The nurse needs to quickly estimate the heart rate for a patient with a regular heart rhythm. Which method will be best to use?
 
  a. Count the number of large squares in the R-R interval and divide by 300.
  b. Print a 1-minute electrocardiogram (ECG) strip and count the number of QRS complexes.
  c. Calculate the number of small squares between one QRS complex and the next and divide into 1500.
  d. Use the 3-second markers to count the number of QRS complexes in 6 seconds and multiply by 10.

Question 2

To determine whether there is a delay in impulse conduction through the atria, the nurse will measure the duration of the patient's

Answer to Question 1

ANS: D
This is the quickest way to determine the ventricular rate for a patient with a regular rhythm. All the other methods are accurate, but take longer.

Answer to Question 2

ANS: A
The P wave represents the depolarization of the atria. The P-R interval represents depolarization of the atria, atrioventricular (AV) node, bundle of His, bundle branches, and the Purkinje fibers. The QRS represents ventricular depolarization. The Q wave is the first negative deflection following the P wave and should be narrow and short.
