Ian is another of Josie’s clients. He is 60 years old. What is the MHR for Ian when he is training
Answers
Answer:
166 bpm
Step-by-step explanation:
Ian's age = 60
MHR stands for maximum heart rate. There are two methods of calculating the MHR :
1) MHR = 220-age
2) MHR = 217-(0.85×Age)
Both the methods are easy to solve but the most accurate is the second one, hence we use the second method to calculate MHR of Ian.
MHR = 217-(0.85×Age)
= 217-(0.85×60)
166
Since the MHR is calculated in beats per minute (bpm)
Therefore, MHR of Ian = 166bpm
MHR=190-(60-30)/2
MHR=190-(30/2)
MHR=190-15
MHR=175 bpm

Answer:
The nurse should use 200cc of the 10% saline solution in order to produce a 20% saline solution.
Step-by-step explanation:
to the given mix we add a quantity of a lower mix to generate another.
50cc at 60% + Xcc at 10% = (50 + X)cc at 20%
50 x 60% + X x 10% = (50 + X) x 20%
30 + 0.1X = 10 + 0.2X
30 - 10 = 0.2X - 0.1X
20 = 0.1X
20/0.1 = X
X = 200
Final answer:
To produce a 20% saline solution, the nurse should use 200 cc of the 10% saline solution.
Explanation:
To find out how much of the 10% saline solution the nurse should use, we can set up an equation using the idea that the amount of saline in the mixture is equal to the sum of the amounts of saline in each solution.
Let's say the nurse uses x cc of the 10% saline solution. The amount of saline in the 60% saline solution will be 0.6 * 50 cc = 30 cc. The amount of saline in the 10% saline solution will be 0.1 * x cc = 0.1x cc.
Since the resulting solution is 20% saline, the total amount of saline in the mixture will be 0.2 * (50 + x) cc. Setting up the equation, we have 30 + 0.1x = 0.2 * (50 + x).
Simplifying the equation, we get 30 + 0.1x = 10 + 0.2x. Solving for x, we find that x = 200 cc.
