Which of the following is an appropriate technique for specimen collection?
Performing a heel stick on a 5-year-old patient
Performing a finger stick on a toddler patient
Performing a thumb stick on an infant
Performing a thumb stick on a 5-year-old patient
The Correct Answer is B
Choice A reason:
Performing a heel stick on a 5-year-old patient is not an appropriate technique. Heel sticks are typically used for infants, particularly newborns, to minimize discomfort and because their finger pads may not be fully developed for finger sticks. By the age of 5, a child's veins are usually developed enough for venipuncture, which is the preferred method.
Choice B reason:
Performing a finger stick on a toddler patient is an appropriate technique for specimen collection. This method is commonly used for children who are not yet old enough for venipuncture but have outgrown the heel stick method. The finger stick is performed on the palmar surface of the distal phalanx, usually of the middle or ring finger, and is considered safe and effective for collecting small blood samples in toddlers.
Choice C reason:
Performing a thumb stick on an infant is not an appropriate technique. The thumb has a pulse and is more sensitive, which can cause unnecessary pain and distress to the infant. Additionally, the thumb's size and increased movement make it a less suitable site for specimen collection in infants.
Choice D reason:
Performing a thumb stick on a 5-year-old patient is also not an appropriate technique. As with infants, the thumb's sensitivity and the presence of a pulse make it a less desirable site for blood collection. For a 5-year-old, venipuncture or a finger stick on a non-thumb finger would be more appropriate and less distressing.

Correct Answer is B
Explanation
Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.
Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.
Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.
Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.
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.
