Which of the following is an appropriate technique when preparing a site for venipuncture after applying antiseptic?

Wipe with clean gauze.

Allow to air dry.

Blow on the site.

Wave hands over the site.

Answer and Explanation

The Correct Answer is B

Choice A Reason:

Wiping the site with clean gauze after applying antiseptic is not recommended. This action can remove the antiseptic before it has had sufficient time to disinfect the area, potentially reintroducing bacteria to the site and increasing the risk of contamination.

Choice B Reason:

Allowing the site to air dry after applying antiseptic is the appropriate technique. This ensures that the antiseptic has enough contact time to effectively reduce microbial flora on the skin. Air drying also prevents any potential irritation that might be caused by wiping or touching the site before the venipuncture.

Choice C Reason:

Blowing on the site to speed up drying is not an appropriate technique. This can introduce bacteria from the breath to the clean site, which could lead to contamination and increase the risk of infection.

Choice D Reason:

Waving hands over the site is not an appropriate technique either. This action could potentially contaminate the site with bacteria or particles from the skin or the environment. It is also less effective in ensuring that the antiseptic has dried completely.

Correct Answer is B

Explanation

Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.

Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.

Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.

Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.

A. Ask the patient if they are okay in a loud voice. B. Perform the head-tilt-chin-lift maneuver. C. Administer two rescue breaths. D. Look, listen, and feel for breathing movements.

Correct Answer is A

Explanation

Choice A reason:
When encountering a patient who appears motionless and cyanotic, the first action should be to assess their level of consciousness. Asking loudly if they are okay can help determine if the patient is responsive or unresponsive. If there is no response, this indicates that the patient may be unconscious and requires further immediate assessment and potential intervention.

Choice B reason:
The head-tilt-chin-lift maneuver is used to open the airway of an unresponsive patient who is not suspected of having a spinal injury. However, this is not the first step. Before performing any maneuvers, it is essential to determine the patient's level of consciousness and whether they are breathing.

Choice C reason:
Administering rescue breaths is part of the process of cardiopulmonary resuscitation (CPR), which is only initiated after confirming that the patient is unresponsive and not breathing normally. This step comes after checking for responsiveness and breathing.

Choice D reason:
Looking, listening, and feeling for breathing movements is part of the assessment to determine if the patient is breathing normally. This is done after establishing unresponsiveness but before initiating CPR. It is a critical step, but it follows after confirming that the patient does not respond to verbal stimuli.
