ATI RN COMPREHENSIVE PREDICTOR 2019 FORM A
1. The nurse suspects the patient has increased afterload. Which piece of
equipment should the nurse obtain to determine the presence of this
condition?
a. Pulse oximeter



b. Oxygen cannula
c. Blood pressure cuf



d. Yankauer suction tip catheter



ANS: C

A blood pressure cuf is needed. The diastolic aortic pressure is a good clinical
measure of afterload. Afterload is the resistance to left ventricular ejection. In
hypertension the afterload increases, making cardiac workload also increase. A
pulse oximeter is used to monitor the level of arterial oxygen saturation; it will
not help determine increased afterload. While an oxygen cannula may be
needed to help decrease the efects of increased afterload, it will not help
determine the presence of afterload. A Yankauer suction tip catheter is used to
suction the oral cavity.

2. A patient has heart failure and cardiac output is decreased. Which
formula can the nurse use to calculate cardiac output?
a. Myocardial contractility × Myocardial blood flow



b. Ventricular filling time/Diastolic filling time
c. Stroke volume × Heart rate



d. Preload/Afterload



ANS: C

236

,Cardiac output can be calculated by multiplying the stroke volume and the
heart rate. The other options are not measures of cardiac output.

3. A patient’s heart rate increased from 94 to 164 beats/min. What will the
nurse expect?
a. Increase in diastolic filling time



b. Decrease in hemoglobin level
c. Decrease in cardiac output



d. Increase in stroke volume



ANS: C

With a sustained heart rate greater than 160 beats/min, diastolic filling time
decreases, decreasing stroke volume and cardiac output. The hemoglobin level
would not be afected.

4. The nurse is careful to monitor a patient’s cardiac output. Which goal is
the nurse trying to achieve?
a. To determine peripheral extremity circulation



b. To determine oxygenation requirements
c. To determine cardiac dysrhythmias



d. To determine ventilation status



ANS: A

Cardiac output indicates how much blood is being circulated systemically
throughout the body to the periphery. The amount of blood ejected from the
left ventricle each minute is the cardiac output. Oxygen status would be
determined by pulse oximetry and the presence of cyanosis. Cardiac
dysrhythmias are an electrical

237

, impulse monitored through ECG results. Ventilation status is measured by
respiratory rate, pulse oximetry, and capnography. Capnography provides
instant information about the patient’s ventilation. Ventilation status does
not depend solely on cardiac output.
