CAT Exam Practice Test Questions

Question 1 of 5

A heparin infusion is prescribed for a client who weighs 220 pounds. After administering a bolus dose of 80 units/kg, the nurse calculates the infusion rate for the heparin sodium at 18 units/kg/hour. The available solution is Heparin Sodium 25,000 units in 5% Dextrose Injection 250 ml. The nurse should program the infusion pump to deliver how many ml/hour?

Correct Answer: B

Rationale: To calculate the infusion rate, first, find the total dose required per hour, which is the patient's weight (220 pounds) multiplied by the prescribed rate (18 units/kg/hour). This equals 3960 units/hour. Next, determine how many ml of the solution contain 25,000 units; this is 250 ml. Divide the total dose required per hour (3960 units) by the units per ml (25,000 units/250 ml) to find how many ml are needed per hour. This results in 27 ml/hour. Therefore, the nurse should program the infusion pump to deliver 27 ml/hour. Choice A (18) is incorrect as it does not account for the concentration of the heparin solution. Choices C (36) and D (45) are incorrect as they do not reflect the accurate calculations based on the patient's weight and the heparin concentration in the solution.

Question 2 of 5

When deciding whether to join a nursing strike called after collective bargaining efforts have failed, which factor is most important for the nurse to consider?

Correct Answer: B

Rationale: The correct answer is B. The role of nurses as client advocates is crucial when considering the impact of a strike on patient care. Nurses have a responsibility to advocate for their patients' well-being at all times. Choices A, C, and D, although important, are not the most critical factor to consider in this situation. The Nurse Practice Act of the State is essential for guiding nursing practice, standards of clinical nursing practice ensure quality care, and personal values are important; however, the primary focus during a strike should be on the role of nurses as client advocates.

Question 3 of 5

When should the nurse conduct an Allen's test?

Correct Answer: C

Rationale: The correct time to conduct an Allen's test is just before arterial blood gases are drawn peripherally. This test is performed to assess the adequacy of collateral circulation in the hand before obtaining arterial blood gases. Choice A is incorrect because an Allen's test is not specifically done when obtaining pulmonary artery pressures. Choice B is incorrect because an Allen's test is not used to assess deep vein thrombosis. Choice D is incorrect because an Allen's test is not done specifically before attempting a cardiac output calculation.

Question 4 of 5

The nurse is developing a teaching plan for a client with acute gastritis caused by drinking contaminated water. The nurse should emphasize the need to report the onset of which problem?

Correct Answer: D

Rationale: The correct answer is D: Bloody emesis. Bloody emesis indicates potential bleeding or severe irritation, which should be reported immediately. In the context of acute gastritis, bloody emesis could indicate a more serious complication that requires urgent medical attention. Choices A, B, and C are not typically associated with acute gastritis caused by contaminated water and do not signal as critical of a condition as bloody emesis. Low-grade fever, bruising of the skin, and abdominal cramping are more commonly associated with other conditions or may be less urgent in this context.

Question 5 of 5

A male client with hypertension, who received new antihypertensive prescriptions at his last visit returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106 mmHg and he admits that he has not been taking the prescribed medication because the drugs make him feel bad. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?

Correct Answer: A

Rationale: The correct answer is A: Stroke secondary to hemorrhage. Hypertension increases the risk of stroke due to the stress and damage it causes to blood vessels, which can lead to hemorrhage. Choice B is incorrect because acute kidney injury is more commonly associated with chronic uncontrolled hypertension, not acute elevations. Choice C is incorrect as heart block is not a direct consequence of hypertension. Choice D is incorrect as hypertension does not directly cause cataracts leading to blindness.
