Free
Multiple Choice
Answer:

Answer:

The venipuncture device is a device that is used for assessment of peripheral venous. It comes in a variety of gauges as well as diameters. The larger will be the number of gauge the smaller will be its diameter.
A venipuncture device is capped temporarily and is kept patent while using the medication lock. It is a sealed chamber, which allows intermittent access towards the vein.
Steps in venipuncture involve affixing the vein by holding the arm of the patient. The patient is then asked to form a fist so the veins are more prominent. Very swiftly at 30 degree angle or less the needle is introduced along the vein at the easiest angle of entry.
Hence, the options a, c and d are incorrect.
Once sufficient blood has been collected, the tourniquet is released before withdrawing the needle. After gently removing the needle from the venipuncture site gentle pressure is then applied to the site with a clean gauze or dry cotton-wool ball. The patient is advised to hold the cotton wool in place for a few minutes, with the arm extended and raised.
Hence, the correct answer is option img .

Free
Multiple Choice
Answer:

Answer:

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 img .
