Answer:
Volume of the solutions
This is the most important factor for her to control.
The answer is elements gain electrons. Oxidation reduction is elements lose electrons. And oxygen is added/lost can be a type of oxidation/reduction reaction.
Look out for angioedema (like hives but a deeper swelling due to an allergic reacrion), bleeding (such as intracranial, gastrointestinal and genitourinal hemorrhaging) and adverse reactions to drugs. Nausea, blood pressure spikes, severe headaches, acute hypertsnsion, etc are other signs of negative reacrions to iv t-pa as well.
Missing question: Express the salt concentration in kg/m³.
Answer is: the salt concentration is 9.8 kg/m³.
m(NaCl) = 9.8 g ÷ 1000 g/kg.
m(NaCl) = 0.0098 kg.
V(solution) = 1 L = 1 dm³.
V(solution) = 1 dm³ ÷ 1000 dm³/m³.
V(solution) = 0.001 m³.
d(solution) = m(NaCl) ÷ V(solution).
d(solution) = 0.0098 kg ÷ 0.001 m³.
d(solution) = 9.8 kg/m³.
