ATI RN Exit Exam

Correct Answer: D

Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.

Correct Answer: C

Rationale: Suctioning the tracheostomy regularly is crucial in caring for a patient with a tracheostomy as it helps keep the airway clear of secretions, preventing blockages and potential complications. Cleaning the tracheostomy site daily is important for hygiene but not as critical as regular suctioning. Changing the tracheostomy ties daily may not be necessary unless soiled or loose. Providing humidified oxygen may be part of the care plan but is not as directly related to maintaining the tracheostomy patency as suctioning.

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: 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 to monitor potassium levels in patients receiving furosemide. Furosemide is a loop diuretic that can lead to potassium loss in the urine, potentially causing hypokalemia. Monitoring potassium levels is crucial to prevent complications associated with low potassium levels, such as cardiac arrhythmias. Monitoring sodium levels (choice B) is not typically necessary with furosemide use, as it primarily affects potassium levels. Calcium levels (choice C) and glucose levels (choice D) are not directly impacted by furosemide and require monitoring for other conditions or medications.
