what are the primary determinants limiting max heart rate in a person?

Answers

Answer 1
Blood volume. If you are tired and no blood is able to get to your body and you heart keeps going faster your heart is probably going to fail.
Answer 2

The primary determinant limiting maximum heart rate in a person is age, calculated as 220 minus one's age. There can be variances, but this guides exercise intensity to target heart rate zones. Monitoring heart rate during exercise is crucial to avoid overexertion.

One of the primary determinants limiting maximum heart rate (MHR) in a person is age. The estimated MHR is typically calculated as 220 beats per minute minus the person's age. This relationship suggests that as a person ages, the maximum heart rate he or she can achieve decreases. Despite this general formula, there can be variances between this calculated value and an individual's actual MHR as determined through laboratory testing.

For cardiovascular exercises, it's important to exercise within your target heart rate (THR), which is usually set between 50 to 70% of your MHR. As the heart rate increases during physical activity, cardiac output (CO) increases up to a point; beyond certain heart rates, CO may actually decrease due to the decreased stroke volume (SV) resulting from shorter diastolic filling times. Therefore, monitoring your heart rate during exercise is essential to stay within a safe range that allows an optimal workout without overexerting the heart.

which of these tools can be used to detect breast cancer ? select two correct answers

A . cervical exams
B . Clinical exams
C . Mammograms
D . Pap smears

Answers

Correct Answers:
B . Clinical exams C . Mammograms 

Mammogram is the process of examining the Human Breast by the use of low energy X-rays for the purpose of diagnosis and screening. In clinical exams the doctor investigates the body for the sign of diseases. Both these tools can help in detection of Breast Cancer. Cervical Exams and Pap Smears are used for the tests and investigation in cervical region and can help in detection of cervical cancer.

The correct options are C. Mammograms, it can often find breast cancer at an early stage, when treatment is most likely to be successful. and B. Clinical exams, they are not as sensitive as mammograms in detecting early-stage breast cancer,

Mammograms are specialized X-ray images of the breast that are used to screen for breast cancer. They are the most effective tool for the early detection of breast cancer and can detect tumors that are too small to be felt by hand. Mammograms can often find breast cancer at an early stage, when treatment is most likely to be successful.

Clinical exams, which include breast self-exams and exams by a healthcare provider, are also important in the detection of breast cancer. During these exams, the breasts are checked for lumps, changes in size or shape, and other abnormalities. They can still play a crucial role in identifying potential issues that need further investigation.

The other incorrect option are:

Cervical exams (A) and Pap smears (D) are used to detect cervical cancer, not breast cancer. A cervical exam, also known as a Pap test, involves collecting cells from the cervix to look for changes that could indicate cervical cancer or precancerous conditions. While both cervical exams and Pap smears are important for women's health, they are specific to the cervix and do not aid in the detection of breast cancer.

I am taking a new medication called amitriptyline and it is an Antidepressant. If it is an antidepressant then how is a side effect depression and sadness???

Answers

Because not all bodies respond to medication the same way. Some antidepressants might not work as well or your body might not respond to it as it should. Therefore this reaction could trigger an even greater feeling of sadness or depression or you could feel like they antidepressants aren't doing anything. If you have any comments or concerns I suggest you talk to your pharmacist or doctor. Also remember not all bodies might trigger the same side affects.

Answer:

The side effect you mentioned, depression and sadness, might seem counterintuitive since amitriptyline is an antidepressant. However, it's important to understand that medications affect individuals differently, and side effects can vary from person to person.  In the case of amitriptyline, it is classified as a tricyclic antidepressant. While it is primarily used to treat depression, it can, in some cases, initially worsen symptoms of depression or cause other mood changes, such as sadness. This can occur during the early stages of treatment as your body adjusts to the medication.  These side effects are usually temporary and may improve as your body becomes accustomed to the medication. It is important to communicate any concerns or changes in mood to your healthcare provider, as they can help monitor your progress and adjust your treatment plan accordingly.  Remember, everyone's experience with medication can be different, so it's important to consult with your healthcare provider if you have any concerns or experience any unexpected side effects. They will be able to provide you with the best guidance based on your individual circumstances.

describe two ways in which a lack of access to health care can affect treating a person for cardiovascular disease

Answers

The patient wouldn't be able to access health care to treat such a dangerous problem. As well if this patient is a middle or low class financial situation. Meaning his/her condition could worsen.
Another reason that it could affect them is that by not being able to access or has a limited access to healthcare is he/her could not get the right treatment or diagnosis. This could affect how her/his condition worsens.

Answer:

The patient may not have sufficient economic conditions to pay for quality medical care, and the patient may not have access to a health plan that covers cardiovascular disease treatments.

Explanation:

Cardiovascular disease used to designate a group of diseases that affect both the heart and blood vessels. Because it is a serious problem that can lead the patient to sudden death, medical services and health plans that address this type of problem can be very costly, making it difficult for low- and middle-income families to afford to pay for these services. As a result, many people with cardiovascular disease but without sufficient financial resources end up not having access to adequate health care and end up suffering from the disease.
