Answer:
The correct answer is nausea and breathing trouble.
Explanation:
In the given example, the client is receiving 1000ml saline with 40mEq of KCl (Potassium Chloride) and we are looking for symptoms of hyperkalemia. Hyperkalemia is a disease observed when there is excess amounts of potassium present in the bloodstream. It's first and most important symptoms are tiredness, nausea and vomiting, breathing trouble and chest pain so these are the findings that will be initially noted in the client if they have hyperkalemia.
I hope this answer helps.
Answer:
17.5 g of manganese-56
Explanation:
Now we have to use the formula;
N/No= (1/2)^t/t1/2
Where
N= mass of manganese-56 left after time (t) = ????
No= initial mass of manganese-56 present = 20 g
t= time taken for N mass of manganese-56 to remain = 7.8 hours
t1/2= half-life of manganese-56 = 2.6 hours
Then we substitute values;
N/20 = (1/2)^7.8/2.6
N/20 = (1/2)^3
N= (1/2)^3 ×20
N= 2.5 g of manganese-56
Mass of manganese-56 that has disappeared after 7.8 hours= 20 -2.5 = 17.5 g of manganese-56
