ANSWERS
A nurse is preparing to administer medication through a central
line. Which technique ensures patient safety?
A. Administer the medication without flushing if the line was
recently used.
B. Use sterile gloves and a sterile syringe for accessing the line.
C. Push medications as fast as possible to reduce procedure
time.
D. Flush the line with 5 mL of saline between medications.
Correct Answer Use sterile gloves and a sterile syringe for
accessing the line.
A 67-year-old patient presents with fatigue, shortness of breath,
and a rapid, irregular pulse. An EKG reveals a wavy baseline with
no discernible P waves and an irregularly irregular rhythm. What
is the most likely diagnosis?
A. Sinus tachycardia
B. Atrial flutter
C. Atrial fibrillation
,D. Ventricular tachycardia Correct Answer Atrial fibrillation
A 55-year-old male presents to the emergency department with
chest pain radiating to his left arm, nausea, and diaphoresis. An
EKG reveals ST-segment elevation in leads II, III, and aVF. What
is the priority intervention?
A. Administer a beta-blocker.
B. Schedule an echocardiogram.
C. Perform an angioplasty within 90 minutes.
D. Administer 4 mg of morphine immediately. Correct Answer
Perform an angioplasty within 90 minutes.
While reviewing an EKG, a nurse notes the PR interval is 0.25
seconds. What does this finding indicate?
A. Normal conduction between the atria and ventricles
B. Prolonged filling time from atrial contraction to ventricular
contraction
C. Ventricular depolarization is delayed
D. The heart is in atrial fibrillation Correct Answer Prolonged
filling time from atrial contraction to ventricular contraction
A 60-year-old patient is admitted with chest pain and an initial
normal troponin level. The EKG shows ST depression and T wave
inversion. Troponin levels increase to 0.5 ng/mL after six hours.
What is the most likely diagnosis?
,A. STEMI
B. NSTEMI
C. Atrial flutter
D. Stable angina Correct Answer NSTEMI
A 45-year-old marathon runner presents to the clinic for a routine
check-up. During the examination, their heart rate is measured at
52 beats per minute, with no other symptoms. What is the most
likely explanation for this finding?
A. Sinus bradycardia, asymptomatic due to physical fitness
B. Atrial fibrillation with a slow ventricular response
C. Second-degree heart block, Mobitz Type II
D. Sick sinus syndrome requiring immediate intervention Correct
Answer Sinus bradycardia, asymptomatic due to physical
fitness
A patient is admitted for evaluation of fatigue and mild shortness
of breath. The EKG shows a "sawtooth" pattern, with a ventricular
rate of 75 beats per minute. What is the best description of this
rhythm?
A. Sinus tachycardia
B. Atrial fibrillation with rapid ventricular response
C. Atrial flutter with 4:1 conduction
, D. Ventricular tachycardia Correct Answer Atrial flutter with 4:1
conduction
A 70-year-old patient with a history of hypertension presents with
an irregularly irregular pulse. EKG reveals the absence of
discernible P waves. Which of the following is the priority nursing
intervention?
A. Administer atropine IV.
B. Prepare the patient for defibrillation.
C. Monitor for signs of rapid ventricular response (RVR).
D. Initiate CPR immediately. Correct Answer Monitor for signs of
rapid ventricular response (RVR)
A patient presents with crushing chest pain. Their EKG reveals ST
elevation in leads V2-V4, and their troponin level is significantly
elevated. What is the primary difference between a STEMI and an
NSTEMI?
A. STEMI involves partial occlusion of a coronary artery; NSTEMI
involves complete occlusion.
B. STEMI is associated with ischemia; NSTEMI is associated with
tissue death.
C. STEMI involves ST elevation; NSTEMI involves ST depression
or T-wave inversion.
D. STEMI has normal cardiac enzymes; NSTEMI has elevated
cardiac enzymes. Correct Answer STEMI involves ST elevation;
NSTEMI involves ST depression or T-wave inversion.
