CAT Exam Practice Questions
Question 1 of 5
The nurse is assessing a client with Addison's disease who is weak, dizzy, disoriented, and has dry oral mucous membranes, poor skin turgor, and sunken eyes. Vital signs are blood pressure 94/44, heart rate 123 beats/minute, respiration 22 breaths/minute. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: The client's symptoms suggest possible adrenal crisis or hypoglycemia. Checking glucose is a priority to rule out hypoglycemia, which requires immediate intervention. The client is presenting with symptoms indicative of hypoglycemia, which can be life-threatening if not promptly addressed. Assessing extremity strength, reporting sodium levels, or measuring the cardiac QRS complex are not the most urgent actions in this scenario.
Question 2 of 5
Which medication should the nurse anticipate administering to a client who is diagnosed with myxedema coma?
Correct Answer: A
Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.
Question 3 of 5
A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
Correct Answer: B
Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.
Question 4 of 5
A male client with diabetes mellitus takes NPH/regular 70/30 insulin before meals and azithromycin PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of azithromycin an hour before breakfast as instructed. What action should the nurse implement?
Correct Answer: C
Rationale: Azithromycin should ideally be taken on an empty stomach; however, if taken after breakfast, it should not affect its efficacy. Instructing the client to eat his breakfast and take the azithromycin two hours after eating allows for proper absorption without compromising its effectiveness. Providing an antacid with azithromycin is not necessary in this case. Offering a new breakfast tray in an hour or skipping the dose is not the best course of action as it may lead to missed doses and potential effectiveness issues.
Question 5 of 5
The nurse instructs an unlicensed assistive personnel (UAP) to turn an immobilized elderly client with an indwelling urinary catheter every two hours. What additional action should the nurse instruct the UAP to take each time the client is turned?
Correct Answer: A
Rationale: The correct additional action the nurse should instruct the UAP to take each time the immobilized elderly client with an indwelling urinary catheter is turned is to empty the urinary drainage bag. This action helps to prevent backflow of urine, reduces the risk of infection, and prevents bladder distention, which are crucial for the client's comfort and health. Choices B, C, and D are incorrect as they are not directly related to the care of a client with an indwelling urinary catheter. Feeding a snack, offering oral fluids, or assessing breath sounds are important aspects of care but not the immediate action needed when turning a client with an indwelling urinary catheter to prevent complications.
