A phlebotomist is preparing to collect a blood specimen from a patient who has self-reported needle phobia. Which of the following actions should the phlebotomist take?
Encourage the patient to chew gum during the procedure.
Instruct the patient to lie supine during the procedure.
Place the patient's elbow joint at 90 degrees of flexion.
Warm the site for 10 minutes before venipuncture.
The Correct Answer is D
Choice A Reason:
Encouraging the patient to chew gum during the procedure may serve as a distraction, which can be helpful for some patients. However, this is not a widely recommended practice for reducing needle phobia. Distraction techniques can be beneficial, but they should be tailored to the individual patient's preferences and should not interfere with the procedure.
Choice B Reason:
Instructing the patient to lie supine during the procedure can help prevent fainting and reduce anxiety for some patients. This position is often used for patients who have a history of fainting or feel dizzy during blood draws. However, it is not specifically targeted at managing needle phobia.
Choice C Reason:
Placing the patient's elbow joint at 90 degrees of flexion is a standard practice to stabilize the arm and provide an optimal angle for venipuncture. While this is a necessary step in the procedure, it does not directly address the patient's needle phobia.
Choice D Reason:
Warming the site for 10 minutes before venipuncture is a technique used to enhance vein visibility and elasticity, making the venipuncture easier and potentially less painful. This can be particularly helpful for patients with needle phobia, as a smoother and quicker procedure may reduce anxiety and discomfort.

Correct Answer is A
Explanation
Choice A reason:
Inverting the tube 5 to 8 times ensures that the clot activator mixes thoroughly with the blood, promoting proper clotting. Setting the tube aside for 30 minutes allows sufficient time for the blood to clot before centrifugation. This is the recommended procedure to ensure that the serum is properly separated from the clot, resulting in a quality specimen suitable for testing.
Choice B reason:
Inverting the tube only 1 to 3 times may not be enough to mix the clot activator with the blood adequately, which could lead to incomplete clotting and potentially compromised test results. Additionally, setting the tube for 1 hour before centrifugation is longer than necessary and does not offer any advantage over the recommended 30 minutes.
Choice C reason:
Inverting the tube 2 to 4 times might not fully mix the clot activator with the blood, and setting it for only 15 minutes does not provide enough time for proper clot formation. This could result in a suboptimal separation of serum and clot, affecting the integrity of the test results.
Choice D reason:
Inverting the tube 8 to 10 times could potentially cause hemolysis or disruption of the blood cells due to excessive agitation. Setting the tube for 2 hours prior to centrifugation is not recommended as it could lead to serum degradation or other changes that may affect the test results.
Correct Answer is A
Explanation
Choice A Reason:
Taking the specimen temperature before 4 minutes is the correct procedure according to the Department of Transportation (DOT) guidelines. The DOT Rule 49 CFR Part 40 Section 40.65 states that the temperature of the specimen must be checked no later than four minutes after the employee has given the specimen. The acceptable temperature range is 32–38 °C/90–100 °F, which helps to verify the validity of the specimen.
Choice B Reason:
Taking the specimen temperature at 5 minutes is not within the DOT guidelines. The temperature must be taken before 4 minutes have passed to ensure the specimen's integrity and to comply with the regulatory requirements.
Choice C Reason:
At 15 minutes, the temperature check would be too late. The DOT guidelines specify that the temperature should be checked no later than four minutes after collection to ensure the specimen has not been tampered with and is within the acceptable temperature range.
Choice D Reason:
After 30 minutes, the temperature of the urine specimen would not reflect the body temperature at the time of collection, which is necessary for the validity of the test. This delay could allow for the temperature to fall outside of the acceptable range, potentially invalidating the specimen.
