Bác sĩ khám bệnh nhân.

Yes. This sentence follows the basic Vietnamese word order:

subject + verb + object

So in:

Bác sĩ khám bệnh nhân.

• bác sĩ = the doctor / doctors
• khám = examines / examine
• bệnh nhân = the patient / patients

Because Vietnamese usually relies on word order, bác sĩ is understood as the doer of the action, and bệnh nhân is the receiver of the action.

If you reversed them:

Bệnh nhân khám bác sĩ.

that would mean The patient examines the doctor, which is a very different situation.

Vietnamese usually does not require articles like the, a, or an.

So bác sĩ can mean:

• a doctor
• the doctor
• doctors

And bệnh nhân can mean:

• a patient
• the patient
• patients

The exact meaning depends on context.

So Bác sĩ khám bệnh nhân could mean:

• The doctor examines the patient
• A doctor examines a patient
• Doctors examine patients

In a real conversation, context usually makes the intended meaning clear.

You often do not know from the sentence alone. Vietnamese nouns usually do not change form for singular vs. plural.

So:

• bác sĩ can be singular or plural
• bệnh nhân can be singular or plural

If a speaker wants to make plurality clearer, they can add other words, for example:

• các bác sĩ = the doctors
• những bệnh nhân = patients / the patients

But without those markers, the sentence stays neutral.

Vietnamese verbs do not change form the way English verbs do. The verb khám stays the same.

Time is usually understood from:

• context
• time words
• aspect markers

So Bác sĩ khám bệnh nhân by itself can be understood as:

• The doctor examines the patient
• The doctor is examining the patient
• sometimes even a general statement like Doctors examine patients

If you want to make time clearer, Vietnamese can add words such as:

• đang for ongoing action: Bác sĩ đang khám bệnh nhân. = The doctor is examining the patient.
• đã for completed/past action: Bác sĩ đã khám bệnh nhân. = The doctor examined / has examined the patient.
• sẽ for future: Bác sĩ sẽ khám bệnh nhân. = The doctor will examine the patient.

Here khám means to examine, especially in a medical context.

So Bác sĩ khám bệnh nhân means the doctor is medically examining the patient.

This is not the same as a general English verb like see in The doctor sees the patient, although in translation English may sometimes use see naturally. The Vietnamese verb is more specifically about examination.

Related expressions:

• khám bệnh = examine illness / do a medical checkup
• khám sức khỏe = do a health check
• đi khám = go for a medical examination

It is a two-syllable Vietnamese noun written as two separate written units:

bệnh nhân

But grammatically, it functions as one noun meaning patient.

Literally:

• bệnh = illness / sick
• nhân = person (in compounds of Sino-Vietnamese origin)

So together, bệnh nhân means something like sick person, but in normal usage it simply means patient.

This is very common in Vietnamese: many compounds are written with spaces even though they work as a single lexical item.

Not in this sentence.

Vietnamese classifiers are often used with nouns when you are being specific about number, for example:

• một bác sĩ = one doctor
• một bệnh nhân = one patient

But in a simple general sentence like:

Bác sĩ khám bệnh nhân.

no classifier is needed.

If you wanted to specify individuals, you might say:

• Một bác sĩ khám một bệnh nhân.

That means One doctor examines one patient or A doctor examines a patient.

Yes. Because there are no articles and no tense markers, the sentence can sound fairly general.

Depending on context, it may mean:

• a specific event: The doctor is examining the patient
• a habitual or professional fact: Doctors examine patients

Vietnamese often leaves this open unless the speaker adds more detail.

For a more general statement, context or extra words help:

• Bác sĩ khám cho bệnh nhân.
• Các bác sĩ khám bệnh nhân mỗi ngày. = Doctors examine patients every day.

A rough pronunciation guide is:

bác sĩ khám bệnh nhân
≈ bak see kham benh nyun

But that is only approximate. The tones are very important:

• bác — rising tone
• sĩ — creaky broken rising tone
• khám — rising tone
• bệnh — heavy low tone
• nhân — level tone

A few pronunciation notes:

• bác ends with a final -c, so it stops sharply.
• sĩ has a tone that English speakers often find difficult.
• bệnh has the nh ending, and the vowel is not exactly like English.
• nhân begins with nh, which sounds somewhat like the ny in canyon.

If you are learning pronunciation, it is best to hear this from a native speaker or audio source, because tones matter a lot in Vietnamese.

Normally, no. Vietnamese depends heavily on word order, so:

Bác sĩ khám bệnh nhân
is understood as
The doctor examines the patient

because the first noun is the subject and the second is the object.

However, the sentence is still somewhat open in other ways:

• singular or plural?
• present or general meaning?
• specific or non-specific?

So the roles are clear, but the broader interpretation may depend on context.
