Explanation:They are inactivated H1N1 virus vaccines used for immunization of individuals 6 months of age and older against influenza disease caused by H1N1 2009 virus.
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:
Sexual and drug substance use risks should be determined during a routine health history with every new patient and updated regularly during periodic health care.
Risk assessment helps to identify individuals at risk; support recommendations for HIV, STD, and hepatitis screening; and establish risk reduction education topics and strategies.
Risk assessment can help people who are already infected access treatment
and learn how to avoid transmitting HIV to others.
Explanation:
Studies show that a 1% increase in dietary saturated fatty acids will raise the risk of heart disease by 2%.
Saturated fatty acid :
A saturated fatty acid is a type of fatty acid that lacks unsaturated linkages between carbon atoms. This type of fatty acid is saturated because it no longer has any double bonds, which prevents it from absorbing any more hydrogen. Animal fats frequently contain saturated fatty acids.
In the worldwide, cardiovascular disease (CVD) is the leading cause of death and disability. Additionally, a poor diet is a major CVD risk factor. Therefore, changes in diet may help to considerably lower the occurrence of CVD. It is well known that saturated fatty acids (SFA) raise LDL cholesterol, a major risk factor for cardiovascular disease.
