Which class iv calcium channel blocker is exclusively administered to treat acute supraventricular tachycardia?

1 answer:

3 0

The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem. Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.

Answer:

d) 2v

Explanation:

Since, root mean square speed of a molecule,

$V_{rms}=\sqrt{\frac{3kT}{m}}$

Where,

k = Boltzmann constant,

T = temperature of gas,

m = mass of molecule,

Also, the temperature of a gas,

$T=\frac{pV}{nR}$

Where,

p = pressure of the gas,

V = volume,

n = number of moles of gas,

R = universal gas constant,

$\implies V_{rms}=\sqrt{\frac{3kpV}{mnR}}$

If V = 2V and p = 2P

Then,

$V_{rms}=\sqrt{\frac{12kpV}{mnR}$

$=2\sqrt{\frac{3kpV}{mnR}$

Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v

i.e. option d is correct.

How does mutation effect genes

Harman [31]

Answer: When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth
