  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?

    • Where are the sites of injection? 

      • Gluteus medius 

      • Vastus lateralis (preferably for infant)

      • Deltoid muscle 

    • What muscle is targeted in the injection? 

      • Vastus lateralis 

    • Write down its origin, insertion and action

      • Origin: Greater trochanter and linea aspera of femur

      • Insertion: Patella via quadriceps tendon and then tibial tuberosity via patellar ligament

      • Action: All four heads extend leg at knee joint; rectus femoris muscle acting alone also flexes thigh at hip join

    • How do you locate this area?

      • Thigh’s lateral aspect 

 

  1. 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?

    • Which muscle is the preferred site for IM injection in this case?

      • Deltoid muscle 

    • Write down its origin, insertion and action.

      • Origin: Acromial extremity of clavicle (anterior fibers), acromion of scapula (lateral fibers), and spine of scapula (posterior fibers).

      • Insertion: Deltoid tuberosity of humerus.

      • Action: Lateral fibers abduct arm at shoulder joint; anterior fibers flex and medially rotate arm at shoulder joint; posterior fibers extend and laterally rotate arm at shoulder joint.

    • How do you locate this area?

      • It covers the shoulder joint which forms a round contour. The needle should enter the center of the triangular muscle.
