After anchoring the vein, which of the following actions should the phlebotomist take next?
Clean the site.
Perform the procedure.
Examine the needle.
Reapply the tourniquet.
The Correct Answer is B
Choice A reason:
Cleaning the site is a step that should be completed before anchoring the vein. The site should be cleaned with an antiseptic to reduce the risk of infection. Once the vein is anchored, cleaning the site again could displace the vein and compromise the anchoring.
Choice B reason:
After anchoring the vein, the phlebotomist should perform the procedure, which involves inserting the needle into the vein at the appropriate angle. Once the needle is in place and blood is seen in the tubing, the phlebotomist can proceed to collect the necessary amount of blood into the vacutainers or syringe.
Choice C reason:
Examining the needle is not the next step after anchoring the vein. The needle should be examined before the procedure begins to ensure it is the correct size and gauge for the venipuncture and that there are no defects.
Choice D reason:
Reapplying the tourniquet is not necessary at this point in the procedure. The tourniquet should already be in place to engorge the vein, making it easier to anchor and access. Reapplying it could cause discomfort or even disrupt the already anchored vein.

Correct Answer is A
Explanation
Choice A Reason:
For blood donation, a 16- to 18-gauge needle is typically used because it is large enough to allow the rapid flow of blood without causing hemolysis (destruction of red blood cells). The larger gauge needle also helps in minimizing the time the donor has to spend during the donation process. Using a needle that is too small could slow down the blood flow and potentially damage the blood cells, which is not ideal for the recipient of the blood donation.
Choice B Reason:
A 19- to 21-gauge needle is commonly used for routine venipuncture but is not ideal for blood donation. These needles are smaller than the 16- to 18-gauge needles and would not facilitate the quick collection of the volume of blood typically required for a donation. They are more suitable for collecting blood samples for testing rather than for donation purposes.
Choice C Reason:
A 22- to 24-gauge needle is even smaller and is often used for patients with smaller veins, such as children or elderly patients. These needles would not be appropriate for blood donation as they could significantly slow the blood flow and increase the donation time, which could be uncomfortable for the donor.
Choice D Reason:
A 25- to 28-gauge needle is the smallest size commonly used in medical practice and is suitable for patients with extremely small or fragile veins. These needles would be impractical for blood donation due to their small size, which would not allow for the efficient flow of blood required for a donation.
Correct Answer is C
Explanation
Choice A Reason:
Assault is an act that threatens physical harm to a person, whether or not actual harm is done. It is an intentional act where the assailant engages in an action that makes the victim fear an imminent harmful or offensive contact. It does not necessarily involve actual physical contact.
Choice B Reason:
Battery is the intentional and wrongful physical contact with a person without their consent that results in some injury or offensive touching. Unlike negligence, battery requires intentional conduct that results in harmful or offensive contact with another person.
Choice C Reason:
Negligence is the failure to take proper care in doing something, which leads to damage or injury to another person. It involves a breach of duty of care that results in harm. Negligence is not intentional; it is a legal concept that implies that a reasonable level of care was not met under the circumstances.
Choice D Reason:
Fraud is a deliberate deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud involves intentional misrepresentation or concealment of an important fact upon which the victim is meant to rely, and does so to the victim's detriment. This is different from negligence, which does not involve intentional deceit.
