Qualified Medication Aides (QMA) Practice Exam

Before administering a cardiotonic, checking the pulse rate is crucial because these medications, such as digoxin, have a direct effect on heart function. Cardiotonics typically increase the strength of the heart's contractions and can also influence the heart rate. By assessing the pulse rate, healthcare providers can identify whether the heart rate is within a safe range for administration. A pulse that is too low could indicate that the heart is not effectively pumping blood, potentially leading to serious complications if a cardiotonic is administered.

In addition to pulse rate, other vital signs, such as blood pressure and respiratory rate, are important in a broader context of patient assessment; however, for the specific purpose of administering cardiotonics, the pulse rate is prioritized. Checking temperature may provide insight into a patient's overall health status but does not directly influence the administration of cardiotonics in the same way.
