Answer:

Dobutamine is a catecholamine with β-1 and β-2 adrenergic agonist properties which help improve myocardial contractility.

In patients with cardiogenic shock due to decompensated heart failure, dobutamine decreases left ventricular end-diastolic pressure and raises blood pressure by increasing cardiac output.

laiz [17]

Answer:

0.6mL

Explanation:

In general you can find the actual volume to be administered as follows:

actual volume = (actual amount / dose amount) x dose volume

actual volume = (175mcg / 300mcg) x 1mL = 0.58mL

In practice it would probably be easier to just administer 0.6mL. The difference in dose won't be clinically meaningful.

What purpose does the expanded synaptic knob and the ruffled motor end-plate serve?
dlinn [17]

Answer:

The correct answer will be option C- increase the surface area.

Explanation:

At the neuromuscular junctions, the axons of the motor-neurons become bulbous at terminals. These bulbous enlargements are known as the synaptic knobs. The synaptic knob is the bulbous enlargements of the axon present at the terminals. These knobs increase the volume of the axon terminals embedded with the ligand-gated channels and accumulation of neurotransmitters in vesicles.

The motor end plate is the region of the muscle fiber which is responsible for initiating the action potential in a muscle. The motor end plate becomes ruffled or shows small folds or clefts to increase the increased surface area for the neurotransmitter to act.

Thus, option C is the correct answer.
