ATI NCLEX-RN COMPREHENSIVE TEST EXAM 1 LATEST 2025/2026 STUDY QUESTIONS AND CORRECT ANSWERS WITH RATIONALES
1. The nurse is caring for a 65-year-old male client with a history of ischemic heart disease who
has been admitted to the ICU following a myocardial infarction. The client is currently receiving
lidocaine I.V. to manage his ventricular ectopy, which has been persistent. Which of the
following factors would be most important for the nurse to consider in relation to the
administration of this medication?
o A. Decrease in arterial oxygen saturation (SaO2) when measured with a
pulse oximeter
o B. Increase in systemic blood pressure
o C. Presence of premature ventricular contractions (PVCs) on a cardiac
monitor
o D. Increase in intracranial pressure (ICP)
o E. A drop in serum potassium levels as indicated in the latest lab results
o F. Observation of a widening QRS complex on the ECG
Correct Answer: C. Presence of premature ventricular contractions (PVCs) on a cardiac
monitor.
In the context of acute myocardial infarction, the priority is to manage life-threatening
arrhythmias. Lidocaine is specifically indicated for the treatment of ventricular arrhythmias, such
as PVCs, which can be indicative of an increased risk for more serious arrhythmias like
ventricular tachycardia or ventricular fibrillation. The presence of PVCs on a cardiac monitor
would be the most immediate concern that lidocaine can address in this scenario. While the other
factors listed are important to monitor, they are not the primary indications for lidocaine
administration in the context of arrhythmia management.
2. A 72-year-old male patient with a history of atrial fibrillation and controlled hypertension has
been initiated on warfarin therapy. Upon assessment of the patient’s history, it was revealed that
he has a history of peptic ulcer. This patient also has a recent history of a peptic ulcer. Given the
client’s medical history and current medication regimen, which of the following instructions
should the nurse prioritize when providing discharge teaching?
o A. Report incidents of diarrhea
o B. Avoid foods high in vitamin K
o C. Use a straight razor when shaving
