Hopefully this is right:
Comes in through superior and inferior vena cava, then enters right atrium, then tricuspid valve and into the right ventricle. Then the deoxygenated blood gets pumped through the pulmonary artery to the lungs. Oxygenated blood comes back through pulmonary vein and into left atrium. Then goes through mitral valve and into left ventricle which then pumps the blood through aorta.
Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
Medicare Advantage (MA) plans are privately planned healthcare offered by contracting with Medicare to provide Part A and Part B health benefits to patients. MA part A plan covers hospital insurance and MA Part B plan covers medical insurance. Most of the MA plans also covers prescription drugs and most of the Medicare services are covered. Common MA plans include Health Maintenance organization (HMO) plans, Preferred provider Organization (PPO) plans, private fee-for-service (PFFS) plans, and Special Needs Plan (SNPs).
Explanation:
Mrs. Davenport is already enrolled in a MA plan before she has developed ESRD. Therefore, her plan will continue after getting the ESRD diagnosis and the MA plan chosen by Mrs. Davenporrt cannot charge more than the original Medicare cost for dialysis and coverage of immunosuppressant drugs. Moreover both part A and part B medicare plans have annual budget for out-of-pocket costs thus the increasing healthcare cost of Mrs. Davenport after the ESRD diagnosis can be covered through renewal of annual budgeting. Moreover, if the previous Medicare advantage plan is not functional in the service area, then Mrs. Davenport could enroll in Special Enrollment period and may get another Medicare advantage plan in their area.
At the shoulder, the head of the humerus articulates with the glenoid fossa of the scapula. More distally, at the elbow, the capitulum of the humerus articulates with the head of the radius, and the trochlea of the humerus articulates with the trochlear notch of the ulna.
