Which of the following lancet positions should a phlebotomist recognize as part of the aseptic technique protocol?
Perpendicular to the fingerprint grooves
Parallel to the nail bed
Along the lateral portion of the first digit
Along the medial portion of the fifth digit
The Correct Answer is A
Choice A reason:
When performing a capillary blood collection, such as a fingerstick, the lancet should be positioned perpendicular to the fingerprint grooves. This orientation helps to ensure that the incision is made across the ridges of the fingerprint, which can facilitate a better blood flow and make it easier to collect an adequate sample without needing to squeeze the finger excessively, which could hemolyze the sample.
Choice B reason:
Positioning the lancet parallel to the nail bed is not recommended because it can result in a cut that runs along the length of the fingerprint grooves, which may not bleed as freely and could also be more painful for the patient.
Choice C reason:
Using the lancet along the lateral portion of the first digit is not part of the standard aseptic technique protocol for capillary blood collection. The first digit, or thumb, has a pulse and should generally be avoided because it can be more sensitive and is more prone to bruising.
Choice D reason:
The medial portion of the fifth digit, or the little finger, is also not a recommended site for capillary blood collection with a lancet. The little finger is typically smaller and may not provide an adequate site for blood collection, and similar to the thumb, it can be more sensitive and prone to injury.

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.
Correct Answer is C
Explanation
Choice A Reason:
A multipart requisition involves multiple copies of a paper form, which can be prone to errors due to manual entry, misplacement, or illegible handwriting. While it provides physical copies for various departments, it is not the most accurate method compared to digital solutions.
Choice B Reason:
A manual requisition is similar to a multipart requisition but typically consists of a single form. It carries the same risks of human error and does not offer the benefits of automated tracking and data entry that come with electronic systems.
Choice C Reason:
An automated requisition is considered the most accurate method for receiving orders for specimen collection. It reduces the risk of human error associated with manual data entry and allows for better tracking and integration with laboratory information systems. Automated systems can also provide immediate feedback if there is an issue with the order, such as a missing patient identifier or a test code.
Choice D Reason:
A verbal requisition is the least reliable method as it depends on the memory and communication skills of the individuals involved. It lacks the documentation and verification steps present in written or automated methods, making it susceptible to misunderstandings and errors.
