fluid status in a patient with acute diarrhea. Monitoring weight loss or gain can provide crucial information about fluid balance. Option B, color and amount of urine, though important for assessing renal function, is not as direct an indicator of fluid status as weight. Option C, number and frequency of stools, is relevant for assessing the severity of diarrhea but does not provide direct information on fluid status. Option D, intake and output 24 hours prior to admission, does not reflect the current fluid status and may not be accurate in a rapidly changing condition like acute diarrhea.
2. Which intervention should the nurse include in the plan of care for a patient with tetanus?
- A. Open window shades to provide natural light
- B. Encourage coughing and deep breathing
- C. Minimize the amount of stimuli in the room
- D. Reposition from side to side every hour
Correct answer: C
Rationale: The correct intervention for a patient with tetanus is to minimize the amount of stimuli in the room. Tetanus can lead to muscle spasms and heightened sensitivity to stimuli, making it essential to reduce environmental triggers for the patient's comfort and safety. Opening window shades for natural light (Choice A) may exacerbate sensitivity to light and worsen symptoms. Encouraging coughing and deep breathing (Choice B) is not directly related to managing tetanus symptoms. While repositioning the patient every hour (Choice D) is important for preventing pressure ulcers, it is not the priority when managing tetanus, which requires a quiet, low-stimulus environment to minimize muscle spasms and discomfort.
3. The nurse should explain to a client with lung cancer that pleurodesis is performed to achieve which expected outcome?
- A. Debulk tumor to maintain patency of air passages
- B. Relieve empyema after pneumonectomy
- C. Prevent the formation of effusion fluid
- D. Remove fluid from the intrapleural space
Correct answer: C
Rationale: The correct answer is C. Pleurodesis is a procedure used to prevent the re-accumulation of pleural effusion by creating adhesion between the pleurae. This helps prevent the formation of effusion fluid. Choices A, B, and D are incorrect because pleurodesis is not performed to debulk tumors, relieve empyema after pneumonectomy, or remove fluid from the intrapleural space. Understanding the purpose of pleurodesis is essential in providing accurate patient education and care.
4. 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.
5. A female client has been taking a high dose of prednisone, a corticosteroid, for several months. After stopping the medication abruptly, the client reports feeling very tired. Which nursing intervention is most important for the nurse to implement?
- A. Measure vital signs
- B. Auscultate breath sounds
- C. Palpate the abdomen
- D. Observe the skin for bruising
Correct answer: A
Rationale: Discontinuing prednisone abruptly can lead to adrenal insufficiency, which may result in symptoms such as fatigue. Monitoring vital signs is crucial in this situation to assess for potential complications like hypotension, which can be a sign of adrenal insufficiency. Auscultating breath sounds (choice B) is important but not the priority when considering the risk of adrenal insufficiency. Palpating the abdomen (choice C) and observing the skin for bruising (choice D) are not directly related to the potential complications of abruptly stopping prednisone.
