ATI RN Comprehensive Exit Exam

Correct Answer: D

Rationale: The correct answer is D because a blood pressure drop or other signs of morphine overdose should be reported, especially when using a PCA pump. Choices A, B, and C are within normal limits and do not indicate an immediate concern related to morphine administration.

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: D

Rationale: The correct answer is to trim toenails straight across. This instruction is crucial for clients with diabetes to prevent ingrown toenails, which can lead to infection. Soaking feet in warm water daily can increase the risk of skin breakdown. Cotton socks are recommended, but the priority in foot care for diabetes is proper nail trimming. Using a heating pad can also pose a burn risk for individuals with reduced sensation in their feet.

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

Correct Answer: A

Rationale: The correct initial action for a patient with chest pain is to administer oxygen. Chest pain can be caused by insufficient oxygenation, and providing oxygen helps alleviate the pain by increasing oxygen levels in the blood. Administering nitroglycerin or morphine may be appropriate based on the underlying cause of the chest pain, but oxygen should be given first to ensure the patient's oxygen supply is adequate. Surgery is not typically the initial intervention for chest pain.
