A patient's urine tests positive for glucose. The doctor asks you to confirm this finding. Which of the following would BEST confirm this finding?

Correct Answer: C

Rationale: To confirm glucosuria, the most appropriate method is to run a Clinitest. Clinitest tablets are specifically designed to detect glucose in urine samples. This test is particularly useful when the urine is discolored, making it challenging to accurately assess the color change.\n Choice A, using a hand-held glucometer, is not the standard method for confirming glucose in urine; these devices are primarily used for blood glucose monitoring.\n Choice B, having another Medical Assistant perform a repeat dipstick test, may not provide a more definitive confirmation as dipstick tests can sometimes yield false positives or be less accurate compared to other methods like the Clinitest.\n Choice D, running an Acetest, is used to detect ketones in the urine, not glucose. Ketones are typically associated with conditions like diabetic ketoacidosis, which is different from glucosuria.

Correct Answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

Correct Answer: C

Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.

Correct Answer: B

Rationale: In the scenario where a patient is sweating and anxious, it is important to assess for signs of potential syncope (fainting) while proceeding with the blood draw. If the patient does not exhibit signs of fainting, the phlebotomy procedure can be performed safely. Postponing the procedure may not address the patient's anxiety and inconvenience them. Having the physician draw the blood is not necessary if the phlebotomist can handle the situation effectively.

Correct Answer: A

Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
