Suggest why captopril or other ACE inhibitors might fail to lower a patient's blood pressure?

rjkz [21]

Answer:

Angiotensin-converting enzyme (ACE) inhibitors are commonly prescribed to treat high blood pressure, heart problems and other conditions. Find out how they work and their possible side effects.

Angiotensin-converting enzyme (ACE) inhibitors help relax veins and arteries to reduce blood pressure. ACE inhibitors prevent an enzyme in your body from producing angiotensin II, a substance that narrows your blood vessels. This narrowing can cause high blood pressure and force the heart to work harder. Angiotensin II also releases hormones that raise blood pressure.

In addition to high blood pressure, angiotensin-converting enzyme inhibitors prevent, treat or improve symptoms in conditions such as the following:

Coronary artery disease

Heart failure

Diabetes

Certain chronic kidney diseases

Heart attacks

Scleroderma: a disease that involves hardening of the skin and connective tissues

Migraines

The doctor may prescribe other medications in addition to an angiotensin-converting enzyme inhibitor, such as a diuretic or a calcium antagonist. Angiotensin-converting enzyme inhibitors should not be taken together with angiotensin receptor blockers or with direct renin inhibitors.

Angiotensin-converting enzyme inhibitors work better for younger people than for older people. They also work better for white people than for black people. The doctor may recommend a different medication.

Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of w

sp2606 [1]

Answer:

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year 1950 1965 1975 1990 2005

Amount 180 340 420 410 410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.
