ATI Exit Exam 2024

Correct Answer: C

Rationale: Setting the IV pump to 125 mL/hr ensures the correct infusion rate for delivering 500 mL over 4 hours. To calculate the mL/hr rate, divide the total volume to be infused (500 mL) by the total time for infusion (4 hours): 500 mL / 4 hours = 125 mL/hr. Choice A (75 mL/hr) is too low and would result in an insufficient infusion rate, potentially delaying fluid resuscitation. Choice B (100 mL/hr) would also be too low and not deliver the fluid within the specified time frame. Choice D (150 mL/hr) is too high and would infuse the fluid too quickly, potentially causing fluid overload and complications.

Correct Answer: C

Rationale: In Cushing's disease, there is increased cortisol production, which can lead to various metabolic disturbances. One of the common findings is an increased serum potassium level. The other options are incorrect because Cushing's disease typically causes hyperglycemia, not decreased serum glucose levels (A), lymphocytopenia, not increased lymphocyte count (B), and hyponatremia, not decreased serum sodium level (D).

Correct Answer: A

Rationale: The correct answer is A: Tingling in the fingers. Tingling in the fingers is a common sign of hypocalcemia, often seen after a thyroidectomy. Hypocalcemia can occur post-thyroidectomy due to inadvertent damage or removal of the parathyroid glands which regulate calcium levels. Choices B, C, and D are incorrect. Elevated blood pressure is not typically associated with hypocalcemia. Positive Chvostek's sign is a clinical sign of hypocalcemia but is usually assessed as facial muscle twitching, not tingling in the fingers. Positive Kernig's sign is a test for meningitis, not related to hypocalcemia.

Correct Answer: B

Rationale: The correct answer is B. Food exchange lists from the American Diabetes Association are a reliable resource for meal planning in diabetes. They provide structured guidance on appropriate food choices and portion sizes. Choice A, personal blogs, may not always offer accurate and evidence-based information. Choice C, diabetes medication information from the Physicians' Desk Reference, is not directly related to meal planning. Choice D, food label recommendations from the Institute of Medicine, while important for understanding nutritional content, may not provide the structured meal planning guidance needed for a client with type 2 diabetes mellitus.

Correct Answer: A

Rationale: When mixing NPH and regular insulin in the same syringe, the nurse should first inject air into the NPH insulin vial. This action prevents contamination by allowing an easier withdrawal of the correct dose of NPH insulin after withdrawing the regular insulin. Withdrawing the prescribed dose of regular insulin (Choice B) is incorrect as it does not address the initial step of injecting air into the NPH vial. Similarly, withdrawing the prescribed dose of NPH insulin (Choice C) is incorrect as it skips the crucial first step. Mixing the two insulins in separate syringes (Choice D) is not ideal since combining them in one syringe is a common practice to reduce the number of injections for the patient.
