CAT Exam Practice Test

1. 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.

2. 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.

3. After a motor vehicle collision, a client is admitted to the medical unit with acute adrenal insufficiency (Addisonian crisis). Which prescription should the nurse implement?

Correct answer: C

Rationale: In a client with acute adrenal insufficiency (Addisonian crisis) following a motor vehicle collision, the priority intervention is to administer IV corticosteroid replacement. This is crucial to manage the crisis by replacing the deficient cortisol. Determining serum glucose levels (Choice A) may be important but is not the immediate priority in this situation. Withholding potassium additives to IV fluids (Choice B) is not indicated and may exacerbate electrolyte imbalances. Initiating IV vasopressors (Choice D) is not the primary treatment for acute adrenal insufficiency and should be reserved for managing hypotension that is unresponsive to corticosteroid therapy.

4. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, “I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home”. What response is best for the nurse to provide?

Correct answer: A

Rationale: The correct response is A: 'Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely.' Heparin is an anticoagulant that prevents further clot formation, but it does not quickly dissolve existing clots. It is crucial for the nurse to educate the client about the purpose of heparin and the necessity for close monitoring of bleeding risks. Choice B is incorrect as it does not address the misunderstanding about heparin's mechanism of action. Choice C is incorrect as home administration of IV heparin therapy requires careful consideration and should not be suggested without a thorough assessment. Choice D is incorrect as it does not address the client's misconception about heparin's role in dissolving clots and instead focuses on the client's desire to leave the hospital.

5. A client recovering from abdominal surgery is on a clear liquid diet. The nurse should identify which of the following as the most appropriate food choice for this diet?

Correct answer: B

Rationale: Grape juice is the most appropriate choice for a clear liquid diet as it is a transparent fluid that is easily digested. Clear liquid diets aim to provide fluids and electrolytes while being easy on the digestive system. Choices A, C, and D are not suitable for a clear liquid diet as they are not in liquid form or do not meet the criteria of being easily digestible for someone recovering from abdominal surgery. Chicken noodle soup, cream of wheat, and vanilla pudding are not considered clear liquids and may not be well-tolerated by a client who has undergone abdominal surgery.
