CAT Exam Practice Test

Correct Answer: A

Rationale: The most appropriate response by the nurse in this situation is to reassure the spouse that the client will be well cared for and provide information about the facility's care practices. This response not only addresses the spouse's concerns directly but also helps in building trust and confidence in the care provided. Choice B is not ideal as it may cause unnecessary worry about the fluctuating care levels. Choice C puts the responsibility on the spouse to monitor care, which may not always be feasible or appropriate. Choice D deflects the concern to other family members instead of addressing the spouse's worries directly.

Correct Answer: D

Rationale: The correct answer is D. Uremic frost is a condition in which urea and other waste products are excreted through the skin, leaving a powdery residue. This indicates poor hygiene and self-care, common issues in patients with CKD and renal osteodystrophy. Proper hygiene measures are essential to prevent complications. Choices A, B, and C are less likely to be included in the plan of care for a CKD patient with renal osteodystrophy. Choice A is more related to a vascular access issue, choice B is more related to mobility concerns, and choice C is more related to dietary education.

Correct Answer: C

Rationale: The correct answer is C: 'Severe mid-epigastric pain after ingesting a heavy meal.' This symptom is characteristic of acute pancreatitis due to inflammation of the pancreas, which often presents with severe pain in the mid-epigastric region that may worsen after eating. Choices A, B, and D describe symptoms that are not typically associated with acute pancreatitis. A low-grade fever and left lower abdominal pain (Choice A) may be more indicative of other conditions like diverticulitis. Severe headache and sweating (Choice B) are commonly seen in conditions like migraines or infections. Dull, continuous, right lower quadrant pain and nausea (Choice D) could be suggestive of appendicitis rather than acute pancreatitis.

Correct Answer: C

Rationale: Reviewing the glycosylated hemoglobin level after a few months is the best approach to evaluate the effectiveness of teaching self-injection. This measurement provides an objective indicator of the adolescent's glucose control over time, reflecting the impact of insulin self-administration education. Choices A, B, and D do not directly assess the long-term impact of the teaching on the adolescent's diabetes management.

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.
