ATI RN Exit Exam

Correct Answer: B

Rationale: Placing the client in a private room is the appropriate infection control measure for C. difficile to prevent the spread of infection. While wearing a face shield may be necessary for procedures that generate splashes or sprays, it is not the primary precaution for C. difficile. Negative pressure rooms are typically used for airborne infections, not for C. difficile. Using an alcohol-based hand rub is important for hand hygiene but is not specific to managing C. difficile infection.

Correct Answer: A

Rationale: Administering oxygen is the most appropriate initial response to a patient experiencing confusion after surgery. Confusion can be a sign of hypoxia, which is inadequate oxygen supply to the brain. Administering oxygen helps ensure that the patient is getting enough oxygen, addressing a potential cause of the confusion. Repositioning the patient, encouraging deep breathing exercises, or performing a neurological exam may be necessary depending on the situation, but addressing potential hypoxia should be the priority in a confused post-operative patient.

Correct Answer: A

Rationale: The correct answer is A: Monitor daily weight. Daily weight monitoring is the most accurate method to assess fluid overload in patients with heart failure. Changes in weight can indicate fluid retention before visible signs like jugular vein distention or pitting edema appear. Checking for jugular vein distention (choice B) is helpful but may not be as sensitive as daily weight monitoring. Pitting edema (choice C) and fluid retention (choice D) are signs of fluid overload, but daily weight monitoring is a more proactive approach to detect changes early.

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.

Correct Answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.
