Which of the following actions is appropriate when transporting a specimen for ABG analysis?
Collecting the specimen in an SST
Placing the specimen in ice
Collecting the specimen in sodium citrate
Inserting the specimen in a light-resistant package
The Correct Answer is B
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:
Reporting the needlestick to the supervisor is an important step in the post-exposure protocol, but it is not the first action that should be taken. The immediate priority is to address the potential exposure to pathogens by cleansing the wound.
Choice B Reason:
Completing the blood draw is not the appropriate first action after a needlestick injury. The phlebotomist's health and safety take precedence, and the procedure should be paused to address the injury.
Choice C Reason:
Washing the area with soap and water is the first and most critical action to take after an accidental needlestick. This helps to remove any blood or pathogens that may have been introduced to the wound site. It is essential to do this immediately to reduce the risk of infection.
Choice D Reason:
Seeking immediate treatment is a necessary step, but it follows the initial cleansing of the wound. After washing the area, the phlebotomist should then report the incident and seek medical advice to assess the need for further treatment, such as post-exposure prophylaxis.
Correct Answer is A
Explanation
Choice A Reason:
When a patient is under "Contact Precautions," it is recommended that healthcare workers don a gown upon entering the patient's room. This is to prevent the spread of infection through contact with the patient or their environment. The gown should be removed before leaving the room to avoid contaminating other areas.
Choice B Reason:
While a face shield may be necessary for certain procedures, it is not specifically required for "Contact Precautions." The primary concern with contact precautions is preventing the transmission of infections through touch, not through droplets, which is what a face shield would protect against.
Choice C Reason:
Donning a mask is not a standard requirement for "Contact Precautions" unless there is a risk of droplet transmission. In this scenario, the precautions are specifically for contact, and therefore, a mask alone would not be sufficient.
Choice D Reason:
Gloves should be donned before any potential contact with the patient or their immediate environment, not just after cleaning and evaluating the venipuncture site. Gloves are a critical component of PPE when dealing with patients under "Contact Precautions."
