"Administer an injection" 或 "Give an injection" 都可以用来描述护士扎针。这两个短语都来自英语中的动词 "administer," 意思是 "给予（药物、输液等）"，以及 "injection," 意思是 "注射。"

下面是一些例句：

The nurse administered an injection of antibiotics to the patient. (护士给病人打了一针抗生素。)
Can you give me an injection? My arm is sore. (你能给我打针吗？我的胳膊疼。)
The nurse was trained to administer injections safely. (护士受过如何安全打针的培训。)
