Explanation:
In a fish, the heart comprises two chambers, a ventricle, and an atrium. The deoxygenated blood comes through the body, moves into the atrium and then into the ventricle, from where it is pushed towards the body through the gills.
The pumping of the blood via the heart takes place via the capillary beds of the gills and via the tissues’ capillary beds. When the blood come in the capillary beds of the gills it gets slow down. It moves gradually via its path to the tissues and requires skeletal muscular activity to help the blood to mediate towards the heart again. Thus, a fish is dependent upon the physical effort for blood to get circulated again to the heart.
The heart of an amphibian-like the frog exhibits three chambers, two atria and one ventricle. In the process of circulation, that is, in the ventricle, the oxygenated and the deoxygenated blood gets mixed prior to being impelled out of the heart. However, amphibians possess lower metabolisms and thus, they need less oxygen. The requirement of a lesser amount of oxygen puts less pressure on the heart to provide blood with high oxygen. Thus, a heart comprising three chambers is suitable for the requirements of amphibians who could absorb oxygen via their moist skin.
The client with chronic hypertension with a current blood pressure reading of 182/98 mmHg should be managed first. According to the AHA guidelines for hypertension, this is considered as a hypertensive urgency and should be managed first by having the patient lie down comfortably and reassessing the blood pressure again. If there is no improvement, the patient should be referred to a physician and a rapid blood pressure lowering drug should be given (i.e. Clonidine 75 mcg tablet sublingually up to 3 doses every 15 minutes). The patient with right-sided heart failure with edema can be treated non-urgently or as out-patient with diuretics. The patient asking for a refill can be entertained last.
Answer:
Nodes of Ranvier are gaps in the myelin sheath coating on the neural axon. The myelin allows the electrical impulse to move quickly down the axon. The nodes of Ranvier allow for ions to diffuse in and out of the neuron, propagating the electrical signal down the axon.
