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?
A. Decrease in arterial oxygen saturation (SaO2) when
measured with a pulse oximeter
B. Increase in systemic blood pressure
C. Presence of premature ventricular contractions (PVCs)
on a cardiac monitor
D. Increase in intracranial pressure (ICP)
E. A drop in serum potassium levels as indicated in the
latest lab results
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
,NCLEX Practice Questions Test Bank 2025/2026

should the nurse prioritize when providing discharge
teaching?
A. Report incidents of diarrhea
B. Avoid foods high in vitamin K
C. Use a straight razor when shaving
D. Take aspirin for pain relief
E. Monitor for signs of bleeding, such as bruising or black
tarry stools
F. Check blood pressure regularly at home
G. Inform all healthcare providers about the anticoagulant
therapy
Correct Answer: B. Avoid foods high in vitamin K
Clients taking warfarin should be educated about
maintaining a consistent intake of vitamin K, as it is
necessary for the clotting cascade, and warfarin works by
inhibiting the effects of vitamin K, thereby reducing the
blood’s ability to clot. Sudden increases in vitamin K intake
can decrease the effectiveness of warfarin and increase

the risk of clot formation. Clients should also be advised to
report any incidents of diarrhea (A) since it can affect the
absorption of the medication and potentially lead to
unstable anticoagulation levels. Using a straight razor (C)
is not advised due to the increased risk of bleeding; a
safety razor or electric razor would be safer alternatives.
Taking aspirin for pain relief (D) is not recommended
without a physician’s approval because aspirin can
increase the risk of bleeding when taken with an
anticoagulant. Monitoring for signs of bleeding (E),
checking blood pressure regularly (F), and informing all
healthcare providers about anticoagulant therapy (G) are
also important instructions for a patient on warfarin
therapy, but avoiding foods high in vitamin K is directly
related to the effectiveness of the anticoagulant
medication and is thus the priority teaching point.

I.V. catheter for a 33-year-old patient who is scheduled for
elective surgery and has a notably hairy forearm where
