Dear, Soul!!

Last night I had a hard time sleeping because I kept thinking about how it was today when I met Farhan. But I finally decided to go through with it, how long will I avoid Farhan? This kind of me would constantly be awkward with Farhan if I kept thinking about it.

"Today at ten can?" The message Farhan sent.

"Yes could be brother.." My reply.

"We'll see you there, yeah, I'll share the location.."

"Yes sis.."

It's almost ten o'clock now, so Farhan might be there waiting while I'm still waiting for Annisa at home.

"Where is it? A moment ago awaited not appear" I began to annoy waiting.

This morning Annisa came home early, after she finished the Fajr Prayer she did not go back to sleep. I told him I was going to meet Farhan at ten and he agreed but until now there was no sign of Annisa coming.

"Nis, where are you?" The short message I sent. I waited a while but there was no reply.

I tried to reach him.

"Hello Wa, I don't think I can come with you" he said after answering my phone.

"Why?"

"Children from other groups already want to buy the material now, I can't if later have to buy the material themselves"

"Yes, but this is what he promised Farhan"

"You can't go there by yourself? This is why I asked the other children about the task and they were a little confused"

"So I met Farhan's own brother?"

"Yes. Sorry I can't go with you. But if the purchase material quickly finished later I followed, but if not later I will go home you ask for a lesson ya.."

"Relatedly.."

"Yes Wa.. Don't be angry, I also have no other choice, if tomorrow we pass the door response but the material is not the same if we still can not join the practicum.."

"Hem yes.. But if the purchase material has been completed quickly follow ya.."

"Ashiaap's chat.."

"Jude, I want to walk.."

"Be careful.."

Call ended.

I finally walk myself to the place where the location has been given the same Farhan earlier.

"Where's old? You're not a stray, are you?" A short message Farhan sent.

"No, I'm sorry I'm late.."

"What's wrong, or do I want to pick it up?"

"Don't, brother, just let me get there.."

"So, be careful on the road."

It's a good thing it's the weekend so I'm not stuck. I made a deal with Farhan at ten and I left at ten for seven minutes, if I got stuck I would be late.

I arrived at the cafe that Farhan had determined, I saw Farhan standing outside.

"Sorry brother I'm late" I said running to Farhan.

"Thank God you've arrived, I think you've gone all the way here"

"Hehe no, I just called this address to the taxi driver and I was immediately ushered here.."

"Hem, it's better if next time there's an appointment like this I'll just pick you up.."

"What sis, I'll be taking nicotine later.."

"It's even more troublesome if you're worried like this Salwa..."

Somehow I blushed a little at Farhan who was worried about me.

"I just need to adapt to the same area here, later will also get used to it.."

"Ah yes, if there is no task you can walk where it is so that you can know the area here. I'll take a walk let's not muter-muter first if find the address"

"I'll wait for you, I'll let you go.."

"Sorry to trouble you, brother.."

"What's wrong, yaudah let's go in.." Take Farhan. I stepped in.

I opened the note and showed my duty.

"Oh dose calculation, what do you not understand?"

"I this is brother.. Actually it has been explained how to calculate the dose for adults over twenty years, eight years and adek baby, but the problem is created by the same lecturer is uncertain of his age. I'm so confused as to how to calculate the dose"

"This let me see.."

Farhan looked serious reading about the lecturer.

"Oh, this you have to calculate the dose not based on the age of Salwa, but using the weight of the patient. You know, age is not the only way to determine the dose of a drug in a patient. In addition to age-related formulas such as Dilling, Young and Fried there is also the Thermich formula, which is the calculation of the dose based on the patient's weight. As you know, sometimes there are seven-year-olds for example but the weight is very light, also vice versa sometimes there are five-year-olds but the weight is excess than the weight of children in general." Evidently.

I looked at him confused.

"You don't know?"

I'm shaking. "If the formula of calculating the dose based on the age of all has been explained and I already know brother, but if the latter formula I do not know.."

"Hehehehe, the lecturer asked you to find out for yourself, open the book and learn for yourself. We are already in college, already a student so lessons like this must be sought again not all taught by lecturers"

"Oh that's it. I don't think about getting there, brother.."

Farhan gave a book. I picked it up and stared at the book for a moment.

"That's IReS Recipe Science, the basic book of Pharmacy. In the book, it was explained a lot about the calculation of the dosage of the drug puyer syrup and suspension. There are also some abbreviations in Pharmacy. You can also buy IMO to complete it.." Farhan.

"A what was that? I im?"

"IMO, Science of Medicines. But having one of them is enough that more books can be better to have more literature"

"Well, I'll try to find brother.."

"Yes.. So where was that about?"

I gave Farhan my notebook back.

"So this is the formula.." Farhan said pointing to the Thermich formula. "The calculation is the same as any other formula.."

I started trying to calculate the dose of the drug from my duty.

"Well now try to find the maximum dose in the Pharmacopeia, you have a Pharmacopeia, right?"

I'm nodding. I reached for the thousand-page tome, the third edition of the Pharmacopeia.

I was silent for a moment staring at the book.

"Why?" Ask Farhan.

"Is there no maximum dose?"

"Hem yes, not all drugs have a maximum dose of Salwa, there are drugs such as Paracetamol which only has a dose of Lazim. You can use the usual dose, different from the maximum dose that the dose should not be above the range, if the usual dose should even pass the usual dose, like how to do this"

Farhan started working on his dose calculation, he was very serious about it. I look at him once, charismatic once.

"Well how? Do you understand?" Farhan's question made my momentary daydream come to a realization.

"Eh I yes brother.." Reply stammered. I was almost caught looking at him.

"You why? Is there something you don't understand?" He asked me who saw me a little wrong.

"Not really, sister.." I try to control my expression.

"Okay, if so. Well like this Paracetamol Salwa if you look at the Pharmacopeia the indications must be using a language that you do not understand so you have to find out it"

"If Paracetamol I knew.. Paracetamol for fever and pain right?"

"Yaps is right, but the indication of fever is more dominant than the antinyerinya but still can to overcome pain. So if again headaches, teeth, and so on can use Paracetamol first for Firstline, Do not immediately eat anti-pain medication that levels are higher, use the lowest first for the beginning. Even though Paracetamol anti-fever is stronger than the anti-pain, but the anti-pain is strong enough to cure headaches and others as of yet the consumption of anti-pain above"

"Oh yes brother.. I understand"

Farhan continued to explain well.
