Good day to everyone in this forum! Here are my answers for the third activity. Thank you!
1) It is immunization day at the health center. The first patient is a 2-month old well female infant who is scheduled for the following vaccinations: pneumococcal conjugate vaccine (PCV), pentavalent vaccine (Penta) and oral polio vaccine. PCV and Penta are given via intramuscular route. Where are the sites of injection? What muscle is targeted in the injection? Write down its origin, insertion and action. How do you locate this area?
The site for the injection of the pneumococcal conjugate vaccine and the pentavalent vaccine is the anterolateral thigh area of the infant ( Wolicki & Miller, n.d.). The muscles targeted in this injection are the Vastus lateralis which originates from the greater trochanter and linea aspea of the femur. It then inserts into the patella via the quadriceps tendon and then tibial tuberosity via the patellar ligament. The vastus lateralis is one of the four heads included in the quadriceps enabling it to extend the leg at the knee joint (Tortora & Derrickson, 2017). This area can be located in the thigh area of the infant specifically oriented in front of the body but away from the midline which is basically more on the side of the infant’s thigh.
2) The baby’s 65-year-old grandfather also came to the center because influenza vaccine is being offered to senior citizens. The flu vaccine is given intramuscularly. Which muscle is the preferred site for IM injection in this case? Write down its origin, insertion and action. How do you locate this area?
The preferred site for intramuscular injection of influenza vaccines for adults is the deltoid muscle. This muscle originates from the lateral part of the clavicle, commonly known as the collarbone, as well as the spine and shoulder blade. From here, it inserts into the deltoid tuberosity of the humerus or the long bone in the upper arm (Tortora & Derrickson, 2017). Hence, during the administration of the flu vaccine to the 65-year-old grandfather, the deltoid muscle can be located in the upper arm, more specifically above the auxiliary or the armpit level and approximately two inches below the bony prominence at the end of the shoulder.
