Quiz 10: Venipuncture Procedures
Identification is done by looking at patient's armband indicating the first and last name of the patient, medical record number, and hospital identification number. The arm-band may also include room number of the patient, bed number and doctor's name. Most importantly an arm-band of a patient must include name, identification number, birth date and address. Name, birth date, address, and identification number of the patient can be asked verbally from the patient. If the hospitalized patient is semi-conscious or comatose, then a nurse, relative or friend must be asked to recognize the patient by clarifying the name, address, identification number, and address of the patient. Hence, the options b, c and d are incorrect. Identifying patient on the basis of charts or equipment placed next or on the bed of the patient must be strictly avoided, because sometimes the tags or charts placed on the bed-side are not changed timely after the patient is discharged. Hence, the correct answer is option .
If a patient is comatose, then the identifier must consult the nurse, relative, and friend. It must confirm the date of birth, patient's name, address, medical record number, and hospital identification number. All the collected information must then be compared with the data present on the requisition form, so as to reconfirm the patient's identity. Any kind of discrepancy, if present, must be reported to the supervisor. The person who verifies the patient's identity must be documented. In case of severely burnet comatose patients, patient identification can be done on the basis of bed label or tag or chart. These are the rare cases and are subjected to additional institutional policies. A nurse confirmation and proper documentation are also necessary. Hence, the options a, b and c are incorrect. Name cards on the bed or on the doors must never be used for the identification of a patient. Many times these tags are not replaced by the new ones after the discharge of the previous patient. Hence, the correct answer is option .
Venipuncture is the process of drawing blood from a vein to collect blood specimens for laboratory testing purposes. The most common sites for venipuncture are in the antecubital area, which is present just below the bend of the elbow. Antecubital area is the area where medial cubital, cephalic, and basilic veins are most prominent and are present in proximity to the skin-surface. In order to prevent artery or nerve puncturing during the venipuncture procedure the median vein is the foremost choice. The blood can be easily drawn from this site and it is less painful and less prone to injury. Hence, the options a, c and d are incorrect. The second choice will be of cephalic vein that lies on the outer edge of the hand. Venipuncture is the basilic vein, which is present close to the median nerve and the brachial artery. If all the three veins are inaccessible, then veins on dorsal side of the wrist or hand are considered for venipuncture procedure. Hence, the correct answer is option .
