In this case, the SA node depolarizes 80 times in a minute. SA node depolarization depends on electrical stimuli.
<h3>Sinoatrial node depolarization</h3>
The sinoatrial (SA) node can be considered as a fundamental pacemaker located in the heart.
This node (SA node) depends on electrical stimuli that spread in the atrial muscle to produce muscle contraction.
At a normal heart rate, the SA node depolarizes at a regular rate of 60-100 beats in a minute (min).

2nd reason is that you could use the heroin incorrectly and possibly give yourself a deadly amount and easily overdose on it
Answer:
B. With a submersion injury, hypoxia is the primary problem. Therefore, assessment of airway, breathing, and circulation are the priority assessments for which the nurse would institute resuscitative measures. Other assessments such as level of consciousness, vital signs, and papillary response would be done once the child's airway, breathing, and circulation are assessed and emergency interventions are instituted.
The correct answer is: Airway, breathing, and circulation
Explanation:
I think? not sure about it though
