Which of the following accommodations should a phlebotomist make to increase a patient's comfort for venipuncture?

Choice A Reason:
The patient's condition is a critical factor as it can influence the ease of blood collection and the choice of collection site. For example, a dehydrated patient may have less accessible veins. Patient age is also important; pediatric and geriatric patients may require different approaches due to vein size and fragility. The blood volume required for testing must be considered to ensure sufficient sample size without compromising patient safety, adhering to guidelines that limit blood collection to a certain percentage of the patient's total blood volume.

Choice B Reason:
While patient height and gender may influence the choice of blood collection site, they are not as critical as the factors listed in choice A. Patient medications are important to consider, as some medications may affect coagulation or the integrity of the sample.

Choice C Reason:
The ordering physician's preferences may be considered, but they are not a primary factor in the method of collection. The number of tests ordered and the diagnosis can influence the volume of blood needed but are secondary to the patient's condition and safety considerations.

Choice D Reason:
The time of day and the timing of the specimen collection can be important for certain tests that are time-sensitive or influenced by diurnal variations. The test status, whether routine or stat, may affect the urgency of collection but not necessarily the method of collection.

Choice A Reason:
Arm restraints are typically used to prevent patients from moving, particularly in pediatric or psychiatric settings where the patient may not voluntarily keep still. However, they are not specifically designed for stabilizing the arm during venipuncture procedures.

Choice B Reason:
A blood pressure cuff can be used as a substitute for a tourniquet to engorge the veins before venipuncture, but it is not designed to stabilize the arm during the procedure. Its primary function is to measure blood pressure, not to provide stability.

Choice C Reason:
A phlebotomy wedge is a device specifically designed to support and stabilize a patient's arm during venipuncture. It helps to maintain the arm in a comfortable and steady position, which can be particularly helpful for patients with tremors or for those who have difficulty holding their arm still.

Choice D Reason:
A phlebotomy cart is used to transport and organize phlebotomy supplies. While it is an essential piece of equipment for a phlebotomist, it does not play a role in stabilizing a patient's arm during venipuncture.
