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
