Jessica's new diet plan contains 3.3 mg of heme iron and 17.5 mg id non heme iron. what us the amount of biologically available

Hitman42 [59]

1.37mg is a total concentration of iron.

Further Explanation:

Iron is a vitally important element that is required for oxygen transport as a component of hemoglobin. Haemoglobin is composed of two components; heme and globin chain. Heme is further composed of two component; iron and porphyrin ring and globin is a protein chain. Heme part of the hemoglobin helps in binding oxygen component whereas globin chain helps in transport because it is soluble in body fluid. When heme group breaks down it release iron and phosphorus in the body fluid. Iron is obtained from dietary source.

The naturally occurring iron is formed in two forms; heme and non heme iron in food that are handled and absorbed by the human cell differently. Heme iron is a kind of iron present in muscle tissue and blood. The source of heme iron is meat, seafood, poultry and fish. It is generally present in the form of animal protein. Non heme protein is a plant as well as animal based iron. They are present in beans, grain, vegetables, fruits, seed, nuts, egg and milk. Heme iron is absorbed more easily in human body than non heme iron.

Biologically available heme can be calculated by the formula given below.

$\text{Biologically available}=\dfrac{\text{dietary intake}\times\text{absorption}}{100}$

The concentration of heme iron can be calculated by,

$\begin{aligned}{\text{Heme iron}}&=\frac{{3.3 \times 15}}{{100}}\\&=0.49{\text{ mg}}\end{aligned}$

Calculate the non heme concentration by,

$\begin{aligned}{\text{Non - heme iron}}&=\frac{{17.5\times5}}{{100}}\\&=0.875{\text{ mg}}\end{aligned}$

Total concentration of iron,

$\begin{aligned}{\text{Total iron}}&=0.49+0.875\\&=1.37{\text{ mg}}\end{aligned}$

which statement by the adolescent indicates that the client understands instruction regarding resumption of physical activities

Misha Larkins [42]

I can't perform any weightlifting for at least 6 weeks. This statement by the adolescent indicates that the client understands the instructions.

Weight lifting puts strain on the incision and should be avoided for at least 6 weeks. After uncomplicated hernia surgery, activities such as bicycling, physical education, and soccer are contraindicated for approximately 3 weeks. Refraining from these activities during this time will prevent stress on the incision and promote healing. However, clients should not participate in these activities until directed by a surgeon.

A hernia occurs when tissue, such as a piece of intestine, protrudes through a weak abdominal muscle. It can swell and become painful, especially when coughing, bending over, or lifting heavy objects. However, many hernias do not cause pain. Hernias are not always dangerous.

An inguinal hernia can be repaired with surgery that pushes the bulge back into place and increases the weakness of the abdominal wall. Surgery is usually recommended if you have a hernia that causes pain, severe or persistent symptoms, or if you have serious complications.

Complete Question:

An adolescent who had an inguinal hernia repair is being prepared for discharge home. Thenurse provides instructions about resumption of physical activities. Which statement by theadolescent indicates that the client understands the instructions?

(a) I can ride my bike in about a week.

(b) I don't have to go to gym class for 3 months.

(c) I can't perform any weightlifting for at least 6 weeks.

(d) I can never participate in football again.

kipiarov [429]

Answer:

Hey bud,

Did you know vaping causes you to crave a smoke and suffer withdrawal symptoms if you ignore the craving. Nicotine is also a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack. Heart attacks killed 365,914 people in 2017. Next time you take a puff of smoke remember that that could be your last days on earth.
