Afib - CORRECT ANSWER The impulse originates in the Atria • The Atrial rate is > 300 and unable to measure [N/A] • No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A] • The Ventricular rhythm is irregular • QRS within normal limits • If the Ventricular rate is <100 the rhythm is controlled A-fib; if the Ventricular rate is > 100 the rhythm is uncontrolled A-fib • This is a chronic rhythm for some patients Treatment: controlled patients: ant...

NRNP 6566 Midterm Exam Review Questions With Answers Latest (Graded A+) . Describe ways to lessen the hepatic first pass effect Some drugs, such as propranolol or enalapril, undergo significant metabolism during a single passage through the liver. This is called the first-pass effect. When drugs are highly susceptible to the first-pass effect, the oral dose needed to cause a response will be significantly higher than the intravenous dose used to cause the same response. Alternative routes of...
