NUR361 CARDIAC CARE EXAM
QUESTIONS WITH VERIFIED ANSWERS
\.The nurse shows the student a patient's normal sinus rhythm on the cardiac
monitor. The nurse asks the student which waveform represents ventricular
depolarization. What is the correct response?
"The U wave."
"The P wave."
"The QRS complex."
"The T wave." - ANSWERS✔-"The QRS complex."
The P wave represents depolarization of the atria. The QRS complex indicates
depolarization of the ventricles. The T wave represents repolarization of the
ventricles. The U wave, if present, may represent repolarization of the Purkinje
fiber, or it may be associated with hypokalemia.
\.A patient with chest pain arrives in the emergency department. The staff hurries
to perform a 12-lead electrocardiogram (ECG). The patient appears anxious and
asks, "Why are all of these wires being hooked up to me?" Which of the following
would be the best response by the nurse?
, "The electrocardiogram wires will monitor your vital signs so we can see if there
are any changes that require intervention."
"This is an electrocardiogram which will provide information about your heart and
help us to develop the best plan of care for you."
"We will be performing several tests to see which medications are best for you."
"We are implementing this test to take the very best care of you. You shouldn't
worry." - ANSWERS✔-"This is an electrocardiogram which will provide information
about your heart and help us to develop the best plan of care for you."
The best response provides accurate information that addresses the patient's
question. Telling the patient not to worry is nontherapeutic. Telling the patient
there will be several tests may increase the patient's anxiety and does not answer
the patient's question. The ECG will provide only the heart rate, not all vital signs;
the purpose is not for monitoring vital signs, but the electrical conduction of the
heart.
\.The ECG machine is reading "ERROR—Check lead placement." Which of the
following requires correction?
V2 at fifth intercostal space midclavicular line.
V5 at left anterior axillary line at level of V4 horizontally.
V6 at left midaxillary line at level of V4 horizontally.
V1 at fourth intercostal space at right sternal angle. - ANSWERS✔-V2 at fifth
intercostal space midclavicular line.
V4, not V2, is located at the fifth intercostal space at midclavicular line. Correct
lead placement on the chest for a 12 lead electrocardiogram is V1, fourth
