When a phlebotomy technician is introducing themselves after entering a patient's room, which of the following tones of voice should the technician use?

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.

Choice A Reason:
The age of the newborn is important for certain metabolic screenings, as some metabolites may not be present or at measurable levels immediately after birth. However, the requirement for the newborn to be at least 3 days old is not a standard for all blood spot collections for inborn errors of metabolism (IEM). Some screenings are performed within 24 to 48 hours after birth.

Choice B Reason:
While it is important that the circles on the filter paper are adequately filled to ensure there is enough blood for the test, the requirement for them to be at least half filled is not specified in the guidelines. The focus is usually on ensuring the blood spot is of the right size and properly saturated through the filter paper.

Choice C Reason:
The inclusion of the first drop of blood is not typically a requirement. In fact, the first drop is often wiped away to avoid contamination with tissue fluids that could affect the test results. Subsequent drops are used to fill the circles on the filter paper.

Choice D Reason:
The specimen must be completely dried before the test can be processed to prevent degradation or hemolysis of the blood sample. This is a critical step in the preparation of the sample for accurate testing of IEM. The drying process helps preserve the integrity of the metabolites to be analyzed.
