W przychodni pielęgniarka pobiera krew rano.

Because after w when it means in / at a place, Polish usually uses the locative case.

The basic dictionary form is przychodnia = clinic / outpatient clinic.
After w, it changes to przychodni:

• przychodnia — nominative
• w przychodni — locative

So:

• W przychodni = in / at the clinic

This is a very common pattern:

• w szkole = in school
• w pracy = at work
• w kuchni = in the kitchen

Przychodnia usually means a clinic, medical clinic, or outpatient medical center.

It is not quite the same as szpital (hospital). A przychodnia is typically a place you go for appointments, checkups, tests, or routine care, without staying overnight.

So w przychodni suggests something like:

• at the clinic
• in the medical clinic
• at the outpatient center

In this sentence, krew is the direct object, so it is in the accusative case.

The verb pobierać here means to draw / collect / take, so the nurse is taking blood.

For the noun krew, the accusative singular is still krew, so it looks the same as the basic form.

Important forms:

• krew — nominative
• krew — accusative
• krwi — genitive / locative / dative
• krwią — instrumental

So even though the case changes functionally, the word itself does not change in this sentence.

Here pobiera krew is the natural medical expression for drawing blood or taking a blood sample.

The verb is pobierać (imperfective), and pobiera is:

• 3rd person singular
• present tense

So literally it is something like:

• the nurse takes blood
• more naturally in English: the nurse draws blood

In medical Polish, pobierać krew is a standard collocation.

Polish present tense can be used in a few ways, just like English present tense.

In this sentence, it most naturally suggests:

• a habitual action
• a routine
• a general statement

So the sentence can mean something like:

• At the clinic, the nurse draws blood in the morning.
• At the clinic, the nurse takes blood samples in the morning.

Depending on context, Polish present tense can also sometimes describe something happening right now, but with rano it often sounds more like a routine or scheduled action.

Because rano is already an adverb, and it means in the morning / in the morning hours / early in the day.

So you simply say:

• rano = in the morning

You do not add w before it.

Compare:

• rano = in the morning
• wieczorem = in the evening
• nocą = at night

There is also rankiem, which also means in the morning / early in the morning, but rano is the most common everyday choice.

Yes. Polish word order is much more flexible than English word order because case endings show grammatical roles.

The sentence:

• W przychodni pielęgniarka pobiera krew rano.

is perfectly correct. It puts a little emphasis on where the action happens first: at the clinic.

Other possible orders include:

• Pielęgniarka pobiera krew rano w przychodni.
• Rano pielęgniarka pobiera krew w przychodni.
• Pielęgniarka rano pobiera krew w przychodni.

These versions all mean roughly the same thing, but the emphasis changes slightly.

A useful rule of thumb:

• the first part of the sentence often gets extra focus
• the last part can also sound highlighted or like new information

Yes. Pielęgniarka is the female word for nurse.

The masculine form is:

• pielęgniarz = male nurse

Polish job nouns are often gendered, so this sentence specifically refers to a female nurse.

If you already know from context that the nurse is female, pielęgniarka is exactly the right word.

No. In this sentence w przychodni means in / at the clinic, so it describes location.

If you want to say to the clinic, Polish normally uses:

• do przychodni = to the clinic

So compare:

• Jest w przychodni. = He/She is at the clinic.
• Idzie do przychodni. = He/She is going to the clinic.

That is an important distinction:

• w + locative = location
• do + genitive = movement toward a place

Yes, it is grammatical and understandable. It sounds like a straightforward statement about what happens at a clinic.

A native speaker might also choose slightly different word orders depending on what they want to emphasize, for example:

• Pielęgniarka pobiera krew rano w przychodni.
• Rano w przychodni pielęgniarka pobiera krew.

But your original sentence is fully natural and correct.
