ATI RN Comprehensive Exit Exam

Correct Answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

Correct Answer: C

Rationale: The correct answer is C. Doxazosin can cause orthostatic hypotension, leading to dizziness and falls if the client rises quickly from a seated position. Instructing the client to rise slowly when sitting up from bed helps prevent these adverse effects. Choices A, B, and D are incorrect because doxazosin does not directly relate to caloric intake, dietary fiber, or a specific time of day for administration.

Correct Answer: A

Rationale: Encouraging compliance through education is crucial in helping patients understand the importance of consistent medication use. By providing education, the patient can make informed decisions about their health and better manage their condition. Contacting the healthcare provider (choice B) may be necessary in some cases, but the initial approach should focus on patient education. Documenting the refusal (choice C) is important for legal and medical records but does not address the root cause of non-compliance. Exploring alternative treatment options (choice D) should come after efforts to educate and encourage compliance with the current medication regimen.

Correct Answer: D

Rationale: The correct action for a client 1 day postoperative following a total knee arthroplasty is to apply ice packs to the affected knee. Ice packs help reduce swelling and pain in such clients. Administering aspirin is contraindicated due to the risk of bleeding postoperatively. Keeping the affected leg in a dependent position can impair circulation and increase the risk of complications. Flexing the affected knee for extended periods can strain the surgical site and hinder the healing process.

Correct Answer: B

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A is incorrect because furosemide is usually taken on an empty stomach. Choice C is unrelated to furosemide therapy. Choice D is incorrect as there is no need to limit calcium-rich foods while taking furosemide.
