If you consume one 12-ounce can of regular(sugar)soda per day, the excess calories will amount to about_____pounds per year.

Answers

Answer:

The correct answer will be- 35-36 pounds per year.

Explanation:

Soda contains a very high amount of sugar which could be one of the reasons for the excess weight of the population.

If we take 12 ounces of sugar per day which could account for about for 10-12 teaspoons of sugar.

1 teaspoon contains- 4 g of sugar  

12 teaspoons will have- 4 x 12= 48 g of sugar

So per day, we consume- 40-48 g (45 g average) of sugar through soda.

Residents of poor countries tend to have higher rates of infant mortality because:_______

Answer:

Explanation:

Countries that are poor economically have higher infant mortality rates than the countries which are developed and economically rich. Countries like Somalia, Afghanistan, Central African Republic are poor countries and their GDP is very less than developing and developed countries so they invest less in the health care sector compared to developing and developed countries.

Due to this reason, the health care system is poor in these countries and the infant mortality rate is very high. For example in 2018 the infant mortality rate of Afghanistan was 110.6 and Afghanistan was at first position in infant mortality rate.

2. "If a dose is missed, I will take it as soon as possible but not too close to the next dose."
3. "I should notify my healthcare provider of symptoms of hypotension such as dizziness or fainting."
4. "I should avoid the use of salt substitutes containing potassium."

Salt substitute potassium are salt substitutes which contains "potassium chloride" alone or mixed with regular salt which is "sodium chloride", these are available as a way to cut back sodium intake which contributes to high blood pressure. However in this patient, taking salt substitute potassium could pose a health risk because lisinopril raises blood potassium levels, therefore concurrent use of lisinopril and salt substitute potassium would further increase the blood levels of potassium (hyperkalemia) which could cause side effects like irregular heart rhythm and in severe cases lead to kidney failure, muscle paralysis, cardiac arrest.
