[tex]x = \frac{510 - 340}{1 - 0.15} = 200[/tex]

x = 200 gram.

Thus, the correct amount would be - 200 grams.

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.

Mrs. Quinn has just turned 65, is in excellent health and has a relatively high income. She uses no medications and sees no reason to spend money on a Medicare prescription drug plan if she does not need the coverage. She currently does not have creditable coverage. What could you tell her about the implications of such a decision?

Answers

Answer:

If she does not sign up for a medicare prescription drug plan as soon as she is eligible to do so. The answer is (b).

Explanation:

It is correct.

Mrs. Quinn, as a healthy individual with a high income, you may be questioning the need for a Medicare prescription drug plan if you do not currently require the coverage.

However, there are a few important implications to consider before making a decision:

1. Late Enrollment Penalty: Medicare prescription drug plans (Part D) are voluntary, but if you choose to enroll later when you do need coverage, you may have to pay a late enrollment penalty. This penalty is added to your monthly premium and is calculated based on the number of months you were eligible for coverage but did not enroll.

2. Coverage Gap (Donut Hole): Medicare Part D plans often have a coverage gap, also known as the "donut hole." This refers to a temporary limit on what the plan will cover for prescription drugs. If your medication needs change in the future and you require expensive drugs, not having a Part D plan could result in higher out-of-pocket costs during this coverage gap.

3. Future Medication Needs: While you are currently not taking any medications, it's important to consider that health circumstances can change over time. Even though you may be in excellent health now, there is always a possibility that you may need prescription medications in the future. Having a Medicare Part D plan in place can help provide financial protection and access to necessary medications if that situation arises.

4. Financial Planning: Considering your high income, it's essential to evaluate the financial aspect. Medicare prescription drug plans have monthly premiums, deductibles, and copayments. Assessing the potential costs associated with a Part D plan and comparing them to the potential out-of-pocket expenses without one can help you make an informed decision.

5. Creditable Coverage: Lastly, it's important to note that not having creditable coverage, which refers to prescription drug coverage that is at least as good as Medicare's standard coverage, may impact your ability to switch to a Medicare Part D plan later without facing a late enrollment penalty.

Please Answer Fast Before Friday July 23, 2021. Sara, a 14-year-old, has come to the office for her school physical. She is very remote, moody, and unwilling to answer any questions you ask her as part of her physical exam. She seems to have changed a great deal in the past year, and is thinner, more unkempt, and lethargic. You notice also that her mother is constantly badgering her and rolling her eyes in exasperation at her lack of cooperation. What could you do to facilitate the examination and improve communication with Sara? What possible problems could Sara be experiencing? What should you do about the concerns that you have for Sara?

Answers

Answer:

Sara is likely suffering from depression

Explanation:

To facilitate the exam, ask the parent to wait in the waiting area so you and Sara can talk alone. This way Sara will feel more comfortable in discussion with you without her mother hovering.

Sara may be suffering from depression. Her mother's criticism and judgements may be making her feel down or never "good enough".

To address your concerns for Sara:

1. administer a depression screening such as the PHQ-9 depression test questionnaire. If you find Sara is indeed depressed or has thoughts of hurting herself or others, she will need prompt treatment from a qualified health professional.

2. If Sara does NOT have intentions of hurting herself and her behavior is related to parent conflict, friend conflict, etc. then get her permission to have a discussion with her mother about it.

3. provide Sara with local/national hotline for depression and any other mental health resources that are available in your area (therapists, psychiatrists, community centers, etc.)

4. Follow-up with Sara with another visit in a timely manner to access her mental health.

Something is going on with her maybe try taking to her without her mom in the room where it’s one on one
