How long your muscles can sustain while activity is occurring
Answer: option d= 130 - 150.
Explanation:
From the question, we are given that the man's age= 50, the man weighs= 193 lb (87.5 kg) and the 50 years old man's resting heart rate= 70 beats · min-1. Then, I am asked to calculate the man's target heart rate (THR) zone for 60% to 80%.
Using the Karvonen (HRR) method to calculate the fifty(50) years old man's target heart rate (THR) zone for 60% to 80%, we will need the man's age for this Calculation and the man's resting heart rate (HR).
Important information to note that is not given from the question is that the 50 years old man's estimated maximum heart rate is (220 - 50) = 170.
Step one: Using the formula; maximum heart rate - man's age × zone Percent. --------------------------(1).
Step two: equation (1) + resting heart rate (HR). -------------------------(2).
For the 60 percent = 0.6.
==>( 170 - 70) × .6 = 60.
Then, 60 + 70 = 130.
For the 80 percent= 0.8;
==> (170 - 70) × .8 = 80.
Then, 80 + 70 = 150.
I think that was right of the Nurse to do so because the person in the accident was exposed to someone whose blood was HIV positive, and so now they might have it too.
I would have consulted with the patient about if it was okay to let the other person know that they could now be infected with HIV and if the HIV positive patient said it was fine I would go back and tell the other patient.
hope that helps :)
C. Abstinence. Usually refers to not having sexual intercourse but can also be used to mean not partaking in any risky behaviors.
I would say that <u>a deadly water-borne microorganism in a city's water source</u> would most quickly devastate a human population, merely because a huge number of people uses this water for some kind of a purpose.
