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: B

Rationale: The correct answer is B. It is crucial for clients to complete the entire course of antibiotics as prescribed, even if symptoms improve. This helps to ensure that the infection is fully treated and reduces the risk of developing antibiotic resistance. Choice A is incorrect because stopping the medication when symptoms disappear can lead to incomplete treatment. Choice C is incorrect as amoxicillin can be taken with or without food. Choice D is incorrect because taking amoxicillin with milk can decrease its absorption.

Correct Answer: B

Rationale: Palpating the pulse distal to the cast is the priority as it assesses for circulation. Ensuring adequate blood flow is essential to prevent complications such as compartment syndrome. Placing an ice pack over the cast could cause constriction of blood vessels, further compromising circulation. Teaching the client about cast care and positioning the casted extremity on a pillow are important but do not take precedence over assessing circulation.

Correct Answer: D

Rationale: Elevating the client's right arm on a pillow is essential post-mastectomy to reduce swelling and promote circulation. Placing the client in the supine position may not be comfortable or ideal after a mastectomy. Encouraging the client to lift objects with the right arm can strain the surgical site and hinder healing. Measuring the client's blood pressure on the right arm should be avoided to prevent disruption to the area and inaccurate readings.

Correct Answer: A

Rationale: The correct answer is A. A lack of tear production is a sign of severe dehydration in infants, indicating the need for IV therapy. Option B, bulging fontanels, is a sign of increased intracranial pressure, not dehydration. Option C, breathing slower than normal, and Option D, decreasing heart rate, are not specific signs of severe dehydration that would indicate the need for IV therapy in this case.
