How does be mahz-e work in this sentence with residan?
be mahz-e means 'upon' or 'immediately after'. As you are learning in this lesson, formal Farsi often pairs it with the Ezafe and a long infinitive (the dictionary form of a verb acting as a noun). Here, residan (to arrive) acts as the noun 'arrival'. Together with the Ezafe, be mahz-e residan-e bimar literally translates to 'upon the arrival of the patient'.
Can be mahz-e be used with conjugated verbs instead of the infinitive residan?
Yes, but you need to add inke to introduce a full clause. You could say be mahz-e inke bimar resid (as soon as the patient arrives). Using the infinitive without inke, as seen in this sentence, sounds more formal, concise, and professional, making it very common in written instructions or medical contexts.
Why is the direct object marker ra placed all the way after u?
The marker ra always attaches to the very end of the complete noun phrase it modifies. The direct object being checked here isn't just 'pulse and breathing', but rather 'the pulse and breathing of him' (nabz o tanaffos-e u). Because u is the final word in that connected possessive chain, ra must follow it.
Why is there an Ezafe on tanaffos but not on nabz?
The word nabz (pulse) is connected to tanaffos (breathing) by the conjunction (pronounced here). Conjunctions do not take the Ezafe. However, the Ezafe on is what links the entire combined concept of 'pulse and breathing' to the possessor pronoun (his/her), creating the meaning 'his pulse and breathing'.
