Y tá đo nhiệt độ trước khi tiêm.

Y tá means nurse. It can refer to either a male or female nurse in everyday use.

A useful note for learners: in modern Vietnamese, điều dưỡng is also very common, especially in more formal or professional contexts. But y tá is still widely understood and often used in speech.

Vietnamese does not use articles like a, an, or the the way English does.

So Y tá can mean:

• a nurse
• the nurse

The exact meaning depends on context. In a standalone sentence like this, English may translate it as either one depending on the situation.

It literally means measure temperature.

In natural English, this is often translated as:

• take someone’s temperature
• check the temperature

In this medical context, nhiệt độ usually means body temperature, even though body is not explicitly stated.

Vietnamese often leaves out information that is obvious from context.

So in Y tá đo nhiệt độ trước khi tiêm, the patient is understood. A more explicit version could be:

• Y tá đo nhiệt độ cho bệnh nhân trước khi tiêm.
  = The nurse takes the patient’s temperature before giving an injection.

But if everyone already knows the nurse is dealing with a patient, the shorter version sounds perfectly natural.

Trước khi means before and is used before a verb or clause.

Pattern:

• trước khi + verb / clause

So:

• trước khi tiêm = before injecting / before giving the injection

This is different from using just trước, which is often used with nouns or time expressions.

Examples:

• trước bữa ăn = before the meal
• trước khi ăn = before eating

Tiêm means to inject or to give an injection.

In this sentence, because the subject is y tá (the nurse), tiêm is understood as administering the injection, not receiving one.

Depending on context, tiêm can relate to:

• giving a shot
• injecting medicine
• vaccination

So here it most naturally means give the patient an injection.

Yes. By default, the understood subject is still the nurse.

So the sentence means:

• The nurse takes the temperature before giving the injection.

Vietnamese often keeps the same subject across connected actions without repeating it.

If the subject changed, Vietnamese would usually make that clearer.

Because Vietnamese often omits objects when they are easy to understand from context.

Here, the listener can infer something like:

• tiêm thuốc = inject medicine
• tiêm cho bệnh nhân = inject the patient / give the patient an injection

So tiêm by itself is enough in many situations, especially in a medical setting.

Yes. It follows a very common pattern:

• Subject + verb + object + time clause

Breakdown:

• Y tá = subject
• đo = verb
• nhiệt độ = object
• trước khi tiêm = time clause

So the structure is very normal and natural.

Yes. Vietnamese often allows time phrases or clauses to move to the front.

For example:

• Trước khi tiêm, y tá đo nhiệt độ.

This means the same thing:
Before giving the injection, the nurse takes the temperature.

Putting trước khi tiêm first can slightly emphasize the timing.

No. Nhiệt độ simply means temperature in general.

It can refer to:

• body temperature
• room temperature
• water temperature
• weather temperature

But in a sentence with y tá and tiêm, the medical context makes body temperature the obvious meaning.

Yes, it is natural and correct.

A native speaker might also say slightly fuller versions, such as:

• Y tá đo nhiệt độ cho bệnh nhân trước khi tiêm.
• Trước khi tiêm, y tá đo nhiệt độ.

But the original sentence is already very natural, especially when the patient is understood from context.
