Mr. Frank McGuire is a 90-year-old former industrial worker who has lost 30 pounds over the past 4 years, resulting in a frail body. He has been diagnosed as having Parkinson's disease as well as congestive heart failure. Mr. McGuire is having is blood collected in the nursing home where he now resides; his physician has ordered a potassium level, a hemoglobin level, and a PT/INR test because he is on Coumadin. How should the patient be approached for the blood collection?
The elderly person is most likely to have fragile veins and this it is best to collect the blood by venipuncture using a butterfly needle and small vacuum tubes to decrease the impact of the vacuum pressure on his fragile veins
Mr. Frank McGuire is a 90-year-old former industrial worker who has lost 30 pounds over the past 4 years, resulting in a frail body. He has been diagnosed as having Parkinson's disease as well as congestive heart failure. Mr. McGuire is having is blood collected in the nursing home where he now resides; his physician has ordered a potassium level, a hemoglobin level, and a PT/INR test because he is on Coumadin. What is the most appropriate blood collection equipment to use?
The coagulation tube (light-blue evacuated tube) needs to be collected first for the PT/INR. A "dummy" red topped tube should be collected prior to the light-blue topped tube since the butterfly needle with the tubing will be the needle of choice for the venipuncture. The serum tube should be collected next for potassium. The EDTA tube for the hemoglobin test is collected as the last tube

As people age, changes occur that can make collecting a blood sample more challenging. This would include loss of hearing, sight, and memory which may all change how the patient reacts to the healthcare worker. In addition, changes in the integrity of the skin and connective tissue may make the actual collection more difficult as scarring and sclerosis cause tougher veins, and fragile skim allowing more rolling of the vessels.
What are some changes that may affect the ability to collect a blood sample from an elderly person?
The depth of the puncture must be less than 2.0mm hence correct puncture devices must be used. The end of the heel should not be used as it increased the risk of puncturing the heel bone. The fleshy parts to each side of the heel are preferred sites. The first drop should be wiped off after puncture. Do not touch the puncture site with any of the collection equipment during the procedure. The site should be held with sterile gauze after the procedure. No bandages should be placed on the site.

A two year old is likely to be fearful and since they are in the ER, they will be feeling poorly. The phlebotomist should introduce themselves to the child and family/caregiver and describe the procedure in simple terms. When talking to the child, the phlebotomist should give simple commands the child can follow. They should work slowly and calmly. They should suggest the parent or guardian hold the child and offer comforting items such as a pacifier, blanket, or toy. They should make sure the child is kept warm, and keep the parent present and a part of the process if possible
Working on the evening shift, the phlebotomist was called to the emergency department to collect blood from a 2 year old. The orders included CBC, blood culture, electrolytes, glucose, and BUN. How should the phlebotomist approach the patient and family?
The phlebotomist could employ the help of other healthcare workers to hold the child for the procedure. If absolutely necessary, the child can be swaddled or restrained through other methods. If time is allowed, EMLA could be used to minimize the pain
Working on the evening shift, the phlebotomist was called to the emergency department to collect blood from a 2 year old. The orders included CBC, blood culture, electrolytes, glucose, and BUN. The child in this case is very sick and agitated. The parents are distraught and appear unable to provide calm support to the child. What could be recommended to the phlebotomist?
Using a winged infusion set with a smaller needle is recommended. The phlebotomist will need to collect either sterile yellow tubes or tubes with culture media first depending on the hospital's policies. The CBC will be collected in an EDTA (lavender) tube and the chemistry (electrolytes, glucose, and BUN) will be collected in a heparin (green) tube. Pediatric size tubes can be used for the hematology and chemistry tests to decrease the blood volume removed from the child. Using a syringe is also a possibility.
