2. Perekani chithandizo chokwanira cha intravenous intravenous, venous access for phlebotomy, intramuscular jekeseni ndi malo a jekeseni wa intradermal.Njira zisanu ndi zitatu za mitsempha ya mitsempha imalola ophunzira kuchita venipunction m'malo onse a pulayimale ndi sekondale, kuphatikizapo kuyambika kwa IV ndi kuyika singano ya IV catheter.Mitsempha iyi imakhala ndi thumba lamagazi limodzi lokha, lomwe limatha kupereka magazi ofananirako ku mitsempha yonse panthawi imodzi.jakisoni mu mnofu akhoza kuchitidwa pa deltoid minofu ndi intradermal jekeseni malo kumtunda mkono.Khungu lofewa, lenileni komanso zizindikiro za mafupa achilengedwe m'derali zimathandiza kwambiri jekeseni wa intramuscular. Jakisoni wa intradermal pogwiritsa ntchito madzi osungunuka amatulutsa mawonekedwe akhungu pamalo osankhidwa kumtunda kwa mkono.
3. Chitsanzocho ndi chowonadi.Tsatanetsatane uliwonse pa zala zofewa, zosinthika zimaperekedwa chidwi, ngakhale zolemba zala zimatha kuwonedwa.Dzanja limatha kupindika kuthandiza ophunzira kugwiritsa ntchito luso lawo kutikita minofu.Khungu limasinthidwa ndipo limamva ngati khungu lenileni likagwiridwa.Pali kukhumudwa kodziwikiratu pochita venipuncture.
Chitsanzocho chimaponyedwa kuti chiberekenso mwatsatanetsatane chilichonse cha khungu kuti mkono uwoneke weniweni.Mavavu a venous amatha kuwonedwa ndipo amatha kumveka pakhungu.
4. Mitsempha yofananira yamagazi ndi khungu zitha kusinthidwa kwathunthu, ndipo njira yophunzitsira yosinthidwa ikhoza kupitiliza kugwiritsidwa ntchito pophunzitsa ntchito.Pogwiritsa ntchito bwino, malo omwewo amatha kubayidwa kambirimbiri.Zida zonse zosinthira zilipo kuti zigwiritsidwe ntchito mosavuta.
