Gala2k [10]3 years ago
7 0

Answer:

The correct answer is B:  

HR = 80% of age-predicted maximum is NOT a reason to stop maximal GXT.

Explanation:

<u>Maximal graded exercise test</u> allows physicians to evaluate patients ability to perform cardiovascular exercise (functional capacity), an also detect if there are any zones of ischemia in the muscle heart due to arteriosclerosis.

To do so, the patient would be asked to walk on a treadmill and speed and slope of the treadmill will be increased gradually during the test. EKG, heart rate, and blood pressure will be recorded and compared afterwards.

The heart rate target to make a proper evaluation is 85% of the maximal predicted heart rate.

Answer:

By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)

Explanation:

Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.

The order is to give 45 mEq. The dosage available is 30 mEq in 15 mL. How many mL do you give?
snow_lady [41]

Based on the dosage available, the amount in mL of the drug required is 22.5 mL.

<h3>What is drug dosage?</h3>

Drug dosage refers to the amount of drug that should be taken by a patient in order to produce effective pharmacodynamic results.

The dosage of the drug to be given is 45 mEq.

The dosage available is 30 mEq in 15 mL.

In order to give this required dosage the amount in mL required is calculated as follows:

30 mEq is in 15 mL

45 mEq will be in x mL

x = 45 * 15/30

x = 22.5 mL

In conclusion, drug dosage refers to the amount of drug required to produce good results in the patient.

damaskus [11]

Answer:

Although the text of your question is incomplete, we can affirm that the reasoning behind the carbohydrate loading is that if an individual increases the amount of carbohydrates that he or she ingests, he or she will have more energy and will be able to perform activities that require a lot of effort physical, with less fatigue.

Explanation:

Carbohydrate is an energetic molecule, as it provides fast energy to our body. Carbohydrate can be acquired through food, mainly in pasta, sweet potatoes, rice, cassava and other foods.

the more carbohydrates a person eats, the more fast energy that person will have and that is the basis of the reasoning behind the carbohydrate loading.

The carbohydrate loading is the term that refers to a type of diet practiced by athletes who participate in exercises that require a lot of resistance, such as marathon runners, for example. This diet consists of greatly increasing the intake of carbohydrates, allowing the athlete to have a lot of body energy and be able to finish his activities with less tiredness. However, this diet is very controversial, first because there is no scientific proof that it works and because the amount of carbohydrate it requires is very difficult to achieve.
