A 31-year-old man completes a half-iron triathlon and immediately submits several blood samples for a research protocol on the effects of vigorous exercise on lipids. His triglycerides (TG) are found to elevated at 232 mg/dL. He consumed almost no fat during the race and ate a carbohydrate-rich breakfast. How do you explain his result

Answers

Answer:

The increase in triglycerides can be a result of a diet with excess carbohydrates.

Explanation:

As we saw in the question presented above, the man ate a carbohydrate-rich breakfast. Since he does strenuous exercise, it's likely that all of his meals are high in carbohydrates, so he has a lot of body energy. However, this can generate excess carbohydrate in his body and this excess can stimulate insulin, which in turn stimulates the body's fat cells to form more fat. The increase in body fat is accompanied by an increase in the level of triglycerides, which is one of the components of fat.

Hi. Your question is incomplete and this makes it impossible for it to be answered. However, when researching your question on the internet, I was able to find another question exactly like yours, which asked what was the CID 10 code for this case. So I hope the answer below can help you.

Answer:

C67.9

Explanation:

ICD 10 is a set of international disease codes. These codes aim to create a single language for all healthcare professionals around the world and thus streamline research, treatments and solutions for the problems patients are facing.

Christi Brown is meeting with you regarding the bill she received in the mail. When she called to make the appointment, she voiced her confusion about the bill, stating she thought her insurance covered everything. You check her record and see that she met her deductible and now needs to pay 20% of the billed amount of $850. How can you explain how much she owes, as well as the difference between deductible and coinsurance?

Answers

Answer:

The correct answer is - she owes $170.

Explanation:

Health care beneficiaries bills can be divided into two different criteria, they include Co-pay or Co-insurance and deductibles. Co-insurance is an amount that should be born by the patient and the rest will be paid by the insurance companies. On other hand, Deductible is a criterion in which deductible fixed amount a patient must pay each year before their health insurance benefits begin to cover the costs.

So in this question, the 20% of hospital/health care bills is the co-insured amount that should be paid by Christi Brown and the rest will be born by the insurance company.

so she owes:

20*850/100 = 170.
