Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
Torso trauma is an injury involving the chest and abdomen.
Answer:
The correct answer is option D.
Explanation:
The vasoconstriction or the narrowing of the blood vessels regulate the filtration rate of the glomerulus. The afferent arteriole vasoconstriction decreases the flow of blood to the glomerulus thus, decreases the filtration rate
The vasoconstriction of the efferent arteriole increases the glomerular filtration rate due to the increase in the blood level in the glomerular capillaries.
Thus, option D is the correct option.
The correct answer is D. Hypertension.
Explanation
Arterial hypertension is a disease of the circulatory system of the human body in which the pressure of blood flow through the veins and arteries increases above normal levels increasing the risk of cardiovascular accidents, coronary heart disease, heart failure, cerebrovascular accidents, and renal insufficiency.
A third of the world's population suffers from this condition and it is the first cause of visiting the doctor. Also, this disease is related to certain habits including, eating habits, sports activities, and the consumption of substances such as cigarettes and alcohol. So, the correct answer is D. Hypertension
The nurse should administer 0.8 mL ceftriaxone IM.
<h3>How to calculate the value?</h3>
Determine the infant's weight in kg: 2.2 lb / x kg
= weight in lb / 1 kg; 2.2 lb / x kg = 17.6 lb / 1 kg.
Cross multiply and x = 8 kg
Find total of one-time dose:
Amount prescribed x kg weight (mg x kg)
= total daily dose; 50 mg x 8 kg = 400 mg
What is the dose needed?
Dose needed = Desired; Desired = 400 mg
What is the dose available?
Dose available = Have; Have = 500 mg
Set up an equation using knowledge about basic equivalents.
Desired x Quantity / Have
= Amount to be given; 400 mg x 1 mL / 500 mg = x mL; 400 x 1
= 400 ÷ 500 = 0.8 mL
