Answer to Question 1

ANS:
50
There are 1500 small blocks in a minute, and the nurse will divide 1500 by 30.

Answer to Question 2

ANS: C
The patient has sinus tachycardia, which may have multiple etiologies such as pain, dehydration, anxiety, and myocardial ischemia. Further assessment is needed before determining the treatment. Vagal stimulation or -blockade may be used after further assessment of the patient. Electrical cardioversion is used for some tachydysrhythmias, but would not be used for sinus tachycardia.
