Experience the Quality With Free ASCP Phlebotomy Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

Ammonia is unstable and rises quickly at room temperature. To maintain accuracy, samples must be collected in heparin or EDTA tubes, placed on ice immediately, and tested within 15–30 minutes. Lipid profiles, HbA1c, and cholesterol do not require chilling. ASCP stresses recognition of temperature-sensitive analytes as an essential phlebotomy competency.

Comprehensive and Detailed Explanation:

Venipuncture should be avoided in the arm on the side of a mastectomy due to risk of lymphedema, infection, or compromised lymphatic drainage. Blood draws and blood pressure measurements can exacerbate swelling and harm tissue. If both sides are affected, alternative sites like hand veins or foot veins may be used with physician approval. ASCP guidelines highlight patient history as a key part of site selection to ensure safety and prevent complications.

Comprehensive and Detailed Explanation:

Nasopharyngeal swabs are standard for detecting respiratory viruses like influenza, RSV, and SARS-CoV-2. The swab must be inserted deep into the nasopharynx for adequate sample collection. Streptococcal pharyngitis requires a throat swab, and UTIs require urine. ASCP emphasizes correct source selection for non-blood specimens to ensure diagnostic reliability.

Non-Blood Specimens

Laboratory Operations

Comprehensive and Detailed Explanation:

The median cubital vein is large, superficial, and well anchored, making it less likely to roll during puncture. It is also located away from major arteries and nerves, reducing the risk of injury. For these reasons, it is the first choice vein in most patients. The cephalic is a second option, and the basilic is last choice due to its proximity to the brachial artery and median nerve. ASCP stresses vein hierarchy to ensure patient safety.

Comprehensive and Detailed Explanation:

For fecal occult blood testing, stool must be collected in a clean, dry, leakproof container. Contamination with urine or toilet water dilutes or alters hemoglobin concentration and may cause false negatives. Stool should not be frozen unless specifically directed by the testing method, as freezing may lyse cells or interfere with chemical reactions. Unlike urine cultures, sterile containers are not necessary unless specified for parasite or bacterial culture, but cleanliness is critical. Patients should be instructed carefully on how to collect the specimen to avoid cross-contamination, which could invalidate results. The phlebotomist or healthcare professional’s role includes providing patient education, labeling specimens accurately, and ensuring prompt transport to the lab. Stool samples may also be tested for parasites, pathogens, or chemical contents, each requiring adherence to collection instructions. ASCP emphasizes proper non-blood specimen handling as a key competency since incorrect procedures compromise diagnostic accuracy and may require recollection, causing delays and inconvenience for the patient.
