<em>Hi,</em>

<em>The valves in the heart open and close to move blood in between heart chambers. </em>

d) one direction

<em>Blood can flow from the atria down into the ventricles because there are openings in the walls that separate them. These openings are called valves because they open in one direction like trapdoors to let the blood pass through. Then they close, so the blood cannot flow backwards into the atria.</em>

Describe the deductible, coinsurance, and copayment requirements for an HMO plan.
Pavlova-9 [17]

Answer:

A deductible is the amount you pay for health care services before your health insurance begins to pay. The deductible in the HMO Plan will pay the full charges once you have reached the total deductible. You will start paying less, with a copay or coinsurance, depending on the selected plan. When the limit is reached, you share the cost with your plan by paying coinsurance.

Coinsurance is a percentage of a medical charge that you pay, with the rest paid by your health insurance plan, that typically applies after your deductible has been met. Let's say your health insurance plan's allowed amount for an office visit is $50 and your coinsurance is 20%. All you have to pay is the 20% and your coinsurance will pay the rest.

A health insurance copayment is a fixed amount a healthcare beneficiary pays for covered medical services. The rest of the balance is paid for by the person's insurance company. Copays for standard doctor visits are typically lower than those for specialists.

Which possible outcome would be a major disadvantage of any pain relief method that also affects awareness of the mother
Reptile [31]

The possible outcome would be a major disadvantage of any pain relief method that also affects awareness of the mother is that the mother may have difficulty working effectively with contractions.

Epidural :

The epidural is one of the most efficient ways to relieve pain during childbirth and delivery, and it has little side effects  on both the mother and the newborn. During lengthy surgical operations, such as a C-section delivery, or while recovering from specific treatments, an epidural can offer continuous pain relief.

Some of the disadvantage of using pain relief :

  • The blood pressure may drop suddenly after receiving an epidural.
  • Shivering, fever, or itching are a few adverse symptoms that some women report.
  • One can experience nausea or vertigo after having the epidural removed, along with back pain and soreness where the needle was inserted.
  • With an epidural, some women report having more trouble giving birth. The likelihood of requiring interventions like forceps, drugs, or a C-section may rise significantly.
