Which of the following blood glucose monitors will need to have a quality control measurement daily?
All blood glucose monitors in use
Blood glucose monitors in use from the new office only
Blood glucose monitors in use from the old medical office only
None of the blood glucose monitors
The Correct Answer is A
Choice A reason:
Quality control measurements are essential for ensuring the accuracy and reliability of blood glucose monitors. According to best practices, all blood glucose monitors in use, regardless of their origin, should undergo daily quality control checks. This is to verify that the monitors are functioning correctly and providing accurate readings, which is crucial for patient care and treatment decisions.
Choice B reason:
Focusing only on the blood glucose monitors from the new office for daily quality control measurements is not sufficient. While new equipment may be less likely to have wear-and-tear issues that could affect performance, it is still subject to potential inaccuracies and must be included in the daily quality control routine.
Choice C reason:
Similarly, excluding the new monitors and only checking those from the old medical office would neglect the possibility of inaccuracies in the newer equipment. All monitors, irrespective of their age, can experience calibration drift or other issues that affect their performance.
Choice D reason:
Opting not to perform daily quality control measurements on any of the blood glucose monitors would be against the recommended guidelines and could lead to inaccurate blood glucose readings. This could have serious implications for patient health, particularly in the management of diabetes.

Correct Answer is D
Explanation
Choice A Reason:
The right antecubital fossa is not the optimal site for blood collection in this case because the presence of a shunt in the right forearm can complicate the procedure and potentially damage the shunt, which is a critical access point for dialysis treatments.
Choice B Reason:
The right hand should also be avoided for blood collection due to the shunt placement in the right forearm. Using the same arm as the shunt for venipuncture could lead to complications such as infection, clotting, or accidental damage to the shunt.
Choice C Reason:
The left antecubital fossa might seem like a viable option; however, with an IV placed in the left hand, it is generally recommended to avoid using the same limb for blood collection to prevent contamination of the sample and reduce the risk of infection at the IV site.
Choice D Reason:
Capillary collection from the left hand is the most appropriate choice in this scenario. It avoids the arm with the shunt and the IV, reducing the risk of complications. Capillary blood collection is a suitable alternative when venipuncture sites are limited, and it can provide an adequate sample for a CBC.
Correct Answer is B
Explanation
Choice A Reason:
Wrapping the site with a heel warmer for 30 minutes is a preparatory step before the heel stick procedure. It is used to increase blood flow to the area to make the collection easier. However, it is not the action to take after the blood has been collected. The heel warmer should be removed before performing the heel stick.
Choice B Reason:
Wiping away the first drop of blood is the correct procedure. The initial drop may be contaminated with tissue fluids or alcohol if the site was cleaned prior to the stick, which can affect the accuracy of the test results. Therefore, the first drop should be wiped away, and subsequent blood should be used for the PKU test.
Choice C Reason:
Keeping a pressure dressing on the site for the entire day is not necessary and is not part of the standard heel stick procedure. After the blood is collected, a small bandage is typically applied to stop any bleeding. The site should be monitored for a short time for any signs of continued bleeding or bruising, but a pressure dressing for the day is excessive.
Choice D Reason:
Targeting the central arch area of the foot for the heel stick is incorrect and can be harmful. The recommended area for a heel stick is the lateral portions of the heel to minimize discomfort and avoid injury to the bone or nerves. The central arch area should be avoided to prevent potential harm.
