ATI RN Exit Exam

Correct Answer: C

Rationale: A serum potassium level of 3.2 mEq/L indicates hypokalemia, a complication that should be reported in clients receiving TPN. Hypokalemia can lead to serious cardiac and neuromuscular complications. The other options are within normal ranges and do not indicate immediate concerns for a client receiving TPN. A blood glucose level of 130 mg/dL, serum sodium level of 140 mEq/L, and platelet count of 250,000/mm� are all considered normal values and do not require immediate intervention.

Correct Answer: C

Rationale: When a patient is receiving IV potassium, it is crucial to monitor the IV site. Potassium can be irritating to the veins and may cause phlebitis or infiltration. Monitoring the IV site allows early detection of any potential complications. Checking urine output (Choice A) is important to assess kidney function but is not directly related to monitoring IV potassium. Blood pressure (Choice B) and respiratory rate (Choice D) are essential vital signs to monitor in general patient care but are not specific to monitoring IV potassium administration.

Correct Answer: B

Rationale: The correct answer is B. Instructing the client to hold their breath for 10 seconds after inhaling the medication allows it to reach deeper into the lungs for maximum effectiveness. Choice A is incorrect because taking one puff every 5 minutes may lead to overuse of the medication. Choice C is incorrect as shaking the inhaler for only 2 seconds may not provide adequate mixing of the medication. Choice D is incorrect because exhaling forcefully after each puff may reduce the amount of medication that reaches the lungs.

Correct Answer: A

Rationale: The correct answer is A: Perform weight-bearing exercises. Weight-bearing exercises are crucial for preventing bone density loss in clients with osteoporosis. These exercises help strengthen bones and reduce the risk of fractures. Option B, avoiding crossing the legs beyond the midline, is not directly related to preventing injury in osteoporosis. Option C, avoiding sitting in one position for prolonged periods, is important for preventing pressure ulcers but does not specifically address preventing injury in osteoporosis. Option D, splinting the affected area, is not a standard recommendation for preventing injury in osteoporosis.

Correct Answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.
