The nurse is drawing blood from a client's peripheral vein for laboratory specimens. Which of the following are correct nursing actions? Select all that apply.
Correct Answer: A,C
Rationale: A tourniquet left on too long (A) can cause hemoconcentration, so it should be removed after 1 minute. Pulsating blood (C) indicates arterial puncture, requiring immediate needle withdrawal and pressure to prevent hematoma. Wet alcohol (B) can cause hemolysis, and the ventral wrist (D) is a risky site due to nerves and arteries. Vigorous shaking (E) damages blood cells, so gentle inversion is preferred.
