Atropine 0.5 mg IV

Answer

Metoprolol 5 mg IV

Answer

Adenosine 6 mg IV

Question 3

On cardiac monitoring, the perianesthesia nurse observes a rate of 160 bpm, regular rhythm, narrow QRS complexes, and no visible P waves. This pattern is MOST consistent with:

Accepted Answer

Supraventricular tachycardia (SVT)

Answer

Ventricular tachycardia

Answer

Atrial flutter with 2:1 block

Answer

Sinus tachycardia

Question 4

ST segment elevation on the cardiac monitor

Answer

Heart rate of 90 bpm

Answer

Blood pressure of 138/88 mmHg

Answer

Question 5

The perianesthesia nurse calculates cardiac output using which formula?

Accepted Answer

CO = HR × SV

Answer

CO = HR × SVR

Answer

CO = MAP / CVP

Answer

CO = SV / HR
