CAT Exam Practice Test

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: A

Rationale: In emergency situations where AB negative blood is unavailable, type A negative blood can be transfused to a patient with AB negative blood type. Type A negative blood is compatible with AB negative blood, making it a suitable option until the correct blood type becomes available. Transfusion of Type A negative blood is crucial to address the severe anemia promptly. Rechecking the client's hemoglobin, blood type, and Rh factor (Choice B) may delay necessary treatment. Administering normal saline solution (Choice C) is not a substitute for blood transfusion in cases of severe anemia. Obtaining additional consent for the administration of type A negative blood (Choice D) is unnecessary as the situation is emergent and the blood type is compatible.

Correct Answer: A

Rationale: The most important action for the nurse to take when the bubbling in the water-seal chamber of the right chest tube stops is to check the chest tube connections to the water-seal container. This is crucial to ensure there are no disconnections or leaks affecting the bubbling. Replacing the water-seal collection container (choice B) is not necessary unless there is a malfunction; increasing suction (choice C) without assessing the connections can be harmful, and 'milking' the tubing (choice D) is an inappropriate action that can cause damage to the system.

Correct Answer: B

Rationale: An elevated creatinine level indicates possible renal impairment, which requires intervention. High creatinine levels are associated with decreased kidney function, and in this case, it suggests potential renal issues due to long-term corticosteroid therapy. Monitoring renal function is crucial in clients with osteoporosis on corticosteroid therapy to prevent further complications. Total calcium levels within the normal range are suitable for a client with osteoporosis receiving calcium carbonate. Phosphate and fasting glucose levels do not directly indicate renal impairment in this scenario.

Correct Answer: D

Rationale: Placing ID bands on the infant and mother is crucial to ensure correct identification and prevent mix-ups. This step is essential for maintaining proper identification of the newborn and the mother, facilitating safe care delivery. Before leaving the delivery room, ensuring proper identification is a priority to prevent any errors. Obtaining the infant's vital signs may be important but does not take precedence over ensuring correct identification. Observing the infant latching onto the breast is crucial for breastfeeding initiation but can be done after proper identification. Administering a vitamin K injection is also important but should not delay the immediate identification process.
