A client has been diagnosed with right-sided heart failure based on symptomology. The cardiologist will confirm this suspicion through diagnostics. Which diagnostics are used to reveal right ventricular enlargement?A. electrocardiogramB. chest radiographC. echocardiography

A. electrocardiogram and C. echocardiography.

Explanation:

The two diagnostics used to confirm if a person has ventricular enlargement are electrocardiogram and echocardiography. Electrocardiograms mostly detect the electrical activity of the left ventricle, and if there is a problem on the right ventricle, it might be hard to confirm it with this procedure, so the best option is to complement it with echocardiography since it gives an image of the right ventricle walls.

The correct answer to the question is option A

ELECTROCARDIOGRAM

Explanation: Right sided heart failure is otherwise known as pulmonary heart disease or cor pulmonale.

In a healthy heart,deoxygenated blood enters the right atrium through the superior and inferior vena cava,the right atrium contracts opening the tricuspid valve and making way for the blood to empty into the right ventricle.the right ventricle further contracts and the pulmonary valve opens,the deoxygenated blood from the right ventricle goes into the pulmonary trunk and into the right and left pulmonary artery,the right and left pulmonary artery empties the deoxygenated blood into the right and left lungs for gaseous exchange.(oxygenation)

When the right side of the heart is diseased,there will be a failure in carrying out the above stated functions.

Right sided heart failure is simply defined as the inability of the right side of the heart to take-up or pump deoxygenated blood into the lungs for oxygenation.

The sign and symptoms if right sided heart failure are mainly lethergy, dyspnea, fatigue and oedema.

Electrocardiogram is one of the diagnostic procedure for right sided heart failure,it will reveal an impairment in the heart rate and rythym and also an impairment in pulmonary artery pressure.

equal distribution i think.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
