Action potentials at a chemical synapse
Ivan

Answer:

Option-A

Explanation:

The impulse generated in the neuron is transmitted in the form of an electrical signal or action potential which gets converted into a chemical synapse to transmit the signal from one synapse to another synapse.

The junction at which the electrical signal is converted into the chemical signal is called a synapse. The neurons which produce the chemicals called neurotransmitter from the axon terminal is called the presynaptic neuron and the neuron which receives the signal through receptors of the dendrites is known as the postsynaptic neuron.  

Thus, Option-A is the correct answer.

How is heart failure with reduced ejection fraction treated?
klasskru [66]

Answer:

Heart failure with reduced ejection fraction (HFrEF) happens when the left side of your heart doesn't pump blood out to the body as well as normal. It's sometimes called systolic heart failure.

Explanation:

Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and beta-blockers are the cornerstone of the heart failure therapy; indicated in virtually every patient with heart failure and reduced ejection fraction. As soon as the left ventricular ejection fraction decreases below 35 % and / or symptoms are still present (NYHA II-IV), a mineralocorticoid receptor antagonist should be added. A rather recent addition to current heart failure therapy with convincing data is the substance combination sacubitril / valsartan. It is indicated for patients with persistent symptomatic heart failure despite optimal medical therapy with ACE inhibitors or ARBs, beta-blockers, and MRAs. Crucial for all mentioned substances is to aim for the maximal tolerated dose.

for a patient receiving an intravenous (iv) infusion of gentamicin, the nurse would monitor which laboratory values?
Fudgin [204]

For a patient receiving an intravenous (IV) infusion of gentamicin, the nurse would monitor the laboratory values such as blood urea nitrogen (BUN) and creatinine.

<h3>What do you mean by Intravenous infusion?</h3>

An intravenous infusion may be characterized as a type of medical technique that significantly administers fluids, medications, and nutrients directly into a person's vein.

According to the context of this question, the monitoring of specific laboratory values is typically dependent on the intravenous (IV) infusion of any particular type of drug or medication. In this case, the laboratory values of blood urea nitrogen (BUN) and creatinine must be monitored by the nurse.
