Setelah rawat jalan selesai, perawat melepas infus lalu mengantar pasien ke ruang tunggu.

Setelah means after and introduces a time clause.

In Setelah rawat jalan selesai, ..., it sets up the background time first: after the outpatient treatment/check-up was finished.

A very common Indonesian pattern is:

• setelah + clause, main clause
• After + clause, main clause

So the sentence structure is:

• Setelah rawat jalan selesai, ...
• After the outpatient treatment was finished, ...

You can also often move that setelah clause to the end, although the original version is very natural.

Rawat jalan is a fixed medical expression meaning outpatient care/treatment.

It contrasts with rawat inap, which means inpatient care or hospitalization.

Literally:

• rawat = to treat / care for
• jalan = walk / go / run

But you should learn rawat jalan as a set phrase, not by translating each word separately. In hospital language, it refers to treatment where the patient does not stay overnight.

Both are possible, but they are slightly different in feel.

• rawat jalan selesai = the outpatient treatment is finished / finished
• rawat jalan sudah selesai = the outpatient treatment is already finished / has finished

Indonesian often leaves out words like sudah when the context is clear. So selesai by itself already gives the idea of completion.

Also, selesai can behave a bit like an adjective (finished, complete) and also like part of a predicate. Indonesian does not always need a verb equivalent to to be.

So:

• rawat jalan selesai literally feels like outpatient treatment finished
• natural English: the outpatient treatment was finished

Because Indonesian usually does not use a separate verb like to be in sentences like this.

English needs:

• The treatment was finished

Indonesian can simply say:

• Rawat jalan selesai

This is very normal. Indonesian often makes predicates without is/are/was/were.

Other examples:

• Pintunya terbuka = The door is open
• Dia sakit = He/She is sick
• Rapat selesai = The meeting is finished

So the lack of was is just a normal difference between Indonesian and English.

Lepas by itself often means loose, free, detached, or can function as a base related to releasing/removing.

Melepas is the active verb formed with the meN- prefix, and here it means to remove, to take off, or to detach.

So in this sentence:

• perawat melepas infus = the nurse removes the IV

This is a very common pattern in Indonesian:

• base/root: lepas
• active verb: melepas

Other similar examples:

• pakai → memakai
• bawa → membawa
• antar → mengantar

In Indonesian, infus usually refers to an IV drip, IV line, or the intravenous setup attached to a patient.

So when the sentence says:

• perawat melepas infus

it means the nurse removes the patient’s IV.

In real-life usage, infus can refer a bit broadly to the IV equipment/tube/line, not necessarily in a highly technical distinction-by-distinction way.

Lalu means then, after that, or and then.

It links two actions in sequence:

1. perawat melepas infus
2. mengantar pasien ke ruang tunggu

So the sentence shows the order clearly:

• first, the nurse removes the IV
• then, the nurse escorts the patient to the waiting room

Similar connectors include:

• kemudian = then, afterward
• terus = then/next/continue on (more conversational in many contexts)

In this sentence, lalu is a natural, neutral choice.

Because the same subject applies to both verbs.

In:

• perawat melepas infus lalu mengantar pasien ke ruang tunggu

the subject perawat belongs to both:

• melepas
• mengantar

So it works like:

• The nurse removed the IV and then escorted the patient to the waiting room

Indonesian often avoids repeating the subject when it is still the same and clearly understood.

If you repeated it, it would sound more explicit and usually less natural unless you wanted emphasis:

• perawat melepas infus lalu perawat mengantar pasien ...

That is grammatical, but unnecessary in normal speech.

Mengantar means to accompany, to escort, or to take someone somewhere.

In this sentence:

• mengantar pasien ke ruang tunggu
• escort/take the patient to the waiting room

This is different from membawa, which means to bring/carry/take something or someone, with more focus on transporting.

A simple comparison:

• mengantar pasien ke ruang tunggu = escort the patient to the waiting room
• membawa pasien ke ruang tunggu = take/bring the patient to the waiting room

Both can work in some situations, but mengantar is especially natural when a staff member accompanies a person to a destination.

Because ke shows movement toward a destination, while di shows location.

• ke ruang tunggu = to the waiting room
• di ruang tunggu = in/at the waiting room

Since the nurse is escorting the patient to that place, ke is the correct preposition.

Compare:

• Pasien menunggu di ruang tunggu = The patient waits in the waiting room
• Perawat mengantar pasien ke ruang tunggu = The nurse escorts the patient to the waiting room

Because Indonesian does not use articles the way English does.

English requires choices like:

• a nurse
• the nurse
• a patient
• the waiting room

Indonesian usually just uses the noun:

• perawat
• pasien
• ruang tunggu

The exact meaning—whether it is a nurse, the nurse, the patient, etc.—comes from context.

This is one of the biggest differences from English. Indonesian often leaves definiteness unstated unless it really matters.

Indonesian verbs do not change form for tense the way English verbs do.

So:

• melepas
• mengantar

do not themselves mean specifically removes, removed, or will remove. The time is understood from context.

In this sentence, the sequence of events and the situation make it natural to interpret it as a completed event, so in English we often translate it in the past:

• After the outpatient treatment was finished, the nurse removed the IV and then escorted the patient to the waiting room.

If Indonesian wants to make time clearer, it can add time words such as:

• sudah = already
• tadi = earlier
• kemarin = yesterday
• akan = will

But these are not always necessary.

Some rearrangement is possible, but the original order is very natural.

Original:

• Setelah rawat jalan selesai, perawat melepas infus lalu mengantar pasien ke ruang tunggu.

You could also say:

• Perawat melepas infus lalu mengantar pasien ke ruang tunggu setelah rawat jalan selesai.

This is still understandable, but the original is often clearer because it gives the time/background first.

Putting setelah rawat jalan selesai at the beginning helps the listener process the sequence more easily. Indonesian often likes this kind of setup: background first, main actions after.

Yes, Indonesian often forms noun phrases by putting nouns together, and ruang tunggu is a very common example.

• ruang = room/space
• tunggu = wait

Together:

• ruang tunggu = waiting room

This is similar to many Indonesian compounds where the first word is the main noun and the second word describes its function.

Other examples:

• kamar mandi = bathroom
• rumah sakit = hospital
• meja makan = dining table

So ruang tunggu is a normal and very useful compound to learn as one unit.
