Which of the following actions can result in a violation of patient privacy?
Submitting laboratory results to the representative for workers' compensation
Discussing laboratory results with a patient's partner
Providing diagnosis codes to a patient's insurance company
Printing a patient's full name on the specimen label
The Correct Answer is B
Choice A Reason:
Submitting laboratory results to the representative for workers' compensation is generally not a violation of patient privacy. This action is often necessary as part of the claims process and is typically done with the patient's consent or as mandated by law.
Choice B Reason:
Discussing laboratory results with a patient's partner without the patient's explicit consent is a violation of patient privacy. Confidentiality is a fundamental principle in healthcare, and disclosing health information to unauthorized individuals, including family members, breaches that confidentiality.
Choice C Reason:
Providing diagnosis codes to a patient's insurance company is a standard procedure and is not considered a violation of patient privacy. This information is necessary for the insurance company to process claims and provide coverage for medical services.
Choice D Reason:
Printing a patient's full name on the specimen label is standard practice and does not violate patient privacy. This is done to ensure that the specimen is correctly identified and matched to the patient, which is critical for accurate diagnosis and treatment.

Correct Answer is D
Explanation
Choice A reason:
The high pressure in the arterial system is not a factor in the filling of blood collection tubes during venipuncture. Arterial blood is not typically collected using evacuated tubes; these are used for venous blood collection, where the pressure is lower.
Choice B reason:
While the venous system does have pressure that aids in blood flow, it is not the high pressure that causes blood collection tubes to fill. Venous pressure is relatively low compared to arterial pressure, and on its own, it is not sufficient to fill the vacuum tubes used in venipuncture.
Choice C reason:
The positive pressure created by the tourniquet can help engorge the veins, making them easier to access, but it does not directly cause the blood collection tubes to fill. The tourniquet's role is to assist in vein visualization and palpation rather than in the filling of the tube.
Choice D reason:
The negative pressure within the tube is the correct factor that causes blood collection tubes to fill during venipuncture. When the needle punctures the patient's vein and then the tube stopper, the vacuum in the tube pulls blood into it until the vacuum is exhausted or the tube is filled. This is why it is essential not to allow the tube contents to contact the stopper, as backflow into the venous system can cause adverse reactions.
Correct Answer is D
Explanation
Choice A reason:
Heparin is an anticoagulant, not a clot activator. It works by inhibiting thrombin and preventing the conversion of fibrinogen to fibrin, thus preventing clot formation. It is commonly found in green-top tubes and is suitable for collecting plasma samples for tests like electrolyte levels and coagulation studies.
Choice B reason:
Oxalate is also an anticoagulant that prevents clotting by precipitating calcium. It is not used to promote clot formation but rather to maintain a blood sample in a non-coagulated state for various tests.
Choice C reason:
Citrate functions similarly to heparin and oxalate as an anticoagulant. It chelates calcium ions in the blood, inhibiting the coagulation process. Citrate is often used in blue-top tubes and is ideal for collecting plasma samples for coagulation studies.
Choice D reason:
Silica is a clot activator. It is commonly used in serum separator tubes (SSTs) with a gold or red speckled top. The silica particles provide a surface for the rapid formation of the clot, allowing for the separation of serum from the blood cells. This is essential when serum is needed for testing.
