How can the medical assistant take steps to ensure the ecg reading is accurate?

The ECG is the electrocardiogram used to determine the electrical activity of the heart.

The ECG is the is performed by placing different electrodes at different position on the chest. To make sure the ECG readings are accurate all the electrodes should be placed correctly on the chest.

The misplacement of the ECG electrodes are the main reason of the obtaining an incorrect ECG. Also, the interpretation should be done accurately according to the time versus electric activity graph.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
