an action on vasoconstrictive hormones in the blood stream? - ANSWER
ACE inhibitor

untreated/undertreated hypertension? Select all that apply. - ANSWER heart
failure

,6. A 66-year-old client presents to the emergency department reporting severe
headache and mild nausea for the past 6 hours. Upon assessment, the client's
BP is 210/120 mm Hg. The client has a history of hypertension and takes 1.0
mg clonidine twice daily. Which question is most important for the nurse to
ask the client next? - ANSWER "Have you taken your prescribed clonidine
today?"
7. The nurse and student nurse are observing a cardioversion procedure. The
nurse is correct to tell the student that electrical current will be initiated at
which time? - ANSWER During ventricular depolarization
8. A nurse is caring for a client with atrial fibrillation. What procedure would
the nurse educate the patient about for termination of the dysrhythmia? -
ANSWER Elective cardioversion
***Pacemakers are implanted for Sinus Bradycardia.
9. When the nurse observes an electrocardiogram (ECG) tracing on a cardiac
monitor with a pattern in lead II and observes a bizarre, abnormal shape to
the QRS complex, the nurse has likely observed which of the following
ventricular dysrhythmias? - ANSWER Premature ventricular contraction
(PVC)
10.The nurse identifies which of the following as a potential cause of premature
ventricular complexes (PVCs)? - ANSWER hypokalemia
11.***PVCs can be caused by cardiac ischemia or infarction, increased
workload on the heart (e.g., exercise, fever, hypervolemia, heart failure,
tachycardia), digitalis toxicity, acidosis, or electrolyte imbalances, especially
hypokalemia.
,12.The nurse is caring for a client with atrial fibrillation. What procedure would
be recommended if drug therapies did not control the dysrhythmia? -
ANSWER Elective cardioversion
13.A client with dilated cardiomyopathy is having frequent episodes of
ventricular fibrillation. What medical treatment does the nurse anticipate the
client will have to terminate the episode of ventricular fibrillation? -
ANSWER internal cardioverter defibrillator insertion
14.The nurse is placing electrodes for a 12-lead electrocardiogram (ECG). The
nurse would be correct in placing an electrode on which area for V1? -
ANSWER Right side of sternum, fourth intercostal space
15.The nurse knows that electrocardiogram (ECG) characteristics of atrial
fibrillation include what? - ANSWER Atrial rate of 300 to 400
16.The nurse is caring for a client newly diagnosed with hypertension. Which
statement by the client indicates the need for further teaching? - ANSWER
"If I take my blood pressure and it is normal, I don't have to take my blood
pressure pills."
17.Which finding indicates that hypertension is progressing to target organ
damage? - ANSWER Retinal blood vessel damage
18.The nurse is teaching a client who is experiencing dizziness to rise slowly
from a sitting or lying position. What is the rationale for the teaching? -
ANSWER Gradual changes in position provide time for the heart to increase
rate of contraction to resupply oxygen to the brain.
, 19.When measuring blood pressure in each arm of a healthy adult, the nurse
recognizes that the pressures: - ANSWER differ no more than 5 mm Hg
between arms.
20.A client is taking 50 mg of oral spironolactone twice a day to assist with
blood pressure control. While the nurse is performing the morning
assessment, the client reports nausea, general muscle cramps, and weakness.
The ECG strip shows a peaked, narrow T-wave, which is a change. What
electrolyte imbalance does the nurse suspect? - ANSWER Hyperkalemia
21.The nurse is teaching a beginning EKG class to staff nurses. As the nurse
begins to discuss the parts of the EKG complex, one of the students asks
what the normal order of conduction through the heart is. What order does
the nurse describe? - ANSWER Sinoatrial (SA) node, atrioventricular (AV)
node, bundle of His, right and left bundle branches, and the Purkinje fibers
22.A 28-year-old client presents to the emergency department, stating severe
restlessness and anxiety. Upon assessment, the client's heart rate is 118 bpm
and regular, the client's pupils are dilated, and the client appears excitable.
Which action should the nurse take next? - ANSWER Question the client
about alcohol and illicit drug use.
23.A patient who had a myocardial infarction is experiencing severe chest pain
and alerts the nurse. The nurse begins the assessment but suddenly the
patient becomes unresponsive, no pulse, with the monitor showing a rapid,
disorganized ventricular rhythm. What does the nurse interpret this rhythm
to be? - ANSWER ventricular fibrillation
24.A healthy adult client is seeing a health care provider for an annual physical
examination. While the nurse is taking the client's vital signs, the client
states, "Occasionally, my heart skips a beat." The nurse believes that the
