Nurs 422 Exam 2 With
Complete Solution
Atrial fibrillation - ANSWER While assessing a client with dilated
cardiomyopathy, the nurse notices that the electrocardiogram rhythm has no
p waves, on a fine, wavy line. The ventricular rhythm is irregular with a QRS
duration of 0.08 seconds, and a heart rate of 110 BPM. This rhythm is:
atrial fibrillation
ventricular fibrillation
atrial flutter
sinus tachycardia
pulse rate has increased to 70 BPM - ANSWER The vital signs of a patient are:
BP 100/78, pulse 46 BPM, RR 18 breaths/min. Atropine is administered IV
push. What assessment indicates a therapeutic response to the medication?
systolic blood pressure has increased by 20 mmHg
pupils are dilated
oral secretions have decreased
pulse rate has increased to 70 BPM
ventricular tachycardia - ANSWER A nurse is watching the cardiac monitor
and notices that a patient has no p-waves, the QRS complexes are wide, and
the ventricular rate is regular but over 100. The nurse determines that the
,patient is experiencing:
premature ventricular contractions (PVCs)
ventricular tachycardia
ventricular fibrillation
sinus tachycardia
blood pressure and peripheral perfusion - ANSWER A client is having
frequent premature ventricular contractions. The nurse would place a priority
on assessment of which of the following items?
sensation of palpitations
causative factors such as caffeine
blood pressure and peripheral perfusion
precipitating factors such as infection
hypotension and dizziness - ANSWER A client has developed atrial
fibrillation, with a ventricular rate of 150 BPM. A nurse assesses the client for:
nausea and vomiting
hypotension and dizziness
hypertension and headache
flat neck veins
vagus nerve to slow the heart rate - ANSWER A client with rapid rate atrial
fibrillation asks a nurse why the physician is going to preform carotid
,massage. The nurse responds that this procedure may stimulate the:
vagus nerve to increase the heart rate; overriding the rhythm
diaphragmatic nerve to slow the heart rate
vagus nerve to slow the heart rate
diaphragmatic nerve to override the rhythm
ventricular fibrillation - ANSWER A nurse notes that a client with sinus
rhythm has a PVC that falls on the T wave preceding a beat. The client's
rhythm suddenly changes to one with no p-waves or definable QRS
complexes. Instead there are coarse wavy lines of varying amplitude. This is:
ventricular fibrillation
ventricular tachycardia
atrial fibrillation
asystole
notify the physician promptly - ANSWER When caring for a client who has
sustained an MI, the nurse notes eight PVCs in 1 minute on the cardiac
monitor. The client is receiving an IV infusion of LR and oxygen at 2L/min.
The nurses first action is to:
, increase the IV infusion rate
notify the physician promptly
increase the oxygen concentration
administer the prescribed analgesic
syncope and slow ventricular rate - ANSWER A client with a complete heart
block may exhibit:
nausea and vertigo
flushing and slurred speech
cephalalgia and blurred vision
syncope and slow ventricular rate
the RR intervals are relatively consistent
one P wave precedes each QRS complex - ANSWER What criteria should the
nurse use to determine normal sinus rhythm for a client on a cardiac
monitor? Select all that apply.
the RR intervals are relatively consistent
one P wave precedes each QRS complex
